If I were scheduled to work Christmas, and there was absolutely no work, my state's department of labor says the employer must pay me for 3 hours work. EVERYBODY should find their state's labor board website, read the rules and regs, then bookmark it for future reference. My state's site even has a handy form (with specific instructions on what to include) to send to them for any labor disputes such as a request for unpaid wages. Educate yourself people.
