I would like to switch my 3rd choice route with another RCA that agrees to switch with me. The RCA's above us do not want to change anything on their routes. We are next to each other on seniority. Can we just ask to switch and have it be done? (The formal process of asking the senior RCA's would have to happen first - I realize this). Or does there have to be another round robin? Where can I find information that the matrix will allow this? My supervisor is not against this switch and the regular on the route is game as well. Management just does not want to go against the matrix and I understand that.
