Summary Box: Curbs promised at Apple factory lines

BETTER CONDITIONS: Chinese workers who often spend more than 60 hours per week assembling iPhones and iPads will have their overtime hours curbed and their pay increased.

THE SPARK: The changes at Foxconn came after a labor auditor hired by Apple Inc. inspected their factories.

THE SIGNIFICANCE: Foxconn's moves are likely to have an impact across the global technology industry. The company employs 1.2 million workers in China to assemble products not just for Apple, but for Microsoft Corp., Hewlett-Packard Co. and other pillars of U.S. technology.
