Washington Revised Code Title 49. Labor Regulations § 49.60.180. Unfair practices of employers

(1) To refuse to hire any person because of age, sex, marital status, sexual orientation, race, creed, color, national origin, citizenship or immigration status, honorably discharged veteran or military status, or the presence of any sensory, mental, or physical disability or the use of a trained dog guide or service animal by a person with a disability, unless based upon a bona fide occupational qualification: PROVIDED, That the prohibition against discrimination because of such disability shall not apply if the particular disability prevents the proper performance of the particular worker involved: PROVIDED, That this section shall not be construed to require an employer to establish employment goals or quotas based on sexual orientation.

(2) To discharge or bar any person from employment because of age, sex, marital status, sexual orientation, race, creed, color, national origin, citizenship or immigration status, honorably discharged veteran or military status, or the presence of any sensory, mental, or physical disability or the use of a trained dog guide or service animal by a person with a disability.
