Why don't you ask Lloyd Hill how that worked out for the APA.
The pilots tried the scorched earth, trench warfare approach to publicly viscerally bashing Arpey and management, "negotiating" not only in the press but also directly to the public (no doubt many here saw the billboards on 183 south of DFW), for several years.
Guess what? It got them absolutely nowhere - except in the exact same place as the APFA is: still with an open contract, and with the NMB convinced that the unions are un-serious and out of touch with reality. The new, more rational, leader of the APA said as much himself a few months back:
We told the whole world that we didn't know or care how much our demands cost. We said we didn't care what was going on with the economy or with the corporation's economics. We didn't consult with professional negotiators. We abandoned working within established industry protocols and severed ties with management.
These are some of the reasons the NMB and the United States government put APA in recess. The NMB told us to clean up our act. They told us that it does matter how much our "demands" cost, to quit bickering over internal governance and that we needed a leader who was empowered to make decisions. They were clear that APA's radical rhetoric had isolated us and that APA did not have many friends in Washington.
The reason why private-sector unionism is steadily dying in the United States is because unions have stopped demonstrating their value to workers. Many people no longer see the need to fork over a portion of their pay check each week and don't feel that the "protection" they get in return is worth it - they prefer keeping all of the money and coming and going if they don't like the deal they get from their employer. And before anyone says that the airline industry is different, let us dispense with that misconception by looking at some of the fastest-growing and most successful U.S. carriers today, many of which are primarily or entirely non-union. As I have said before, unions serve a purpose and have a place in our capitalist system, but until they can demonstrate their value both to employees and the consumers who finance them, they will not be sustainable.
Only my opinion - which I know is worth nothing, especially here on this forum - but I think Laura Glading would be very wise to stop trying to make the disagreements between the APFA and AMR into some larger moral crusade about the state of the American worker. When national unemployment remains at a seemingly-structural 9.5%, and when you have literally thousands upon thousands of other flight attendants flying around U.S. skies who make far less than AA flight attendants, that just seems ridiculous, and I suspect will do absolutely nothing to advance the union's cause in the court of public opinion, or with the NMB.
