A new National Labor Committee report today accused Microsoft of using sweatshop-style labor at the contractors that produce its mice. A factory owned by KYE in Dongguan, China allegedly uses 1,000 teenage students aged 16 to 17 during the summer as part of a "work study" project that ultimately amounts to child labor. In some cases, students as young as 14 or 15 may even have been used, and the company almost always keeps to hiring girls 25 or younger.
