Nothing at all wrong with it.
Unless of course you consider....
its against company policy, and teamster policy.
Well Hell, thats one rule that isnt enforced as it makes the preload look better, coz you are working for free, and none of your time is figured into anything.
When I was on the preload I loved it, except the fact that they were taking away my work, which is why UPS didnt think we needed extra help coz hey, we got 15 drivers giving the preload 7.5 hours of their time to get the job done. But at that time I didnt realize the big picture.
I see the pros and cons and we have drivers at the am meeting drenched. So its not like they are doing it secretively.
I just think its wrong. Do they call and say they need you? No you just think to make your life easier, youll just give a little more, and what do you get in return, a better day? Nope more work.
Knock yourselves out, I wont do it.
