Disparate Treatment: A Closer Look
STEP 1: The "plaintiff bears the initial burden of establishing a prima facie case of discrimination, which creates a presumption of discrimination." Scrivener v. Clark College, 181 Wn.2d 439, 446, 334 P.3d 541, (2014) (citing, Riehl, 152 Wn.2d at 149-50; Kastanis v. Educ. Emps. Credit Union, 122 Wn.2d 483, 490, 859 P.2d 26, 865 P.2d 507 (1993)) (internal citations and quotation marks omitted) (emphasis added).
STEP 2: "[T]he burden shifts to the defendant, who must articulate a legitimate, nondiscriminatory reason for the adverse employment action." Mikkelsen v. Public Utility District No. 1 of Kittitas County, 189 Wn.2d 516, 527 (Wash. 2017) (internal citations and quotation marks omitted) (emphasis added).
STEP 3: "[I]f the defendant meets this burden, the plaintiff must produce sufficient evidence showing that the defendant's alleged nondiscriminatory reason for the adverse employment action was a pretext." Id. (internal citations omitted) (emphasis & hyperlink added).

"To esablish a prima facie disparate treatment case, a plaintiff must show that his employer simply treats some people less favorably than others because of their protected status." Id. (citing Johnson v. Dep't of Soc. & Health servs., 80 Wn.App. 212, 226, 907 P.2d 1223 (1996)) (hyperlink added).

For example, take our disparate treatment tests based on (1) termination of employment; and (2) adverse employment action:
