My unloader has poor attendance. We have a new ft sup and a new preload manager. The ft sup came up to my unloader and was giving him a verbal warning. In front of me. I had told him earlier to make sure he asked for the steward, so he did. He was told one wasn't needed for a verbal warning. Then asked him to sign a paper stating he received the warning. Glanced over to me and i shook my head no. So he refused. So my question is, a shop steward should be present for ALL forms of discipline, correct?
