My opinion.
ALL overhaul maintenance operations will be spun off into a seperate company from Line maintenance. Not just third party work. Yes the TWU will represent the workers as the merger and acquisition language is in place to insure just that initially. The current contract will be honored.
Next contract negotiations, two agreements, one for line, one for overhaul. Overhaul will be required to produce and accept lower pay or AA contracts for AA Maintenance will then be pulled and overhaul will be disolved.
In other words, overhaul is being given one more chance, but this will be the last chance. And this happening, not because the TWU is on the property, but because AA Management would prefer to keep it's own overhaul in-house, but will not continue to do so in a competetive de-regulated industry if it is not long term cost effective.
There, I have placed the rope around my neck, now you decide when to do the hanging.
