On 8 December, around 1,000 workers at factories owned and operated by the Hong Kong based Gold Peak Battery group organised a two day strike at the Power pack plant in south China in a continuation of the long struggle for proper compensation and protection against cadmium poisoning. Three workers were reportedly locked up by security guards while other workers blocked the factory gates. In the aftermath of the protest, on 22 December, four workers were questioned by police over their role in the strike including Wang Fengping. Wang was released after 10 hours while the other three were kept in detention for almost 2 weeks. Wang Fenping was then fired.
Hundreds of workers involved in the manufacturing of cadmium batteries have been diagnosed with cadmium poisoning or excessive cadmium levels. Gold peak management has not reached a satisfactory agreement over compensation, treatment, prevention and support.
