Then I guess we need to change it in the contract where they can hire 10/1 or 15/1....
I must be misunderstanding. I agree, A driver just can't come off the street and jump over people.
In cases that I know of, they put up a bid list for package to come over to feeder. NO ONE signed it. Then they put up the bid list in the building for part timers. NO ONE signed it.
So they hired off the street. That sounds OK. That is how I was hired off the street.
Maybe that is the case here. He's not stepping on any toes but the people who started with the company at the very bottom think they are better than this guy for some reason.
He hasn't "paid his dues" in their eyes. It doesn't matter that he probably worked non union jobs for

pay and no benefits for 10-15-20 years.
Now , he hit the lottery and some people are just gonna be jerks about it .
I have always been very grateful that I worked my butt off for almost 20 years before UPS. Always had much more appreciation for this job than the guys and gals that started here right after high school and never knew anything else.
