When a business model's success depends substantially on low-wages, and thousands of pilots vote "Yes" to those wages by accepting jobs working within that model, no union will later be able to significantly change the force or fact of this low-wage dependency.
Once upon a time NetJets was considered a PFT suck-it-up-financially, jet time-building stepping stone to a lucrative job at the majors when they were hiring in record numbers. That the frac-to-major route has suddenly shut down doesn't change anything about the frac business model, only the expectations and realization of harsh realities of those working within it, and the labor market is flooded.
The moral of the story should be obvious; don't take a job that sucks, know the business you work in and don't pretend it's something it's not, and don't believe the promises of those lacking foresight who did, even if there's a lot of 'em.
