Apple has just posted their annual Supplier Responsibility Progress Report. The report aims to help improve worker protections and factory conditions as well as show audit information for the year. The report outlines how their audit procedure is performed as well as shows results for audits in 2011.

Apple also posted a list of the 156 suppliers that make up over 95% of their supply chain. The main focus of the report is to highlight their continued efforts to improve work conditions and tighten down on underage labor.

Apple-designed training programs have educated more than one million supply chain employees about local laws, their rights as workers, occupational health and safety, and Apple’s Supplier Code of Conduct.

Apple is also offering educational programs for workers to improve their business skills as well as learn more about entrepreneurship.
