This document discusses engaging the private sector to address human trafficking. It outlines lessons learned from developing guidelines to help companies manage the risks of human trafficking in their operations and supply chains. Some key lessons include understanding the business perspective and incentives, developing a clear business case, and focusing on risk minimization. The document also describes a case study of a large facilities company that lost customers and profits after being associated with trafficking cases through subcontractors. This experience led them to directly employ all workers to better control risks. Multistakeholder partnerships are emphasized as the most effective approach.
