Apple revealed its suppliers in response to harsh criticism that it was turning a blind eye to dismal working conditions at partner factories. Apple’s audit found six active and 13 historical cases of underage labor at some component suppliers. It also found a number of other violations, among them breaches in pay, benefits and environmental practices in plants in China, which figured prominently throughout the 500-page report Apple issued. Other violations found in the audit included dumping wastewater onto a neighboring farm, using machines without safeguards, testing workers for pregnancy and falsifying pay records.

“I would like to totally eliminate every case of underage employment,” Apple CEO Tim Cook told Reuters in an interview. “We have done that in all of our final assembly. As we go deeper into the supply chain, we found that age verification system isn’t sophisticated enough. This is something we feel very strongly about and we want to eliminate totally.”
