I currently work in local sort and have been for over a year now but I worked this season as a driver and now the manager told me that I can either go to preload or not work for UPS anymore. I haven't gotten a hold of my union steward yet, so I thought I'd ask here first. Are they allowed to make me change jobs like this since they are completely different shifts? When I moved to local sort, they asked if I would be willing to do it. Preload will mess with my other full time job along with my home life.
