A challenged employment action is adverse for the purposes of a claim for retaliation under Title VII if “a reasonable employee would have found [it] materially adverse.” Mickelson, 460 F.3d at 1315. As the Supreme Court put it in Burlington Northern & Santa Fe Ry. v. White, — U.S. —, 126 S.Ct. 2405, 165 L.Ed.2d 345 (2006), an employer’s action is adverse under Title VII if it “well might have ‘dissuaded a reasonable worker from making or supporting a charge of discrimination.’ ” Id. at 2415 (quoting Rochon v. Gonzales, 438 F.3d 1211, 1219 (D.C.Cir.2006)). Applying this standard, the Court held that a jury could reasonably find a material adverse action under Title VII where an employee was involuntarily transferred from a job as a railroad forklift operator to a less desirable position as a track laborer, even though the duties of both positions were similar. Id. at 2416-18.
After Burlington Northern we have continued to examine claims of adverse action through a “case-by-case approach, examining the unique factors relevant to the situation at hand.” Sanchez v. Denver Pub. Sch., 164 F.3d 527, 532 (10th Cir.1998) (internal quotations and citations omitted). The materiality of a claimed adverse action is to be determined objectively; “petty slights, minor annoyances, and simple lack of good manners” will not deter “a reasonable worker from making or supporting a charge of discrimination.” 126 S.Ct. at 2415. The Supreme Court further noted, however, that “[c]ontext matters.” Id.
In a recent case applying the Burlington Northern standard, we found that the “prospect of losing wages, benefits, and ultimately a job” would dissuade a reasonable worker from supporting a charge of discrimination. Mickelson, 460 F.3d at 1316. Even prior to Burlington Northern, we found adverse action if it “constitutes a significant change in employment status, such as hiring, firing, failing to promote, reassignment with significantly different [job] responsibilities, or a decision causing a significant change in benefits.” Stinnett v. Safeway, Inc., 337 F.3d 1213, 1217 (10th Cir.2003) (internal citations and quotations omitted). Examples of adverse action from our pre-Burlington Northern cases include: (1) the transfer of an experienced female police detective to a position in the police academy after the detective filed an EEOC complaint due to “concern for her safety,” Duncan v. Mgr., Dep’t of Safety, City & County of Denver, 397 F.3d 1300, 1307 (10th Cir.2005); (2) issuing written reprimands where those reprimands made it more likely that a complaining employee could be fired, Roberts v. Roadway Express, 149 F.3d 1098, 1104 (10th Cir.1998); and (3) management’s goading of an employee’s co-workers into filing a false criminal complaint against him, Berry v. Stevinson Chevrolet, 74 F.3d 980, 986-87 (10th Cir.1996).
Since McGowan’s termination was obviously an adverse action, we turn to her claim that the City also took materially adverse action by (1) failing to assign her to a day shift, and (2) sanctioning workplace harassment by her co-workers.
1. Eligibility for Day Shift
McGowan contends the failure to reassign her to the day shift is a materially adverse action. The district court disagreed, finding her preference for the day shift “a mere inconvenience or an alteration of job responsibilities” that was not actionable, relying on Sanchez v. Denver Pub. Sch., supra, 164 F.3d at 532 (holding that teacher transfer not adverse).
The question, then, in the wake of Burlington Northern, is whether a reasonable person would be deterred from making or
