University of San Francisco Ethics Professor David Batstone speaks about his research in writing “Not for Sale: The Return of the Global Slave Trade–and How We Can Fight It” and his launching of the Not for Sale campaign to help end human trafficking.

Manpower was the first company to sign the Principles in January 2006, and in December the company challenged 1,000 companies to join in signing the Principles.
