Under the California Fair Employment & Housing Act, it is unlawful for an employer to discriminate against an employee because of race, religion, color, national origin, ancestry, physical or mental disability, medical condition, marital status, sex, age or sexual orientation. It is also unlawful to discriminate against an employee because of her pregnancy. Discrimination claims may be proven by direct or circumstantial evidence by showing (a) the employee is a member of the protected class, (b) the employee was subjected to an adverse employment action (i.e., a termination, demotion, denied a promotion), and (c) the employee's protected status (i.e. race, religion, sex...) was a motivating reason for the adverse employment action. Federal law has similar prohibitions against discrimination, although its coverage is for the most part less comprehensive than California law.
