You can strike but you won't because:-
1. Most people are thousands of miles from home and feel very vulnerable to becoming numbers 50-150 on the 'you've just lost your career' list.
2. The AOA is toothless and will not/cannot back you up.
3. CX have done a brilliant job of painting us as greedy, lazy, overpaid button pushers ( until something goes wrong where they reluctantly say something nice).
4. Labour laws in Hong Kong favour the 'Mill Owners'.
5. Hundreds of people are waiting in the wings to take your job ( see No 3).
Just do your own CC - don't even think about the 'S' word - it's not going to happen.
