Apple has found cases of suppliers using child labour and forging audits, the company has admitted. In its 2010 Supplier Responsibility report, the Mac maker looked into the practices of manufacturers and suppliers that work with and for Apple. Human and labour rights, management practices and health and safety procedures were all looked into in the study, which found discrepancies among suppliers. In three cases Apple discovered that 15-year-old workers had been hired and that records existed of 11 other workers who had been hired before reaching legal working ages, although they were all now adults.
