Before McHUGH, MURPHY, and CARSON, Circuit Judges.
                 _________________________________

       In 2016, the International Brotherhood of Electrical Workers, Local 225 (the

Union) filed a petition with the National Labor Relations Board (the Board) seeking to

represent certain purchasing employees of Wolf Creek Nuclear Operating Corporation,

Buyers I, II, and III, and the Lead Buyer (the Buyers). Wolf Creek opposed the Union’s

petition, claiming the Buyers were managerial employees—as decided by a previous

Regional Director’s decision in 2000—and therefore were excluded from coverage under

       *
         This order and judgment is not binding precedent, except under the doctrines of
law of the case, res judicata, and collateral estoppel. It may be cited, however, for its
persuasive value consistent with Fed. R. App. P. 32.1 and 10th Cir. R. 32.1.
the National Labor Relations Act (the Act). After a series of appeals and remands, the

Regional Director concluded there had been material changes in circumstances that

warranted relitigating the Buyers’ managerial status and, upon reconsideration, found the

Buyers were nonmanagerial employees. Consistent with the Board’s decision, the Buyers

voted on and approved representation by the Union.

       Wolf Creek refused to bargain with the Union on behalf of the Buyers. As a result,

the Board found Wolf Creek had engaged in unfair labor practices, in violation of

sections 8(a)(1) and (a)(5) of the Act. The Board then filed an enforcement application

with this court. Wolf Creek opposes enforcement, arguing the 2000 decision should have

been given res judicata effect and that the Buyers are managerial employees. Reviewing

for substantial evidence, we conclude the Regional Director’s findings of changed

circumstances and nonmanagerial status were supported. Therefore, exercising

jurisdiction under 29 U.S.C. § 160(e), we GRANT the application for enforcement.

                                 I.     BACKGROUND

                                  A. Factual History1

       The Buyers procure all goods and services, except nuclear fuel, for Wolf Creek.

To qualify as a Buyer, an individual must meet a combination of educational and

professional criteria, with higher levels of both required for each successive level of

Buyer—Buyer I, Buyer II, Buyer III, and Lead Buyer. The Buyers are required to train

       1
        This factual history is taken from the Regional Director’s decisions: Decision &
Direction of Election, No. 14-RC-168543 (Feb. 16, 2016) [hereinafter 2016 Decision],
and Supplemental Decision, No. 14-RC-168543 (May 9, 2017) [hereinafter 2017
Decision]. We address Wolf Creek’s challenge to these findings in the discussion section.

                                             2
for and receive certifications from the Institute of Supply Management and to keep

current with continuing education requirements. Wolf Creek pays for the initial training

and certification and offers classes to cover the continuing education requirements. All

Buyers report to a supervisor and none of the Buyers supervise any other employee.

       Wolf Creek has adopted an Administrative Control Procedure (ACP) that

establishes guidelines for procuring materials. The ACP applies not only to the Buyers

but also to other employees involved in the procurement process. The procurement

process also utilizes EMPAC, a computer system designed to streamline purchases. To

put the parties’ arguments in context, we provide a brief overview of the procurement

process at Wolf Creek.

       The procurement process begins when an employee sends a requisition to the

purchasing department via EMPAC. The requisition includes the item requested, the

quantity needed, the item’s authorized purchase price, and previous purchase prices. All

requisitions must be submitted by an employee with purchasing authority and authorized

by a supervisor or manager from the requesting department. Management assigns

employees different levels of purchasing authority. The Buyers are not involved in

creating requisitions or authorizing employees to submit requisitions.

       After the requisition is submitted, the Buyers’ supervisor assigns the requisition to

a Buyer based on the type of item requested. The Buyer’s purchasing authority for the

requisition is dictated by the requestor’s level of purchasing authority. The Buyer has no

authority to purchase without a proper requisition and may not exceed the requestor’s

                                             3
purchasing authority. The Buyer is responsible for ensuring there is proper authorization

before completing any purchase.

       The Buyer’s first step after receiving a requisition is to determine whether the item

should be competitively bid. Competitive bidding is required for purchases expected to

exceed $50,000, if multiple approved suppliers of the item exist. The Buyers have the

discretion to, and often do, competitively bid purchases under $50,000.

       Once the Buyer chooses to competitively bid an item, the ACP requires “the Buyer

[to] determine[] the suppliers from whom to solicit bids, based on commercial, technical,

and/or quality considerations.” 2016 Decision at 5. Generally, the Buyer will begin by

generating a list of potential suppliers from EMPAC, which will include the Original

Equipment Manufacturer and prior suppliers. If the item is safety-related, the Buyer is

required to use suppliers from a specific pre-approved list.

       After compiling the list of potential suppliers, the Buyer uses EMPAC to generate

a Request for Quotation (RFQ) and sends the RFQ to potential suppliers. EMPAC allows

the Buyer to populate the RFQ form with standard clauses and information. If a supplier

requests an exception to a safety-related RFQ, the Buyer is required to seek the

procurement engineer’s approval for the exception. Where the exception is not

safety-related, the Buyer will generally seek approval from the requestor, although the

Buyer is not required to do so.

       Once the Buyer receives the bids, the Buyer enters the information into EMPAC

so EMPAC can perform a bid analysis. Generally, the Buyer selects the lowest bidder,

but can consider delivery time, cost of freight, and safety concerns. In selecting the

                                             4
winning bid, the Buyer can rely on his or her “background, experience, training,

certifications, and knowledge.” Id. at 6. If the Buyer does not select the lowest bid, the

Buyer must enter the reason into EMPAC.

       Regardless of whether the item was competitively bid, if the purchase price

exceeds the original requisition price, but by less than $1,000 per line item, the Buyer has

authority to make the purchase. If the price is more than $1,000 per line item over the

original requisition price, the Buyer must receive authorization from the requestor.

       After a supplier is selected, the Buyer uses EMPAC to draft a purchasing order.

EMPAC allows the Buyer to select terms and conditions for the purchasing order and

EMPAC then issues the order. EMPAC warns the Buyer if terms and conditions are

missing from the purchasing order, but the Buyer can choose to issue the purchasing

order anyway. EMPAC also requires the Buyer to confirm the Buyer has funding

approval before creating the purchasing order. By issuing the purchasing order, the Buyer

commits Wolf Creek’s funds for the purchase.

       After submitting purchasing orders, the Buyer’s final responsibility is to arrange

shipping. The Buyer may select the freight carrier, but the Buyer is often restricted by

alliance agreements2 with other plants. The Buyer is not responsible for negotiating those

agreements.

       2
        Wolf Creek enters into alliance agreements with other power plants that specify
preferred suppliers for purchases ranging from freight to gaskets to electrical purchases in
exchange for better rates.

                                              5
                                 B. Procedural History

       In 2000, the Regional Director issued a decision in case number 17-UC-210 in

which it granted Wolf Creek’s petition to clarify the existing bargaining unit and to

exclude the Buyers as managerial employees. Decision, Order & Clarification of

Bargaining Unit at 22–23, No. 17-UC-210 (May 4, 2000) [hereinafter 2000 Decision].

The Union did not appeal the 2000 Decision to the Board.

       Sixteen years later, in 2016, the Union3 filed a petition with the Board seeking to

represent the Buyers as part of the bargaining unit, thereby initiating case 14-RC-168543.

The Regional Director concluded he was not required to give res judicata effect to the

2000 Decision because “the Board did not make an official or final ruling on the issue.”

2016 Decision at 2–3. Considering the issue anew, the Regional Director found the

Buyers were not managerial employees and could be part of the bargaining unit. He

therefore directed that a secret ballot election be held for the Buyers to decide if they

wanted to be represented by the Union. The Buyers voted to join the Union.

       Wolf Creek requested Board review of the Regional Director’s refusal to give res

judicata effect to the 2000 Decision and his conclusion that the Buyers were not

managerial employees. On review, the Board ruled the 2000 Decision was final for

preclusion purposes and would have preclusive effect “unless the party seeking

relitigation of the previously decided issue satisfies its burden of presenting new factual

       3
         The Union changed from Local 304 in 2000 to Local 225 in 2016. The parties do
not discuss this change, and we therefore presume it has no effect on the res judicata
analysis.

                                              6
circumstances that would vitiate the preclusive effect of the earlier ruling.” Wolf Creek

Nuclear Operating Corp. & Int’l Bhd. of Elec. Workers, Local 225, 365 N.L.R.B. No. 55,

at 1–2 (Apr. 7, 2017) [hereinafter 2017 Remand Order]. The Board remanded the case to

the Regional Director to consider whether there was a sufficient change in circumstances

to warrant revisiting the Buyers’ managerial status.

       On remand, the Regional Director reopened the record and concluded there had

been a material change in circumstances sufficient to warrant reconsidering the Buyers’

managerial status. He thus refused to give preclusive effect to the 2000 Decision. The

Regional Director also reaffirmed the 2016 Decision’s conclusion that the Buyers were

not managerial employees.

       Wolf Creek again sought Board review, but the Board denied the request because

“[Wolf Creek] raises no substantial issues warranting review.” Order, No. 14-RC-168543

(Oct. 27, 2017) [hereinafter 2017 Denial Order]. In a footnote, however, the Board noted

its agreement with the decision not to give preclusive effect to the 2000 Decision.

       In July 2016, the Union filed a charge alleging Wolf Creek had engaged in unfair

labor practices by refusing to bargain with the Union despite the Union’s certification as

the collective bargaining representative for the Buyers. Wolf Creek Nuclear Operating

Corp. & Int’l Bhd. of Elec. Workers, Local 225, 366 N.L.R.B. No. 30, at 1–2 (Mar. 13,

2018) [hereinafter 2018 Decision]. Based on that charge, General Counsel for the NLRB

filed a complaint in November 2017 alleging Wolf Creek was in violation of sections

8(a)(1) and (a)(5) of the Act. The Board concluded Wolf Creek improperly refused to

bargain and granted summary judgment to the General Counsel. Pursuant to 29 U.S.C.

                                             7
§ 160(e), the Board filed an application with this court for enforcement of the 2018

Decision.4

                                   II.    DISCUSSION

       Wolf Creek opposes the application for enforcement, challenging both the

conclusion that there was a material change in circumstances and the conclusion that the

Buyers are nonmanagerial employees. We begin by discussing three relevant standards:

(1) the general standard of review governing an application for enforcement; (2) the

standard for determining whether an employee falls within the managerial exclusion of

the Act, and; (3) the standard dictating when the Board can revisit a prior final order. We

then address the Regional Director’s finding of a material change in circumstances

permitting reconsideration of the 2000 decision. Concluding that there were material

changes in circumstances, we next discuss the Regional Director’s finding that the

Buyers do not fall within the managerial exclusion.

                            A. General Standard of Review

       “In reviewing an NLRB order, we grant enforcement if we find that the Board

correctly interpreted and applied the law, and if its factual findings are supported by

       4
         Wolf Creek’s challenge in this case is limited to the determinations made in the
2016 Decision and 2017 Decision. Board certification proceedings normally “are not
directly reviewable in the courts” unless “the dispute concerning the correctness of the
certification eventuates in a finding by the Board that an unfair labor practice has been
committed as, for example, where an employer refuses to bargain with a certified
representative on the ground that the election was held in an inappropriate bargaining
unit.” Boire v. Greyhound Corp., 376 U.S. 473, 476–77 (1964). In reviewing an unfair
labor practice determination, as we do here, the Act provides for full judicial review of
the prior certification decision. Id.

                                             8
substantial evidence in the record as a whole.” NLRB v. Greater Kan. City Roofing, 2
F.3d 1047, 1051 (10th Cir. 1993); see also 29 U.S.C. § 160(e) (mandating the Board’s

factual findings are conclusive if “supported by substantial evidence on the record

considered as a whole”). “As to questions of law, we generally afford the Board's

determinations great weight, and uphold their determinations if within reasonable

bounds.” Greater Kan. City Roofing, 2 F.3d at 1051 (internal quotation marks omitted).

       As to factual findings, “[t]he scope of judicial review of an NLRB record on an

enforcement application compels careful consideration of all of the evidence, including

whatever fairly detracts from the Board’s findings and conclusions.” NLRB v. J.D. Indus.

Insulation Co., 615 F.2d 1289, 1292 (10th Cir. 1980). But the substantial evidence test

gives the NLRB “the benefit of the doubt” and “requires not the degree of evidence

which satisfies the court that the requisite fact exists, but merely the degree which could

satisfy a reasonable factfinder.” Allentown Mack Sales & Serv. v. NLRB, 522 U.S. 359,

377 (1998). We may not “displace the Board's choice between two fairly conflicting

views, even though [we] would justifiably have made a different choice had the matter

been before [us] de novo.” Universal Camera Corp. v. NLRB, 340 U.S. 474, 488 (1951).

We must respect the Board’s findings unless we “cannot conscientiously find that the

evidence supporting that decision is substantial.” Id.

         B. Standard for Determining Whether Employees Are Managerial

       Managerial employees are not expressly excluded from coverage under the Act.

See NLRB v. Yeshiva Univ., 444 U.S. 672, 682 (1980). But there is a “judicially implied

exclusion for ‘managerial employees’ who are involved in developing and enforcing

                                             9
employer policy.” Id. This exclusion grew out of the concern “[t]hat an employer is

entitled to the undivided loyalty of its representatives.” Id. In recognizing the exclusion,

the Supreme Court noted the Act’s legislative history, which “strongly suggests that there

also were other employees, much higher in the managerial structure, who were . . .

regarded as so clearly outside the Act that no specific exclusionary provision was thought

necessary.” NLRB v. Bell Aerospace Co., Div. of Textron, Inc., 416 U.S. 267, 283 (1974).

       “[T]he question whether particular employees are ‘managerial’ must be answered

in terms of the employees’ actual job responsibilities, authority, and relationship to

management.” Id. at 290 n.19.

       Managerial employees are defined as those who “formulate and effectuate
       management policies by expressing and making operative the decisions of
       the employer.” These employees are “much higher in the managerial
       structure” than those explicitly mentioned by Congress, which “regarded
       [them] as so clearly outside the Act that no specific exclusionary provision
       was thought necessary.” Managerial employees must exercise discretion
       within, or even independently of, established employer policy and must be
       aligned with management. Although the Board has established no firm
       criteria for determining when an employee is so aligned, normally an
       employee may be excluded as managerial only if he represents management
       interests by taking or recommending discretionary actions that effectively
       control or implement employer policy.

Yeshiva Univ., 444 U.S. at 682–83 (alteration in original) (citations omitted) (quoting Bell

Aerospace, 416 U.S. at 288, 283, 286–87). Managerial employees include “‘those who

formulate, determine, and effectuate an employer’s policies,’ and those who have

discretion in performance of their jobs, but not if th[at] discretion must conform to an

employer’s established policy.” Bell Aerospace, 416 U.S. at 288 n.16 (citation omitted)

(quoting Retail Clerks Int’l Ass’n v. NLRB, 366 F.2d 642, 645 (D.C. Cir. 1966)).

                                             10
  C. Standard for Determining Whether the Board Can Reconsider a Prior Ruling

       The Board “has chosen to promulgate virtually all the legal rules in its field

through adjudication rather than rulemaking.” Allentown Mack Sales & Service, 522 U.S.

at 374. And its adjudication is subject to the same requirement of reasoned

decisionmaking as applies to rulemaking. Id. Therefore, the Board “must be required to

apply in fact the clearly understood legal standards that it enunciates in principle.” Id. at

376.

       The Board “explicitly held that Board decisions and rulings in representation cases

have preclusive effect in subsequent representation cases.” 2017 Remand Order at 1. The

party seeking relitigation of the issue (here, the Union) has the “burden of presenting new

factual circumstances that would vitiate the preclusive effect of the earlier ruling.” Id. at

2. This burden is not, however, “an onerous one,” as it merely requires pointing to “one

material differentiating fact.” Id. at 3 n. 7 (quoting Miller’s Ale House, Inc. v. Boynton

Carolina Ale House, LLC, 702 F.3d 1312, 1319 (11th Cir. 2012)). To overcome the

preclusive effect of a prior decision, “circumstances [must] have changed in a way that

would materially alter the analysis of the [B]uyers’ managerial status.” Id. at 3. So, it is

necessary to “examine any factual changes in context and in light of the relevant statutory

question.” Id. We undertake that analysis now.

                         D. Material Change in Circumstances

       The Regional Director concluded there were three material changes in

circumstances that warranted overcoming res judicata and relitigating the Buyers’

managerial status. We begin by discussing Wolf Creek’s specific challenges to each of

                                              11
the changes in circumstances. We then address whether those changes overcome the res

judicata effect of the 2000 Decision.

   Substantial Evidence Supporting Changes

          The three material changes found by the Regional Director to warrant relitigation

of the Buyers’ managerial status are that: (1) changes to EMPAC altered the Buyers’ role

in the procurement process, (2) Wolf Creek reduced the frequency of competitive

bidding, and (3) the Buyers are less involved in evaluating responses to RFQs. Wolf

Creek challenges each of these material changes. In this section, we first consider Wolf

Creek’s challenges to each change individually, including specifically whether there is

substantial evidence to conclude the change exists. In the following section, we discuss

whether these changes were material and warranted relitigating the Buyers’ managerial

status.

          a. Updates to EMPAC

          The first material change in circumstances identified by the Regional Director was

the technological upgrades to EMPAC. The Regional Director recognized that “standing

alone, technological changes are insufficient to establish material changes to a job

classification.” 2017 Decision at 6. But the Regional Director focused on how EMPAC’s

evolution allows Wolf Creek to “integrate its procurement procedures and its

procurement software, and thus, regulate and restrict the [B]uyers’ discretionary actions.”

Id. The Regional Director noted, “information that was once available only in the mind of

a seasoned buyer or maintained in hardcopy” is now readily accessible to the Buyers and

other employees. Id. at 7. And EMPAC now has pop-up warnings with procurement

                                              12
policies and assists the Buyers “in including necessary clauses in an RFQ or purchase

order.” Id. The Regional Director also found that EMPAC performs some functions for

which the Buyers were previously responsible, such as analyzing and calculating bids and

shipping terms. As a result of these changes, the Regional Director found the Buyers’

“role as one of the final gatekeepers in the procurement process has been diminished.” Id.

The Regional Director concluded that “changes to the EMPAC system, largely a result of

technical innovation, have fundamentally limited the [B]uyers’ discretion” and constitute

a material change in circumstances. Id. at 6.

       Wolf Creek does not argue the record lacks substantial evidence to support the

Regional Director’s findings regarding changes to EMPAC; Wolf Creek effectively

acknowledges those changes exist. Instead, Wolf Creek asserts the Regional Director’s

determination is erroneous because “the Board has long held that advances in technology

are generally insufficient to warrant a change in managerial status.” Wolf Creek’s Br. at

24. And Wolf Creek contends the Regional Director failed to consider these changes

against the criteria for evaluating managerial status—“the underlying nature of the job

and the independent discretion maintained in the position.” Id. Under that criteria, Wolf

Creek contends that “[t]he source of information is irrelevant,” id., and the rules built into

EMPAC “have always been in place and the Buyers have always been responsible for

following them,” id. at 25–26.

       At least one of the Board members agreed with Wolf Creek’s position. In denying

review of the 2017 Decision, one Board member noted he did not find the changes in

EMPAC material because they “merely automated certain functions and reminded Buyers

                                             13
of preexisting boundaries of their discretionary authority without actually further

diminishing that authority.” 2017 Denial Order at n.1.

       Because the Regional Director found two additional material changes in

circumstances, we need not address whether the changes to EMPAC, standing alone,

could provide substantial evidence of a material change in circumstances. Indeed, we

need not consider the EMPAC changes in our analysis at all because, as we now discuss,

substantial evidence supports the other material changes found by the Regional Director,

and those changes warrant relitigation of the Buyers’ managerial status.

       b. Reduction in competitive bidding

       Separate from the changes to EMPAC, the Regional Director found a material

change in circumstances in the decreased use of competitive bids and, correspondingly,

the Buyers’ discretion. While the Regional Director recognized competitive bidding is

still part of the Buyers’ duties, he emphasized the decline in that practice based on Wolf

Creek’s increased use of single-source suppliers.

       According to Wolf Creek, the Buyers are still responsible for deciding whether to

competitively bid an item and for the competitive bidding process. Wolf Creek also notes

that some items, such as safety-related items, have never been appropriate for competitive

bidding. But Wolf Creek concedes that “the number of purchases subject to competitive

bidding has declined.” Wolf Creek’s Br. at 27. And there is substantial evidence in the

record to support the Regional Director’s finding of a significant decrease in competitive

bidding.

                                             14
       While the record does not indicate the percentage of procurements previously

subjected to competitive bidding, in 2000 the Regional Director noted there were only

“limited situations” where items over $5,000 were not competitively bid. 2000 Decision

at 20. By 2017, only about 10% of all purchase orders were competitively bid. A Buyer

who began in 1997 testified that the amount of competitive bidding has progressively

declined.

       Testimony also indicates that multiple factors impacted this decline. First, Wolf

Creek’s plant is now more than thirty years old and often only a single company still sells

the specific equipment needed. Second, with respect to safety-related items, the Buyers

can seek bids only from approved suppliers, and there is often just a single approved

supplier for the item.5 Finally, Wolf Creek has negotiated several alliance agreements that

encourage purchasing items from a designated supplier.

       In short, there is substantial evidence in the record supporting the Regional

Director’s conclusion that there was a significant decrease in competitive bidding after

the 2000 Decision.

       c. Reduced involvement in RFQ process

       Finally, the Regional Director found that the Buyers are less involved in

evaluating responses to RFQs and in selecting the ultimate supplier than in 2000. Except

for routine or low-cost purchases, the Buyers now “customarily consult with the

       5
        In 2000, the Buyers were also limited to approved suppliers for safety-related
items. But there is no indication in the 2000 Decision that safety-related items often had
only one approved supplier.

                                            15
requisitioning department, the procurement engineering department, or a manager to

identify a preferred supplier.” 2017 Decision at 8.

       To challenge this finding, Wolf Creek argues the Buyers are still involved in

evaluating responses to RFQs and in making the ultimate decision to award a purchase to

a supplier. Wolf Creek also contends that while the Buyers do frequently consult with

others, this process has not changed since 2000. In support, Wolf Creek cites to the

testimony of a Buyer who admits that purchasing safety-related items has always been

governed by special procedures. Nothing in the cited testimony, however, discusses

evaluating responses to RFQs or consulting with other departments during that process.

       We have not located, and Wolf Creek has failed to point us to, any evidence that

the Buyers in 2000 routinely consulted with other departments when selecting a winning

bid outside of the safety-related context. In 2000, the Regional Director found the Buyers

“perform[ed] a commercial evaluation to determine the most beneficial bid based on

price, delivery, performance schedule, payment terms, warranties, exceptions, etc.” 2000

Decision at 21. At that time, the Buyers used a bid evaluation template to list the

pertinent attributes side-by-side and selected the best option. The Buyers then selected

the winning bidder without seeking prior approval, even for safety-related items. Notably

absent from the Regional Director’s 2000 ruling is any mention of the Buyers consulting

with anyone before making the decision.

       Conversely, there is significant testimony from the Buyers in the 2016 and 2017

proceedings establishing that they now routinely consult with others when evaluating

bids. For example, there are many purchases that require the Buyers to check with system

                                             16
engineering to ensure the response to the RFQ will meet its needs. Other times, the Buyer

will confer with the requestor about the bids and the necessary timelines. In response to

the general question, “when you do competitive bidding, it is up to the Buyer to make the

decision who won the bid, right?” a Buyer responded, “Well, I -- I’d say we consult the

requestor.” Tr. at 329.

       Another Buyer testified regarding when the Buyers will select the winning bid

without input from others. That Buyer explained there are certain technical purchases that

require the requesting department to review the bids and assess the technical

requirements, the quality, the price, and the timeframe to determine which bid to accept.

But there are certain routine or low-cost purchases where the Buyer will simply choose

the lowest bid or a slightly higher bid that ships faster. Frequently, even those decisions

are run through the Buyer’s superior. And the Buyer will often go back to the requestor

before making those decisions.

       Admittedly, there is some contradictory testimony. A recently retired Buyer

testified about performing commercial bid evaluations as a necessary part of the process.

Although approval is needed to add a supplier for safety-related items, the Buyer would

send out RFQs to unapproved suppliers and, if the response was favorable after a

commercial evaluation, the Buyer would seek approval to add the supplier to the

approved list. The Buyer also testified that the general process for evaluating responses to

RFQs was substantially the same as when she started in the late 1980s.

       Despite this contradictory testimony, there was ample evidence from which the

Regional Director could conclude that, although not mandated by the procedures, the

                                             17
Buyers would typically consult with superiors in the procurement department or with the

requestor when awarding the bid—except for routine or low-cost purchases. We may not

“displace the Board’s choice between two fairly conflicting views.” Universal Camera,
340 U.S. at 488. Thus, there is substantial evidence supporting the Regional Director’s

finding of a change in circumstance based on the Buyers’ diminished role in evaluating

RFQs.

   Materiality of the Changes in Circumstance

        Excluding the changes to EMPAC, we are left with the Regional Director’s

findings that the reduction in competitive bidding and the minimized involvement in

selecting suppliers in response to RFQs were each material changes in circumstances that

warranted relitigating the Buyers’ managerial status. We consider each of these changes

below, concluding the Regional Director’s determination that they justified

reconsideration of the Buyers’ managerial status is supported. In reaching that

conclusion, we first frame the inquiry in terms of the statutory question. We next review

the 2000 Decision to assess the basis of the Regional Director’s finding that the Buyers

were acting as managerial employees. Then we consider each change in circumstances to

determine whether the change would alter that analysis.6

        6
         Although the parties do not directly address the standard of review applicable to
the materiality of a change, Wolf Creek treats the substantial evidence question as distinct
from the issue of whether any such change is material. See Wolf Creek’s Br. at 23
(“While some of these alleged changes were not supported by evidence in the record,
even if they were, they relate to changes in the manner in which Buyers perform their job
duties, not to changes in the duties themselves or to the underlying nature of the Buyer
positions. Changes in the manner of performing a job do not warrant reclassification if

                                            18
          a. The statutory question and 2000 Decision

       Whether a material change in circumstances exists must be considered “in light of

the relevant statutory question.” 2017 Remand Order at 3. The statutory question in this

case is: Are the Buyers covered by the Act? So, the change is material if it “would

materially alter the analysis of the [B]uyers’ managerial status.” Id. That analysis, in turn,

involves evaluating “the employees’ actual job responsibilities, authority, and

relationship to management,” Bell Aerospace, 416 U.S. at 290 n.19, to determine whether

the employees “exercise discretion within, or even independently of, established

employer policy and . . . [are] aligned with management,” Yeshiva Univ., 444 U.S. at 683.

       In 2000, the Regional Director applied this analytical framework in concluding the

Buyers were managerial employees. Specifically, the Regional Director noted “[t]he

Buyers exercise independent discretion when they locate vendors without reliance upon

pre-approved lists” and “select a vendor without supervisory approval.” 2000 Decision at

23. But between 2000 and 2017, there was a material reduction in both the quantity and

quality of the Buyers’ exercise of that discretion. See 2017 Decision at 9 (“Buyers now

the underlying duties remain the same.” (emphasis added)). Implicitly, Wolf Creek briefs
the issue as a mixed question of law and fact.
       We need not decide whether the materiality of a change in circumstance is a
question of fact, a mixed question, or a question of law because Wolf Creek’s arguments
fail under even the least deferential of these standardsthat applicable to a question of
law. Therefore, we will assume, without deciding, that we review the materiality of a
change in circumstances to determine whether “the Board correctly interpreted and
applied the law,” affording its legal “determinations great weight, and uphold[ing] their
determinations if within reasonable bounds.” NLRB v. Greater Kan. City Roofing, 2 F.3d
1047, 1051 (10th Cir. 1993) (internal quotation marks omitted).

                                             19
only infrequently locate and select venders without first consulting a manager or

members of the department responsible for a requisition. And, although in some

circumstances [the B]uyers continue to make vendor decisions on routine and cheap

purchases, they do so guided by [Wolf Creek’s] detailed procedures and nearly always

select either the lowest bidder or the supplier who can provide the materials within the

requisitioning departments timeline.”).

          b. The decrease in competitive bidding

       The decrease in competitive bidding corresponds to a decrease in the frequency

with which the Buyers locate and select vendors without preapproval. Alliance

agreements that specify a single supplier decrease the Buyers’ discretion to locate

vendors without reliance on pre-approved lists or to select a vendor without supervisory

approval. And the age of the power plant often results in only one available supplier.

There is no discretion involved when the Buyers award the contract to the vendor

approved through an alliance agreement or the sole vendor from which the products are

available. This change in circumstances relates to the Buyers’ “actual job responsibilities,

authority, and relationship to management,” Bell Aerospace, 416 U.S. at 290 n.19, and to

whether they “exercise discretion within, or even independently of, established employer

policy and . . . [are] aligned with management,” Yeshiva Univ., 444 U.S. at 683.

Accordingly, the decrease in competitive bidding would alter the analysis of the statutory

question and is a material change.

       Wolf Creek argues, however, that the admitted decrease in competitive bidding

makes the Buyers more important—and able to exercise more discretion—because when

                                            20
there is no competitive bidding they must ensure a fair price from the single source. But

the question for purposes of revisiting the 2000 Decision is simply whether there has

been a material change in circumstances that would alter the analysis, not whether the

conclusion based on that analysis would change. Once a material change has been

established, the impact of the change on the scope of the Buyers’ discretion is relevant to

the merits question concerning their status as managerial employees. The change in

circumstance does not automatically result in a different outcome—it simply warrants a

new look at the previous conclusion.7 Here, the Regional Director’s finding that the

decrease in competitive bidding is a material change in circumstances is within

reasonable bounds. And because the showing necessary to relitigate the Buyers’

managerial status can be met by pointing to “one material differentiating fact,” the Union

       7
         Wolf Creek also finds fault in the Regional Director’s determination that, based
on the material change in circumstances discussed above, “there are material differences
between the [B]uyers’ current job responsibilities and those they had in 2000.” 2017
Decision at 8. The Regional Director continued: “Even though the [B]uyers remain
responsible for preparing and issuing purchase orders as they did in 2000, there has been
a sufficient material change in the manner in which they perform those duties to warrant
reconsideration of their managerial status.” Id.
        To challenge this determination, Wolf Creek cites Goods N’ Fresh Foods, Inc.,
287 N.L.R.B. 1231 (1988), for the proposition that “changes to the manner in which
employees perform their job do not generally warrant reclassification.” Wolf Creek’s Br.
at 28. Wolf Creek’s reliance on Goods N’ Fresh Foods is misplaced. There, the court
considered whether a successor employer inherits the bargaining obligations of the
predecessor employer. Goods N’ Fresh Foods, 287 N.L.R.B. at 1234–35. Nothing in the
decision stands for the proposition that the NLRB cannot reconsider managerial status
where employees go from performing a task in a manner that gives them wide discretion
to performing that task in a manner that gives them little to no discretion.

                                            21
has met its burden. 2017 Remand Order at 3 n.7 (noting that the burden is not “an

onerous one”).

          c. The Buyers’ diminished role in evaluating RFQs

       The Buyers’ diminished role in evaluating responses to RFQs also reflects a

material decrease in the quantity and quality of the Buyers’ exercise of discretion. In all

but “routine or [low]-cost purchases,” the Buyers now “customarily consult with the

requisitioning department, the procurement engineering department, or a manager to

identify a preferred supplier, rather than independently selecting the supplier.” 2017

Decision at 8. When making those decisions, the Buyers are “guided by [Wolf Creek’s]

detailed procedures and nearly always select either the lowest bidder or the supplier who

can provide the materials within the requisitioning department’s timeline.” Id. at 9. This

shows not only a decrease in the frequency with which the Buyers exercise discretion in

selecting vendors, but also implicates the quality of the discretion—if any—that is

exercised when selecting vendors for routine or low-cost purchases.

       As with the decrease in competitive bidding, the diminished role in evaluating

RFQs implicates the Regional Director’s reliance on “[t]he Buyers exercise [of]

independent discretion when they locate vendors without reliance upon pre-approved

lists” and “select a vendor without supervisory approval.” 2000 Decision at 23. Thus,

these changes in circumstances “would materially alter the analysis of the [B]uyers’

managerial status” and are “sufficient to allow reconsideration” of that status. 2017

Remand Order at 3.

                               *              *             *

                                             22
       Whether considered separately or in tandem, the changes in circumstances

authorized reconsideration of the Act’s application to the Buyers. The decrease in

competitive bidding, which Wolf Creek acknowledges occurred, is “one material

differentiating fact,” and the Buyers’ diminished role in evaluating RFQs is another.

Together, these changes in circumstances clearly freed the Regional Director from the

preclusive effect of the 2000 decision.

       In summary, the Regional Director’s factual findings as to a material change in

circumstances were “supported by substantial evidence in the record as a whole” and the

legal determinations are “within reasonable bounds.” Greater Kan. City Roofing, 2 F.3d

at 1051. We therefore proceed to consider the Regional Director’s determination that the

Buyers are not managerial employees.

                                 E. Managerial Status

       As the Board recognized, the question at issue here is “whether the [B]uyers meet

the legal definition of managerial employees”— an “ultimate fact” that must be

determined by applying “governing law to a set of evidentiary facts.” 2017 Remand

Order at 3. So, we begin our analysis by setting out the standard of review applicable to a

managerial status determination. We follow with a description of the Regional Director’s

decision and rationale. Next, we address Wolf Creek’s specific challenges to the Regional

Director’s underlying factual determinations. Finally, we consider the Regional

Director’s ultimate finding that the Buyers were not managerial employees.

                                            23
   Standard of Review

       The scope and applicability of the managerial employee exclusion presents a

mixed question of law and fact. See Yeshiva Univ., 444 U.S. at 691. When applying the

proper legal standard, however, the managerial status inquiry rests on a factual analysis

of “the employees’ actual job responsibilities, authority, and relationship to

management.” See Bell Aerospace, 416 U.S. at 290 & n.19; see also 2017 Remand Order

at 3 (stating question at issue “is an ultimate fact, gleaned by application of governing

law to a set of evidentiary facts: whether the [B]uyers meet the legal definition of

managerial employees”).

       The “difficult problems” intrinsic in determining whether an individual is an

“employee” under the Act “are precisely ‘of a kind most wisely entrusted initially to the

agency charged with the day-to-day administration of the Act as a whole.’” Local No.

207, Int’l Ass’n of Bridge, Structural & Ornamental Iron Workers Union v. Perko, 373
U.S. 701, 706 (1963) (quoting Marine Eng’rs Beneficial Ass’n v. Interlake Steamship

Co., 370 U.S. 173, 180 (1962)). As a result, “[i]n construing the scope of the Act’s

coverage, we must accord great respect for the expertise of the Board ‘when its

conclusions are rationally based on articulated facts and consistent with the Act.’”

Loretto Heights Coll. v. NLRB, 742 F.2d 1245, 1255 (10th Cir. 1984) (quoting Yeshiva

Univ., 444 U.S. at 691). However, “administrators and reviewing courts must take care to

assure that exemptions from [the Act’s] coverage are not so expansively interpreted as to

deny protection to workers the Act was designed to reach.” Holly Farms Corp. v. NLRB,

517 U.S. 392, 399 (1996).

                                             24
       The party asserting the managerial employee exclusion bears the burden of

proving it applies. Cf. NLRB v. Ky. River Cmty. Care, Inc., 532 U.S. 706, 710–11 (2001)

(reaching same conclusion for supervisory employees). Thus, the inquiry here is whether

the Regional Director’s determination that Wolf Creek did not meet its burden of proving

the Buyers are managerial employees is supported by substantial evidence.

   Regional Director’s Decision

       In 2016, the Regional Director concluded “the Buyers do have some discretion,

but their purchasing decisions are dictated by [Wolf Creek’s] policies and procedures.”

2016 Decision at 9. In finding an absence of discretion, the Regional Director focused on

three factual determinations. First, the Regional Director found, “[t]he Buyers rely

heavily on past practice to determine which suppliers they should offer RFQ[]s and, if

they deviate from past practice, Buyers must provide a justification for such a departure.”

2016 Decision at 10. Thus, while the Buyers exercise discretion when selecting the

supplier, such discretion “takes place within the confines of Employer policy.” Id.

       Second, the Regional Director focused on the Buyers’ lack of discretion in

competitively bidding and issuing purchase orders. Although the “Buyers are not required

to competitively bid pre-approved requisitions” under $50,000, they must work within

Wolf Creek’s policies and procedures when making those purchases. Id. Therefore, the

“requisition process effectively sets the limits of Buyer discretion.” Id. And the Buyers

are required to receive additional approval from the requestor if purchases will exceed the

approved requisition price by $1,000 per line item. Thus, “the Buyers can exercise this

discretion, but only within [Wolf Creek’s] pre-established limits.” Id.

                                            25
       Third, the Regional Director considered arguments regarding the amount of

money the Buyers commit and save each year. Although the Buyers committed around

$21 million of Wolf Creek’s funds and saved Wolf Creek over $300,000, the Regional

Director found the Buyers did so while “acting within the scope of the official purchasing

policies and procedures.” Id. at 11.8

       In the 2017 Decision, the Regional Director reaffirmed the prior conclusion that

the Buyers were not managerial employees:

       I find that the [B]uyers’ authority has been circumscribed by [Wolf
       Creek’s] evolving practices and requisition and procurement policies,
       which have been integrated into the EMPAC software to an extent that
       eliminates much of the [B]uyers’ independent discretion. [The] Buyers now
       only infrequently locate and select venders without first consulting a

       8
         In the 2016 Decision, the Regional Director engaged in a separate analysis for
whether the Buyers engaged in significant discretion and whether their interests aligned
with management. The Regional Director concluded the Buyers were not aligned with
management because (1) the Buyers are allowed to purchase an item only after a manager
or supervisor with purchasing authority has requisitioned the item, (2) the Buyers did not
attend any high level management meetings, and (3) the Buyers did not have input into
the changes made to purchasing policies.
        Some NLRB cases have considered discretion and alignment of interest to be part
of the same analysis. See, e.g., Lockheed-California Co., 217 N.L.R.B. 573, 575 (1975)
(concluding the buyers “do not exercise sufficient independent discretion in their jobs to
truly align them with management”). But other decisions have separately considered
whether an employee “is ‘so closely aligned with management as to place the employee
in a position of potential conflict in interest between his employer and his fellow
workers.’” Iowa S. Utils. Co., 207 N.L.R.B. 341, 345 (1973) (quoting Ill. State Journal-
Register, Inc. v. NLRB, 412 F.2d 37, 41 (7th Cir. 1969)).
        Wolf Creek’s only argument regarding alignment of interests appears on the final
page of its brief, where it cites Concepts & Designs, Inc., 318 N.L.R.B. 948 (1995), enf’d
101 F.3d 1243 (8th Cir. 1996), and contends the Union failed to come close to satisfying
its burden on that issue. Wolf Creek’s argument, however, is not based on a potential
conflict of interest between Wolf Creek and the Buyers’ fellow workers. As Wolf Creek
bears the burden of proving the Buyers are managerial employees and, as discussed in
footnote 7 below, Concepts & Designs is not a binding case, we do not consider
alignment with management as a separate issue.

                                           26
       manager or members of the department responsible for a requisition. And,
       although in some circumstances [the B]uyers continue to make vendor
       decisions on routine and cheap purchases, they do so guided by [Wolf
       Creek’s] detailed procedures and nearly always select either the lowest
       bidder or the supplier who can provide the materials within the
       requisitioning department’s timeline. [The] Buyers no longer perform
       technical bid evaluations, add new suppliers without authorization,
       independently decide which suppliers to utilize for engineered or safety-
       related materials, or negotiate prices for goods and services. Moreover, [the
       B]uyers are now more frequently limited to obtaining materials from a
       single source, either because they are constrained by [Wolf Creek’s]
       association agreements, or because the choice of supplier is dictated by
       [Wolf Creek’s] engineering requirements.

       . . . . [The B]uyers have little if any independent purchasing authority, and
       they often rely on others within [Wolf Creek’s] organization to determine
       which supplier to use. Although [the B]uyers still act as [Wolf Creek’s]
       agent[s] to commit [Wolf Creek’s] funds by issuing purchase orders, they
       neither make the ultimate decision to acquire materials or approve the
       acquisition of materials.

2017 Decision at 9–10 (citation omitted). Based on these findings, the Regional Director

reached his ultimate conclusion: The “Buyers operate within the confines of detailed

policies, and they do not exercise the type of discretion indicative of managerial status”

and are therefore “entitled to the protection of the Act.” Id. at 10.

   Specific Substantial Evidence Challenges

       Wolf Creek challenges four of the Regional Director’s underlying factual findings,

or it makes assertions that are directly contrary to those findings. Before addressing the

Regional Director’s ultimate factual conclusion—the Buyers were nonmanagerial

employees—we address Wolf Creek’s challenges to the underlying facts found by the

Regional Director.

                                              27
       To begin, Wolf Creek mounts two challenges to the Regional Director’s

determination that the Buyers “neither make the ultimate decision to acquire materials

[n]or approve the acquisition of materials.” 2017 Decision at 10. First, Wolf Creek

alleges that for the last eighteen years the Buyers have “made the ultimate decision

concerning the acquisition of materials.” Wolf Creek’s Br. at 51. Second, it argues that

the “Buyers remain responsible for committing funds in the company’s best interest.” Id.

at 54. We reject both arguments because the Regional Director’s finding refers to

decisions made by others that limit the Buyers’ involvement. The Buyers initiate

purchases only in response to requisitions filed by someone else. The requisitions reflect

(1) the decision to acquire materials, (2) the supervisory approval of such acquisition, and

(3) the price ceiling for the purchase. Thus, there is substantial evidence in the record to

support a finding that the Buyers are not responsible for these decisions.

       The Regional Director also determined the “[B]uyers have little if any independent

purchasing authority, and they often rely on others within [Wolf Creek’s] organization to

determine which suppliers to use.” 2017 Decision at 10. Wolf Creek attacks this finding

by arguing the Buyers issue purchase orders, issue RFQs, and use their independent

judgment to select suppliers. As discussed at length above, however, there is substantial

evidence in the record to support the Regional Director’s finding that the Buyers

routinely consult with others in the company to select a supplier from competitive bids.

See supra Part I.C.2.c. And it is undisputed that the Buyers’ purchasing authority exists

only when a requisition has been submitted by a supervisor with the appropriate level of

                                             28
authority, and that the requestor’s authority sets the ceiling of the Buyers’ authority.

Substantial evidence, therefore, supports the Regional Director’s finding.

       Next, Wolf Creek asserts the Buyers were involved in the decision to increase the

minimum requirement for competitive bidding from $5,000 to $50,000. Contrary to Wolf

Creek’s assertion, however, the Regional Director concluded the Buyers were not

consulted about this decision. Wolf Creek does not contend the Regional Director’s

finding presents a substantial evidence problem, but rather simply ignores the finding and

points to evidence in the record that could support a contrary finding. It is true the

testimony is inconsistent on this point, but we cannot “displace the Board’s choice

between two fairly conflicting views,” Universal Camera, 340 U.S. at 488. Despite the

conflicting testimony, there is substantial evidence for the Regional Director’s finding.

       Finally, Wolf Creek claims “the Buyers negotiate the final purchase price for

goods and services.” Wolf Creek Br. at 55. Again, Wolf Creek does not assert this as a

substantial evidence challenge but instead, advances it despite the Regional Director’s

contrary finding that the Buyers do not “negotiate prices for goods and services.” 2017

Decision at 9. To be sure, there was conflicting evidence on this point. One Buyer

testified that the Buyers “try to save the company money” by “negotiating with the

suppliers.” Tr. at 161. But when a different Buyer was asked whether the Buyers

negotiate prices with suppliers, the Buyer responded, “No, not really. We just basically

go out and get different bids to get a better price. We don’t go back and say, how about

X-amount instead of this, or whatever. That doesn’t really happen.” Id. at 167. The

Buyers’ supervisor corroborated that point of view when he testified that negotiation in

                                             29
the competitive bidding process is “minimal.” Id. at 206. The supervisor also testified that

Buyers have “negotiated savings” in two circumstances. Id. at 207. The first is when the

Buyer achieves “cost avoidances” by, for example, finding a better deal on freight

charges. Id. The second is “when you have your single sole sources. When you find other

opportunities based on the bid that you’[v]e got that you can get favorable pricing from

an individual through negotiations with them.” Id.

       It is unclear from the context of the supervisor’s testimony exactly when or how

the Buyers will negotiate with single source suppliers. It is, however, apparent from the

record that the Buyers do not negotiate the alliance agreements that select the single

source suppliers. Nor do the Buyers independently reevaluate the pricing in those

agreements to determine whether the goods or services could be procured at lower prices.

       Although Wolf Creek can point to some evidence supporting its claim that the

Buyers exercise discretion in negotiating the purchase price for goods and services, the

Regional Director was not required to credit that evidence over the substantial contrary

evidence. And because Wolf Creek bears the burden of proving the Buyers fall within the

managerial employee exclusion, cf. Ky. River Cmty. Care, 532 U.S. at 711, it follows that

Wolf Creek also bears the burden of placing evidence in the record to prove the Buyers

were exercising discretion by negotiating the purchase price for goods and services. The

Regional Director’s finding that Wolf Creek failed to introduce sufficient evidence to

                                            30
prove the Buyers were negotiating the purchase prices of goods and services is supported

by substantial evidence in the record as a whole.9

   Buyers’ Managerial Status

       In challenging the Regional Director’s ultimate finding, Wolf Creek proceeds

almost exclusively by comparing the facts here to those in previous Board decisions on

the managerial status of employees with purchasing authority. The Board treats prior

published opinions as binding precedent when the factual differences are “of no

substantive importance.” El Conquistador Hotel, Inc., 186 N.L.R.B. 123, 126 (1970); see

also In re Sw. Reg’l Council of Carpenters, 354 N.L.R.B. 930, 932 n.3 (2009)

(recognizing that when a prior Board decision reached a conclusion on “facts very similar

to those presented in this case,” it “is controlling precedent for resolving this case”).10 As

       9
          In asserting that the Buyers do negotiate the purchase prices, Wolf Creek also
cites to transcript pages 326–27 and Wolf Creek’s Procurement Policy section 6.2.
Neither citation supports this proposition. The transcript citation discusses alliance
agreements, which the Buyers are not responsible for negotiating. And Wolf Creek’s
Procurement Policy section 6.2 says nothing about Buyers negotiating prices.

         Notably, two cases are heavily discussed by the parties that are not binding
precedent of the Board and are therefore absent from our analysis. The first is Concepts
& Designs, 318 N.L.R.B. 948. Wolf Creek devotes five pages of its brief arguing the
Regional Director’s managerial status decision should be rejected because Concepts &
Designs “is controlling and the Regional Director failed to correctly apply it to the facts
in this matter.” Wolf Creek’s Br. at 44. In denying review of the 2017 Decision, the
Board explained that Wolf Creek’s reliance on Concepts & Designs was inappropriate
because “the Board did not pass on the issue of managerial status” in that case. 2017
Denial Order at n.1. The employer in Concepts & Designs had prevailed on the
managerial status issue before the Administrative Law Judge, and the employer was the
only party to file exceptions to that decision. 318 N.L.R.B. at 948, 956–57. It is “the
Board’s settled practice” to limit review of a judge’s decision to the issues raised by
exceptions, even where the Board “do[es] not necessarily agree with the judge’s
discussion” of other issues. FES & Plumbers & Pipefitters Local 520 of United Ass’n,

                                              31
a result, we begin by addressing whether prior Board decisions mandate the conclusion

that the Buyers are managerial employees. We then discuss the substantial evidence in

the record supporting the Regional Director’s finding that the Buyers are not managerial

employees.

       a. Prior Board decisions

       When concluding the Buyers were nonmanagerial employees, the Regional

Director relied on two of the Board’s prior decisions, Washington Post Co., 254 N.L.R.B.
168 (1981), and Lockheed-California Co., 217 N.L.R.B. 573 (1975). Wolf Creek takes

three general exceptions to the Regional Director’s reliance on those decisions in its

analysis. First, Wolf Creek argues the Regional Director failed to properly apply other

cases where an employee with discretionary purchasing power was considered a

managerial employee. Second, Wolf Creek claims Washington Post is inapposite and

cannot support a finding that the Buyers were managerial employees. Finally, Wolf Creek

contends the Regional Director was incorrect in concluding that “in nearly all aspects, the

333 N.L.R.B. 66, 66 n.1 (2001). Because the Board did not consider the managerial status
of the employees in Concepts & Designs, the case is not binding on the managerial status
issue.
        Second, Wolf Creek attempts to distinguish Solartec, Inc., 352 N.L.R.B. 331
(2008), enf’d at NLRB v. Solartec, Inc., 310 F. App’x 829 (6th Cir. 2009), which was
cited in the 2016 Decision. In the 2017 Denial order, however, the Board emphasized it
was not relying on the Regional Director’s citation to Solartec in deciding to deny review
because it was a two-member decision, and the Supreme Court recently held the Board
cannot act as a two-member panel. New Process Steel, L.P. v. NLRB, 560 U.S. 674, 679
(2010). Therefore, Solartec is also not binding precedent.

                                            32
[B]uyers’ responsibilities appear to mirror the responsibilities of the non[]managerial

buyers in Lockheed.” 2017 Decision at 10. We address each of these arguments in turn.

            i.   Purchasing authority

       Wolf Creek makes much of the fact that the Buyers committed $21 million of

Wolf Creek’s funds in one year and can submit purchase orders for up to $250,000

without additional prior approval. Wolf Creek argues these levels are on par with or

exceed levels held by buyers deemed managerial employees in other Board decisions.

Wolf Creek’s Br. at 55; Wolf Creek’s Reply Br. at 13–14; see also Salinas Newspapers,

Inc., 279 N.L.R.B. 1007, 1008, 1010 (1986) (managerial employee extended over $1

million in credit each year); Simplex Indus., Inc., 243 N.L.R.B. 111, 112 (1979)

(managerial employee individually committed $5.75 million); Fed. Tel. & Radio Co., 120
N.L.R.B. 1652, 1653–54 (1958) (managerial employee could commit $2,500 without

approval); Nat’l Cylinder Gas Co., 115 N.L.R.B. 726, 729 (1956) (managerial employee

could commit up to $2,000); Mack Trucks, Inc., 116 N.L.R.B. 1576, 1578 (1956)

(managerial employees each committed between $800,000 and $6 million per year); Am.

Locomotive Co., 92 N.L.R.B. 115, 116 (1950) (managerial employees collectively

committed $6 million). But see Lockheed, 217 N.L.R.B. at 574–75 & 575 n.10

(nonmanagerial employees could commit $50,000 without additional approval and

purchased a combined $770 million in one year); Wash. Post, 254 N.L.R.B. at 189

(nonmanagerial employee committed up to $50,000 in purchases each month).

       The problem with Wolf Creek’s argument is that the employees in the comparison

cases appear to have either independent authority to make purchases or have no spending

                                            33
cap on filling requisitions, and the cases reveal no policies cabining the employees’

discretion in procurements. See Salinas Newspapers, 279 N.L.R.B. at 1008 (discussing

employee’s almost unfettered discretion); Simplex Indus., 243 N.L.R.B. at 112

(recognizing there were no procurement policies in place and the buyer was able to

“issue[] and execute[] the purchase orders without any approval or review of his

actions”); Fed. Tel. & Radio Co., 120 N.L.R.B. at 1653–54 (providing a cap but no limit

on discretion to purchase items); Nat’l Cylinder Gas Co., 115 N.L.R.B. at 729

(recognizing employee’s discretion in filling requisitions); Mack Trucks, 116 N.L.R.B. at

1578 (failing to discuss any limits on purchase price or applicable procurement policies);

Am. Locomotive, 92 N.L.R.B. at 116 (providing no discussion on limits to individual

purchases or discretion). Conversely, Wolf Creek’s Buyers do not have the ability to

requisition an item without oversight. For all practical purposes, the Buyers did not

commit $21 million of Wolf Creek’s funds each year. That amount was committed by the

requestors, who dictate what purchase should be made and set the limits on the purchase

price. While it is true the Buyers do not need additional authority for purchases up to

$250,000, this is the case only if the requisition provided a purchase price of $250,000

and the requestor who submitted it had authority to approve a purchase at that price. In

any other circumstance, the Buyers are required to receive additional approval to exceed

the price authorized in the requisition by more than $1,000 per line item. In reality, the

Buyer’s discretion in committing Wolf Creek’s credit is limited to the $1,000 per line

item the Buyer can deviate from the requisition. In comparison to $21 million per year,

                                             34
this $1,000 of authority is relatively insignificant.11 Cf. Lockheed, 217 N.L.R.B. at 575

n.10 (“[W]hile the ability to commit [$50,000] of an employer’s credit may be highly

significant in the context of a small retail enterprise, it is of far less significance in the

context of the aerospace industry.”). We reject Wolf Creek’s argument that we should

deny the application to enforce the 2018 Decision because the Regional Director failed to

rely on Board precedent.

            ii.   Comparison to Washington Post

       Second, Wolf Creek argues the Regional Director “erred in comparing the . . .

Buyers to other non-managerial employees whose duties and authority are wholly

dissimilar,” such as those in Washington Post. Wolf Creek’s Br. at 49. In Washington

Post, the assistant purchasing manager spent half her time in the stock area determining

what items, such as scotch tape, paper, and preprinted forms, needed to be purchased and

ordering them, authorizing between $25,000 and $50,000 in purchases per month. 254
N.L.R.B. at 189. The employer’s guidelines “assist[ed] the purchasing agents when they

seek to secure items.” Id. Generally, bids were solicited from three vendors, and then,

using “price and quality as guidelines,” “the most appropriate vendor for the Employer”

would be selected. Id. The Board found the assistant purchasing manager was

nonmanagerial because while she was “able to commit the Employer to purchasing stock

       11
         Wolf Creek also argues that the Regional Director failed to take into account the
$300,000 the Buyers saved Wolf Creek. The Regional Director did take this into account,
but he found the savings occurred in the course of following Wolf Creek’s procedures
and did not make the Buyer’s managerial employees.

                                               35
items, [she] must conform to certain Employer guidelines, and, on occasion, must clear

decisions with higher department or company authorities.” Id.

       Wolf Creek argues it is “absurd” to compare the Buyers purchasing goods and

services for a nuclear power facility with the assistant purchasing manager in Washington

Post, who purchased scotch tape and paper. Here, “the Buyers are often purchasing

equipment under onerous specifications needed to ensure the safety of the entire facility.”

Wolf Creek’s Reply Br. at 11.12 We are unpersuaded. The Buyers have little to no

discretion when it comes to technical and safety-related items.13 Recall that the Buyers

are limited to approved vendors for all safety-related items, and the Buyers cannot issue a

purchase order for safety and special scope purchases without final approval by others.

Relatedly, any technical changes to RFQs must be approved by the appropriate

department. And the Buyers consult with the requestor when evaluating purchase options,

except for low cost, routine purchases.

       The Regional Director’s comparison to Washington Post is not so far out of

bounds that we would deny the application for enforcement on that ground.

       12
         In support of this proposition, Wolf Creek cites to transcript pages 399:19–
400:11. Importantly, within that testimony, the Buyer says, “I’m not going to choose out
of those bids who we are going to purchase the fans from. That would be done . . . by the
engineering department . . . .” Tr. at 400:1-4.
       13
         The record reflects that the Buyers do, however, have discretion in deciding
whether to competitively bid items such as toilet paper and nuts and bolts.

                                            36
           iii.   Comparison to Lockheed

       Finally, Wolf Creek argues the Regional Director’s reliance on Lockheed

“constitutes an error at law.” Wolf Creek’s Br. at 49. In Lockheed, the buyers were

responsible for procuring items for their employer—a company engaged in the aerospace

industry—in response to requisitions. 217 N.L.R.B. at 574, 575 n.10. The decision to

procure items could be made only by an authorized individual in the organization; the

buyers did not have such authorization. Id.

       After receiving a requisition, the buyers generated a bid list and selected a supplier

from the responses, although both actions were subject to review. Id. Once a supplier was

selected, the buyer was responsible for negotiating unsettled terms, usually including

price, based on an approved negotiation range. Id. When the terms were fixed, the buyer

was required to receive final authorization before executing a purchase order. Id. at 575.

After the purchase was completed, the buyer remained responsible for coordinating “the

Employer’s relationship with its suppliers and customers,” including “the resolution of

problems which arise in relation to items the [b]uyer has procured.” Id.

       The Board concluded the buyers in Lockheed did not “have discretion in the

performance of their jobs independent of their employer’s established policy.” Id. In

reaching that conclusion, the Board was “not unmindful of all the various activities and

functions of the [b]uyers, particularly their credit committing function” to the tune of

$770 million each year. Id. at 575 & n.10. But the buyers’ activities were “circumscribed

to varying degrees by the Employer’s established policy or by the review power placed in

                                              37
higher authority.” Id. at 575. Therefore, the Board concluded the buyers did “not exercise

sufficient independent discretion in their jobs to truly align them with management.” Id.

       Wolf Creek argues Lockheed is inapposite because those buyers (1) were not

subject to educational requirements; (2) had little discretion in formulating bid lists;

(3) were given a level of authorization based on estimated cost of procurement rather than

the requestor’s purchasing power; (4) were subject to greater scrutiny when selecting

winning bidders; and (5) “could not be further from” the Buyers in this case because the

Buyers “alone are responsible for resolving issues, including negotiating price and

delivery disputes.”14 Wolf Creek’s Br. at 45–47.

       Wolf Creek fails to explain the significance of the educational requirements or

how the level of purchasing power is determined. While there are some differences

between the procurement process used by Lockheed and that used by Wolf Creek,

including whether limitations on discretion were imposed by supervisor review or by

employer policy, those differences are not so substantial as to compel rejection of the

Regional Director’s conclusion. And the distinctions between the Buyers here and the

employees in Lockheed and Washington Post are no more material than the differences

       14
         This fifth argument is an inaccurate characterization of the buyers’
responsibilities in Lockheed. The Board explicitly determined the buyers were
responsible for negotiating unsettled terms and conditions, including price, and for
“coordinat[ing] the Employer’s relationship with its suppliers and customers,” including
“the resolution of problems which arise in relation to items the Buyer had procured.”
Lockheed, 217 N.L.R.B. at 574–75. Additionally, as discussed above, there is substantial
evidence to support the Regional Director’s conclusion in this case that the Buyers are
not responsible for negotiating the final price.

                                             38
between the Buyers and the managerial employees in the cases advanced by Wolf Creek.

In summary, prior Board decisions do not provide any basis for refusing to enforce the

2018 Decision.

       b. General substantial evidence for nonmanagerial status

       The Regional Director ultimately concluded the Buyers were nonmanagerial

employees because they “operate within the confines of detailed policies, and they do not

exercise the type of discretion indicative of managerial status.” 2017 Decision at 10.

There is substantial evidence in the record to support that finding.

       From the initiation of the procurement process forward, the Buyers’ discretion is

cabined by Wolf Creek’s policies. As discussed, the requestors, not the Buyers, determine

what items to purchase and the amount to be spent—within $1,000 per line item. And no

matter what, the Buyers’ spending authority is limited to $250,000, absent special

authorization.

       Although Buyers are generally required to competitively bid purchases expected to

exceed $50,000, various circumstances have reduced competitive bidding to 10% of

purchases. This is true even though the Buyers have the discretion to competitively bid

purchases below the $50,000 threshold. For example, Wolf Creek’s policy does not

require competitive bidding when there are alliance agreements in force, there are

“[f]ewer than three qualified suppliers,” during plant emergencies, or when there is an

“[e]stablished supplier that has previously demonstrated a competitive cost.” Employer’s

Ex. 1 at p. 3, no. 6.1. Competitive bidding is further limited due to the age of the plant

and the specialized nature of some materials needed. In addition, all safety-related

                                             39
purchases must be made from an approved supplier and there is often only one approved

supplier, obviating the need for competitive bidding.

       If a purchase is competitively bid, the Buyer has the discretion to create the list of

places to send RFQs, except for safety-related items, which are limited to approved

suppliers. By policy, the Buyers determine which suppliers to send RFQs “based on

commercial, technical, and/or quality considerations” and “should consider source

recommendations offered” by the requestor. Employer’s Ex. 1 at p. 4, no. 6.3. If a

supplier requests an exception to the RFQ that consists of any technical changes to

equipment, the Buyer is required to receive approval for the alteration. Under Wolf

Creek’s policy, the Buyer must communicate all exceptions or clarifications “to the

appropriate organization/department for resolution.” Employer’s Ex. 1 at p. 4, no. 6.5.1.

       Once the Buyer receives bids, the Buyer will perform a commercial evaluation to

“determine the best cost, best delivery of the requested product.” Tr. at 184. Generally,

however, for routine or low-cost items the Buyer will simply select the lowest bid. But

the Buyer may select a slightly more expensive bid depending on delivery timeframes.15

Conversely, when there are technical purchases, it is up to the requesting department to

evaluate the technical requirements, the quality, the price, and the timeframe to determine

which bid to accept. And if the Buyer is not making a routine or low-cost purchase, the

Buyer will “consult the requestor” when deciding who won the bid. Tr. at 329.

       15
         In making this decision, the Buyer will still often consult with his or her
supervisor or the requestor.

                                             40
       Regardless of whether a purchase was competitively bid, the Buyers are generally

not authorized to submit a purchase order for an item for an amount greater than $1,000

per line item above the amount approved in the requisition. The Buyers are also not

allowed to submit a purchase order for “safety related and special scope purchases”

without review and approval from Procurement Quality. Employer’s Ex. 2 at p.7, no.

6.2.5. And the Buyers’ supervisor can cancel any purchase order after it is issued. Once a

purchase order issues, the Buyers are responsible for arranging shipping and have some

discretion in selecting a shipping service. But that discretion has been somewhat limited

by price negotiations through alliance agreements. Additionally, the Buyers will handle

some disputes with suppliers after the purchase has been completed.

       The Supreme Court has emphasized that employees are managerial if they

exercise discretion in performing their job, but not “if th[at] discretion must conform to

an employer’s established policy.” Bell Aerospace, 416 U.S. at 288 n.16 (quoting Retail

Clerks Int’l Ass’n, 366 F.2d at 645). The Regional Director considered all the evidence

and found that, “in nearly all aspects of their jobs, [the B]uyers ‘act[] within prescribed

limits under policies determined by company officials and only with clearance or

approval by superior authority.’” 2017 Decision at 10 (quoting Iowa S. Utils. Co., 207
N.L.R.B. 341, 345 (1973)). There is substantial evidence in the record supporting the

Regional Director’s conclusion that the Buyers are operating within the confines of

detailed policies. As one Buyer testified, “[t]he culture, [has] become a lot stricter. . . .

[Y]ou hear the term, literal compliance, literal compliance to procedures almost daily. I

mean, . . . you know, do it to the letter of the law.” Tr. at 156. The Regional Director’s

                                               41
conclusion that Wolf Creek failed to prove the Buyers are managerial employees is

“rationally based on articulated facts and consistent with the Act,” Yeshiva Univ., 444
U.S. at 691, so “we must accord great respect to the expertise of the Board,” Loretto

Heights Coll., 742 F.2d at 1255.

       We reject Wolf Creek’s challenges and therefore conclude the Board is entitled to

enforcement of the 2018 Decision. See 29 U.S.C. § 160(e).

                                   III.   CONCLUSION

       The Board “correctly interpreted and applied the law” and “its factual findings are

supported by substantial evidence in the record as a whole.” Greater Kan. City Roofing, 2
F.3d at 1051. We GRANT the Board’s application for enforcement of the 2018 Decision.
