The Fair Labor Association said in a progress report that Apple Inc.’s largest supplier, Foxconn, had made all 195 improvements to working conditions that were due by the end of May. Foxconn also completed 89 of the 165 improvements due by next July. The review of working conditions follows a rash of suicides at Foxconn facilities — about a dozen since 2010 — and an explosion at the iPad-making plant in Chengdu in May 2011 that killed four workers...“Some of the most challenging action items —such as compliance with Chinese labor law regarding hours of work — are yet to come, and FLA will continue to engage with Apple and Foxconn to monitor and verify progress,” [the FLA] said.
