In the United States, Title VII prohibits two kinds of sexual harassment: quid pro quo and hostile work environment. When a quid pro quo case is proven, employers automatically are liable. Employers are liable only under certain circumstances when hostile work environment is proven. Quid pro quo cases require that the unwelcome sexual demand on the employee be made by someone with the ability to grant or deny an employee some benefit. Also, there must be a link between the demand for sex and the granting or denial of the benefit. Hostile work environment cases must involve pervasive, unwelcome sexually charged behavior that is directed toward an employee by someone in the workplace.
