We won't lose overtime until we lose a good chunk of our bene's. Its cheaper for UPS to work you 9.5 hours a day, then hire 5 more drivers to give everyone 8 hour days. If we had no benefits, we would have no overtime. UPS doesn't have to pay into our pension for OT.
Lets say in one area there are 5 drivers with benefits all making 100k a year, thats 500,000. In order to get that area down to 8 hours, they will need to hire another driver, which drops everyone to 90k a year, which is 540,000 a year UPS pays. Obviously not exact, but why we have to work 9+ a day.
A sup once told me 9.2 hour days in the money spot.
I personally don't mind work 45 hours a week. More then that, I feel like my life is UPS. I average 47-48
