Hello I am an 8 year partime yard shifter (yard jockey) at UPS and I recently signed the bid list to be a part time feeder cover driver. But my wife has a baby on the way the end of this August and I plan on taking 3 weeks of FMLA to help my wife. My question is if I were to be called to go to feeder driver training or what not and I'm on leave at the moment will i lose my opportunity to move up. I know there aren't many areas that let part timers into feeders but all full time list were exhausted and I have the chance of a lifetime.
