Listen, if you're not getting paid for your hours, it will only go on as long as you allow it. If you don't want to work more hours, don't. Tell them you want your money or you're leaving at 5.5 unless you get a day off for all that time your owed if they're not paying you. Guarantee you'll be fine after that. No one should work for free. No one. If something happens to you while you're "not working" its on you, not UPS because your official records will say you were out whenever your 5.5 was up. This is a serious issue, if it goes on, talk to your district HR manager, guaranteed its fixed soon after if not immediately after your talk.
Of course they expect you to work. Do you really think most human beings are able to work day in day out at 250+ pph and never get run down? this is where you come in because though they say you'll be sent help, you and I both know that its never coming unless one of your fellow PT supes goes down early and sends some to you. My area is averaging 1350pcs (per set of package cars, some heavier, some lighter) and we're starting @ 330....BS with a 8:30 projected wrap time. I understand we can't start earlier because the night sort is still running...but we never had that problem until last year. Its (peak) just getting progressively worse each year, you'd think we'd get better at it. We ran out of drivers today...I kid you not. They were asking sat air drivers to run stuff. Doesn't seem too light around these ways, not nearly as light as they warned us it would be (not that I believed it).
I worked all 3 days this week, I'm not proud of it, but I'll admit it. I'm not going to lie and say I didn't but they get mad when you put yourself in the staffing and submit a timecard which shows you had no union employee and YOU did the work. One particular day they took people from another supes area to cover a different area (which had employees not show up) for 30 min and then said they were keeping them! That left this particular supe with two uncovered sets of package cars (its happened to me before too) just so they could cover another area. Robbing peter to pay paul basically. They wonder why supes get frustrated and are lashing out now, we're set up to fail by our own superiors and then get kicked in the face when it comes time to pay us for the extra work (not at my building so far, but I'm told it has happened in the past).
