I am a PT loader, and if I am asked to drive during peak season (my center has a lot of recent loaders that are now drivers). Anyways, if I become a driver after Oct. 1st, do I lose my PT seniority? Or would I still have a PT seniority date and a FT or Driver Seniority date? Then when peak is over, would I be able to go back to PT loader? How does that work?
