Its not about bitterness or anything like that. Its about operating in compliance with the agreed upon contract.
Example, people that work their vacations. "Im just doing it to make extra money, i need it right now, there nothing to do anyway, yada yada yada." Great, now next year, ups is gonna look at the numbers and say, well we handled x amount of volume last year, we only need to hire this many more drivers. In reality, they should have hired more last year, but
s kept bailing them out by working vacations, so we essentially eliminated that many hourly positions. Eliminated money going into the pension fund, healthcare fund, etc...
