From the perspective of supply chain labor responsibility, the research team has been most interested in determining whether workers daily lives have improved. The researchers conducted independent surveys in seven factories in the cities of Shenzhen, Dongguan, and Zhongshan in Guangdong Province, southern China. These factories belong to FSP Group, Primax Electronics, Lite-On Group, Tyco Electronics and Volex Group. The research team also asked the concerned brand companies (Hewlett Packard, Dell, Apple, Fujitsu Siemens and Acer) to respond to a questionnaire about social responsibility measures implemented in China between January 2007 and March 2008. The aim was to see how premium brands have ensured workers’ rights in their supplier factories.
