I was hired by ups for a part time feeder unloader position. I was told there would be a 30 day trial period. On day 30 at the days end i was told I was being let go By the head supervisor. I tried to argue and plead my case but my times were just slightly too slow. He then asked me if I still wanted to take my DOKs or if I was too upset. I said I would and passed. The head supervisor then got a union steward in. He began to give me a 10 more day trial period where I still don't qualify for the union. We all signed it the steward the head supervisor and I. I left the office and ran into a different union steward who informed me what the head supervisor did is not in the contract and gave me a form to join the union. He said if the supervisor tries to fire me come to him and he will protect my job. I was just wondering what I should do? Or whose is telling the truth. Do I qualify for the union or am I still in my trial period where I can be let go?
