I am an Air shuttle driver MON-FRI night and I also drive Saturday morning air. We have two drivers in our center that run every saturday. I usually average 3-5 hrs on Sat. while the other driver does the same plus an extra 2 hrs to go bring our Pickups to the main hub. I just recieved news that a cover driver that has not been getting hours will now be added as a third driver on SAT to cut everyones hours under 5 hrs. He claims he can bump me off my route and run it and that I have to come in in the afternoon and get less hours by doing the hub run. He has seniority over me, but from what I understand he is probably still considered a cover driver. Can he even do this??? Am I wrong in thinking that he would have to wait on a bid sheet, then bid Sat air, THEN he can bump me?
