Blackmail, threats, passport confiscation, poor rostering
WELCOME TO AIR CHINA.
Air China is only for desperate souls, those of us with good jobs, don't bother. Just let them get real desperate, and start to realize what sort of idiots they are for treating expatriates in this manner.
For those who are in dire need to put food on the table, why bother asking? You don't have a choice anyway, just go ahead and jump and accept the abuse.
