There are conflicting accounts of problems at a Foxconn factory in China where Apple's popular iPhone is being made.
Foxconn denies that workers staged a strike on Friday to protest working conditions on the iPhone 5's production lines. The company admits there were isolated "disputes," but says they were addressed and work did not stop.
Both a worker's advocacy group and Chinese state media say there was a work stoppage that temporarily paralyzed production lines.
Workers are said to be outraged by what they describe as management's "overly strict demands.'
