working for UPS on the graond side will not help you. I have asked this before and the only thing it might do is impress the person conducting you pilot interview, if and when you get it, but no extra points.
The ground and air side of things here at UPS are not as harmonious as you may think. I know that many of the mid level managers resent the pilots. You have to be careful, UPS is a difficult place to work and on the ground side, the possibilities of getting a negitive review are more likely than you may think. Not saying you would get one, but if you did, you'll never get hired here with a neg review in your file...
I had a friend who befriended a ground manager and he (the ground manager)went out of his way to help my buddy get hired here. There are always positive stories out there and it really depends on your personality and who your boss is on the ground side...
I hope this helps.
