Apple Computer said Thursday that it had found no evidence of forced-labor conditions at a Chinese factory that makes iPod digital music players. But it said that a company investigation found several violations of Apple’s code of conduct and that the supplier, Foxconn, was changing its practices as a result... Apple said a team from its human relations, legal and operations staffs interviewed 100 randomly selected workers and reviewed thousands of documents including personnel files, payroll data, time cards and security logs... “We did find that the weekly limit on hours worked was exceeded 35 percent of the time, and so the supplier is changing its policy as a result of the audit,” an Apple spokesman, Steve Dowling, said... Foxconn is the trade name for Hon Hai Precision Industry,...whose customers include Intel, Dell and Sony... Apple...also said that it had found two instances of employees being disciplined by being forced to stand at attention, and that it had initiated a manager and employee training program to reinforce a “zero tolerance” policy toward harsh treatment. Apple said it had engaged Verité, a nonprofit auditing and research organization that monitors work conditions, to track the situation.
