Saturday and all RCA's on deck, except one RCA who had reason to be out. Auxie from RMPO (Senior Sub) is covering for that RCA. She is on rt 10, but asks her friend whose primary route is rt 14 if they can switch? The friend (rt 14) gives up her primary for the day to her friend. Is this ok? Is this something they can decide amongst themselves? Will the Regular carrier have a problem with the switcheroo if she finds out? What say Ye?
