airplaneridesrfun,
It seems you want to use a machete where a scalpel is more appropriate. I believe the goal should be to create as little as possible pain.
Sorry, if your personal agenda is being altered by this (so is mine) but as I said before, there are more important issues here. Seniority is not the only parameter here. In life sometimes you give and sometimes you get. Maybe it is now the time to give. Over the longer term, everybody will be happier.
Agree with GTC58, there is nothing illegal about commuting to the US for work, as CX is a non US company. It certainly did not appear illegal, when the guys took a base.
FedEx has a base in HKG, UPS a base in Germany and all these positions are filled with US guys. I don't see any Germans protesting and claiming entitlement to these jobs.
