If televised visits by Apple's top-brass to Foxconn's manufacturing facilities, and commitments to improve working conditions were mere PR exercises meant to cover up the issue of dismal working conditions, they failed. About 1,000 workers at Foxconn's manufacturing facility at Chengdu rioted on a large scale, which took the police several hours to subdue. According to media reports, the riot started when the facility guards were trying to stop a thief, while other workers who held grudges against the guards prevented them from catching the thief. Soon, the situation went out of control, as 1,000 workers started a riot. The workers were seen chucking pots, pans, garbage, and even fireworks from their dormitory windows. Public facilities sustained damage, the police made several arrests. The episode reveals that worker-management relations, at least at the Chengdu plant, which manufactures a massive amount of iPhone and iPad products for Apple, are at a breaking point.
