Labor activist Huang Qingnan, who was promoting the law, was stabbed in broad daylight...So who was behind the attack? "The factory owners," Huang says...Jin Chunyi...worked with toxic chemicals in a printing ink factory. Recently, she learned she has a low white blood-cell count. Her boss has already spent more than $130,000 on a fellow worker who got leukemia...Several weeks after the contract law went into effect, the factory offered Jin two months' severance and told her to leave.
