The working conditions at Chinese factory Foxconn have been scrutinised previously, and this time it seems the factory has been making use of school children ages 14 to 16. It is reported that they worked both overtime and nights.
While they were never forced to work by Foxconn, they were told by teachers that they would not get credit and risked relegation if they refused to work.
"I did transport work, helping them move goods," a 14-year old buy told Chinese National Radio (via Kotaku "Right now, the night shift is 7:40 PM until the morning... you know, til what time in the morning is uncertain. Whenever the work is done is when you get off your shift. If you don't finish the work, he (the production line foreman) won't let you end your shift. Usually, you can get off by 7 AM. My arms would hurt from the work."
It should be noted that while the conduct isn't in violation of Chinese labour laws, Foxconn are looking into the issue as it violates their policies. Nintendo are also investigating the issue.
