Yes Akali very good point. Ground school and type-rating etc are company business and should never be at the pilot's expense. As bad as Korean may be however I don't believe they have stooped this low yet (?)
But the no-shows and general dissatisfaction with life in Korean tell a bigger story. Like any airline, KAL will need to significantly and rapidly improve the way expatriate pilots are treated or they will not fill cockpit seats and the business will suffer dramatically.
Of course this works both ways - expats need to be culturally sensitive and discrete (sometimes lacking in my observation) but at the moment the onus is on KAL to make life better for their foreign crews. Many of us have choices as to where we offer our professional pilot skills and at present KAL doesn't ad up.
