I think CX will have a lot of problems with regards to crewing in 10 years time
It will come sooner than that. KA are already seeing a faster (than before) turnover of ex-pat Standard Contract guys. They come to HK thinking the money's good, but soon find out it isn't, think about having kids - and then the facts hit home. They have little viable option but to leave for a lower paid, but sustainable job elsewhere.
With the new contracts, CX and KA are going to have to face facts that they are now just another 'average' employer. There isn't a huge benefit to hold people here and the turnover will be much higher.
