Fresh off a billion-dollar loss in a patent fight with rival smartphone maker Apple, embattled Samsung Electronics Co. now finds itself accused by a labor rights group of mistreating workers in China and illegally using child labor. The New York based-China Labor Watch said its investigation into workplace conditions at eight factories in China showed some employees were working more than 100 hours per month of overtime and that children were knowingly employed.

The factories are owned by Samsung suppliers. Samsung says it is undertaking a review of labor policies with its suppliers.
