Dave, I am not UPS, but I too have the same 50.31 as the top rate. I have also heard of 53 and some change but do not know which one is correct. I do know the UPS mechanics are currently at the table nego a new contract shooting for 60 per hour. UPS is soon to be at a new contract as their contract was amendable at around the same time ours was. Been very, very quiet from the UPS boys and have been wandering why so quiet. Good luck geting an answer to your question from a UPS mechanic.
