South Korean electronics company Samsung has suspended a contractor in China after it found "possible evidence of child labour and illegal hiring", at its Dongguan Shinyang Electronics plant.
A new investigation by China Labour Watch found that during busy seasons, the factory hired child labourers and underage students. Their report said:
"These minors will usually only work for a period of three to six months, toiling for 11 hours every day without overtime pay, and the factory does not purchase social insurance for them as required by law."
The report said part-time workers, who made up 40% of the workforce, received no safety training, no overtime pay and no social insurance.
The report came after Samsung said it did an audit and found no child or underage workers at hundreds of Chinese suppliers.
The company said Chinese authorities are investigating and that if they find child labour they will stop using the contractor permanently.
