Like Re-Raise said, once you say it's ok to wheel and deal after the bid where does it end? Bidding a route just to switch with a lower seniority guy later so that someone between you on the list doesn't get it? I've seen that tried. What if a senior driver bid all the summer weeks and then offered to "trade" them for a $100 a piece? Would that be ok? I know you worked at a small building but it's unreal the things drivers will do to try and game the system. The simplest solution is to not allow trading. Seniority gives you the right to bid, but once you make your decision that should be it.
