I am in Washington state. My husband worked enough at a company to earn a week of vacation time. He took the week off and was told he'd be paid for it on his hire-anniversary date (which would be 7 months later). He quit before the anniversary date. The company, on his anniversary, refused to give him the week's worth vacation pay because they felt they didn't have to do so. Is that legal or should we take them to small claims court?
