. >> reporter: jill tucker says cambodia does have a special competitive advantage since buyers want associated with ethical labor standards. tucker heads an agency supported by the u.n. and the us government that conducts factory inspections for compliance with the labor standards. >> in the olden days, that is, maybe ten years ago, it was more of a cat and mouse game than it is now. and the really smart producers i think realize that you need to treat your workers well to retain your workers and, and that it's just not worth it to, to not treat your workers well. >> reporter: she cites this factory, run by a taiwan based company called q.m.i., as an example. there's plenty of air and light and relatively good labor relations. all 10,000 of q.m.i.s workers are on permanent contracts and wages range from $90 to as high as $150 a month. it's well above the industry norm but still below what unions say is adequate, given the rising cost of living, especially food. but tucker says demands for more pay, however justified, are a tough sell given realities in the u.s., the biggest market.
