Apple today issued its latest Supplier Responsibility Report, laying out results of 393 internal audits of its supply chain. While we are encouraged by these results, we will continue regular audits and go deeper into our supply chain to ensure that there are no underage workers at any Apple supplier, reads the report. In all, the company says labor conditions have improved substantially over where things stood one year ago. Excessive work within its supply chain has also lessened. Its now at 92 percent compliance with a maximum 60-hour work week and tracks more than 1 million workers weekly. Apple says many suppliers tell us that we are the only company performing these audits, so when we do find and correct problems, the impact goes far beyond our own suppliers.
