Apple has cut off major supplier Pegatron from new contracts following the disclosure of student labor violations at some of the Taiwanese manufacturer’s China-based facilities. Apple found Pegatron to be falsifying paperwork in order to cover up violations of Apple’s code of conduct for suppliers.

Pegatron is one of Apple’s biggest supply chain partners. The company is now reportedly on probation, but wo n’t win any new business until the matter has been resolved.

Pegatron misclassified the student workers in their program and falsified paperwork to disguise violations of our code.’we have a rigorous review and approval process for any student worker program, which ensures the intern’s work is related to their major and prohibits overtime or night shifts,’ Apple said.

Apple is yet to be convinced that the student workers will return to their homes or schools with proper compensation. Pegatron’s own statement says Apple is still not convinced that Apple will not be convinced.
