I can't remember getting a choice.I asked to change to APP/RAD after 2 years in the TWR at CLK and was told it was a big cannot.I was one of the youngest Gweilos with 18 years experience on APP/RAD at the time.So I just came home,and went back to TWR and APP/RAD here.
Since the time I went to HK until now,here there has been 9 pay rises with another due next month.HK has more or less stood still.I think a lot of Gweilos are just holding tight until retirement.
