Same is happening in Asiana. The Korean Pilots seem to be developing a negative attitude to foreigners. Not all the F/Os, most are very respectful, but it has been commented on by many foreign Pilots that some of the F/Os are showing disrespect, and getting harder to fly with.
Suspect it is to make their position stronger with the company. In a way, I can't blame them being pi##ed off, as they (Asiana Union pilots) may never see a command, at least not for many years under the present system.
