Although sexual harassment in the workplace is illegal, it often goes unreported. This study employs causal evidence to evaluate one deterrent to reporting: bias against women known to be sexual harassment targets. I theorize about the form this bias takes and test the argument with a national survey experiment run in five waves from October 2017 to February 2018, where participants were asked to propose employment outcomes for an employee with one of four harassment experiences. Participants were less likely to recommend a woman for promotion if she self-reported sexual harassment relative to otherwise identical women who experienced nonsexual harassment or whose sexual harassment was reported by a coworker. The woman who self-reported sexual harassment experienced normative discrimination: that is, the promotion bias was significantly mediated by perceptions that she was less moral, warm, and socially skilled than the woman whose coworker reported her sexual harassment. These results indicate that women may hesitate to report sexual harassment because they rightly perceive that doing so could cause them to experience bias. Yet they also suggest that bias can be avoided if a bystander reports the harassment. Finally, exploratory analyses suggest that in the wake of #MeToo this bias may be fading.
