Great question Sandman.
I suspect the answer is something to do with the new DFO/GMA's vision of pilot management. One thing that can be deduced from the new policy is that Management cannot be happy with the existing AMP.
Whether that's because they believe this new policy is actually better, or the resignation rate has got them desperately searching for solutions to make the roster work is a question that will be answered over time!!!
Did I say "overtime"?
