IPhone manufacturer Foxconn (2038.HKG, FW3.FRA) Saturday refuted rumors of a strike at a factory in China, Reuters reported. US interest group China Labor Watch claimed that 3,000 to 4,000 workers stopped work at Foxconn’s Zhengzhou plant on Friday. Instructions to work over the week-long National Day holiday, which ended Monday, as well as excessive quality inspections, spurred the strike, the group said. Foxconn denied any halt in production, claiming that minor disputes on October 1 and 2 were dealt with promptly. The manufacturer also said those working during the holiday did so of their own accord and were compensated in line with Chinese law, which requires a three-fold hourly wage increase. State-run Xinhua News Agency reported that roughly 100 Foxconn quality inspectors stopped work for one hour on Friday after an alleged attack by workers angered over excessive quality demands. The Taiwanese company is one of the biggest manufacturers of Apple (AAPL.NASDAQ, APC.FRA) products.
