labor - Trade union takes on GP Batteries on cadmium

A different kind of action from international trade unions suddenly appeared on my radar. The largest Dutch trade union FNV takes on one of the largest battery makers in the world, GP Batteries, who is being accused of poisoning their Chinese employees with cadmium.
New, since mostly the international trade union seldom takes on this kind of cases in China, but fly their automatic pilot in calling for a boycot of China as long as they do not have free trade unions. As noble as useless, I feel.
This seems a good, solid case of international companies ignoring health risk for Chinese workers and - as we know - there is still much to gain here.
The story still lacks much needed details, but that might change in the coming months.
