There is this bathroom in our hub with a connected locker room in the back of it. When my shifts ended (sunrise ends about 8:30-9am) I made a habit of going into that locker room and changing into my motorcycle gear for the right home. I liked changing there because the place is clean and for the most part vacant at that time of day. I would go in there and change my pants and get my jacket on and boots and get all my stuff packed away before leaving. Made conversation with some feeder drivers who were mostly good guys working hard to make ends meet just like me. Anyway last Monday I am in the locker room changing and a feeder driver comes through. He is a guy I have always seen around but one that never responded to my good mornings or hellos, no big deal the guy works hard and doesn't want to say hi for whatever reason. He comes into the locker room while I am changing and all of a sudden asks if I work feeder. I tell him no of course not I work on the sort isle. He then tells me I have no business in this locker room and that he is going to report me to management. I tell him that I was unaware I wasn't supposed to be in there and that I would not come in there again, and that I was sorry. He responds by telling me that's what they all say, and that he would take care of it. I said he would not see me in there again. That was a promise I would honor too. So I migrated to the other side of the building far away from where I work and changed in there in the dirty stall. I wasn't happy in there but I was doing what I had to do. Then this morning halfway through my shift I get called from my work area and go to see a full time supervisor. He tells me that it was reported that I was using facilities that I wasn't authorized to use and that I was going to be disciplined for it. He then tells me that I will be suspended for two days for this offense. I was floored by this. I told him that I had not returned to that locker room after being told not to come there. He didn't care. I got a shop steward involved and even though he fought as best he could the suspension was upheld and I was told to leave the building. Now I am out of work for two days and off to no end. Any ideas on what to do? I regret ever going in that locker room now but there was nothing that made it apparent to me that the room was off limits to me. No signs, nothing. So any advice on what to do? Should I just take it ******and move on?
