I put my name on a bid sheet along with about six other people. I have the highest seniority on the list, the next person below me is a whole year behind me on the seniority list. When I wrote my seniority date down apparently I put the wrong month so my supervisor is telling me that I do not get the bid even though I have the highest seniority because I put down the wrong seniority date. Can they do that? At first I thought he was just joking, i laughed. But he said "no im dead serious you need to know what your seniority date is".
