Mainframe are you serious? Sure we make our own calls in life, and the crew did just that. They decided that being cabin crew for a national carrier was not for them.. Qantas advertises all around the world for people to visit Oz and fly on their crap airline. It is not good enough for crew to then decide not to fly with them. Be security aware indeed, voice your concerns, have the checks done then get on with it. I they can't handle that then open a coffee shop in Paddo.
