I am a PT Feeder Shifter working in the HUb. Im certified to drive air and on occasion asked to deliever ground. My primary job feeder dept. says I could no long be borrowed while Im working as a shifter, but they as a department (feeder) borrow combo & Pt employee's straight from the hub everyday during the hub employees current job. How can they do one thing and not allow me to get borrowed by package who pay a significant amount more hourly. Word is if they do it to/for another emoloyee that they need to honor it for every other employee after. Any thoughts?
