From the large amount of material coming into my feed daily, it appears more and more grassroots organizations are springing up around the country dedicated to building a robust cooperative sector. United States Federation of Worker Cooperatives is just such an organization.
The USFWC was founded in 2004 when a core of worker co-op members came together with co-op developers, scholars, community organizers, and supporters from the broader co-op sector to strengthen worker co-ops through a national, sector-specific organization. Building on growing momentum, this founding event brought together worker co-op practitioners from the existing Western Worker Co-op Conference and the Eastern Conference for Workplace Democracy, as well as key players in Midwest and Southern states, to galvanize and support rising interest in the worker co-op business model.
This is a great organization if you want to learn more about cooperatives or are interested in starting a coop. They have many resources available including a Co-op movement study guide.
