I have been with UPS for a year and a half. I am on the preload but have never signed a bid sheet because i figured it would never get down to me. A fellow co-worker who has 6 months more seniority is number 50 on the list. Suddenly today someone with far less seniority then me is taking the test to become a cover driver. Do the Sups have to follow seniority on the bid sheet? If so can i file a valid greivence even though my name was not on the bid sheet?
