TAIPEI (AFP) ― Taiwan’s Foxconn, which assembles products for Apple, Sony and other major tech firms, has admitted some of its student interns worked night shifts and overtime in violation of company policy in its Chinese facility.

“In the case of recent allegations regarding the internship program at our Yantai campus, we have conducted an internal investigation and have determined that there have been a few instances where our policies pertaining to overtime and night shift work were not enforced,” Foxconn said.

The statement ― issued late Thursday ― came after several Chinese media outlets reported that an information engineering university in central Chinese city of Xian allegedly forced students to join the Foxconn internship program in Yantai, Shandong province, in order to graduate.

The Oriental Morning Post quoted some students as saying that they were assigned to assembly lines to make Sony’s PlayStation game consoles instead of doing any work relating to their major and were sometimes forced to work 11 hours a day.

When some students wanted to drop out mid-way, they were told that they would lose their internship credits and would be unable to get their diplomas, the report said.

Foxconn said it had taken immediate action “to bring that campus into full compliance with our code and policies”.
