When I was living in Washington, the company policy was you could not put in for vacation before quitting. Your vacation would be cashed out. So being the naive moron I am, I did as instructed and waited for my check cashing me out for 3 weeks of accrued vacation. The check came a month later for $0. I called about the obvious mistake, and they matter-of-factly told me that Washington doesn't require them to compensate, so I was cashed out for $0.
