Abolish the overtime exemption for computer systems analysts, computer programmers, and software engineers. Make it unprofitable to extract labor until someone dies. All other actions are impotent.
Most western countries are democracies because people got fed up of being exploited by dictators (sometimes called "kings"), removed them and setup a system in which they elect who makes the decisions. This system has issues but is less bad than dictatorship.
Yet, companies kept their hierarchical power structures.
Workers should decide who makes the decisions. If they don't wanna invest time into selling their product, they hire a salesman. If they want somebody to make long term projections, plan what gets worked on and communicates with other teams, they hire an assistant. And they decide how much he gets paid according to how much value he actually brings them.
Managers should be assistants.
The more interesting question is: Can communalism work without the community having a deep attachment to the idea? The Hutterites achieve that through religion, but if you threw a group of random people together into a similar economic situation without some kind of strong belief system would they endure or would it quickly devolve back to what we see in the broader economy?
