Foxconn admits that 56 underage workers as young as 14 work at its Yantai plant in China, where the Wii U is being tested. Foxconn fires the underage workers and promises to take measures so this does not happen again. Nintendo says:
Nintendo is in communication with Foxconn and is investigating the matter. We take our responsibilities as a global company very seriously and are committed to an ethical policy on sourcing, manufacture and labor.
