I think it is most unfair to blame Canadian
or any other expat pilots for not doing something about the pay cuts.
Any expat pilot who makes a suggestion to change or modify something will be given a polite lecture on Korean culture and how perfect it is and there ends the matter.
Expats are in Korea to serve a purpose,and whether you are an instructor or a line captain there is nothing you can do to change
the situation.
If you persist then you will end up without a job and in todays market I don't think anyone wants that,so give these guys a break.
