Ok so I need a little clarification... You are a preloader, did I see in Florida? What is your seniority date? If you have seniority and are getting laid off and someone with less seniority works... FILE A GRIEVANCE! This is the process, if a driver bumps back he displaces 2 PT employees. They can ask you to take the day but if you are not the bottom guy they CAN NOT force you to go or stay home without forcing EVERYONE under you. So if there are 10 people under you on the seniority list they would have to lay off 11 to force you. If they do that you have no grounds, if they work someone with less seniority file a grievance for the hours that employee worked. The company WILL pay that one.
