you're hated by your fellow pilots too
Good you said that. Would you not feel the same at home in your own (national) turf if Koreans came and got jobs supposed to be for the nationals of your own country? It's a natural reaction. One just needs to be on the right. Be professional, do the job, get the money and out when you have done your targets.
Happy New Year to all in aviation on the ground and up in the air!
