Won't you have to convince the union to do this change? They seem particularly intractable from my outsider's POV. If they accept culpability here and make one change, maybe they would consider that as bending and inviting future concessions. It's a shame that overall efficiency and rider satisfaction count for much less to the union than their own politics.
