Where in the contract does it say someone is protected except in cases where another driver bumps you..." There are many reasons why management has to change their plans, some of them being valid. If you happen to be a two-year driver who knows just about all of your center's delivery area-I was in this category in my previous center-you may find yourself moved last minute because no one else knows the route someone just called out on. It isn't management's fault, but the contract assures you that you won't be caught in a bind due to this. If a driver who has been doing something else all week decides he'd rather take it easy on Friday and bump you, again, you are being re-assigned from your given assignment from that week. Why you were moved from that assignment is irrelevant, and the contract makes no concessions in that regard.
