WA LAW AGAINST DISCRIMINATION
Under WLAD, it is an unfair practice, with very few exceptions, for an employer to refuse to hire any person, to discharge or bar any person from employment, or to discriminate against any person in compensation or in other terms and conditions of employment because of age, sex, marital status, sexual orientation, race, creed, color, national origin, 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.
DEFINITION OF “NATIONAL ORIGIN”
“National origin” includes “ancestry.”
