Six high school students said they “routinely work 11-hour days assembling the iPhone X at a factory in Zhengzhou” despite that type of workday being illegal for student interns under Chinese law, The Financial Times reports. The six claim they’re only a few of the 3,000 students sent from Zhengzhou Urban Rail Transit School to work at the local Foxconn factory in September. They were all told the three-month stint on the assembly line was “work experience” necessary for graduation, depite one student saying, “The work has nothing to do with our studies.” Apple admitted that an audit “confirmed the students worked voluntarily, were compensated and provided benefits, but they should not have been allowed to work overtime.” The students told a different tale, with one saying, “We are being forced by our school to work here.” [via 9to5Mac]
