Foxconn denied reports that a plant in China that makes Apple's iPhone 5 was hit by a strike, saying on that its production remains on schedule.

New York-based advocacy group China Labor Watch (CLW) announced that at 1:00PM on October 5 (Beijing time), a strike occurred at Foxconn's Zhengzhou factory that involved three to four thousand production workers. According to the report, the workers were complaining for working during the week-long National Day holidays and also accused Foxconn for putting tremendous pressure on them in order to meet the strict demands on product quality without previously providing worker training.

According to workers, multiple iPhone 5 production lines from various factory buildings were in a state of paralysis for the entire day. It was reported that factory management and Apple, despite design defects, raised strict quality demands on workers, including indentations standards of 0.02mm and demands related to scratches on frames and back covers. With such demands, employees could not even turn out iPhones that met the standard.

iPhone users have been complaining for some minor scratches found on the chamfered edge that surrounds their brand new smartphones, with Apple responding that such minor finishing issues are "normal" and that any aluminum product may scratch or chip with use, exposing its natural silver color.

Foxconn Technology Group denied the report and said the plant suffered only two brief and small disputes several days earlier.

"Any reports that there has been an employee strike are inaccurate," the company said in an emailed statement, adding that "there has been no workplace stoppage in that facility or any other Foxconn facility and production has continued on schedule."

Foxconn Technology Group of Taiwan, the trading name of Hon Hai Precision Industry Co, is the world's largest contract maker of electronics for global brands such as Hewlett Packard Co, Nokia and Dell Inc.
