Lies about time off - Sales Associate/Cashier bei Target: Mitarbeiterbewertung

I worked weeks with no days off and doubles on both thanksgiving, black friday, and the day after. I was told i'd get christmas day off if i worked on christmas eve morning. they scheduled me anyways and i told them i had already booked flights home. they said that was my fault and i have to work christmas and day after christmas because someone quit.
