Electronics contract manufacturer Foxconn Technology Group said on Sunday it is investigating a plant in China that makes devices for Amazon.com, after a US watchdog criticised what it described as harsh working conditions at the factory. A 94-page report by New York-based China Labour Watch, which followed a nine-month investigation, cited excessive hours, low wages, inadequate training and an overreliance on “dispatch” or temporary workers – in violation of Chinese law – at the Hengyang Foxconn plant in southern China’s Hunan province, which makes Echo smart speakers and Kindle e-readers. “We are carrying out a full investigation of the areas raised by that report, and if found to be true, immediate actions will be taken to bring the operations into compliance with our code of conduct,” Foxconn said in a statement emailed to Reuters. Taiwan-based Foxconn, known formally as Hon Hai Precision Industry, is the world’s largest electronics contract manufacturer and employs more than a million people. Foxconn, which also makes Apple's iPhones, came under fire in 2010 for a spate of suicides at its plants in southern China. It pledged to improve working conditions. China Labour Watch said its investigation had found that about 40 per cent of workers at the plant were dispatch workers, far exceeding the 10 per cent limit under Chinese law. Dispatch workers were paid at the same rate for regular and overtime hours, rather than time and a half as required, said China Labour Watch programme officer Elaine Lu. Chinese workers at Amazon Echo factory overworked and underpaid, watchdog says “They were underpaid,” Lu said. “That’s illegal.” Dispatch workers earned 14.5 yuan (US$2.26) per hour, the report said. Workers also put in more than 100 overtime hours per month during peak season, far more than the 36 hours allowed by law, and some worked for 14 consecutive days. Apple in drive against excessive overtime at Chinese factories Amazon said it audited the factory in March and found that overtime and use of dispatch workers were “issues of concern”. “We immediately requested a corrective action plan from Foxconn,” Amazon said in a statement. It said it was monitoring Foxconn’s response and “compliance with our supplier code of conduct. We are committed to ensuring that these issues are resolved.” Foxconn gets Shanghai’s nod in record time to raise US$4.3 billion in initial public offer Foxconn said in an earlier statement that it “works hard to comply with all relevant laws and regulations” where it operates, and conducts regular audits. “If infractions are identified, we work to immediately rectify them,” it said.
