Not visa versa. 109 is OPEIU. OPEIU is the union with locals. Each local is a separate entity under the OPEIU. Why would Local 109 try to incorporate a whole separate class and craft under its AMC Pilot's local? Why wouldn't those other groups not want their OWN local governmental structure, with their OWN executive board and financials? Why would they want to jumble up their existence in a Railway Labor Act system? They wouldn't unless someone in the 109 was trying to organize them themselves.
It would be dumb for 5hem to organize under under another local. Just ask CareFlite pilots, who are used to fund the PHI bubbas who don't even know CareFlite exists (other than the dues money they get from them)
