I'm fairly sure that the rest of the world will slowly be dragged along behind the UK & EU so when the age discrimination act comes along in HK, those extending past 55 will have to be given their current package.
Hence PW's irritation in his latest missive that he doesn't think an agreement will be forthcoming. They've generously improved the package, but until it matches that which will be enforced shortly anyway, why would anyone vote for lesser terms?
Not to mention the ridiculous idea that these more experienced pilots should be paid less anyway.
