Sexual harassment is a form of Sex Discrimination that occurs in the workplace. Persons who are the victims of sexual harassment may sue under Title VII of the Civil Rights Act of 1964, which prohibits sex discrimination in the workplace. Such harrassment is defined as: Unwelcome sexual advances, requests for sexual favors, and other verbal or physical conduct of a sexual nature that tends to create a hostile or offensive work environment. The federal courts did not recognize sexual harassment as a form of sex discrimination until the 1970s, because the problem originally was perceived as isolated incidents of flirtation in the workplace. Employers are now aware that they can be sued by the victims of workplace sexual harassment.
