FYI,
A good friend of mine brought the Teamsters on the property at North American. He became their N/C Chairman for two years. He is now at CAL and although he wants to strangle John Prater, he would take ALPA any day of the week over the Teamsters.
One thing about ALPA, it is independence plus. Your MEC sets its own objectives and agenda. So it really comes down to the guys you elect as your LEC reps who also are the voting body of the MEC. Those MEC reps elect the MEC Officers (MEC Chair, Vice Chair and SEC/TRES) to carry out the day to day operation of your MEC.
Good luck.
PS Not sure which local of the Teamsters your airline is considering. But the one run in Houston in an old gas station by Gene Sewell is not worth much. Gene was a former attorney for the IACP (the former CAL Independent Union) and wasn't a favoriate at our union. My friend from North American was in this Teamsters division and was very unimpressed with their services.
