There is no 'hiring ban', the AOA has been silent on this issue, no one has been laid off to create the vacancies at AHK, the aircraft could as easily been shunted off to another CX subsidiary, etc etc Consequently those pilots who wish to accept whatever the terms are at AHK are doing nothing wrong. If there is an issue between the AOA and CX over the set up as being organised then get on and fight the company. But, as usual, you won't and will instead like a pack of childish bullies attempt to intimidate the new joiners at AHK.
