discrimination, racial discrimination, and retaliation when it terminated Slack’s

colleagues. We have jurisdiction pursuant to 28 U.S.C. § 1291. We review a
district court’s summary judgment de novo, Carver v. Molder, 606 F.3d 690, 695
(9th Cir. 2010), and we affirm.
The district court did not err in granting summary judgment to United on
Slack’s gender discrimination claim. Slack failed to prove a prima facie case of
gender discrimination because he failed to provide evidence that similarly situated
employees not in his protected class were treated more favorably than he was.
Godwin v. Hunt Wesson, Inc., 150 F.3d 1217, 1220 (9th Cir. 2020). Even if
Slack’s contention on this element—that the female colleagues who accused him
of sexual harassment in fact sexually harassed him but were not terminated—was
supported by evidence, the female colleagues are not similarly situated to Slack
because Slack’s conduct gave rise to a formal sexual harassment complaint while
the female colleagues’ alleged conduct was raised only “defensively in the context
of the company’s investigations.” See Hawn v. Executive Mgmt., Inc., 615 F.3d
1151, 1160–61 (9th Cir. 2010). Additionally, even if Slack had alleged his prima
facie case, Slack failed to provide evidence that United’s proffered legitimate non-
discriminatory reason for his termination—Slack’s violation of United’s sexual
harassment policy—was pretext for gender discrimination. Vasquez v. Cnty. of Los
Angeles, 349 F.3d 634, 640 (9th Cir. 2003).
The district court did not err in granting summary judgment to United on
2
Slack’s retaliation claim. Slack did not prove that he engaged in a protected
activity. Brooks v. City of San Mateo, 229 F.3d 917, 928 (9th Cir. 2000). His
contentions that he challenged the “harassment culture” at United or that other
employees sexually harassed him were unsupported by evidence other than his
own statements. Even if they were supported, he again failed to provide evidence
that United’s termination of him for violating its sexual harassment policy was
pretextual.
The district court did not err in granting summary judgment to United on
Slack’s racial discrimination claim under 42 U.S.C. § 1981. As with his gender
discrimination claim, he failed to make out a prima facie case because he failed to
provide evidence that similarly situated employees outside his race were treated
more favorably than he was. Zeinali v. Raytheon Co., 636 F.3d 544, 552 (9th Cir.
2011). Additionally, Slack failed to prove that, “but for race, [he] would not have
suffered the loss of a legally protected right.” Comcast Corp. v. Nat’l Ass’n of Afr.
Am.-Owned Media, 140 S. Ct. 1009, 1019 (2020).
AFFIRMED.
