FW, please come, get the job then get the rating then leave! its helps us all out, In fact you could make $$$$ living in HKG whilst sending out resumes to another company then pull the pin and go, sending a clear message to MGMT that the conditions and roster and pay are not industry standard.
As far as leaave, goes, bid over a year in advance for it, Not get what you want, Plan to go when it was alocated, and then have it canceled.!
