How about all of it.
They want PBS so that they can reduce staffing needs, get rid of what little soft pay there is, and reduce the costs associated with their grossly inefficient schedules (lots of wasted per diem and hotel rooms required to pay for these atrocious lines). I say "Let em have it!"
But in return we get
- to share the salaries and bonuses they would have spent on hiring and retaining pilots to adequately staff the airline with the current schedules
- the QoL gains we would all have gained due to hiring pushing up our relatively seniority
- the increase in flow rate that would have resulted from hiring to properly staff the current schedules
PBS can be mutually beneficial, for sure, but we can't let the company understate how much they'd get out of it. We deserve comparable gains, the above is just the start.
