Hey everyone, had a question- So being in school as well as working i've generally been the guy to voluntarily go home if they needed to send someone home. I've been a loader almost 3 years now, and recently completed the application for becoming a PT sup (apparently now its a waiting game). Lately though, my PT Sup has been asking me if I want the night off before I even come in, which I don't mind the option and it saves me the drive if I would prefer the night off. Anyway, I got a text from him today telling me to take the night off. I replied that i'd like to get my hours in. He replied ok, start time is 5:40, be on time. Then about 25 mins later I get a text saying (quote) "Hey ur bottom seniority and everybody coming in so (full time sup) told me to tell you to stay home". Last night he offered me the night off through a text before start, I voluntarily agreed, and then he texted me around 7:15 asking if I could come in. Being in a potential Supervisor spot, I figured i'd go in to try and get some extra points, so I texted my Sup that i'd be in in around x amount of time, I rushed home (I was out fishing), got my work clothes on, and when I had just finished tying my boots I got a text that said "oh, nvm then." This has put me in a weird spot. I'm not really sure how much influence my PT/FT Sups have over the application for me to become a PT Sup, and I figure going in and demanding my guarantee and getting a union steward wouldn't put me on good terms with them. My PT Sup can act like a child at times, he'll turn on you faster than you can blink, and its pretty common for him to make rash decisions on the spot, for instance a little while ago we had a Pickoff call in because he had tickets to a game, and my furious PT Sup then went around asking people if they wanted to be the new Pickoff permanently, I said yes and after verifying numerous times that he was serious about it, and it was a "for sure" deal (our management can be a bunch of windbags) and he said "alright, we'll get you up there monday." Monday came, and the guy who called in was up on the pickoff, I asked him about it and he said something along the lines of "I had a problem and I fixed it." I said "I thought I was gonna be up there", and he replied "Well, I thought I was going to need you, but now I don't." TL;DR- So basically I don't want my PT/FT Sup or any other management going into my supervisor app and putting down something negative because I demanded my guarantee (which I definitely wouldn't put past my management if they had the chance). My question is, would they be able to do such a thing? Any info would be greatly appreciated, thanks!
