A similar but more fringe structure that is regaining popularity is the worker collective/cooperative. Mondragon pulls it off to some degree with 10,000+ employees but their structure definitely involves more hierarchy than the smaller coops. 10,000 employees doesn't have to mean 10,000 employees all doing the same work in the same division, you can still have camaraderie within divisions or work groups and organize the entire company democratically. The worker collective gives ownership and influence to every worker and lessens the "us vs. them" dynamic by empowering workers and basically eliminating managers.
