This paper by Rebecca Lurie and Bernadette King Fitzsimons highlights strategies used by labor unions to support the creation of worker cooperatives and other worker-owned businesses. It gives a brief overview of the potential for unionization and worker ownership to strengthen workers’rights,and a list of seven union resources to use toward the creation of worker-owned businesses. The paper includes seven case studies of interaction and collaboration between labor unions and worker-owned entities, in which unions get out their tools to apply their power and capacity toward worker ownership for expanding avenues for worker power.
