A strike by workers at shoe maker Yue Yuen Industrial Holdings spread from a factory complex in Southern Guangdong to another in neighboring Jiangxi province on Monday, Reuters reported. More than 2,000 workers from a Yue Yuen factory in Jiangxi went on strike over what they say have been years of inadequate social insurance and housing provident fund contributions by the company. The strike began a week ago after the company missed a deadline to address workers’ concerns. Local government officials urged Yue Yuen to resolve the workers’ demands. The company makes shoes for Adidas (ADS.ETR, ADS.FRA), Nike (NKE.NYSE), Saucony and other global brands.
