Nike has made an expansive effort to convince consumers, investors and others that it is improving the lives of factory workers who make its products, not exploiting them. A rare view of wages at one Cambodian factory tests this claim.

There is Phan Oem, 53, who says she clocked up to 76 hours a week producing clothing for Nike and other American brands, sometimes forced to work seven days a week. She says she feared being fired if she didn’t work through lunch breaks, on holidays and occasionally overnight. After 12 years spent packaging clothes, her base pay was the minimum wage: $204 a month.
