Doesn't matter who is the bargaining agent, it's literally going to take a strike to get a penny out of Franke's hands. They are there for one purpose and that's to turn around the company and take it public and cash out. Paying any work group is not in those plans. They will keep hiring by being better than a regional and showing an order book that keeps seniority moving.
The one good thing about going Alpa is that it will certainly make the inevitable merger and subsequent seniority integration a bit smoother.
