UPS really discourages transfers and only rarely allows it. Usually you have to quit and hope to get rehired at the new center. You might lose all company seniority but your years vested with the Teamster pension would be intact.
Although UPS might give you at least part of your seniority back it isn't guaranteed.
it's very dangerous to quit and hope to be rehired at another hub unless you are PT and losing very little time with UPS. I have heard several stories of long time UPS employees that believed management, the union even , and HR , and quit a hub , moved to another state and applied to the new hub and were told " we don't know what the heck you are talking about."
in those cases they were SOL. they did keep the time earned towards their pensions thru the Teamsters . then they could get another Teamster driving job thru ABF or Yellow or whoever with probably a weaker pension .
They tried to get me to quit. I would never ever quit. I kept trying and waited a very long time and finally succeeded but lost beaucoup seniority but it was worth it longterm. have a very respectable pension. no regrets.
