No work No money

I’ve started working at UPS last month and haven’t received any pay since then. For the past 2 weeks they told me not to come in to work because union guys “bumped my spot”. 3 weeks ago I talked to a supervisor about not being paid and he said I should have it by next week Thursday. Didn’t receive anything that Thursday. Talked to another supervisor and he said he checked the offices for my check and it wasn’t there.

I talked to another supervisor (the one that onboarded me) last week and she told me to text her my days and hours. I did and she left me on read. Sent her follow up text a couple days later and no response. Finally I decided to come in to work last Friday, even though they told me not to, to confront them. They wouldn’t let me get through the security entrance without being signed in. I called the supervisor that’s been ignoring me and she didn’t answer. I had to call another supervisor that was on their day off for them to call someone for me. After about 30 minutes of waiting someone came and told me I would need to wait until Monday for anything. That’s also when the supervisor that’s been ignoring me decided to text me saying she put all my hours in she’s waiting for payroll to send it.

It’s now Thursday and I doubt I’m going to see any check this week. I haven’t worked all this week and probably won’t for the remainder. What should I do?
