Agree with the sentiment.
The integration between the two company seniority lists at the merge in 1992 protects the flying. The FWA strengthens that position.
Of course they won't actually do it, the redundancy costs alone, ignoring issues of demand and supply are prohibitive.
All they do, as they did with your 787 crew rest (the agreed to and ratified crew rest) is to sow a few seeds through fleet managers and the flock scatters...
That is the wash,rinse and repeat..
