Strong sexual harassment cases rely on documented incidents, witness testimony, and established patterns of inappropriate behavior. Save all emails, text messages, photos, voicemails, and written communications related to the harassment. Document each incident immediately with specific dates, times, locations, and witness names. Report harassment to HR or supervisors in writing when safe to do so, keeping copies of all reports and responses. Witness statements from coworkers who observed or heard harassment are extremely valuable. Even without perfect documentation, don’t let evidence concerns prevent you from seeking legal help – we know how to build compelling cases using available proof and can often uncover additional evidence through legal discovery processes.
