To the OP, I would say this: you better be consistent about the over 70’s. If you need help, call for help, as the contract stipulates.
But don’t just do it when you get a wild hair, or when you’re

. You want management to know when you request help, you mean business.
As others have pointed out, taking your lunch at the end of the day, is a red flag, and against the language of the contract.
This leaves me with the suspicion that you could be a “shortcut” driver, and if file as many grievances as you say you do, you could find yourself in trouble.
You can’t just decide which methods you will or won’t follow; otherwise you won’t be standing on firm ground. UPS’s methods are a driver’s best friend.
