An investigation by the Fair Labor Association into factories operated by Apple supplier Foxconn in China found poor working conditions and worker abuse, leading Foxconn to pledge it will make improvements.

A month-long investigation by FLA revealed compensation issues, health and safety risks, and issues that have led to a "sense of unsafe working conditions among workers," the organization said in a statement.

FLA claimed it gave Foxconn "a full-body scan through 3,000 staff hours," and surveyed more than 35,000 workers, while investigating three of its factories. Foxconn is Apple's largest supplier and makes the iPad and iPhone. Independent groups have urged Apple to address the poor conditions of factory workers in China.
