as defined by the Equal Employment Opportunity Commission, sexual harassment involves unwelcome sexual advances, requests for sexual favors, and other verbal or physical conduct of a sexual nature when submission to or rejection of this conduct explicitly or implicitly affects an individual's employment, unreasonably interferes with an individual's work performance, or creates an intimidating, hostile, or offensive work environment. There are two types: quid pro quo, a request for sexual favors that implies a trade (e.g. advancement on the job) and "hostile environment, a situation involving a sexually-charged workplace in which the employee is subjected to sexualized behavior and made to feel uncomfortable or threatened. Sexual harassment is a violation of Title VII of the 1964 Civil Rights Act (amended), and corporations and institutions of higher learning should all have and enforce policies prohibiting it.
