Companies We Keep is an interesting look at converting an existing business to a worker-owned cooperative. It is NOT a how-to manual on this process; if you are interested in pursuing such a conversion (or starting a cooperative from scratch) you'll need to look elsewhere for more technical support. But Abrams gives numerous anecdotes about the process and the principles behind it, and is open and honest about his own intellectual journey towards the conversion and the challenges and benefits that emerged. The conversion did not create a utopia, but it did broaden possibilities and create new opportunities, and hopefully this story can inspire others to embrace the same path.
