Just a bit of background on the FAAA - back in the days of female only domestic cabin crew there was the Airline Hostess' Association, formed in the 1950's. It covered Ansett, TAA, East West etc. After males were allowed to become cabin crew it became the Australian Flight Attendant's Association. The Qantas Flight Stewards and the Australian International Cabin Crew Association amalgamated with domestic AFAA in 1992 to become the FAAA. My memory is a bit hazy but I think the merger of the two was due to government laws stipulating a minimum size of unions to be legal.
Divide and conquer is what Qantas wants, there is more power if all cabin crew stick together as a united front.
