Late Thursday, Apple updated its public Supplier Responsibility Report [PDF] with news that it had increased audits throughout the company's supply chain by 72 percent over 2011 levels. It also reported an increase in compliance among suppliers with a 60-hour work week maximum, now at 92 percent. The biggest news, however, is that Apple fired one of its suppliers -- Guangdong Real Faith Pingzhou Electronics (PZ) -- after uncovering some 74 child labor violations, along with reporting other suppliers for not paying sufficient overtime.
