In the first study measuring sexual harassment experiences of academic library employees at a single institution, we conducted a census of 1,610 nonstudent employees at the 10-campus University of California Libraries system. This anonymous online survey measured how sexual harassment was experienced and observed in terms of behaviors, exhibitors, reporting and disclosure, institutional support and betrayal, and recommendations for future actions. Out of 579 respondents, 54% experienced and/or observed sexual harassment at work. Respondents recommended training, workplace culture change, support from leadership, and clear reporting processes in order to address sexual harassment at University of California Libraries.
