I changed my availability and it was accepted and supposed to be in the system last week but I still keep getting scheduled for shifts outside of it. I spoke to HR about it and she said she would fix it but I'm looking now and it's still on the schedule for tomorrow. I've called everyday but they are never in their office or when I'm working. So now I don't know what to do...there's no way from me to work that shift tomorrow so what do I do?
