I started this new job this week and since starting my schedule has changed 2-3 times. I received a call two days ago saying that I was supposed to work today. When I showed up I noticed I wasn’t put on the schedule so I thought there was some scheduling issue or a misunderstanding going on. I asked my supervisor about it and she said I could go home if I wanted so I did. I received a call from the owner of the place asking why I didn’t stay for my shift, that a manager had called and told me to come in for today. She seemed upset and like she was going to fire me. I feel like I’m fucking this up and I don’t know if it’s my fault or not.
