Students from the Xian Institute of Technology responsible for assembling the PlayStation 4 were forced by Foxconn to work overtime to finish building the next-generation console.
The company allegedly informed students that they would not receive the credits allowing them to graduate if they did not finish up the internship program.
Responding to the report, Foxconn confirmed that it dug up violation of its policy following an internal investigation, with students being assigned night shifts and overtime at its Yantai factory.
"Immediate actions have been taken to bring that campus into full compliance with our code and policies," said Foxconn, which includes "reinforcing the policies of no overtime and no night shifts for student interns, even though such work is voluntary, and reminding all interns of their rights to terminate their participation in the program at any time."
Students were “free to leave at any time,’ notes Foxconn, though those that did opt to leave did not receive any credits.
PS4 is due out in the U.S. on November 15 and in the U.K. and Europe on November 29.
