Taiwanese factories in Dongguan [a city between Hong Kong and Guangzhou and a major centre of manufacturing] are facing a problem. According to a news report in the United Daily in Taiwan, over a thousand workers at a factory, which produces goods for big brand names such as Nike, demonstrated for two days and damaged equipment and factory cars. 500 armed police arrived and quashed the riot. Several leaders were arrested. The main cause for the riot was the limitation [sic] on working hours at the factory. The shorter hours have been requested by US companies so as to avoid criticism from various groups on long working hours. However, the mainly migrant workforce want to work longer hours so they can earn more. Consensus had been reached by the US companies, the Taiwanese-invested factory and local government that the maximum working hours per week should be set at 60 hours [which is still a breach of Chinese Labour Law, but less than other manufacturing plants]. However, this reduction in hours was unsatisfactory for the workers and the resulting riot was serious [emphasis added].
Whole thing here. [Hat tip: MR]
