Under the California Fair Employment & Housing Act, it is unlawful for an employer to discharge, expel, or otherwise retaliate against an employee for opposing harassment or discrimination on the basis of race, religion, color, national origin, ancestry, physical or mental disability, medical condition, marital status, sex, age or sexual orientation. It is unlawful to retaliate against an employee who opposes prohibited discrimination or harassment that is directed against her/him, or that is directed another employee. Furthermore, the employee need only have a reasonable and good faith belief that her/his complaint of discrimination or harassment was unlawful in order to prevail on a claim of retaliation. Federal law has similar prohibitions against discrimination, although its coverage is for the most part less comprehensive than California law.
