We see conflicting reports today out of China. Rights group China Labor Watch says that “multiple iPhone 5 production lines from various factory buildings were in a state of paralysis for the entire day” yesterday after as many as 4,000 production workers at Foxconn’s Zhengzhou factory went on strike. Employees objected to the company’s requirement that  they work on the country’s National Day holiday that runs from October 1 to October 8, and its failure to train them to produce phones that meet its standards, the group reports. Workers also said that design defects make it difficult to fulfill requirements that phones have no scratches on frames and back covers, and no indentation of more than 0.02 mm. That led to fights between production workers and quality control inspectors., “This strike is a result of the fact that these workers just have too much pressure,” says CLW Executive Director Li Qiang.

But Foxconn calls the reports of a strike “inaccurate,” according to a statement it provided to Reuters. It added that “there has been no workplace stoppage in that facility or any other Foxconn facility and production has continued on schedule.” It acknowledged that there were disputes last week, but says they were “immediately addressed and measures taken, including providing additional staff for the lines in question.”  It also told the news wire that only volunteers worked during the National Day holiday, and they were paid three times their usual compensation — a standard set by law.
