From what I've seen none of the total numbers changed in either COO. The bid process and who gets to bid the UE drivers first, did. Loosing terminals that are gaining UE drivers will have first crack at them.
All employees will be given a chance to bid out by seniority except for new hires on or after April 1,2008.
I found it interesting that if you move as a dock worker to a terminal that requires at CDL you will be trained to get it. If you don't hold a CDL and the proper endorsements at the time of the phone bid you can't bid on the UE. DS.
