Garment worker Om Srey Soth, 20, sits under a mosquito net in her room in the village of Trapeng Weng, outside Phnom Penh June 29, 2013. Om Srey Soth, a worker at Sabrina (Cambodia) Garment Manufacturing Corp, a factory that produces clothing for U.S. sportswear company Nike, said that she miscarried her baby during recent protests at her factory that turned violent. Most garment workers who arrive from the provinces to work at factories in Cambodia's capital live in tiny apartments packed into crowded buildings. Four or even more people can share a room, costing around $35 per month, usually three by three meters with one light and one electric fan. The garment industry has become by far Cambodia's biggest export earner, with shipments up 10 percent in 2012 to $4.44 billion. As investment in the country's textile industry is surging, so is labour unrest, putting pressure on suppliers to the world's big garment brands to raise wages and improve sometimes grim conditions in one of the last bastions of low-cost factories.
