Well this sucks. First of all I want to start off by saying this was my favorite place to work at and the manager/GM was one of the best I've had. I loved the environment and workplace, did my job correctly, and never had any complications or problems.
When summer first started everyone's hours were being cut to accommodate the highschool students (I am as well but was working full-time basically previously) so it was whatever then. Til one week I didn't get scheduled, whatever I needed time off and that wasn't abnormal for people to not be scheduled. Well after that week, I wasn't scheduled once again. At the end of the week my accounts were deactivated and I shot the GM a call. He explained he had no idea what happened and that I wasn't fired, he said he'd give me a call in a few days to let me know. I've texted him, left him voicemails, talked to coworkers and nobody knows anything and I'm guessing I was ghosted.
I've gotten my last pay but what steps should I take next? This counts as wrongful termination if I'm correct, right? I'm (17, State: AZ) and am just beyond confused. Can I file unemployment while I look for a job? Should I do anything else regarding his employment?
