What legitimate reasons are legitimate reasons for an adverse employment action?

Legitimate reasons under this standard are "reasons that are facially unrelated to prohibited bias, and which, if true, would thus preclude a finding of discrimination." Guz v. Bechtel Nat. Inc., 24 Cal.4th 317, 358, 8 P.3d 1089 (2000) (emphasis omitted). The employer "need not persuade the court that it was actually motivated by the proffered reasons." St. Mary's Honor Ctr. v. Hicks, 509 U.S. 502, 510 (1993) (quoting Texas Dep't of Cmty. Affairs v. Burdine, 450 U.S. 248, 254 (1981)); see also Muzquiz v. City of Emeryville, 79 Cal.App.4th 1106, 1117 (2000). However, "the defendant must clearly set forth, through the introduction of admissible evidence, the reasons for the" adverse employment action. Burdine, 450 U.S. at 255 (1981)).
