My question involves labor and employment law for the state of: MD
Warning for lateness I mean. Basically my manager told the District manager that I have lateness issues and I'm on conduct warning and couldn't be transfered. He told him he has documents showing that. I'm not sure what kind of documents. He never had me sign any formal documentation or anything-which I told the DM. He told me I don't have to sign anything because of the "documents" they have. So my question is how can they prove it, if I was never given a written warning which would show that did warn me?
