A report by a campaign group which criticised the working conditions at a factory where iPhones are made has received a response from Apple according to the BBC.
Only 10% of the workforce can be temporary under Chinese law.
Foxconn workers were not getting bonuses, working overtime and too many temporary workers were being hired.
It claimed that 50% of the staff in the factory were temporary including students who were not receiving promised bonuses.
Apple admitted the number of temporary staff “exceeded its standards” but denied the other claims.
“We have confirmed all workers are being compensated appropriately including any overtime wages and bonuses, all overtime work was voluntary and there was no evidence of forced labour,” Apple said in a statement.
