A factory in Shaanxi province has been found using unpaid teenaged workers, the South China Morning Post reported. Four workers aged 14 to 16 were found in a quilt factory in Qishan county. They had been working 12 hours daily since February, receiving only food and shelter. The factory has been sealed off and its owner has been ordered to report to the Labor Bureau today, where he is expected to be fined US$660 per worker. The workers were discovered by a reporter from the Sanqin Daily. Last month, authorities found 379 people, some apparently abducted, forced to work in inhumane conditions in brick kilns in neighboring Shanxi and Henan provinces. The discovery caused public outrage and led to the central government pledging to crack down on underaged and forced labor.
