If you can remember back a few years and ask "why did UA park all the B-737's?
The answer was relaxation of scope.
That cost 1400 mainline pilot jobs.
If we relax scope further that will have a similar affect.
If CO pilots give up on scope that is an immediate 800 pilots that will be gone, or be let go through attrition and those jobs will be replaced by RJ pilots working for one quarter of what we earn in total cockpit compensation.
If the UA and CO pilots give it up that will be about 1200 pilot jobs gone forever.
If we give up more international flying to Aer Lingus......well, you get the point.
A 30 percent pay raise don't do you any good if you aren't employed to earn it. Voting yes to relaxing scope is voting yes to management outsourcing your job.
