Worker Cooperatives are democratically run, worker-owned businesses. They are the alternative to the an alienating employment system, involving collaborative self-employment by groups of individuals. Governance of a worker cooperative is based on one member, one vote. People that provide labor are required to become members (after a trial period) so their rights to governance and profit appropriation are protected.
