The world's largest PC manufacturer is working to make sure its Chinese suppliers aren't using student and temporary workers in their factories. Similar to Apple's current supply chain problems, HP has discovered student workers among those employed by the Chinese factories that supply them with their products.

HP isn't having one bit of it. According to HP's new regulations, a student's work "must complement the primary area of study." Also among the regulations is a cap that limits the ratio of student and temporary workers to 20 percent, though they plan to decrease that to 10 percent in the long run.

The labor issues in the supply chain affect all of the major electronics manufacturers. Apple has trouble with Foxconn and Samsung found unacceptable working conditions in its own factories in China. However, it remains to be seen if these companies will follow the example set by HP.
