I hope I can find help here. I live in Chicago. I was just fired today from a manufacturing plant. It’s a union shop that doesn’t have a union rep on-site. The managers fire anyone at will. Well today I was let go. Under the union contract with this site, entry level employees can be let go at any time during their probation period. This was me. They did not want to provide a reason when my supervisor and manager had me in the room. Can they fire me just cause the contract allows them to? Is there a state law that I can use against them?
