Gordon Bethune the former(?)CEO of Continental Airlines wrote a book about his strategy for turning around the twice bankrupt airline. (From Worst to First) In one chapter he talks about aircraft mechanics.
He said mentioned how if a mechanic is pissed off he simply will not fix the airplane, sure he will work on it all night and day but you wont get it for when you want it. He also said that when mechanics are doing this that there isnt much you can do about it. There is no way of telling what is going on inside the mechanics head. Is he really trying to fix this or just going through the motions, does he know whatsw causing the problem or not? however when they are motivated they often take on fixing it in time for a flight as a heroic(if only in their own minds) challenge and take great satisfaction in getting it out on time.
One of the reasons why AA is not earning as much as they could is because of all the aircraft that go out of service everyday and the extra aircraft they have sitting around to cover for cancellations. As AA and the TWU continue to play mind games on the line mechanics, thinking that they will come to accept their reduced standard of living and go back to the days when we all took on our daily heroic challenges, which is not going to happen, the company continues to lose money. Its sad because we are only talking about 4000 or less mechanics where if their pay hadnt been so drastically cut not only could the company continue to reduce headcount through attrition but they would likely see a dramatic reduction in delays and cancellations. The company could have enjoyed better productivity than SWA when you factor in that AA has multiple fleet types and ETOPS.
