I do the same, as I do not want to spend more time than necessary on lunch. Its the ones who take nothing, but yet put it in. That give their time away to UPS for free.I don't skip my paid breaks but I will only take a 5 min lunch squeezed between my 2 10 min breaks for a 25 min break. I only put a 5 minute lunch in the board unless I take more and they don't care I have been doing it for years and so has half my center.
I don't get more work than anyone else because orion tells them how long it going to take to deliver so many stops that day. I do get paid the same amount of OT I would have if I took my full lunch and I do get home earlier.
