New here and 1st post. I am a 12yr emplyee, been driving for the last 3. We recently bid routes and I got the worst one. I don't mind that, seniority is earned. But a 20 yr veteren took a route and he sucks. This route is all rural routes. It has gone out with 100 stops since I have been there. He gets to go out with around 70. He doesnt get in til 11pm sometimes. When he sucks, I have to either go get his pick ups or somebodys while they do his. What kind of a grieveance can I file.
