In regards to workplace sexual harassment and assault, survivors may have both civil and criminal legal remedies available to them. Sexual harassment falls under Federal and Washington State employment discrimination laws. There are two forms of sexual harassment in employment which are illegal: 1) hostile work environment and 2) quid pro quo (See resources below for specifics about these types of claims).
Title VII of the Civil Rights Act of 1964 makes employers liable to prevent and stop sexual harassment of employees. Under Title VII, covered employers must: (1) take reasonable care to prevent sexual harassment; (2) take reasonable care to promptly correct sexual harassment that has occurred. Before an employer can be legally responsible for taking reasonable care to correct sexual harassment, the employer must be aware that the harassment has occurred.
RCW 49.60 is Washington State's "law against discrimination," which includes sexual harassment as a form of sex discrimination in employment.
