The issue I am thinking of goes more like this - Skywest finally decides to go union and votes in Teamsters. After drawn out and unsuccessful attempts to negotiate a contact the Skywest pilots, represented by Teamsters, go on strike. ALPA then decides it is okay for ExpressJet (a subsidiary of Skywest represented by ALPA pilots) to go ahead and take over some or all of the Skywest flying in an attempt to weaken the Teamsters union. Skywest management gets the benefit of having another of their subsidiaries take over the flying and thus lessen the pressure of the strike. In the eyes of ALPA the Expressjet pilots would not be scabs, but in the eyes of Teamsters they would be. Who wins out? Are the Expressjet pilots scabs or not?

Again, an unlikely scenario, but interesting to ponder.
