Before I go on a short rant, my specific question is this: How far back in history can management go to discipline you? Since I have been employed as a preloader at UPS (~1.5 years), I have been late maybe 10 times, 80% of which are probably about a minute late. But yes, 1 minute late is still a minute late and it counts, I understand. If management wanted to harass me with disciplinary action, can they do so regarding events from months ago? Why am I asking this? Just to better understand what may happen if I do what I may be forced to do in the future. A few days ago, I was finishing up my last truck. It was late, past 9am. Most drivers were already gone, and I was the last preloader in the building. This is fairly typical on specific days, as this mall route that I load requires a lot of stacking out. Time commit stops that have to be loaded down the center, at the very end of the day. My belt sup comes up and tells me that I need to get off the clock, that he will finish the rest. This directive came from the shift manager. I was almost done anyway, and I didn't want to choose that battle, on that day, so I left. I clocked out at 9:12. The driver who was covering the route that day made a big stink about it, and apparently off the preload manager. He was saying how he could file a grievance on it himself, etc. The next day, my full time sup comes to me at the end of the sort and tells me that I need to be off the clock before 9. Again, a directive from the preload manager. Ever since that day, I have actually managed to be done before 9. So, I haven't had to deal with this yet. But... this isn't going to last forever. The next time that route gets hit really hard again, ...I'm going to be there for as long as it takes to finish. If I am approached about getting off the clock, and I find out that a sup finished my work, I will tell them ahead of time that I will file a grievance. This isn't even so much about them "stealing money" from me, or however some people choose to think about it. I put forth an effort to load my routes properly every day. It may take me longer to bulk out than others, but that has to do with the quantity of bulk stops, and the fact that I don't just pile crap in whichever way it will fit. I load them in a decent order, so as not to block earlier stops, and I try to wall up the middle in a way where the whole mess doesn't collapse as soon as the truck leaves. This takes a little bit more thought and time. So, I do this for the drivers, for the company, and I'm told to get off the clock? That feels to me like a kick in the face, and I won't let it slide again. I understand the bs that could follow after filing a grievance like this. So I'm just trying to mentally prepare for and go through the possibilities. Hence, the question.
