Stated differently, maybe the ALPA guys aren't going to jump through hoops trying to satisfy your (PD's) quest for info, when your quest has consisted of replacing the union. Maybe the guys that work hard for free, and have been getting lambasted by the DPA for years, are tired of addressing non-stop complaints, real or imagined.
Maybe this is the flip-side of having invested years of trying to replace a machine with another machine, instead of helping, and reforming? My biggest gripe with the DPA is that they never seemed to want to make a positive impact, to the detriment of everyone.
I met TC years ago, when he gave me the sales-pitch on a layover. He had a number of complaints. I kept asking him why he wasn't sending his followers in, to take over the MEC, or effect his changes. He said that wasn't what his movement was about. He said he could take over the MEC the next day, but what had to happened is that the DPA had to remove ALPA.
You tell the guys trying to work for ALPA, and trying to reform ALPA, that you're not there to improve, just kill ALPA. You keep doing that for years, and ultimately fail to kill it... don't be surprised if your input doesn't get immediate results every time.
I'm not speaking for the volunteers, or ALPA: I'm just speculating as to how I would address it their shoes. I think I would spend the precious time I volunteer trying to help those who want to be part of the solution. I'm not suggesting those volunteers should be arrogant, or fail to consider the weak areas of the union. I just think that they would probably feel most interested in solving the real problems of the majority, and they probably would feel they've been sufficiently insulted by the wannabes.
