No, the same class and craft till 2006 at US, still on the same CBA till this day.
Correct on the CBA, not according to the NMB if there was an election for representation.
The NMB does not car if they mix different class and craft on a CBA. we could all be on one document, fleets, maint, stock clerks, gate agents, pilots, Flight attendants, the NMB does not care but each of those groups votes seperately if there is a representation vote.
So, yes Stores and Maint can be the same contract group at US, but they are not the same class and craft as defined by the CBA unless Stores does work that fits the descriptions of the mechanics class and craft.
We hear the IBT is collecting cards over at US from mechanics, are they collecting them from Stores?
