Following a BBC investigation into alleged mistreatment of employees at an Apple supply chain factory owner Pegatron has announced it will investigate the claims made in the documentary and address any issues it discovers. According to Digitimes, the company filed a statement on December 22 with the Taiwan Stock Exchange promising to implement improvements in their factories.

Pegatron’s statement makes no mention of Apple, which has come out strongly against the BBC’s report. In an internal email, CEO Tim Cook accused the BBC of getting the facts wrong claiming, “nothing could be further from the truth.” The BBC’s report used hidden cameras placed on undercover workers to discover a wide range of issues in the Pegatron factory, including confiscation of worker IDs, overcrowded living conditions, underage workers, and excessively long work shifts.
