The preferential hiring was a union to management coordination thing to get union brothers hired. Kind of what unionism is all about I thought. Helping your fellow union brother/sister.
Unfortunately, I have not seen any of that except at the Atlas council. Everywhere else, it seems union councils don't make any effort for other councils memberships when hard times hit. Kind of describes the overall problem in our industry. Too much "I've got mine, pull the ladder up!"
As to the USAPA references. You are probably talking about the videos. I image the same issues NMB, Voting, internal ALPA issues, and RLA are almost exactly the same for the Atlas to Teamsters move as it was for the US Air to USAPA move. Probably they just didn't want to spend time duplicating the same work answering the same questions and snagged USAPA's stuff.
