Worker cooperatives:

- A bunch of examples here: https://old.reddit.com/r/cooperatives/comments/p23rxr/what_a...

- Some more: https://en.wikipedia.org/wiki/Common_ownership

- Oxide computer company - idk how exactly the ownership works but AFAIK all workers except sales have the same salary.

- The early idSoftware AFAIK worked similarly with all 4 core gamedevs getting paid the same

Note that nothing says everyone has to get paid the same, it just ends up happening in some examples.

I'd say Oxide is the exact opposite, in that they have the same base salary but they vary compensation by adjustment of equity
