It's being reported that on Monday, Apple put its Taiwanese supplier Pegatron on probation after finding that the company violated Apple's supplier code of conduct by asking student employees to work night shifts or overtime.

Pegatron had mis-classified student workers and falsified paperwork to disguise the violations, and in some cases also breached the code by allowing students to perform work unrelated to their majors, the U.S. technology giant said.

Pegatron is one of a handful of Taiwanese manufacturers on the island, alongside Foxconn  who dominate Apple's iPhone assembly chain.

Apple said in a statement that "Several weeks ago, we discovered Pegatron - one of Apple’s suppliers in China - violated Apple’s Supplier Code of Conduct in its administration of a student work study programme.

Apple has placed Pegatron on probation and Pegatron will not receive any new business from Apple until they complete all of the corrective actions required." Apple did not declare the terms of the probation.

Apple’s investigations had found no evidence of forced or underage labor, it said, adding that Pegatron had now fired the executive with direct oversight of the programme.

Apple's statement added that "The individuals at Pegatron responsible for the violations went to extraordinary lengths to evade our oversight mechanisms."

Apple didn't reveal the length of time that Pegatron would remain on probation and whether or not this action could delay iPhone 12 Shipments for Q4. For more, read the full Reuters report.
