Ok. Got it. Thx for taking the time to explain the fleet side as it was slightly confusing. If I were a gambling man I would have to put my $$$ on the DOH/classification as the winner since the majority is in fleet in this asso.No, not any classification. This is solely about going from Clerk/Agent to Crew Chief/Lead in Fleet. There is no separation like there is in Maintenance, therefore this doesn't affect Fleet.
On your second point. If I'm a Fleet Service Clerk my Company (DOH) and my Occupational (Classification) is the same date. If I take a Crew Chief/Lead both of my seniority dates would still be same.
