Last few week we've been short handed and I've been scheduled mass overtime work hires new people and proceeds to drop me down to under 40 hrs when I tell my boss I need at least 48 hrs to make ends meet im told not to be selfish and that I will get 40 and be happy, so today I told them I had to pick up shifts at a different company I was told that being unavailable on certain days now is unacceptable if I wanna move up? So what they expect me to do?
