The pay is certainly a joke in KAL now. Their only leverage is the commuting arrangement which makes the Chinese 6 on 2 off sounds unbearable, for those with family. Although many are now more attracted by pay (and tax agreement for my case in having a almost 40% pay increase) to head westward.
Rumour from the mills was that don't expect any pay increase. Too many are still applying from everywhere, the Koreans will not be short of applicants, and that apparently, is their only tool to justify salary adjustment.
