Mondragon Corporation

Mondragon began in 1956 in the Basque town of the same name, when a Catholic priest, José María Arizmendiarrieta, and a small group of his technical-college students founded Ulgor, a maker of paraffin heaters that was converted into a cooperative in 1958. It became the seed of what's now the world's largest worker-cooperative federation.

Each of Mondragon's 81 member cooperatives is owned and governed by the people who work there, on a one-member-one-vote basis through a General Assembly — regardless of role or seniority. That's a meaningfully different structure from a trust-based model like John Lewis's: there's no trust standing between the worker and the business, because the worker directly is the shareholder. Many cooperatives cap the ratio between the highest- and lowest-paid worker, typically between 3:1 and 9:1, averaging around 5:1.

Mondragon's wider corporate group is larger than its 81 member cooperatives — it also includes conventional, non-cooperative subsidiaries, particularly some international manufacturing operations, whose employees aren't co-op members. The federation's own reporting counts roughly 71,000 people employed across the group as a whole.

What makes Mondragon distinct from a single worker-owned company is the federation itself: a shared cooperative bank, university, and inter-cooperative solidarity fund that lets member businesses support each other — including moving workers between cooperatives rather than laying them off during downturns.
