“Employees work excessive overtime, in some cases seven days
a week, and live in crowded dorms. Some say they stand so long
that their legs swell until they can hardly walk. Under-age workers
have helped build Apple’s products, and the company’s suppliers
have improperly disposed of hazardous waste and falsified records,
according to company reports and advocacy groups that, within
China, are often considered reliable, independent monitors.
More troubling, the groups say, is some suppliers’ disregard for
workers’ health. Two years ago, 137 workers at an Apple supplier in
eastern China were injured after they were ordered to use a
poisonous chemical to clean iPhone screens. Within seven months
last year, two explosions at iPad factories, including in Chengdu,
killed four people and injured 77. Before those blasts, Apple had
been alerted to hazardous conditions inside the Chengdu plant,
according to a Chinese group that published that warning.”
