You have that exactly right ship, the only thing the Polar MEC wants is to make the company adhere to the scope clause, nothing more, nothing less. Unfortunately, when you feed from the bottom of the trough, someone is going to get hurt, and therein lies the crux of the problem. I am sure that both MEC's don't want to see anyone lose their job, but it is going to happen. However, each MEC has the responsibility to protect their CBA's. They are vastly different and it is not going to be easy. In the end I am sure that I will never see the inside of another 747 cockpit, I have resigned myself to that fact, but I do want to see my bretherin prosper, both Polar and Atlas.
So keep it civil, respect the other guy's opinion, and look out for the slime from Purchase! Maybe all can get through this.
