trade union - A Japanese employer gets into hot water

Only a few weeks ago I observed that NGO's are booming in China, with perhaps trade unions as an exception - while you see employers' organizations everywhere. And now, there is the first high-profile conflict in the media on a sacked trade union official. Chinabiz summerizes it here, but much of the reporting come from the Asian Labour News.
Much remains unclear, as what the trade union official actually has done to get sacked: might have been something else than trade union activities.
