Cathay will not do anything
Cathay are very busy keeping their very own crew shortage under wraps. They simply don't have time or the inclination to be worrying about the KA problem.
This week alone they have lost 3 more F/O's. Many are now taking the lifestyle choice and passing up the command to remain on a base.
As of 2 months ago, 7 F/O's who were all within 6 months of a command opted for a permanent basing, and all as F/O's. The company has tried to talk them into staying in HK to do their command, but all have "declined" politely.
Part of the problem as I see it, is that many of us joined what we perceived was the best airline in the world to work for. And now, quite simply, it isn't the best any more. The have never treated us fairly. Now, fortunately, there are other options, and the most popular one is to be based in your home country, paid a good income, and work for an airline that treats you as human. Unfortunately that airline is no longer Cathay.
