Apple is investigating a supplier factory in China for alleged labor violations after a watchdog group claimed the facility forced its employees to work long hours assembling iPhones, reports “Computerworld’ (http://tinyurl.com/kjhk8qa)

On Thursday, China Labor Watch posted a report that claimed workers at the factory in the city of Wuxi were logging more than 100 hours per month in overtime to build plastic cases for a budget iPhone device. Apple says it’s already sent a team of experts to look into the matter.

“Computerworld” says the conditions at the factory appear to contradict Apple’s assertion that its suppliers are capping the work week at 60 hours. However, Apple says Jabil has an “excellent track record” of meeting the company’s high standards on work conditions.
