That would never fly where I am. If you're a bid driver you cannot be forced off unless it's cut. They don't even attempt it. The last I remember them moving a bid driver was to a 24 footer route and that driver was the only one that knew it. Did it for 2 days and told them that's it. Find someone else. Not my problem. Thats was years ago
Would think they could push it somehow on the idea it is very unsafe. Putting a driver in unfamiliar situations. Repetition is a key part of safety imo, much more than regurgitating that their safety literature.
