Uniformlover.. I think you need to look a little closer at the dynamics of the airline and the purpose of the Crew based in Shangahai. Yes they are being treated unfairly and that needs to change, but they are not employed to replace NZ based Crew. LHR Crew are on a different contract to NZ based Crew but there is no threat of the whole operation being run from there.
I think you need to take your personal gripes out of the equation and post something with facts.
