Exeng. I agree with you, the jailing of guys for withdrawal of labour is barbaric.
However the facts are, as I understand them, that the guys are in jail at the behest of the government, not KAL. The strike was deemed to be illegal, they were notified of this prior to taking action, but still went ahead.
As part of the return to work the FCU negotiated that the company would withdraw any charges they had against the guys. I understand this was done.
If one was to adopt a cynical stance then one could assume that the company and the government were working hand in hand. I do not share that cynicism.
The sad part of the whole affair is that there is no provision for bail in the Korean system, in this sort of matter.
Fortunately the guys are well respected inside the prison as they are martyr's of the working class, and thus are not in the same danger from predators as they would be in the jails of Britain the US Australia etc.
