Typical Korean cutthroat, ruthless business style. Not surprising at all. That's why Korea has the highest corruption rate in the corporate ranks among the first world countries; actually, the way they act, I'm surprised Korea is even considered as a first world. Almost as bad as the Chinese. [FACT]
It's fruitless to whine and complain about Korean Air. They DO NOT CARE for the expats, let alone their own employees. They're just corrupted pigs, along with other Korean conglomerates. Korean Air (Hanjin) was already pretty much broke financially, like Asiana Kumho Group, way before this Chinese Virus started due to money-laundering and bad, mismanaged, selfish, Korean-style business practices. [FACT]
I won't get into the legal aspects concerning how you were screwed over by Korean Air and your Contract Puppet Company on Pprune because I am not a lawyer. But good luck to you and everyone else in the aviation industry.
