                          SUMMARY **

        Diversity / Employee Wage and Hour Laws

    The panel affirmed the district court’s judgment on the
pleadings in favor of Defendants Amazon.com Services, Inc.
and Amazon.com, Inc., in a class action alleging that
Defendants’ failure to compensate employees for time spent
waiting for and passing through mandatory security
screenings before and after work shifts and off-premises
meal breaks violated Oregon’s wage and hour laws.
    The panel had certified the following issue to the Oregon
Supreme Court: “Under Oregon law, is time that employees
spend on the employer’s premises waiting for and
undergoing        mandatory          security       screenings
compensable?” In response, the Oregon Supreme Court
held that Oregon law aligns with federal law regarding what
activities are compensable. Therefore, time that employees
spend on the employer’s premises waiting for and
undergoing mandatory security screenings before or after

their work shifts is compensable only if the screenings are
either (1) an integral and indispensable part of the
employees’ principal activities, or (2) compensable as a
matter of contract, custom, or practice.
    Plaintiff’s complaint did not allege that either of the
identified exceptions applied. Accordingly, the panel held
that the district court properly granted judgment on the
pleadings to Defendants. Although the Oregon Supreme
Court’s opinion did not address separately or directly
Plaintiff’s meal-period claim, the logic of that opinion
yielded the same result. Under both federal and state law,
the test is whether an employee performed work duties
during the meal period. And under both Oregon and federal
regulations, employees on meal breaks must be relieved
from duty. Because the Oregon Supreme Court squarely
held that Oregon law aligns with federal law regarding what
activities are compensable and because Plaintiff failed to
allege that undergoing a mandatory security screening was
“an integral and indispensable part” of an employee’s
principal activities, her claim failed.

                        OPINION

PER CURIAM:

    Plaintiff Lindsey Buero filed a class action against
Defendants Amazon.com Services, Inc. and Amazon.com,
Inc., alleging that Defendants’ failure to compensate
employees for time spent waiting for and passing through
mandatory security screening before and after work shifts
and breaks violates Oregon’s wage and hour laws. The
district court granted judgment on the pleadings to
Defendants, and Plaintiff timely appealed to us. Because
there was no controlling Oregon precedent on that important
and dispositive question of state law, we certified the issue
to the Oregon Supreme Court: “Under Oregon law, is time
that employees spend on the employer’s premises waiting
for and undergoing mandatory security screenings
compensable?” Buero v. Amazon.com Servs., Inc., 370 Or.
502, 504, 521 P.3d 471, 473 (2022) (en banc).
    The Oregon Supreme Court answered that question in
the negative:

       Oregon law aligns with federal law regarding
       what activities are compensable. Therefore,
       under Oregon law, as under federal law, time
       that employees spend on the employer’s
       premises waiting for and undergoing
       mandatory security screenings before or after
       their work shifts is compensable only if the
       screenings are either (1) an integral and
       indispensable part of the employees’
       principal activities or (2) compensable as a
       matter of contract, custom, or practice.

Id. at 504, 521 P.3d at 473. 1 Plaintiff’s complaint does not
allege that either of the identified exceptions applies.
Accordingly, on de novo review, S.F. Apartment Ass’n v.
City & County of San Francisco, 881 F.3d 1169, 1175 (9th
Cir. 2018), we now hold that the district court properly
granted judgment on the pleadings to Defendants.
    Although the Oregon Supreme Court’s opinion did not
address separately or directly Plaintiff’s meal-period claim,
the logic of that opinion yields the same result. In addition
to requiring security screening when employees arrive at
work and leave work, Defendants require employees to
undergo security screening if they choose to leave the
premises during meal periods and also choose to take
belongings with them. Under Oregon law, employees must
be “relieved of all duties” during meal breaks. Or. Admin.
R. 839-020-0050(2)(a)–(b). That regulation, like the ones
that the Oregon Supreme Court discussed, “aligns with” the
comparable federal regulation, Buero, 370 Or. at 526–27,
521 P.3d at 485 which requires employees on meal breaks to
be “completely relieved from duty,” 29 C.F.R. § 785.19(a).
Under both federal and state law, the test is whether an
employee performed work duties during the meal period.

(Oregon law). Because the Oregon Supreme Court has
squarely held that Oregon law aligns with federal law
regarding what activities are compensable, Buero, 370 Or. at
504, 521 P.3d at 473, and because Plaintiff fails to allege that

         DUNCAN, J.
         Plaintiff brought a class action against defendants
in state court, alleging, among other things, that defendants
had violated Oregon’s wage laws by failing to pay employees
for time spent in mandatory security screenings at the end of
their work shifts. Defendants removed the case to federal court
and moved for judgment on the pleadings, asserting that the
time spent in the security screenings was not compensable. In
support of that argument, defendants cited Integrity Staffing
Solutions, Inc. v. Busk, a case involving a similar claim against
defendants, in which the United States Supreme Court held
that, under federal law, time spent in the security screenings
at issue in that case was not compensable. 574 US 27, 29, 135
S Ct 513, 190 L Ed 2d 410 (2014). Defendants argued that
Oregon’s wage laws track federal wage laws and, therefore,
time spent in the security screenings at issue in this case was
not compensable under Oregon law.
          The district court agreed with defendants, noting the
similarities between Oregon administrative rules enacted
by the state’s Bureau of Labor and Industries (BOLI) and
federal law. Plaintiff appealed to the Ninth Circuit and filed
a motion asking that court to certify a question to this court
regarding whether time spent in security screenings is com-
pensable under Oregon law. The Ninth Circuit granted the
motion and certified the following question: “Under Oregon
law, is time that employees spend on the employer’s premises
waiting for and undergoing mandatory security screenings
compensable?” This court accepted the certified question.
For the reasons explained below, we conclude that Oregon
law aligns with federal law regarding what activities are
compensable. Therefore, under Oregon law, as under federal
law, time that employees spend on the employer’s premises
waiting for and undergoing mandatory security screenings
before or after their work shifts is compensable only if the
screenings are either (1) an integral and indispensable part
of the employees’ principal activities or (2) compensable as a
matter of contract, custom, or practice.
                     I. BACKGROUND
         The relevant facts are few. In 2018, plaintiff worked
for defendants in a warehouse in Troutdale. In the warehouse,
Cite as 370 Or 502 (2022)                                 505

there was a secured area where merchandise was located.
Before entering the secured area, employees could store
their personal items in lockers.
         When employees left the secured area at the end of
their work shifts, they would clock out and then undergo a
security screening that defendants used to prevent theft of
merchandise from the secured area. There were nine screen-
ing lanes. If an employee had not brought any metal items
or bags into the secured area at the start of their shift, the
employee could leave using one of five “express lanes,” in
which they would simply walk through a metal detector. If
an employee had brought metal items but no bags into the
secured area, the employee could use one of two “disburse-
ment lanes,” in which they would walk through a metal
detector and slide their metal items down sloped ramps
next to the detector. If an employee had brought a bag into
the secured area, the employee had to use one of two lanes,
in which they would walk through a metal detector and
put their bag on a conveyor belt for x-ray screening. If an
employee set off a metal detector in any of the lanes, a secu-
rity guard with a handheld metal detector would check the
employee’s person for merchandise.
         After passing through the screening, employees could
remain in the warehouse for a variety of reasons, including
to use the lockers, a breakroom, and phones and computers
provided by defendants. To leave the warehouse, employees
would swipe their badges and pass through turnstiles at the
exits.
                       II. ANALYSIS
          The security screenings at issue in this case are
similar to the screenings at issue in Integrity Staffing. As
mentioned, in that case, the Supreme Court held that time
spent in the screenings was not compensable under federal
law. Integrity Staffing, 574 US at 29. Because the question in
this case requires us to determine whether Oregon law mir-
rors federal law, we begin with a review of the evolution of
federal and state wage laws, looking first at federal law (spe-
cifically, the Fair Labor Standards Act (FLSA), as modified
by the Portal-to-Portal Act and as construed by Supreme
Court case law) and then to Oregon’s wage statutes and
506                     Buero v. Amazon.com Services, Inc.

administrative rules (specifically, ORS 653.010(11), which
concerns “work time,” and administrative rules that define
“hours worked,” OAR 839-020-0004 and OAR 839-020-0040
through 839-020-0046).
A. Relevant Law
      1. Federal law: The FLSA and the Portal-to-Portal Act
        Congress enacted the FLSA in 1938. Pub L 75-718,
52 Stat 1060 (1938) (codified as amended at 29 USC §§ 201-
219). The FLSA established the first federal minimum wage
and required employers to pay overtime wages for employ-
ment beyond the statutorily set workweek. Id. §§ 6-7, 52 Stat
at 1062-63.
         Although the FLSA set wage requirements, the
FLSA did not specify what types of activities were compen-
sable. Shortly after the enactment of the FLSA, questions
regarding what activities were compensable came before
the Supreme Court. In Tennessee Coal Co. v. Muscoda Local,
iron-ore miners argued that time they spent traveling
underground in the mines to and from their work site had
to be compensated as “work” time. 321 US 590, 592, 64 S Ct
698, 88 L Ed 949 (1944). The Court agreed. Id. at 603. The
Court explained that “work” means “physical or mental
exertion (whether burdensome or not) controlled or required
by the employer and pursued necessarily and primarily for
the benefit of the employer and his business.” Id. at 598.
Then, in Anderson v. Mt. Clemens Pottery Co., plant workers
argued, among other things, that time they spent walking
from the timeclock to their work site within their employer’s
eight-acre plant was compensable. 328 US 680, 682-84, 66
S Ct 1187, 90 L Ed 1515 (1946). The Court agreed, holding that
“hours worked” “includes all time during which an employee
is necessarily required to be on the employer’s premises, on
duty or at a prescribed workplace.” Id. at 690-91. Thus, in
Tennessee Coal and Anderson, the Court construed “work”
and “hours worked” broadly to cover activities in addition to
the principal activities for which an employee is employed.
Specifically, the Court construed those terms to include time
employees spent traveling on their employers’ premises to
and from the location of their principal work activities.
Cite as 370 Or 502 (2022)                                      507

         The year after Anderson, Congress responded to
the Supreme Court’s broad reading of the FLSA by pass-
ing the Portal-to-Portal Act of 1947. Pub L 80-49, 61 Stat
84 (codified as amended at 29 USC §§ 251-262). In a state-
ment of facts accompanying the act, Congress stated that
the FLSA “has been interpreted judicially in disregard of
long-established customs, practices, and contracts between
employers and employees,” and that interpretation had cre-
ated “wholly unexpected liabilities, immense in amount and
retroactive in operation, upon employers” that would have a
wide range of serious adverse consequences on employers,
employees, the courts, the government, and the economy as
a whole. Id. § 1(a), 61 Stat at 84.
         To limit those consequences, the Portal-to-Portal
Act provided employers with relief from existing claims
and exempted them from future claims for compensation
for certain activities, including, but not limited to, the
activities that had been at issue in Tennessee Coal and
Anderson. Section 4 of the Portal-to-Portal Act provides, in
part:
     “(a) Except as provided in subsection (b), no employer
  shall be subject to any liability or punishment under the
  Fair Labor Standards Act of 1938, as amended, * * * on
  account of the failure of such employer to pay an employee
  minimum wages, or to pay an employee overtime compen-
  sation, for or on account of any of the following activities of
  such employee * * *[:]
     “(1) walking, riding, or traveling to and from the actual
  place of performance of the principal activity or activities
  which such employee is employed to perform[;] and
      “(2) activities which are preliminary to or postlim-
  inary to said principal activity or activities, which occur
  either prior to the time on any particular workday at which
  such employee commences, or subsequent to the time on
  any particular workday at which he ceases, such principal
  activity or activities.
      “(b) Notwithstanding the provisions of subsection (a)
  which relieve an employer from liability and punishment
  with respect to an activity, the employer shall not be so
  relieved if such activity is compensable by either[:]
508                            Buero v. Amazon.com Services, Inc.

       “(1) an express provision of a written or nonwritten
   contract in effect, at the time of such activity, between such
   employee, his agent, or collective-bargaining representa-
   tive and his employer; or

       “(2) a custom or practice in effect, at the time of such
   activity, at the establishment or other place where such
   employee is employed, covering such activity, not inconsis-
   tent with a written or nonwritten contract, in effect at the
   time of such activity, between such employee, his agent, or
   collective-bargaining representative and his employer.”

Id. § 4, 61 Stat at 86-87.1 Thus, unless an exception applies,
an employee cannot hold an employer liable under the FLSA,
as modified by the Portal-to-Portal Act, for failing to pay an
employee either for time the employee spent “walking, rid-
ing, or traveling to and from the actual place of performance
of the principal activity or activities which such employee is
employed to perform” or for time spent in “activities which
are preliminary to or postliminary to said principal activity
or activities,” if those preliminary or postliminary activities
occur either before the employee commences or after the
employee ceases the employee’s principal activity or activi-
ties. Id. § 4(a), 61 Stat at 87.
       In subsequent cases, the Supreme Court interpreted
and applied the Portal-to-Portal Act. In Steiner v. Mitchell,
the Court ruled that
   “activities performed either before or after the regular
   work shift * * * are compensable under the portal-to-portal
   provisions of the Fair Labor Standards Act if those activi-
   ties are an integral and indispensable part of the principal
   activities for which covered workmen are employed and are
   not specifically excluded by Section 4(a)(1) [which governs
   time spent traveling to and from the location of an employ-
   ee’s principal activities].”

350 US 247, 256, 76 S Ct 330, 100 L Ed 267 (1956). Applying
that rule, the Court concluded that changing clothes and
showering were an integral and indispensable part of the

    1
      Section 4 of the Portal-to-Portal Act provided employers with relief from
future claims, while section 2 provided employers with retroactive relief from
existing claims. Portal-to-Portal Act of 1947, § 2, 61 Stat at 85-86.
Cite as 370 Or 502 (2022)                                509

principal activities of battery plant employees whose job
duties required “extensive use of dangerously caustic and
toxic materials.” Id. at 248, 256; see also Mitchell v. King
Packing Co., 350 US 260, 263, 76 S Ct 337, 100 L Ed 282
(1956) (applying the integral and indispensable test and
concluding that knife sharpening was an integral and indis-
pensable part of the principal activities of butchers).
         To summarize, under the FLSA, as modified by
the Portal-to-Portal Act and as subsequently construed by
the Court, time that employees spend engaged in activities
before or after their regular work shifts is not compensable,
unless those activities are (1) an integral and indispensable
part of the employees’ principal activities or (2) compensable
as a matter of contract, custom, or practice. Accordingly, in
Integrity Staffing, the Supreme Court held that time that
employees spent waiting for and undergoing the security
screenings at issue in that case—which the court held was
time spent in “postliminary activities”—was not compensa-
ble because activities were not “integral and indispensable”
to the employees’ principal activities. 574 US at 35.
    2. Oregon law: Statutes and administrative rules
         The question in this case is whether we should
reach the same conclusion under Oregon law as the Supreme
Court reached in Integrity Staffing under federal law. Put
differently, the question is whether Oregon law mirrors fed-
eral law regarding what activities are compensable, which
would lead to the same result in this case as in Integrity
Staffing. To resolve that question, we must examine the rel-
evant state statutes and administrative rules.
        a. Oregon’s Statutes
         In 1965, the Oregon legislature considered House
Bill (HB) 1592, which provided for a $1.25 minimum wage
for each hour of “work time.” HB 1592, § 4(1). It further
provided, “ ‘Work time’ includes both time worked and time
of authorized attendance.” Id. § 2(6). HB 1592 passed the
House but was tabled in committee in the Senate and did not
become law. Senate and House Journal 735 (1965); Minutes,
Senate Committee on State and Federal Affairs, May 14,
1965, 1.
510                     Buero v. Amazon.com Services, Inc.

         In 1966, Congress amended the FLSA. Act of
Sept 23, 1966, Pub L 89-601, 80 Stat 830. The amend-
ment extended the FLSA’s coverage to certain categories
of employees that had previously been excepted from cover-
age, including hospital and nursing home workers and some
agricultural workers. Id. §§ 102(a), 203(a), 80 Stat at 831,
833. It also provided for increases in the federal minimum
wage from $1.25 to $1.60 in steps. Id. § 301(a), 80 Stat at
838.

         One month after the 1966 FLSA amendments went
into effect, the Oregon legislature again considered a min-
imum wage bill, HB 1340 (1967). Like HB 1592, HB 1340
provided for a minimum wage for each hour of “work time”
by employees, and it provided, “ ‘Work time’ includes both
time worked and time of authorized attendance.” HB 1340,
§§ 2(9), 4(1). But HB 1340 applied only to employees who
were not covered by the FLSA. Id. § 3(8).

         The legislature recognized that, after the 1966
amendments to the FLSA, a smaller portion of employees
in the state remained without minimum wage and over-
time protections. Tape Recording, House Floor Debate, HB
1340, Apr 5, 1967, Tape 12, Side 2 (Representative Morris
Crothers’s floor statement discussing the expansion of cov-
erage under the FLSA and explaining that “about the only
people that are left to whom this will apply in the State
of Oregon are people in small retail and service organi-
zations”); see also Tape Recording, House Committee on
Labor and Management, HB 1340, Mar 17, 1967, Tape 22
(Representative John Anunsen asking how many employees
would be covered, and George Brown, who had been involved
in crafting the bill, testifying that more employees had been
“roped in” under the amended federal law than had pre-
viously been included when the legislature discussed HB
1592). HB 1340 provided state protections for some of those
employees.

        The exclusion of employees covered by the FLSA
was significant. In his floor statement given at the bill’s
third reading and its passage by the House, Representative
Crothers highlighted the import of the exemption. Tape

Tape 12, Side 2 (“[M]ore important than [the exemption for
piece work employees in agriculture], * * * an exemption is
given to any person subject to regulation under the federal
Fair Labor Standards Act.”).

         Legislators and witnesses who testified about HB
1340 explained that the bill would not apply to most employ-
ees in the state. As Representative Crothers explained in
his floor statement, “A number of years ago a minimum
wage bill in the State of Oregon would have had a very large
economic impact on the state. It no longer does because the
federal regulations have pretty largely preempted the field.”
Tape Recording, House Floor Debate, HB 1340, Apr 5, 1967,
Tape 12, Side 2. Representative Crothers’s estimated that
“probably not more than 5,000 people in the State of Oregon
would be covered by this minimum wage law.” Id.; see also
id. (Representative Joe Rogers noting that “this is not going
to cover many employees”); id. (Representative Jason Boe
commenting that “these few that are involved * * * are the
citizens of Oregon who stand in most need of this help”).

         Industry witnesses similarly recognized the bill’s
limited scope. One witness pointed out that “by far the vast
amount of Oregon employees are covered by the federal
minimum wage.” Minutes, Senate Committee on Labor and
Industries, Apr 26, 1967, 5 (summarizing testimony of Doug
Heider of the Oregon Retail Council and Associated Oregon
Industries); see also Tape Recording, House Committee on
Labor and Management, HB 1340, Mar 13, 1967, Tape 20
(testimony of B.W. Fullerton of Malheur County Farm Labor
Sponsoring Association, stating that, in Malheur County,
the bill would apply only to a small number of employees).

         In addition, the Commissioner of Labor explained
that many of the employees who were still not covered by
the FLSA’s wage and hour protections mistakenly believed
that they were covered by those federal protections. Tape

HB 1340, Mar 10, 1967, Tape 19. The commissioner also tes-
tified that the bill would provide only “the bare minimum
protection to the wage earner.” Id.

         To summarize, in 1967 the Oregon legislature
passed HB 1340 to provide state protections to a small num-
ber of employees so that they would have similar coverage to
what many of them believed they already had under federal
law.2 Or Laws 1967, ch 596. The bill required compensation
for “work time,” and that requirement is now codified as ORS
653.025. The bill also provided that “ ‘[w]ork time’ includes
both time worked and time of authorized attendance,” and
that provision is now codified as ORS 653.010(11), which is
the statutory provision at issue in this case.3
           b.    BOLI’s Administrative Rules
         More than two decades later, in 1989, the Oregon
legislature increased the state minimum wage above the
federal minimum wage and expanded Oregon’s wage stat-
utes to cover employees already protected by the FLSA so
that they would be entitled to Oregon’s minimum wage. Or
Laws 1989, ch 446, §§ 2, 4. Then, in 1990, BOLI promulgated
administrative rules regarding compensable time. The first
relevant BOLI rule is OAR 839-020-0004 (Rule 4). Rule 4
defines terms for the purposes of Oregon’s wage and hour
statutes and BOLI’s administrative rules. In 1990, BOLI
amended Rule 4 by adding a subsection to define “hours
worked.” As relevant here, Rule 4 provides:
       “As used in ORS 653.010 to 653.261 and these rules,
    unless the context requires otherwise:
        “* * * * *
      “(19) ‘Hours worked’ means all hours for which an
    employee is employed by and required to give to the
    2
      The state protections were not identical to the federal protections. As men-
tioned, the Oregon legislature considered HB 1592 in 1965, and that bill provided
for a state minimum hourly wage of $1.25. HB 1592 § 4(1). The following year,
Congress amended the FLSA to provide for an increase, in steps over time, of the
federal minimum hourly wage from $1.25 to $1.60. Pub L 89-601, § 301(a), 80 Stat
at 838. The next year, the Oregon legislature considered HB 1340, which, like HB
1592, provided for a state minimum hourly wage of $1.25. HB 1340 § 4(1). But,
unlike the amended FLSA, HB 1340 did not provide for future increases in the
minimum wage. See id. In that respect, HB 1340 was less beneficial to employees
than the FLSA.
    3
      The Oregon legislature has amended ORS 653.010 several times since
its enactment in 1967. As definitions have been added, the subsections have
been renumbered, but the substance of the definition of “work time” remains
unchanged. The court quotes from the current version of the statute.
Cite as 370 Or 502 (2022)                                                 513

   employer and includes all time during which an employee
   is necessarily required to be on the employer’s premises,
   on duty or at a prescribed work place and all time the
   employee is suffered or permitted to work. ‘Hours worked’
   includes ‘work time’ as defined in ORS 653.010(11).”
         When BOLI added the “hours worked” definition
to Rule 4, it also promulgated OAR 839-020-0040 through
839-020-0046 (Rules 40 through 46). Those rules are known
collectively as the “Hours Worked series.” 4 Rule 40 sets out
the purpose of the series. It states that the series “deals with
hours worked as defined by [Rule 4] and discusses princi-
ples involved in determining what constitutes working time
for purposes of [Oregon’s wage and hour statutes] ORS
653.010 to 653.261 and these rules.” The remaining rules
in the series govern the compensability of time that employ-
ees spend engaged in certain activities for which compen-
sability might not be straightforward, because it might not
involve the performance of the principal activities for which
the employees are employed—specifically, time spent wait-
ing (Rule 41), time spent sleeping (Rule 42), time spent in
preparatory and concluding activities (Rule 43), time spent
in lectures, meetings, or training programs (Rule 44), travel
time (Rule 45), and time spent on other miscellaneous activ-
ities (Rule 46).
        Of the Hours Worked series, the parties have focused
on Rule 43. Rule 43 provides:
      “(1) Preparatory and concluding activities are con-
   sidered hours worked if the activities performed by the
   employee are an integral and indispensable part of a prin-
   cipal activity for which the employee is employed:
       “(a) Example: A bank teller counts the till and
   arranges the work space in preparation for receiving cus-
   tomers. This activity is an integral and indispensable part
   of the principal activity for which the employee is employed
   and is included as hours worked;
      “(b) Example: In connection with the operation of a
   lathe, the lathe operator oils, greases, or cleans the machine

   4
     OAR 839-020-0047 (Rule 47), which applies the other rules of the Hours
Worked series to agricultural employees, was later added to the series. OAR 839-
020-0047 (July 25, 1990).
514                          Buero v. Amazon.com Services, Inc.

     or installs a new cutting tool. Such activities are an inte-
     gral and indispensable part of a principal activity and are
     included as hours worked;
         “(c) Example: Agricultural workers must dress in pro-
     tective clothing and thoroughly clean up after their work
     with or around pesticides. The time spent in these activi-
     ties is work time.
        “(2) These rules are applicable even where there exists
     a custom, contract or agreement not to pay for the time
     spent in such activity.
        “(3) Where a contract, custom or practice dictates cer-
     tain activities to be considered as work time, even though
     not considered to be an integral and indispensable part of
     a principal activity, the time devoted to such activities will
     be considered as work time.”
Thus, section 1 of Rule 43 provides that preparatory and
concluding activities are compensable if they are “an inte-
gral and indispensable part” of an employee’s principal
activity, and section 3 provides that preparatory and con-
cluding activities are compensable, “even though not consid-
ered to be an integral and indispensable part of a principal
activity,” “[w]here a contract, custom or practice” so dictates.
B.    The Parties’ Arguments
         Having reviewed the evolution of the relevant fed-
eral and state laws, we turn to the parties’ arguments. The
parties offer competing interpretations of BOLI’s admin-
istrative rules and ORS 653.010(11), which defines “work
time.” As mentioned, the district court concluded that the
security screenings at issue were not compensable. In doing
so, the court relied on BOLI’s administrative rules. It under-
stood those rules to track federal law, and it specifically
understood Rule 43 to limit the compensability of prepara-
tory and concluding activities as the federal Portal-to-Portal
Act does. In this court, plaintiff argues that (1) BOLI’s rules
do not limit compensation for preparatory and concluding
activities, but, (2) if they do, they are inconsistent with ORS
653.010(11) and, therefore, are invalid. In response, defen-
dants argue that (1) BOLI’s rules track federal law and limit
compensation for preparatory and concluding activities, and
(2) they are consistent with ORS 653.010(11), which was
Cite as 370 Or 502 (2022)                                                   515

also intended to track federal law. To resolve the parties’
arguments, we first construe BOLI’s rules and then ORS
653.010(11).
C. Construction of BOLI’s Administrative Rules
         As we will explain, the BOLI rules mirror federal
law; they use the same structure and language as federal
law. Taken together, Rule 4 and Rule 43 parallel the FLSA,
as modified by the Portal-to-Portal Act and case law inter-
preting that act. We so conclude based on the rules’ text,
context, and rulemaking history. See Gafur v. Legacy Good
Samaritan Hospital, 344 Or 525, 532-33, 185 P3d 446 (2008).
        1. Text
             Again, Rule 4 provides:
       “As used in ORS 653.010 to 653.261 and these rules,
    unless the context requires otherwise:
          “* * * * *
        “(19) ‘Hours worked’ means all hours for which an
    employee is employed by and required to give to the
    employer and includes all time during which an employee
    is necessarily required to be on the employer’s premises,
    on duty or at a prescribed work place and all time the
    employee is suffered or permitted to work. ‘Hours worked’
    includes ‘work time’ as defined in ORS 653.010(11).”5
Rule 4 defines “hours worked” broadly; it is similar to the
Supreme Court’s interpretation of “hours worked” in its pre-
Portal-to-Portal Act cases, Tennessee Coal and Anderson. In
fact, Rule 4 uses the same language as Anderson, in which
    5
        As initially promulgated, Rule 4’s definition provided:
    “ ‘Hours worked’ means all hours for which an employee is employed by and
    required to give to his/her employer and includes all time during which an
    employee is necessarily required to be on the employer’s premises, on duty or
    at a prescribed work place and all time the employee is suffered or permitted
    to work.”
OAR 839020-0004(13) (Feb 27, 1990). Although Rule 4’s definition of “hours
worked” did not initially refer to “work time,” BOLI amended the rule five months
later by adding the following sentence at the end: “ ‘Hours worked’ includes ‘work
time’ as defined in ORS 653.010(1[1]).” OAR 839 020-0004(14) (July 25, 1990). We
do not understand that additional sentence to indicate a different rulemaking
intent or change the meaning of “hours worked.” Indeed, “hours worked” as we
construe it herein includes “work time” as we understand it.
516                        Buero v. Amazon.com Services, Inc.

the Court held that “hours worked” “includes all time during
which an employee is necessarily required to be on the
employer’s premises, on duty or at a prescribed workplace.”
328 US at 690-91. Thus, Rule 4’s definition of “hours worked”
is similar to the pre-Portal-to-Portal-Act understanding of
compensable time, which remains good law as modified by
the Portal-to-Portal Act. See IBP, Inc. v. Alvarez, 546 US
21, 28, 126 S Ct 514, 163 L Ed 2d 288 (2005) (“Other than
its express exceptions for travel to and from the location of
the employee’s ‘principal activity,’ and for activities that are
preliminary or postliminary to that principal activity, the
Portal-to-Portal Act does not purport to change this Court’s
earlier descriptions of the terms ‘work’ and ‘workweek,’ or to
define the term ‘workday.’ ”); see also 29 CFR § 785.7 (quoting
Anderson and explaining that “[t]he Portal-to-Portal Act did
not change the rule except to provide an exemption for pre-
liminary and postliminary activities”).
         Just as the original FLSA was modified by the
Portal-to-Portal Act, Rule 4 is modified by the Hours
Worked series, which specifies the compensability of certain
activities, including, as relevant here, Rule 43, which gov-
erns “preparatory and concluding activities.” Again, Rule 43
provides:
      “(1) Preparatory and concluding activities are con-
   sidered hours worked if the activities performed by the
   employee are an integral and indispensable part of a prin-
   cipal activity for which the employee is employed:
       “(a) Example: A bank teller counts the till and
   arranges the work space in preparation for receiving cus-
   tomers. This activity is an integral and indispensable part
   of the principal activity for which the employee is employed
   and is included as hours worked;
       “(b) Example: In connection with the operation of a
   lathe, the lathe operator oils, greases, or cleans the machine
   or installs a new cutting tool. Such activities are an inte-
   gral and indispensable part of a principal activity and are
   included as hours worked;
       “(c) Example: Agricultural workers must dress in pro-
   tective clothing and thoroughly clean up after their work
   with or around pesticides. The time spent in these activi-
   ties is work time.
Cite as 370 Or 502 (2022)                                                    517

       “(2) These rules are applicable even where there exists
    a custom, contract or agreement not to pay for the time
    spent in such activity.
       “(3) Where a contract, custom or practice dictates cer-
    tain activities to be considered as work time, even though
    not considered to be an integral and indispensable part of
    a principal activity, the time devoted to such activities will
    be considered as work time.”
Section 1 of Rule 43 provides that preparatory and conclud-
ing activities are considered hours worked if they “are an
integral and indispensable part of a principal activity for
which the employee is employed.” Thus, section 1 appears
to establish a condition that must be satisfied in order for
preparatory and concluding activities to be compensable.
Section 3 confirms that understanding. Section 3 provides
that preparatory and concluding activities are compensa-
ble, “even though not considered to be an integral and indis-
pensable part of a principal activity,” if a contract, custom or
practice dictates that they be considered work time. Thus,
reading Rule 43 as a whole, section 1 establishes a require-
ment that must be satisfied for preparatory and concluding
activities to be compensable—specifically, the activities
must be an integral and indispensable part of a principal
activity—and section 3 creates an exception to that require-
ment when a contract, custom, or practice requires that the
activities be compensable. The “even though” clause in sec-
tion 3 shows that Rule 43 limits compensable activities. The
clause has meaning only if section 3 sets forth the sole basis
by which a preparatory or concluding activity that is not an
integral or indispensable part of a principal activity could
be compensable.6
       The text of Rule 43 mirrors the Portal-to-Portal Act
and subsequent case law. In the same way that section 4 of

     6
       Plaintiff, and the dissent, 370 Or at 532-33, contend that Rule 43 simply
lists examples of types of compensable activities. In plaintiff’s view, the purpose
of section 1 of the rule is to identify certain preparatory and concluding activi-
ties that are compensable (those that are integral and indispensable), but not to
preclude compensability for other types of preparatory and concluding activities.
Plaintiff’s reading of the rule cannot be squared with the inclusion of section 3,
which creates an exception to section 1. If section 1 was just an example, there
would be no need for section 3 to include the phrase “even though not considered
to be an integral and indispensable part of a principal activity.”
518                              Buero v. Amazon.com Services, Inc.

the Portal-to-Portal Act provides specific guidance for com-
pensation of “preliminary” or “postliminary” activities, Rule
43 provides specific guidance for compensation of “prepara-
tory” or “concluding” activities. Compare Portal-to-Portal
Act of 1947, § 4(a)(2), 61 Stat at 87, with Rule 43(1). As the
Portal-to-Portal Act requires compensation for preliminary
or postliminary activities as called for by “contract,” “custom
or practice,” so too does Rule 43 require compensation for
preparatory or concluding activities as called for by “con-
tract, custom or practice.” Compare Portal-to-Portal Act of
1947, § 4(b)(1) - (2), 61 Stat at 87, with Rule 43(3).7 And Rule
43 incorporates the precise test that the Supreme Court set
forth when interpreting the Portal-to-Portal Act in Steiner,
and applied in King Packing, for determining whether an
activity that takes place before or after a regular work
shift is compensable: whether that activity is “an integral
and indispensable part” of a principal activity for which the
worker is employed. Steiner, 350 US at 256; King Packing,
350 US at 261; see also 29 CFR § 785.25 (discussing Steiner,
King Packing, and the “integral and indispensable” test).8
      2. Context
         The context provided by the Hours Worked series as
a whole supports our conclusion that, as under federal law,
Rule 43 provides a test for whether time spent in prepara-
tory or concluding activities is compensable. As mentioned,
Rule 40 sets out the purpose of the Hours Worked series. It
     7
       The federal regulations also include analogues to sections 2 and 3 of Rule
43. Compare 29 CFR § 785.8 (providing that, with limited exceptions, hours
worked are compensable irrespective of “custom, contract, or agreement not to
pay for the time so spent”), with Rule 43(2) (providing that “[t]hese rules are
applicable even where there exists a custom, contract or agreement not to pay
for the time spent in such activity”); compare 29 CFR § 790.10(a) (providing that,
under section 4(b) of the Portal-to-Portal Act, otherwise noncompensable “pre-
liminary” or “postliminary” activities might nonetheless be compensable if the
activity is compensable under contract, custom, or practice), with Rule 43(3) (pro-
viding similarly with respect to “preparatory” or “concluding” activities).
     8
       Two of the examples provided in Rule 43 of compensable preparatory and
concluding activities are the same or similar to those in federal law. The exam-
ple in Rule 43(1)(b) involving a lathe operator appears in 29 CFR §§ 785.24 and
790.8(b)(1). And the example in Rule 43(1)(c) involving agricultural workers
required to “dress in protective clothing and thoroughly clean up after their work
with or around pesticides” is analogous to an example of workers in a chemi-
cal plant who must put on protective clothes provided in 29 CFR §§ 785.24 and
790.8(c).
Cite as 370 Or 502 (2022)                                                  519

states that the series “deals with hours worked as defined
by [Rule 4] and discusses principles involved in determin-
ing what constitutes working time for purposes of [Oregon’s
wage statutes] ORS 653.010 to 653.261 and these rules.” In
other words, Rule 4 provides general definitions “unless the
context requires otherwise,” and the Hours Worked series
identifies certain contexts that might require otherwise.
Thus, the definition of “hours worked” in Rule 4 operates
in tandem with the Hours Worked series, Rules 40-47. The
rules in the series set forth various tests and guidelines that
govern whether an employer is—or is not—required to com-
pensate an employee for time the employee spends engaged
in a specific activity; they provide guidance in contexts
where determining compensability might not be straight-
forward. See, e.g., Rule 41 (waiting time); Rule 42 (sleeping
time); Rule 44 (lectures, meetings, and training programs);
Rule 45 (travel time).
     3.    Rulemaking History
         The rulemaking history of Rule 4 and Rule 43 con-
firms that the rules were intended to mirror the Portal-to-
Portal Act. As mentioned, BOLI promulgated the Hours
Worked series following the Oregon legislature’s decision to
extend Oregon’s wage and hour laws to employees already
covered by the FLSA. During BOLI’s rulemaking, Oregon
businesses and attorneys asked BOLI’s Wage and Hour
Division (“the division”) to adopt rules that would align with
federal law as closely as possible.9 Commenters urged the
division to do so in order to “provide consistency and ease
of administration”10 and to avoid “extensive litigation by

        See, e.g., Presiding Officer’s Report, In the Matter of Adoption and
Amendment of Rules Pertaining to Payment of Minimum Wages and Overtime
Pay (Bureau of Labor and Industries) (summarizing hearings from October
and November 1989), 4 (summarizing Exhibit I, a letter from Jerry E. Butler of
NORPAC Foods, Inc., “urg[ing] the Bureau to adopt existing federal standards”);
id. at 7 (summarizing Exhibit AA) (similar); id. (summarizing Exhibit DD) (sim-
ilar); id. at 10 (summarizing Exhibit PP) (similar); id. (summarizing Exhibit RR)

ness will be substantially impacted through having to comply with two laws
which conflict in many areas”); id. at 4 (summarizing Exhibit K, a letter from
Karen Zimmer of Croman Corp. “urge[ing] the Bureau to adopt complete federal

employers regarding what the differences between the pro-
posed rules and Federal regulations mean.”11 In response
to such comments, the division amended several proposed
rules to bring them more in line with federal regulations.12
The division expressly recognized where it declined to adopt
federal regulations and explained its basis for doing so.13
The division did not indicate such an intent to diverge from
federal law regarding what types of activities are compen-
sable. Accordingly, the division’s intent to mirror federal
law is clear. In rejecting several proposed changes, the
division explained that its “desire * * * to mirror federal
law as closely as possible” meant that, “when suggestions
were made to change, expand, or narrow the rules and that
change would have the effect of creating a different standard
or interpretation at the state level, the decision was made
that these modifications not be included.” Presiding Officer’s
Report 28.
         In summary, the text, context, and rulemaking his-
tory of BOLI’s Rule 4 and Rule 43 establish that the rules
were intended to align with federal law, under which pre-
paratory and concluding activities are compensable only if
(1) the activities are an integral and indispensable part of

regulations to avoid confusion”); id. at 5 (summarizing Exhibit M, a letter noting
that mirroring federal regulations “would minimize confusion and avoid two sep-
arate calculations for compliance with both laws”).

of Miller, Nash, Wiener, Hager and Carlsen, Attorneys at Law); see also id. at 10
(summarizing Exhibit SS, a letter warning of litigation resulting from disparate
requirements); id. (summarizing Exhibit TT) (similar).
    12
       For example, in response to comments about a proposed version of OAR
839-020-0005, BOLI remarked:
    “It was suggested by many that the Bureau adopt the language of the federal
    regulations in regard to these particular definitions stating that it would add
    to ease of understanding and interpretation. The Division currently uses the
    federal regulations regarding those definitions when they are not determined
    to be in conflict with state law. * * * Federal language and format have been
    adopted to the extent possible as allowed by law.”
Presiding Officer’s Report 24.
    13
       For example, the division rejected a proposal that it adopt “on a wholesale
basis the federal regulations dealing with overtime,” explaining that doing so
was unnecessary because (1) “[t]he Division currently uses the CFRs as a guide
and relies on federal interpretation where these regulations are not contrary to
statute”; and (2) “[a] significant number of the regulations at the federal level are
contrary to the state statute.” Presiding Officer’s Report 28.

an employee’s principal activities or (2) contract, custom,
or practices requires that they be compensable. The text
of Rule 43 shows that the rule limits the compensability
of preparatory and concluding activities, the context of the
Hours Worked series supports that reading of the text, and
the rulemaking history shows that BOLI intended its rules
to align with federal law as closely as possible. In addition,
nothing in the history indicates that BOLI intended to
diverge from federal law regarding what types of activities
are compensable.14
D. Construction of ORS 653.010(11)
         We turn to plaintiff’s alternative argument that, if
Rule 43 limits compensability for preparatory and conclud-
ing activities, it is inconsistent with ORS 653.010(11), which
defines “work time.” As we will explain, we conclude that
BOLI’s rules are not inconsistent with that statute because,
like BOLI’s rules, the statute’s definition of “work time” was
intended to mirror federal law.
         As mentioned, ORS 653.010(11) provides, “ ‘Work
time includes both time worked and time of authorized
attendance.” Plaintiff argues that the statute requires com-
pensation for time spent in security screenings, because it
is “time of authorized attendance.” To determine the legisla-
ture’s intended meaning of “time of authorized attendance,”
we look to the statute’s text and context, as well as helpful
legislative history. State v. Gaines, 346 Or 160, 171-72, 206
P3d 1042 (2009).
     1. Text
        The text of ORS 653.010(11) indicates that “work
time” covers two distinct categories of activities: (1) “time
worked” and (2) “time of authorized attendance.” See ORS
174.010 (providing that, in the construction of a statute, a
court may not “omit what has been inserted,” and “where
there are several provisions or particulars such construction

    14
       We conclude that BOLI intended the compensability of time spent in pre-
paratory and concluding activities to mirror the compensability of such time
under the then-existing federal law. We do not mean to suggest that all of BOLI’s
concurrently promulgated rules were meant to match federal law. To the con-
trary, BOLI specifically identified areas of departure from federal law.

is, if possible, to be adopted as will give effect to all”).
However, the legislature did not define “time worked” or
“time of authorized attendance.”
         The meaning of “time of authorized attendance” is
ambiguous. The text, viewed in isolation, could plausibly
take on broad meaning. Plaintiff has floated several alterna-
tive constructions, including that “time of authorized atten-
dance” means any time an employee is permitted to be on
the employer’s premises and that “time of authorized atten-
dance” means “the act or state of being in waiting” when
“sanctioned by authority.” Defendants, on the other hand,
have offered several more narrow meanings, including that
“time of authorized attendance” means “time employees
must be present waiting for an assignment”; time spent
“attending lectures, meetings, training programs, and sim-
ilar activities”; or “periods within the workday—between
employees’ first principal activity of the day and their last
principal activity of the day.”
         Because both “authorized” and “attendance” are
words of common usage, we consider their dictionary defi-
nitions. Both words are defined using numerous alternative
senses, leading to disparate results.15 “Authorized atten-
dance” could mean approved presence, approved waiting,
approved service, or approved attendance at an event. None
of the dictionary definitions outweighs the others based on
the text of the statute alone. Therefore, we turn to the con-
text and legislative history.

    15
         The dictionary definitions of “authorized” are as follows:
        “1 archaic : having authority : marked by authority : recognized as hav-
    ing authority 2 : endowed with authority 
    3 : sanctioned by authority : approved  [.]”
Webster’s Third New Int’l Dictionary 147 (unabridged ed 2002). And the defini-
tions of “attendance” are the following:
         “1 : the act or fact of attending: as a : the act or state of being in waiting
    : service esp[ecially] at court or at a hospital 
    b : a being present : presence <[attendance] at a play> 2 : the persons attend-
    ing: a obs : a body of attendants : retinue  b : the persons or number of persons present (as at a public per-
    formance or a session of school) [.]”

     2. Context
          At the same time that the Oregon legislature defined
“work time,” it defined “employ” in the same statute, and the
statute’s definition of “employ” provides relevant context.
Force v. Dept. of Rev., 350 Or 179, 188, 252 P3d 306 (2011)
(“ ‘[C]ontext’ includes, among other things, other parts of the
statute at issue.”). Under the statute, “ ‘[e]mploy’ includes
to suffer or permit to work * * *.” ORS 653.010(2) (1967).16
The FLSA similarly prescribed that “ ‘[e]mploy’ includes
to suffer or permit to work.” 29 USC § 203(g) (1964). The
Oregon legislature derived the definition of “employ” from
federal law. See Cejas Commercial Interiors, Inc. v. Torres-
Lizama, 260 Or App 87, 97-99, 316 P3d 389 (2013) (exam-
ining the text and legislative history and concluding that
the Oregon legislature adopted “the FLSA’s definition of
‘employ’ ” as “an established term of art from federal law”).
And both jurisdictions define “employ” in terms of “work.”
Thus, it is likely that the legislature considered the act of
employing to cover the same scope of work. In other words,
an employer “employs” workers for the same activities under
both state and federal law. Accordingly, the parallel defini-
tions of “employ” support a narrower construction of “work
time” that mirrors the federal understanding of compensa-
ble time.
        Federal law also provides relevant context because
Oregon’s wage statutes were an “offspring” of federal law.
See Badger v. Paulson Investment Co., Inc., 311 Or 14, 21, 803
P2d 1178 (1991) (looking to federal law for guidance when
the 1967 Oregon law was “an offspring of federal security
laws and regulations going back to the 1930s”). Although
the Oregon legislature did not adopt word-for-word every
portion of the FLSA, the legislature drew in large measure
from federal law.17 Accordingly, the well-established federal
    16
       When enacted, the full definition read, “ ‘Employ’ includes to suffer or
permit to work; however, ‘employ’ does not include permitting voluntary service
without compensation to a religious or charitable nonprofit institution.” ORS
653.010(2) (1967).
    17
       Compare ORS 653.010(2) (1967) (“ ‘Employ’ includes to suffer or permit to
work * * *.”), with 29 USC § 203(g) (1964) (“ ‘Employ’ includes to suffer or permit
to work.”); compare ORS 653.010(7) (1967) (defining “outside salesman”), with
29 CFR § 541.500 (1967) (similarly defining “outside salesman”); compare ORS
524                              Buero v. Amazon.com Services, Inc.

understanding of compensable time informs our analysis of
ORS 653.010(11)’s definition of “work time” and supports a
construction in line with federal law.
      3.   Legislative History
          Finally, we examine the relevant legislative his-
tory. As recounted above, the Oregon Legislature enacted
HB 1340 to establish a state minimum wage the year after
Congress had expanded the FLSA. HB 1340 did not cover
employees that were covered by the FLSA. It was intended
to fill a gap in the FLSA’s coverage by providing state pro-
tections to a small number of employees in the state so that
they would have protections similar to what many of them
mistakenly believed they already had under federal law.
Nothing in the legislative history of the bill indicates that the
legislature intended to require compensation for activities
that were not compensable under the FLSA, as modified by
the Portal-to-Portal Act. To the contrary, the Commissioner
of Labor testified that the bill would provide only “the bare
minimum protection to the wage earner.” Tape Recording,
House Committee on Labor and Management, HB 1340,
Mar 10, 1967, Tape 19. Thus, the legislative history indi-
cates that the legislature did not intend to provide more
protections than federal law, much less expand compen-
sability to activities that had not been compensable under

653.020(3) (exempting “[a]n individual engaged in administrative, executive or
professional work who * * * [e]xercises discretion and independent judgment”),
with 29 USC § 213(a)(1) (1964) (exempting an employee employed in an “execu-
tive, administrative, or professional capacity”); 29 CFR § 541.2 (1967) (explain-
ing that an employee employed in an “administrative * * * capacity” includes an
employee “[w]ho customarily and regularly exercise discretion and independent
judgment”); compare ORS 653.020(4) (1967) (exempting “[a]n individual employed
by the United States, or this state, or a political subdivision”), with 29 USC
§ 203(d) (1964) (excluding “the United States or any State or political subdivision
of a State” from the definition of “employer”); compare ORS 653.060 (1967) (mak-
ing it unlawful to “discharge or in any other manner discriminate against any
employe[e]” “[b]ecause the employe[e] has made complaint that he has not been
paid wages,” “[b]ecause the employe[e] has caused to be instituted or is about
to cause to be instituted any proceedings” related to the minimum wage laws,
or “[b]ecause the employe[e] has testified or is about to testify in any such pro-
ceedings”), with 29 USC § 215(a)(3) (1964) (making it unlawful “to discharge or
in any other manner discriminate against any employee because such employee
has filed any complaint or instituted or caused to be instituted any proceeding
under or related to this chapter, or has testified or is about to testify in any such
proceeding”).

federal law since the enactment of the Portal-to-Portal
Act.18
         Moreover, requiring compensation for those activ-
ities would have led to two different rules for determining
compensable time, one for employees subject to the FLSA
and another for employees subject to state wage laws. There
is no indication in the legislative history that the legislature
intended that result.
         To be certain, if the Oregon legislature had wanted
to expand the scope of compensable time beyond the post-
Portal-to-Portal-Act federal scope, it could have done so.
But, if the legislature had wanted to diverge from federal
law, we would expect it to have done so explicitly given the
well-established understanding of what activities were com-
pensable under federal law at the time. But it did not, and
nothing in the legislative history of HB 1340 indicates that
anyone intended the bill to change what types of activities
are compensable.
          Instead, the majority of the legislative discussion
revolved around who should be protected under the law and
who should be exempt. The testimony, debate, and amend-
ments focused on whether agricultural workers, piece-rate
workers, and outside salespeople should be included under
the bill. See, e.g., Tape Recording, House Committee on Labor
and Management, HB 1340, Mar 10, 1967, Tape 19 (Bureau
of Labor chief counsel testifying in favor of removing the
exemption for agricultural workers); id. (testimony from
George Brown, the drafter of the “outside salesman” defi-
nition and exemption); Tape Recording, House Committee
on Labor and Management, HB 1340, Mar 17, 1967, Tape
22 (passing an amendment with the definition of “outside
salesman”); Tape Recording, House Committee on Labor
and Management, HB 1340, Mar 20, 1967, Tape 23 (pass-
ing an amendment clarifying that piece-rate workers were
exempt); Tape Recording, House Floor Debate, HB 1340,

       Neither the definition of “work time” nor the legislature’s intent changed
when Oregon eventually extended coverage under state law to those already pro-
tected by the FLSA with the passage of Senate Bill 335 (1989). Or Laws 1989,
ch 446.

William Stevenson opposing exclusion of agricultural work-
ers); Minutes, Senate Committee on Labor and Industries,
Apr 24, 1967, 1 (testimony from Sen Don Willner discussing
exclusion of piece-rate workers and agricultural workers).
The debate did not cover what activities should be covered.
Nothing in the legislative history suggests that the bill
would institute a new, more expansive definition of “work
time” that would change existing law to require compensa-
tion for all preliminary and postliminary activities, in stark
contrast to federal law.19
         Accordingly, we conclude that the Oregon legisla-
ture did not intend to adopt a broad definition of compensable
time above and beyond the existing federal understanding
and that Oregon’s definition of “work time” aligns with fed-
eral law. The text of the “work time” definition does not pro-
vide a definitive answer; it can be read broadly or narrowly.
But the context and legislative history resolve the ambigu-
ity. The context—the definition of “employ” that matches
federal law and the longstanding federal understanding of
compensable time—suggests that the legislature intended
a narrow meaning that aligns with federal law. And the
legislative history supports a construction that mirrors fed-
eral law. The wage statutes filled a gap in the FLSA’s cover-
age, providing similar coverage to a small group of Oregon
workers. Nothing in the legislative history indicates that
the Oregon legislature intended to diverge from federal law
regarding what types of activities are compensable.
                          III.    CONCLUSION
        To summarize, we conclude that the Oregon stat-
utes and administrative rules regarding what activities
are compensable were intended to mirror federal law. The
structure and text of the relevant administrative rules
mirror federal law, the context of the Hours Worked series
supports reading Rule 43 as a test for whether preparatory
and concluding activities are—or are not—compensable,
    19
       We note that the legislators who adopted the statutory definition of “work
time” acted with knowledge, or at least notice, of federal law. See, e.g., Tape
Recording, House Committee on Labor and Management, HB 1340, Mar 10,
1967, Tape 19 (discussing the 1966 FLSA amendments); Tape Recording, House
Floor Debate, HB 1340, Apr 5, 1967, Tape 12, Side 2 (floor statement explaining
the FLSA’s 1966 amendments).

and the rulemaking history indicates that the rules were
intended to align with federal law as closely as possible.
Likewise, Oregon’s statutory definition of “work time” was
intended to mirror federal law. Although the text of the
definition is ambiguous, the context and legislative his-
tory reveal the legislature’s limited purpose to fill a gap in
coverage. Nothing indicates an intent to diverge from fed-
eral law, which had precluded compensability for certain
activities—including time spent in preliminary and postlim-
inary activities that are not integral and indispensable parts
of an employee’s principal activities nor covered by contract,
custom, or practice—since the enactment of the Portal-to-
Portal Act. Therefore, just as under federal law, whether
time spent waiting for and undergoing mandatory security
screenings on an employer’s premises is compensable under
Oregon law depends on whether the screenings are either
(1) an integral and indispensable part of an employee’s prin-
cipal activities or (2) compensable as a matter of contract,
custom, or practice.
         We recognize that plaintiff’s situation—not receiv-
ing compensation for the time she was required to be on her
employer’s premises for the employer’s benefit—certainly
raises a policy question whether all employees should be
compensated for time spent in mandatory security screen-
ings like those at issue in this case. Now that the scope of
compensable time under existing Oregon law is clear in that
regard, plaintiff may bring the issue to the legislature’s
attention and the legislature may, if it chooses, depart from
federal law and adopt its own standard for compensable
time, consistent with any limits imposed by state and fed-
eral law.
        The certified question is answered.
        FLYNN, J., dissenting.
         At issue in this case is the meaning of administra-
tive rules that define the term “hours worked” for purposes
of the requirement that employers pay their employees at
least minimum wage for “each hour worked.” We typically
determine the meaning of administrative rules by employ-
ing “essentially the same framework that we employ when
interpreting a statute”—we consider primarily “the text of
528                       Buero v. Amazon.com Services, Inc.

the rule in its regulatory and statutory context.” Noble v.
Dept. of Fish and Wildlife, 355 Or 435, 448, 326 P3d 589
(2014). When I follow that methodology for the regulations
at issue here, I reach a different conclusion than does the
majority about what the drafters of the rule intended. I
therefore dissent.
         Starting with the relevant statutory context, the
legislature has created a requirement that, “[e]xcept as
provided” otherwise by statute or by administrative rules,
employers pay a specified minimum wage “for each hour of
work time that the employee is gainfully employed.” ORS
653.025(1). And “unless the context requires otherwise,”
the term “ ‘work time’ includes both time worked and time
of authorized attendance.” ORS 653.010(11). The legisla-
ture has also authorized the Commissioner of the Bureau
of Labor and Industries to “[m]ake such rules as the com-
missioner considers appropriate to carry out the purposes of
ORS 653.010 to 653.261,” ORS 653.040(3), and the commis-
sioner has promulgated rules to further clarify what activ-
ities entitle an employee to be paid wages. Because I agree
with the majority’s conclusion—although not necessarily its
reasoning—that the rules at issue here are not inconsistent
with ORS 653.010, 370 Or at 521, I also answer the certified
question by determining the meaning of the commissioner’s
rules.
         The pertinent rules specify that an “employer is
required to pay each employee” no less than the minimum
wage “for each hour worked by the employee.” OAR 839-020-
0010(1). And they define “hours worked” as “includ[ing]”:
   “all time during which an employee is necessarily required
   to be on the employer’s premises, on duty or at a prescribed
   work place and all time the employee is suffered or permit-
   ted to work. ‘Hours worked’ includes ‘work time’ as defined
   in ORS 653.010(11).”
OAR 839-020-0004(19) (Rule 4(19)). In other words, the rule
identifies multiple categories of time that are “hours worked”
for which the employee must be compensated, one of which
is “time during which an employee is necessarily required
to be on the employer’s premises.” The phrase “necessarily
required” is not defined, but those are terms of ordinary
Cite as 370 Or 502 (2022)                                 529

meaning. And under all ordinary meanings of which I am
aware, the definition would cover time that the employer
requires its employees to spend on its premises perform-
ing security screenings that are a condition of entering and
leaving the area in which the employees perform their prin-
cipal work activities. Although a factfinder might find that
some or all of such time is not in fact “necessarily required,”
we are addressing the meaning of the administrative rules
in response to a certified question, not answering whether
plaintiff will ultimately prevail on the facts.

         The majority recognizes that Rule 4(19) “defines
‘hours worked’ broadly.” 370 Or at 515. But the majority
understands that definition to be limited by another rule,
which specifies that “[p]reparatory and concluding activi-
ties are considered hours worked if the activities performed
by the employee are an integral and indispensable part of
a principal activity for which the employee is employed.”
OAR 839-020-0043(1) (Rule 43(1)). That is, the majority
understands the effect of the more specific provision to be
a “modification” of the definition of “hours worked” so that
Rule 4(19) would be read as providing: “except as limited by
Rule 43, ‘hours worked’ * * * includes all time during which
an employee is necessarily required to be on the employer’s
premises, on duty or at a prescribed work place.”

         In my opinion, however, nothing in the text or con-
text of either rule suggests that the drafters intended Rule
43 to function as a limitation on what qualifies as compen-
sable “hours worked.” Rule 4(19) does not indicate that the
definition of “hours worked” is limited or modified by the
principles articulated in Rule 43. Nor does Rule 43 provide
that “[p]reparatory and concluding activities are considered
hours worked only if” the activity is “an integral and indis-
pensable part of a principal activity for which the employee
is employed.” Instead, another rule explains that Rule 43
merely “deals with” the definition of “hours worked” in Rule
4(19) and “discusses principles involved in determining what
constitutes working time.” OAR 839-020-0040(1) (empha-
sis added). In short, Rule 4(19) tells us that “hours worked”
includes—among other things—“all time during which an
employee is necessarily required to be on the employer’s
530                       Buero v. Amazon.com Services, Inc.

premises, on duty or at a prescribed work place”; and Rule
43 explains the principle that “preparatory and concluding
activities” will always constitute “hours worked” if they are
either “an integral and indispensable part” of the employees’
principal activities or compensable as a matter of “contract,
custom or practice”—regardless of whether the employee is
“necessarily required to” perform them “on the employer’s
premises.”
         The majority reaches a contrary conclusion only
by turning to enactment history indicating that some com-
menters urged the agency to adopt rules that would “provide
consistency and ease of administration” and possibly would
avoid litigation by closely tracking federal law—which we
now know would not require Amazon to compensate employ-
ees for the time spent waiting for and participating in man-
datory screenings on the employer’s premises. See Integrity
Staffing Solutions, Inc. v. Busk, 574 US 27, 35, 135 S Ct
513, 190 L Ed 2d 410 (2014) (identifying employer’s security
screenings as “noncompensable postliminary activities”).
The summary of the exhibits and testimony that were pro-
vided during the rulemaking process indicates that com-
ments on the proposed rules came overwhelmingly from
employers and advocacy organizations for employers, who—
understandably—opposed the burden of any wage require-
ments beyond those that the Federal Fair Labor Standards
Act (FLSA) already imposed. See Presiding Officer’s Report,
In the Matter of Adoption and Amendment of Rules Pertaining
to Payment of Minimum Wages and Overtime Pay (Bureau of
Labor and Industries) (summarizing hearings from October
and November 1989), 2-20.
         But that one-sided commentary does not mean that
the agency intended its rules to reflect the wishes of employ-
ers. For example, in the context of explaining why the agency
had rejected changes that the employers were requesting
to overtime rules that were part of the same rule-making
process, the same presiding officer report explains that the
agency was not simply implementing the wishes of employ-
ers that Oregon law track the federal law:
       “The Division recognizes that the state and federal
   rules regulating these calculations differ significantly. It
   is understood that this will have the effect of placing the

   employer in the position of making them [act] differently in
   order to comply with both laws, but there does not appear
   to be a workable solution in regard to this problem without
   there first being changes made in the law.”
Id. at 28. Ultimately, however, the report does not mean-
ingfully address whether the agency intended the definition
of “hours worked” to mean what the words say. The report
does not recommend approval or rejection of any relevant
change to either that definition or to the “preparatory and
concluding activities” rule. Thus, nothing in the adoption
history of the rules persuades me to ignore the words that
the agency chose in adopting the controlling standards for
which employee activities constitute time that the employer
must compensate.
         In my opinion, those words are the best indication
that the agency did not intend to mirror the federal standard
for whether activities like those at issue here are compensa-
ble. First, the agency defined compensable time as includ-
ing time that the employee is “necessarily required to be
on the employer’s premises,” which had been repudiated as
the federal standard. As the majority recognizes, that defi-
nition tracks the standard that the United States Supreme
Court originally used—prior to the Portal-to-Portal Act—
to determine the time for which employees were entitled to
be paid wages under the FLSA. See 370 Or at 507 (describ-
ing Congress’s adoption of the “Portal-to-Portal Act,” Pub
L 80-49, 61 Stat 84 (1947) (codified as amended at 29 USC
§§ 251-262), in response to the Court’s interpretation of the
FLSA); see also Anderson v. Mt. Clemens Pottery Co., 328 US
680, 690-91, 66 S Ct 1187, 90 L Ed 1515 (1946) (describing
the FLSA requirement that employees be paid for “hours
worked” as reaching “all time during which an employee is
necessarily required to be on the employer’s premises, on
duty or at a prescribed workplace”). But well before Oregon
adopted the rules at issue here, Congress passed the Portal-
to-Portal Act, to “repudiate Anderson’s holding” and elimi-
nate a focus on whether “an employer required an activity.”
Integrity Staffing, 574 US at 36. I am unable to conclude that
the agency intended to mirror federal law when it adopted
a definition of “hours worked” that was directly contrary to
federal law.
532                        Buero v. Amazon.com Services, Inc.

         Typically, that historical context would significantly
inform our understanding of an enactment—we would pre-
sume that the commissioner, when choosing a standard for
“hours worked,” was aware that the chosen standard was
that announced in federal cases that predated the Portal-
to-Portal Act and was not the current federal standard.
Cf. Lindell v. Kalugin, 353 Or 338, 355, 297 P3d 1266 (2013)
(explaining that, “as a general rule, when the Oregon legis-
lature borrows wording” from another jurisdiction, “there is
a presumption that the legislature borrowed the controlling
case law interpreting the statute along with it”); OR-OSHA
v. CBI Services, Inc., 356 Or 577, 593, 341 P3d 701 (2014)
(“Court decisions that existed at the time that the legisla-
ture enacted a statute—and that, as a result, it could have
been aware of—may be consulted in determining what the
legislature intended in enacting the law as part of the con-
text for the legislature’s decision.”).
         Moreover, although Rule 43 borrows somewhat from
federal law in describing “preparatory and concluding”
activities, the rule departs from the federal law in a sig-
nificant way. The Portal-to-Portal Act uses exclusionary
wording to describe compensable “preliminary” or “postlim-
inary” activities:
      “(a) Except as provided in subsection (b), no employer
   shall be subject to any liability or punishment under the

   sation, for or on account of any of the following activities of
   such employee * * *
      “* * * * *
       “(2) activities which are preliminary to or postlim-
   inary to said principal activity or activities, which occur
   either prior to the time on any particular workday at which
   such employee commences, or subsequent to the time on
   any particular workday at which he ceases, such principal
   activity or activities.”
The United States Supreme Court essentially carved out an
exception to that general exclusion for “activities performed
either before or after the regular work shift”: Such activities

are included as compensable time if they “are an integral
and indispensable part of the principal activities for which
covered workmen are employed.” Steiner v. Mitchell, 350 US
247, 256, 76 S Ct 330, 334, 100 L Ed 267 (1956).
         When Oregon adopted Rule 43, it picked up the inclu-
sion from Steiner—preparatory and concluding activities are
compensable “if the activities performed by the employee are
an integral and indispensable part of a principal activity for
which the employee is employed.” OAR 839-020-0043(1). But
Oregon did not adopt a rule to track the Portal-to-Portal
Act’s general exclusion for such activities. In other words,
under the federal approach, there is a rule of inclusion for a
specific range of preparatory and concluding activities, but
such activities are otherwise expressly excluded from what
qualifies as compensable work—regardless of whether the
employee is “necessarily required” to perform them on the
employer’s premises—because the Portal-to-Portal Act had
abrogated that test. By contrast, the rules that govern com-
pensable work in Oregon mirror the federal rule of inclusion
for a specific range of preparatory and concluding activi-
ties, but do not mirror the federal requirement that such
activities are otherwise excluded from hours worked. On the
contrary, Oregon chose to define “hours worked” as mirror-
ing the old federal test—as including all activities that the
employee is “necessarily required” to perform them on the
employer’s premises. Neither defendant nor the majority has
offered a persuasive explanation for why Oregon’s rules mir-
ror a test that the Portal-to-Portal Act had rejected if that
is not the test that the agency intended to adopt. Had the
agency, instead, intended to adopt the Portal-to-Portal Act’s
broad exclusion for most activities performed prior to or sub-
sequent to the principal work activities, it would have been
easy for the agency to do so. And I am unwilling to ignore
that omission.
        For those reasons, I respectfully dissent.
