In worker cooperatives, worker-owners can only own one share of the business and no more. This entitles them to a single vote in the business's practice, and all shares are of equal value. Shares cannot be exchanged with any other individual for money or anything else. If a worker-owner leaves a business, their share is returned to the cooperative. A member obtains a share of the worker coop when they enter the business through a process known as a buy-in, the purchasing of a share either immediately or over time (through payment and/or money taken out of their pay check).
