C ivil action commenced in the Superior Court Department on April 3, 2014. The case was heard by Paul D. Wilson , J. , on a motion for summary judgment. The Supreme Judicial Court on its own initiative transferred the case from the Appeals Court.
Jonathan J. Margolis ( Beth R. Myers also present) for the plaintiff
. Jesse M . Boodoo , Assistant Attorney General, for the defendant

GANTS, C.J. The plaintiff, a lieutenant in the
Massachusetts Sta te p olice, filed suit alleging that he suffered discrimination in violation of G. L. c. 151B, § 4 , when he was unjustifiably denied a trans fer to a different troop station on the basis of his age, race, or national origin. 1 A Superior Court judge granted t he motion of the State p olice for summary judgment, concluding that the plaintiff had not met his burden
of showing that the denial of his request for a lateral transfer

was an "adverse employment action , " a s required to prove an

1 General Laws c. 151B, § 4 (1) , provides that it is an unlawful practice for an employer to "refuse to hire or employ or to bar or to discharge from employment [an] individual or to discriminate against such individual," on the basis of a protected status such as race or national origin, "in compensation or in terms, conditions or privileges of employment, unless based on a bona fide occupational qualification." The Commonwealth and its political subdivisions , including the State p olice, are covered by c. 151B. Bain v. Springfield , 424 Mass. 758, 763 (1997). The provision of c. 151B governing age discrimination distinguishes between private sector employers and the government as an employer. The section spe cifically covering the Commonwealth and its subdivisions is phrased somewhat differently from the section covering private employers
. Compare G. L. c. 151B, § 4 (1C) , with G. L. c. 151B, § 4 (1B). Section 4 (1C) provides that it is unlawful "[f]or the commonwealth or any of its political subdivisions, by itself or its agent, because of the age of any individual, to refuse to hire or employ or to bar or discharge from employment such individual in compensation or in terms, conditions or privileges of employment unless pursuant to any other general or special law." Because the State p olice have not alleged that Yee's claim falls outside the scope of this section, we decline to address whether the statute's omission of "discriminat[ion ]" would bar a claim for refusal to grant a request for transfer.3

employment discrimination claim under c. 151B. We hold that where there are material differences between two positions in the opportunity to earn compensation, or in the terms, conditions, or privileges of employment, the failure to grant a lateral transfer to the preferred posit ion may constitute an adverse employment action under c. 151B. Because the plaintiff has offered adequate evidence that he would have greater opportunities to earn overtime and obtain paid details in the troop to which he seeks transfer, we vacate the allowance of summary judgment and remand the case for further proceedings
. 2 Background
. We s et forth the relevant facts in the summary judgment record in the light most favorable to the nonmoving party, which in this case is the plaintiff , reserving some facts for our subsequent discussion of the legal issues. 3 See Carey v. New England Organ Bank , 446 Mass. 270, 273 (2006). The plaintiff, Warren Yee , was born in Hong Kong in 1954 and later immigrated and became a citizen of the United States. He

identifies as a Chinese Asian

- American. Yee began working as a police officer for the Massachusetts District Commission (MDC) in 1980. He was promoted to the position of sergeant in 1986,

a nd was later transferred to the Massachusetts State p olice in 1992 , after the State p olice merged with the MDC. In 1998, he was promoted to the position of lieutenant. From 2005 until at least the time this complaint was filed , he has served as a lieutenant shift commander at the headquarters of State p olice Troop H, located in the South Boston section of Boston
. In December 2008, Yee requested a transfer to State p olice Troop F, the unit headquartered at Logan International Airport in the East Boston section of Boston . State police lieutenants earn the same base pay and benefits regardless of station, but
Yee testified that he wanted to transfer to Troop F because he "knew that there was better overtime and [paid detail s] at Troop
F. " 4 Yee cla ims to have "taken steps to keep his interest in that transfer known to his superiors continuously since that request was first made." The State p olice ha s no written policy governing transfers of lieutenants . W hen there is an open position for a lieutenant in a troop , the troop commander nominates a candidate , but the

4 Lieutenant Warren Yee speaks Chinese , and he testified t hat he also wanted to transfer to Troop F because he could "be useful" at the airport, where there were many travelers of Asian descent
.5

decision whether to approve the nomination rests with the Superintendent of the State p olice
. The troop commander has broad discretion in nominating a candidate for transfer. During the time period between his initial 2008 request and September 2012, the State p olice had eith er transferred or promoted seven troopers to Troop F in the position of lieutenant; all were white males
. Five out of those seven troopers were younger than Yee when they became Troop F lieutenants
. Yee was never offered a transfer to Troop F and

was never interviewed regarding a transfer position
. On September 20, 2012, Yee wrote a letter to the Superintendent and others complaining of discrimination on the basis of his age or ethnic background
. On September 23 , 2012 , t wo days after the letter was received , a forty

- nine year old white male police sergeant in Troop H, Shawn Lydon , was promoted to lieutenant and transferred to Troop F even though he had not requested a transfer to Troop F. Lydon served in Troop F for approximately two years, during which time he earned over $30,000 more per year in overtime and detail pay than he had
when he served in Troop H. When Lydon w as later transferred back to Troop H, his annual overtime and detail earnings dropped by about $30,000 per year . After Yee sent his letter complaining of discrimination, at least two other lieutenants6

apart from Lydon were transferred to or promoted within Troop F ; both were white males. On April 3, 2014, Yee filed a complaint in the Superior Court, alleging that the State p olice discriminated against him on the basis of race, age , and national origin by failing to transfer him to Troop F. The State p olice moved for summary judgment, contending that no adverse employment action had been taken against Yee and that , even if there had been , there was no discriminatory animus that motivated the State p olice's decision not to transfer him.
The judge granted the motion for summary judgment, concluding that the summary judgment record would not permit a jury reasonably to find that Yee "was subjected to an adverse employment action when the State p olice declined to transfer him laterally from one troop to another ." Citing MacCormack v. Boston Edison Co ., 423 Mass. 652, 663 (1996), the judge declared that a plaintiff who bring s an employment discrimination claim "must show an adverse employment action that materially changes objective aspects of the plaintiff's employment." In the context of this case, t he judge determined that, for Yee to avoid summary judgment, there ne eded to be sufficient evidence in the record to allow a jury reasonably to conclude that Yee "lost money when the State [ p ] olice declined to transfer him to Troop F ," either by showing that "a lieutenant at Troop F7

automatically earned more money than a lieuten ant at Troop H ," or by presenting "statistical data showing that lieutenants at [Troop F] routinely earn more money than lieutenants at [Troop H] ." The judge found that the only evidence of a "potential earnings differential between Troop H and Troop F" w as the additional income that Lydon earned from overtime and details when he transferred from Troop H to Troop F, and his corresponding drop in these earnings after he returned to Troop
H. The judge concluded that this evidence was insufficient to defeat summary judgment because it was "entirely anecdotal, concerning the experience of only one of the nine potential comparators who became lieutenants at Troop F in the relevant period," and because Yee had offered no evidence that would permit a reasonable jury to conclude that Yee "would have worked the same paid details and just as much overtime" as Lydon did.
Yee timely appealed. We transferred Yee's appeal to this court on our own motion to decide whether the denial of his request for a lateral transfe r may constitute an adverse employment action under G. L. c. 151B, § 4, and if so, whether
the motion judge erred in granting the S tate p olice's motion for summary judgment. Discussion
. Our review on summary judgment is de novo

claim survive s a motion for summary judgment , we apply the three

- stage, burden

- shifting framework from McDonnell Douglas Corp . v. Green , 411 U.S. 792, 802

- 805 (19 7 3) ( McDonnell Douglas ). See Bulwer v. Mount Auburn Hosp ., 473 Mass. 672, 680

- 681 (2016). We discuss each st age of the McDonnell Douglas framework in turn
. 1. Adverse employment action
. Under the first stage of McDonnell Douglas , Yee bears the burden of producing evidence of a prima facie case of discrimination that would allow a jury to infer that: (1) he is a member of a class protected by G. L.

c. 151B; (2) he performed his job at Troop H at an acceptable level; (3) h is transfer request was treated differently from
that of another person who was not a member of his protected class but otherwise was similarly situated; and (4) the continued denial of his request for a lateral transfer to Troop F was an adverse employment action. 5 See Trustees of Health & Hosps. of Boston, Inc . v. Massachusetts Comm'n Against Discrimination , 449 Mass. 675, 681

- 682 (2007) ( Trustees of Health & Hosps .); Verdrager v. Mintz, Levin, Cohn, Ferris, Glovsky & Popeo, P.C ., 474 Mass. 382, 396 (2016). The State

5 The elements of the prima facie case may vary depending on the nature of the discrimination claim. See McDonnell Douglas Corp . v. Green , 411 U.S. 792, 802 n.13 (1973); Wheelock College v. Massachusetts Comm'n Against Discrimination , 371 Mass. 130, 135 n.5 (1976).9

p olice contends that Yee failed to meet this burden only because the denial of a lateral transfer from one troop to another is not an adverse employment action.
The phrase " a dverse employmen t action" does not appear in
G. L. c. 151B , but we use the phrase to determine when an act of discrimination against an employee "in compensation or in terms , conditions or privileges of employment " may be remedied under

c. 151B. 6 Where an employer discriminates against an employee

6 We often do not distinguish among "terms," "conditions," and "privileges" of employment , or attempt to define them separately . See, e.g., College

- Town, Div. of Interco, Inc . v. Massachusetts Comm'n Against Discrimination , 400 Mass. 156, 162 (1987) ("Clearly, within the broad sweep o f [terms, conditions, or privileges of employment] falls conduct which creates a sexually harassing work environ ment"); Lopez v. Commonwealth , 463 Mass. 696, 707 (2012) (right to equal opportunities for promotion without discrimination falls within "right to be free from discrimination in the terms, conditions, and pri vileges of employment"). We attempt to do so here, defining these words as they are commonly used in our case law , albeit recognizing that th e phrase "terms, conditions, or privileges" is "general and broad, and must be determined on a case by case basis" (quotation and citation omitted). Sch ool Comm. of Newton v. Newton Sch. Custodians Ass'n, Local 454, SEIU , 438 Mass. 739, 749 (2003). See also Randlett v. Shalala , 118 F.3d 857, 862 (1st Cir. 1997) (same language in Title VII is "pretty open

ended"). We therefore decline to attach any strict limits to the definitions we offer. The "term s of employment " govern the employment relationship , such as personnel policies , see Weber v. Community Teamwork , 434 Mass. 761, 780

- 781 (2001), or contractual provisions that may be either explicit or implied. See Black's Law Dictionary 1698

- 1699 (10th ed. 2014). The "condition s of employment" may refer to the economic or financial conditions of employment, see Meritor Sav. Bank, FSB v. Vinson , 477 U.S. 57, 64 (1986) , such as wages and hours,10

but the discriminatory act falls shor t of being an "adverse employment action," c. 151B affords the employee no remedy for the discrimination
. King v. Boston , 71 Mass. App. Ct. 460, 469 (2008) ("a successful claim of employment discrimination

vacation pay, and sick leave, and therefore some may overlap with both the "terms of employment" and "compensation." See G. L. c. 151B, § 4 (1). "Conditions of employment" may also encompass the general environment, atmosphere, or quality of the work place . See , e.g., Ocean Spray Cranberries, Inc . v. Massachusetts Comm'n Against Discrimination , 441 Mass. 632, 648 (2004); Gilbert's Case , 253 Mass. 538, 540 (1925); Windross v. Village Automotive Group, Inc ., 71 Mass. App. Ct. 861, 868

- 869 (2008). For example, the conditions of employment are often discussed in sexual harassment cases in the context of the creation of an abusive working environment . See , e.g., Meritor Sav. Bank, FSB , supra at 67; McKenzie v. Illinois Dep 't of Transp ., 92 F.3d 473, 479 (7th Cir. 1996).
A "privilege of employment" is an unmandated benefit that, "though not a contractual right of employment," is nonetheless customarily provided by an employer to its employees, and is therefore "part and parcel of the employment relationship [and] may not be doled out in a discriminatory fashion." Hishon v. King & Spalding , 467 U.S. 69, 75 (1984) . See also Randlett , supra at 862 (hardship transfer s were commonly granted by employer and therefore were "arguably a 'privilege ' of employment"); Blackie v. Maine , 75 F.3d 716, 726 (1st Cir. 1996)
. Our definitions of terms, conditions, and privileges of employment here are limited to the context of enforcement of G. L. c. 151B. We recognize , for example, that pursuant to G. L. c. 150E, § 6, municipalities are required to negotiate with public employee unions with respect to the "terms and conditions" of union member employment. As to the definition s of terms and conditions of employment in that context, we refer to our existing case law. See, e.g., Somerville v. Commonwealth Employment Relations Bd ., 470 Mass. 563, 570 (2015) (municipal contributions to retiree health insurance premiums not " term o r condition of employment" subject to mandatory collective bargaining).11

requires a showing that the plaintiff has been subjected to some adverse action that is material"). Therefore, in defining the phrase, we are essentially defining the remedial scope of

c. 151B. Because the Legislature has directed that c. 151B "shall be construed liberally for the accomplishment of i ts purposes," G. L. c. 151B, § 9 , we must define the phrase with the liberality required to meet the statute's broad remedial goals. See Depianti v. Jan

- Pro Franchising Int'l, Inc ., 465 Mass. 607, 620 (2013) ("Employment statutes in particular are to be liberally construed, with some imagination of the purposes which lie behind them" [quotation and citation omitted]). "Cases have employed the phrase 'adverse employment action'
to refer to the effects on working terms, conditions, or privileges that are material, and thus governed by the statute, as opposed to those effects that are trivial and so not properly the subject of a discrimination claim. " King , 71 Mass. App. Ct.
at 468 , and cases cited. We have said that an action taken by an employer is an "adverse employment action" w he re it is

" substantial enough to have materially disadvantaged an employee ." Psy

- Ed Corp . v. Klein , 459 Mass. 697, 707

- 7 08 (2011). "Material disadvantage for this purpose arises when objective aspects of the work environment are affected." King , supra . The disadvantage must be objectively apparent to a reasonable person in the employee's position; "subjective12

feelings of disappointm ent and disillusionment" will not suffice. MacCormack , 423 Mass. at 663. Because we focus on a reasonable person in the employee's position, we examine whether an employee has suffered an "adverse employment action" on a

case - by

- case basis. King , supra at 470, quo ting Blackie v. Maine , 75 F.3d 716, 725 (1st Cir. 1996)
. A lateral transfer from an evening to a day shift may be an adverse employment action to one employee, but be welcomed by another. See Bell v. Gonzales , 398 F. Supp. 2d 78, 97 (D.D.C. 2 005) (whether loss of overtime constitutes adverse employment action is fact

- specific inquiry because some employees desire to work overtime and others do not). Here, Yee contends that the failure to grant him the transfer was an adverse employment action because Troop F offered more opportunities for overtime and paid details than Troop H and therefore offered him a greater opportunity to increase his over

- all compensation, even though his base salary and benefits would be unaffected by the transfer. We have not previously reached the question whether a failure to grant a lateral transfer may constitute an adverse employment action
. T he failure to grant a lateral transfer is ce rtainly an "employment action" by an employer where an employee with superviso ry authority, whose actions we impute to the employer,

see College

- Town, Div. of Interco, Inc . v. Massachusetts Comm'n13

Against Discrimination , 400 Mass. 156, 16 5 (1987) , makes a decision to choose someone else for the lateral position or decides not to tra nsfer the employee seeking the transfer to that position. See Weber v. Community Teamwork, Inc ., 434 Mass. 761, 767

- 769 (2001). And the denial of a transfer to a n employee is undoubtedly "adverse" where it would deprive the employee of the potential to earn additional "compensation," which

-- if motivated by discriminatory animus

-- G. L. c. 151B, § 4 , expressly forbids. We thus conclude that where an employee can show that there are material differences between two positions in the opportunity for compensation, or in the terms, conditions, or privileges of employment, the failure to grant a lateral transfer to the preferred position may const itute an adverse employment action under c. 151B. See Harrison v. Boston Fin. Data Servs., Inc ., 37 Mass. App. Ct. 133, 137

- 138 (1994) (employee made out prima facie case of discrimination by asserting, inter alia, that she was not provided with training and educational opportunities given to white employees). We note that a number of F ederal courts have confronted this question and arrived at the same conclusion. In interpreting G. L. c. 151B, we often look to case law construing
the analogous Title VII of the Civil Rights Act of 1964, as14

amended, 42 U.S.C. § 2000e

- 2(a ) (1) (Title VII). 7 S ee , e.g., College

- Town, Div. of Interco, Inc ., 400 Mass. at 163; Brown v. F.L. Roberts & Co ., 452 Mass. 674, 680 (2008). A number of Federal courts have expressly h eld that the denial of opportunities to work overtime may suffice to support an unlawful discrimination claim . See , e.g., Garmon v. Nat ional R.R. Passenger Corp ., 844 F.3d 307, 314 ( 1st Cir. 2016) ("decreased overtime opportunities could cause a 'material ' change in the conditions of a plaintiff's employment") ; Lewis v. Chicago , 496 F.3d 645, 654 (7th Cir. 2007) ( denial to Chicago police officer of opportunity to travel to Washington, D.C. , to work detail assignment i nvolving crowd control was adverse action, not only because she would have been paid overtime for

7 Title 42 U.S.C. § 2000e

- 2(a) (1) provides , in part :

" It shall be an unlawful employment practice for an employer

--

" (1) to fail or refuse to hire or to discharge any individual, or otherwise to discriminate against any individual with respect to his compensation, terms, conditions, or privileges of employment, because of such individual's race, color, religion, sex, or national origin

. . . . "
We also may look to employment cases interpreting 42 U.S.C. § 1981, which applies the same legal framework as Title VII. Bhatti v. Trustees of Boston Univ ., 659 F.3d 64, 70 ( 1st Cir. 201 1). Title 42 U.S.C. § 1981 (a) and (b) similarly prescribes: "All persons . . . shall have the same right . . . to make and enforce contracts . . . [including] the enjoyment of all benefits, privileges, terms, and conditions of the contractual relationship."15

that particular assignment , but also because " she lost her ability to move forward in the component of her career of being a police officer at recurring large scale public gatherings " and, in turn, " lost the potential to earn many hours of overtime " in future ) ; Robinson v. Dist rict of Columbia , 275 F. Supp. 3d 95, 105

- 1 06 (D.D.C. 2017) (potential for lost overtime
pay may constitute adverse action where it was known to employer that employee desired opportunity to work overtime); Bell , 398 F. Supp. 2d at 97

- 98 (same) . See also Mazyck v. Metro. Transp. Auth
. , 893 F. Supp. 2d 574, 589 (S.D.N.Y. 2012) (lost opportunities to earn overtime pay constituted adverse employment action) . Cf. Bush v. Am erican Honda Motor Co ., 227 F. Supp. 2d 780, 790 n.8 (S.D. Oh. 2002) (lost opportunity to receive potential future bonuses or promotions may amount to adverse employment action)
. 8 I t would be a curious result for us

8 In this analysis, our citations to Federal cases concern discussions of Title VII discrimination claims, as opposed to retaliation claims. A split in the Federal Courts of Appeal s existed regarding whether the meaning of an "adverse action" differed between discrimination and re taliat ion claims under Title VII until the Supreme Court resolved the dispute in Burlington N . & Santa Fe R. R . v. White , 548 U.S. 53, 60, 64 (2006) . The Supreme Court held that adverse actions under the antidiscrimination provision are limited to conduct affecting "compensation, terms, conditions, or privileges of employment," id . at 62, but in the antiretaliation context, the challenged action must only have "dissuaded a reasonable worker from makin g or supporting a charge of discrimination" (citation omitted ) , i d . at 68. In deciding this case, we need not reach the question whether to apply a different standard to defining16

to interpret c. 151B to provide less protection against employment discrimination than Title VII , given that we at times interpret G. L. c. 151B to provide more protection against employment discrimination than Title VII, in part because of the Legislature's direct ion that c. 151B is to be applied liberally
. Se e G. L. c. 151B, § 9 ; Cuddyer v. Stop & Shop Superm kt. Co ., 434 Mass. 521, 536 (2001). There is no suc h comparable la nguage in Title VII
. We reject the argument of the State p olice that the denial of a lateral transfer may be an adverse employment action only whe re the transfer would have constituted a promotion. To satisfy the element of an adverse employment action in the prima facie case , it suffices that an employee who is denied a lateral

adverse employment actions in the retaliation context under G. L. c. 151B. Additionally, in citing to F ederal cases that support Yee's claim that loss of opportunity to earn overtime and paid detail compensation may constitute an adverse employment action, w e are aware that another provision of Title VII

-- 42 U.S.C. § 2000e

2(a )(2)

-- provides that it is an unlawful practice for an employer "to limit, segregate, or classify his employees or applicants for employment in any way which would deprive or tend to deprive any individual of employment opportunities or otherwise adversely affect his status as an employee, because of such individual's race, color, religion, sex, or national origin " (emphasis added)
. G eneral L aws c. 151B does not contain a comparable provision expressly referencing "employment opportu nities." However, none of the cases discussed herein relies on § 2000e

- 2(a)(2) or its reference to " employment opportunities." We are therefore satisfied that it is proper to consider F ederal Title VII cases that have analyzed the comparable adverse acti on requirement.17

transfer put s forward evidence of any "objective indicator of desirability" that would "permit a reasonable factfinder to conclude that the sought for position is materially more advantageous." Beyer v. C oun ty of Nassau , 524 F.3d 160, 165 (2d Cir. 2008). We conclude that Yee's desire to transfer to a troop where he had more opportunity to earn additional compensation through the greater availability of overtime and paid details is an objective indicator of desirability. 9 The closer question is whether Yee met his burden of producing adequate evidence that Troop F offered greater opportunities for overtime and paid details than Troop H . The only evidence before us, other than Yee's own assertions, is testimony from a single comparator , Lydon, who earned approximately $30,000 more per year in overtime and detail compensation during the two years after he left Troop H to work

9 Because Yee argues that the denial of his requested lateral transfer was an adverse employment action primarily because it denied him the potential for additional compensation through overtime and detail pay, we do not address whether the denial of the lateral transfer would have been an adverse employment action had he sought the transfer only to use his Chinese language skills to assist Chinese visitors who use the airport. Nor do we addres s whether an emplo yee would have a viable discrimination claim

-- on the basis of a hostile work environment or a denial of a "privilege" of employment, such as being considered for a customary benefit , see King v. Boston , 71 Mass. App. Ct. 460, 471 (2008), citing Hishon , 4 67 U.S. at 76

.18

in Troop F, and then ea rned approximately $30,000 less per year after he was transferred back to Troop H. In evaluating whether Yee met this threshold showing, we note that the "initial burden of establishing a prima facie case is not intended to be
onerous." Trustees of Healt h & Hosps . , 449 Mass. at 683, quoting Sullivan v. Liberty Mut. Ins. Co
. , 444 Mass. 34, 45 (2005) . "It is meant to be a 'small showing' that is 'easily
made.'" Truste e s of Health & Hosps . , supra , quoting Ch ungchi
Ch e v. Massachusetts Bay Transp. Auth
. , 342 F.3d 31, 38 (1st Cir. 2003). To establish a prima facie case, the plaintiff bears only the burden of production, which is satisfied by furnishing evidence in support of each element; the burden of persuasion that an element of the prima facie case h as not been established rests with the defendant on summary judgment, even though it rests with the plaintiff at trial. Sullivan , supra at 39
. As to the evidence proffered by the plaintiff, we view it in the light most favorable to the plaintiff, accepti ng all reasonable inferences favoring the plaintiff that flow from that evidence. Premier Capital, LLC v. KMZ, Inc ., 464 Mass. 467,
474

- 475 (2013)
. Generally, comparator evidence is intended to prove discrimination, such as where an employee who claims s he was rejected from a job because of discrimination offers evidence that the person who obtained the position was less qualified19

than she. Trustees of Health & Hosps ., 449 Mass. at 682

- 683. Here, Yee offered comparator evidence, to show both that he was denied the lateral transfer because of his race, national origin , or age, and that the denial of the lateral position was an adverse employment action because of the comparator's change in earnings at Troop F. We recognize that the summary ju dgment record regarding the difference in potential earnings from overtime and paid details between Troop H and Troop F is rather sparse, where it is limited to the change in earnings of a single comparator, but we
conclude that it suffices to yield a genu ine dispute of material fact as to this element of the prima facie case of discrimination . Lydon was a close comparator to Yee; he had been assigned to Troop H before being promoted to lieutenant ,

was transferred to Troop F, and then returned to Troop H. It is theoretically possible that the opportunities for overtime and paid details were the same in Troop H and Troop F, and that Lydon simply availed himself of more of those opportunities when he tra nsferred to Troop F, and then chose not to when he returned to Troop H. But it is a more reasonable inference

-- and one to which Yee is entitled at summary judgment

-- that Lydon's increase in earnings from overtime and paid details derived, at least in part, from the greater opportunities available in Troop F to work overtime and obtain paid details.20

And, although the State p olice was in possession of evidence regarding the earnings from overtime and paid details of the other potential comparators, it d id not offer such evidence to satisfy its burden of persuasion that the earnings opportunities were the same in Troop F as in Troop H. Although evidence from a single comparator m ight prove to be insufficient to prevail at trial, we require only a modest evidentiary showing from plaintiffs to satisfy the prima facie stage of summary judgment
. Therefore, we conclude that the judge erred in determining that Yee had failed to meet his burden of showing a prima facie case of discrimination. 2
. Discrimination
. Because the judge granted summary judgment to the State p olice on the ground that Yee had failed to show an adverse employment action, he never reached the issue whether there was a genuine issue of material fact whether the denial of Yee' s request for a lateral transfer was motivated by discriminatory animus. We exercise our discretion to re mand the
matter to the motion judge to allow him to decide this issue.

v. Edward G. Boyle Ins. Agency, Inc ., 402 Mass. 815, 819 (1988). On remand , the motion judge will need to apply the second and third stage s of the McDonnell Douglas summary judgment framework. At the second McDonnell Douglas stage , where the employee has successfully made out a prima facie case, "the21

burden of production shifts to the employer to articulat [ e ] a legitimate, nondiscriminatory reason" for its decision to take the adverse action (quotation omitted)
. Verdrager , 474 Mass. at 39 7, quoting Blare v. Husky Injection Molding Sys. Boston, Inc ., 419 Mass. 437, 441 (1995). The burden of the State p olice here is not meant to be onerous. Blare , supra at 442. Even if the reasons given are arguably suspect, so long as the State p olice
ha s produced a lawful reason bac ked by some credible evidence, it has satisfied th is burden. Matthews v. Ocean Spray Cranberries, Inc
. , 426 Mass. 122, 128 (1997) . However, its explanation must not be wholly unbelievable such that an underlying discriminato ry motive is obvious. See Wheelock College v. Massachusetts Comm'n Against Discrimination , 371 Mass. 130, 138 (1976)
. If the judge c onclude s that t he State p olice ha s carri ed its burden of rebutting Yee's prima facie case with a nondiscriminatory explanation for denying Yee's request for the
lateral transfer , the judge will reach the third and final McDonnell Douglas stage, w here the burden of production shifts
back to Yee to "produce evidence that the employer's articulated justification [for the adverse action] is not true but a pretext." Verdrager , 474 Mass. at 397, quoting Blare , 419 Mass. at 443. Yee may satisfy this burden by offering evidence which , when viewed in the light most favorable to Yee, is sufficient to22

convince a reasonable jury that the reasons the State p olice
offered for transferring Lydon instead of him were not the real

reasons , thereby inviting the inference that discrimination was
the mot ivating reason. See Verdrager , supra . Finally, although we have denied Yee's motion to supplement the summary judgment record on appeal , see n ote 3 , supra , we recognize that a developed factual record is particularly critical where, as here, wholly subjective procedures are used
to determine which candidates receive a lateral transfer. See Smith Coll ege v. Massachusetts Comm'n Against Discrimination , 376 Mass. 221, 231 (1978) (" [ T ] he opportunity for u nlawful bias is particularly great in such cases. A most detailed and careful analysis of the facts is required")
. On remand, the motion judge may decide whether to permit the parties to supplement the summary judgment record in determining whether there is a genuine issue of material fact whether the denial of Yee's request for a lateral transfer was motivated by discriminatory animus. Conclusion
. The order allowing the motion of the State
p olice for summary judgment is vacated , and the case is remanded
to the motion judge to determine whether there is a genuine issue of material fact whether discrimination was the motivating reason for the denial of the plaintiff's request for transfer.
So ordered
