About a month ago the most senior sub in my office who has been holding down a K route (des. 74) moved up to an Auxiliary route and chose the 5 and 1 option (non-formula office) so she could take the auxiliary route in case the regular comes back and run the K route 6 days a week until then. She was going to run the K route for 90 days until she is forced to choose between the routes and I believe she was planning on choosing the K route. Although, on the day everybody moved up her name stayed on the K route as designation 74 and now my name is on the auxiliary route as the main carrier as designation 78. Did I get the auxiliary route because she was already in leave earning status? I don't think my relatively new supervisor or union steward really knows what happened or what needs to happen.
