Sean Sellers has been involved with efforts to improve labor conditions in U.S. agriculture since 2003. As a board member of Just Harvest USA, he works closely with the Coalition of Immokalee Workers (CIW), a community-based farmworker organization headquartered in Immokalee, Florida. From 2004-2007, Sellers lived in Immokalee and served as a national co-coordinator of the Student/Farmworker Alliance. The CIW's Campaign for Fair Food uses creative methods to educate consumers about human rights abuses in the agriculture industry, the need for corporate social responsibility, and how consumers can help workers realize their social change goals. The campaign has won support for farm labor reforms from retail food industry leaders -- including Yum Brands, McDonald's, Whole Foods Market, Compass Group, and others -- with the goal of enlisting the market power of those companies to demand more humane labor standards from their Florida tomato suppliers. The CIW has also aided the Department of Justice in the prosecution of six farm slavery operations involving well over 1,000 workers.
