ON BRIEF: Pamela L. Ashby, JACKSON & ASSOCIATES LAW FIRM, LLC, Upper Marlboro, Maryland, for Appellant. Lincoln O. Bisbee, New York, New York, Bryan Killian, Brendan J. Anderson, Mathew J. McKenna, MORGAN, LEWIS & BOCKIUS LLP, Washington, D.C., for Appellee.

GROH, District Judge:
In this employment case, Tiffany Burnett asks us to consider whether the district
court incorrectly granted her former employer’s motion for summary judgment. Ms.
Burnett worked for AstraZeneca from 2013 until it terminated her employment on
November 4, 2019. Although the complaint contained eight counts, only Ms. Burnett’s
claims for retaliation and violations of the Equal Pay Act are before us.
I.
We must first address the record in this case. Ms. Burnett’s response to the motion
for summary judgment was untimely filed, and AstraZeneca moved the district court to
strike it. The district court granted AstraZeneca’s motion and struck Ms. Burnett’s
response. However, the court still considered Ms. Burnett’s timely filed cover opposition,
statement of material facts in dispute, exhibits, and proposed order. J.A. 989. The district
court’s ruling on AstraZeneca’s motion to strike is not part of this appeal. We therefore
consider Ms. Burnett’s arguments on appeal within the confines of the record accepted and
utilized by the district court that is unchallenged before us.
II.
Our review of a district court’s grant of summary judgment is de novo. French v.
Assurance Co. of Am., 448 F.3d 693, 700 (4th Cir. 2006). “Summary judgment is
appropriate when there is no genuine issue of material fact and the moving party is entitled
to judgment as a matter of law.” Id.; Fed. R. Civ. P. 56(a). “To create a genuine issue for
trial, ‘the nonmoving party must rely on more than conclusory allegations, mere
speculation, the building of one inference upon another, or the mere existence of a scintilla
2 USCA4 Appeal: 25-1029 Doc: 50 Filed: 03/20/2026 Pg: 3 of 6
of evidence.’” Humphreys & Partners Architects, L.P. v. Lessard Design, Inc., 790 F.3d
532, 540 (June 24, 2015) (quoting Dash v. Mayweather, 731 F.3d 303, 311 (4th Cir.2013)).
III.
“To make a prima facie claim of retaliation, a plaintiff must show: (1) that she
engaged in protected activity, (2) that the employer took a materially adverse action against
her and (3) there is a causal connection between the protected activity and the adverse
action.” Evans v. Int'l Paper Co., 936 F.3d 183, 195 (4th Cir. 2019) (citing Burlington N.
& S.F.R. Co. v. White, 548 U.S. 53, 61–68 (2006); King v. Rumsfeld, 328 F.3d 145, 150–
51 (4th Cir. 2003)).
Ms. Burnett presents two retaliation theories. First, she claims that after complaining
about her pay, AstraZeneca retaliated by firing her. Second, she avers that it retaliated
against her by barring her from finding another position. The facts support neither theory.
AstraZeneca reorganized Ms. Burnett’s team in 2019. J.A. 142. Because Ms.
Burnett was not selected to become part of the new team, AstraZeneca gave her 60 days to
find another position. J.A. 142–43. Similarly situated individuals received the same deal.
Id.; J.A. 37–38. However, Ms. Burnett received a dedicated internal recruiter to assist her
with her job search even though none of the other employees displaced by the
reorganization received one. J.A. 38.
Ten days after receiving her 60-day notice, Ms. Burnett emailed AstraZeneca’s
general counsel to raise allegations of pay inequity and retaliation. J.A. 183–85. Ms.
Burnett only applied to a few positions, and they were all in research and development.
J.A. 735–37; J.A. 744. She did not find another position, so AstraZeneca terminated her—
3 USCA4 Appeal: 25-1029 Doc: 50 Filed: 03/20/2026 Pg: 4 of 6
just like it told her it would. J.A. 38. The district court held that Ms. Burnett failed to
establish any causal connection between her email to AstraZeneca’s General Counsel (the
protected activity) on September 9, 2019, and her termination from the company on
November 1, 2019. J.A. 1006-07.
When a company tells an employee that it is going to follow specific steps regarding
an employee’s termination, and then it follows the plan it outlined, courts cannot presume
that the company fired the employee in retaliation for some intervening protected activity.
See Clark Cnty. Sch. Dist. v. Breeden, 532 U.S. 268, 272 (2001). That is the exact fact
pattern this case presents. In short, Ms. Burnett fails to show retaliation caused her firing.
Nor has she shown that AstraZeneca retaliated against her by preventing her from
securing another role in the company. If anything, AstraZeneca gave Ms. Burnett extra
help when compared to others. Sanne Bellemans, whom Ms. Burnett claims retaliated
against her, was not involved in research and development hiring. J.A. 943–44. Ms. Burnett
has not cited any evidence beyond her own speculation that Bellemans played any role in
“prevent[ing] her from obtaining another position.” Appellant’s Br. at 22.
Ms. Burnett similarly fails to establish that the individuals who made hiring
decisions in research and development knew about her pay-equity complaint when they
did not hire her for those positions. Accordingly, Ms. Burnett cannot adequately make a
claim that those hiring managers selected other candidates to retaliate against her. See
Roberts v. Glenn Indus. Grp., Inc., 998 F.3d 111, 122 (4th Cir. 2021) (knowledge of the
protected activity by the decisionmaker “is absolutely necessary to establish . . . a prima
facie case.” (citation omitted)).

The district court correctly found that Ms. Burnett presented no evidence of
retaliation beyond her own mere speculation. Because no evidence of retaliation exists,
AstraZeneca was entitled to judgment as a matter of law.
IV.
Ms. Burnett’s Equal Pay Act claim is even more straightforward than her retaliation
claim. A plaintiff must identify an employee of the opposite sex who was paid more “for
equal work” for a position “requiring equal skill, effort, and responsibility,” “performed
under similar working conditions.” U.S. Equal Opp. Employment Comm’n v. Md. Ins.
Admin., 879 F.3d 114, 120 (4th Cir. 2018). “[I]t is not enough to simply show that the
comparators hold the same title and the same general responsibility as the plaintiff.” Evans,
936 F.3d at 196 (citing Spencer v. Virginia State Univ., 919 F.3d 199, 204 (4th Cir. 2019);
Wheatley v. Wicomico Cty., Maryland, 390 F.3d 328, 332–33 (4th Cir. 2004)). Indeed, the
plaintiff and comparators “must have virtually identical jobs.” Id. (citing Wheatley, at 333).
The two comparators Ms. Burnett presses on appeal worked in AstraZeneca’s
research and development division. Ms. Burnett worked in the commercial division from
2017 onward. J.A. 35. Commercial division project managers where Ms. Burnett worked
focus on marketing, but project managers in research and development manage clinical and
scientific studies. J.A. 31. Within the limitations period of March 2019 onward, Ms.
Burnett’s chosen comparators’ jobs were not comparable to hers.
Ms. Burnett does not dispute this. Instead, she argues that we should consider
evidence from 2016, when she worked in research and development. Appellant’s Br. at 27.
But “[t]he relevant question . . . is whether during the statutory time period, the plaintiff
5 USCA4 Appeal: 25-1029 Doc: 50 Filed: 03/20/2026 Pg: 6 of 6
was being paid less on account of her sex.” Brinkley-Obu v. Hughes Training, Inc., 36 F.3d
336, 345 (1994) (emphasis added). Even if Ms. Burnett’s evidence were persuasive, it
would have no bearing on whether she was paid less on account of her sex in 2019. She
cites no fact raising such an inference, and our review of the record reveals none. The
district court thus properly found no Equal Pay Act violation.
We dispense with oral argument because the facts and legal contentions are
adequately presented in the materials before us and argument would not aid our decision-
making process.

For the foregoing reasons, we affirm the judgment of the district court.
