To give an example, ShopRite is a co-op in the sense that all the store owners make purchases together to drive down costs, but from the worker's perspective it's no different than working at any other store. This is an owner co-op, because the owners of each store are working together so that each owner benefits. A worker co-op is like what Twitter is trying to do, where they are holding a shareholder vote next month to determine if the employees can buy out the business from the owners and run it for their own benefit.
