Have you looked into worker cooperatives? Ocean Spray is an example in the US. Mondragon is an example of one in Spain that has tens of thousands of workers and has existed for many decades.
I wouldn't characterize any agricultural co-op like Ocean Spray as the same category as a worker co-op like Mondragon. There is a very distinct line between a farmer, who's an owner, and a farm worker, who handles most of the day-to-day operations.
I wasn't talking about farmer cooperatives. Worker cooperatives are owned and run by the workers, thus the name. Certainly some cooperatives are not worker cooperatives.
