A number of unions are exploring ways to ally with cooperatives and to form new ones as alternative strategies to save their members’ jobs and create new ones. About 10 years ago, unions started to think again about the cooperative model. The Union Cooperative Council formed in 2007 and is part of the U.S. Federation of Worker Cooperatives.

The idea was to start manufacturing cooperatives. In 2012, USW, Mondragon, and the Ohio Employee Ownership Center published their Union Co-op Model, outlining how union cooperatives could be structured.
