The Equal Employment Opportunity Commission issues guidelines that define sexual harassment as illegal sex-based discrimination under Title VII. The guidelines define harassment as unwelcome sexual advances, requests for sexual favors, and other verbal or physical conduct of a sexual nature in three circumstances: when submission is made either explicitly or implicitly a condition of an individual’s employment; it is used as the basis for a hiring decision; or it has the purpose or effect of unreasonably interfering with an individual’s work performance or creating an intimidating, hostile or offensive working environment. Under the guidelines, employers who adopt anti-harassment policies and training are protected against some liability.
