sanscript: On the top of my head I can at least give you these examples (and there are more of them).
One is a tech company not far from where I live. I don't remember how exactly how they did it now, but basically they get paid like a normal worker, they all pitch in on decisions the company should take, and they get split bonuses from rest-income/shares they own. I don't remember how big they are but they're less 50 at least.
A family member of mine makes games and also get a share of the bonuses the company creates.
CDPR has something similar, workers there are promised at least 10% of the revenue from CP2077 sales (still too low but it's something).
I think it's more common in small sized tech companies. The bigger they get the more greedy the owners also get :)
Well, yeah, paying extra bonuses to workers when the company is doing fine is quite normal. My boss called me last week and told me that I (and apparently others) will get an extra 700€ bonus to my Dec salary as an annual bonus. Last year it was 400€ so I guess we were doing better this year than last year. I don't even recall how that bonus is calculated, somehow related to how much profit the company is making, and it is not relative to your salary like such bonuses normally are in other companies where I've been.
Earlier i worked in a big megacorp (they were in the business of clubbing seal pups and eating babies), and I tended to get bigger bonuses there, e.g. one good year I recall getting several thousand's worth of bonuses. But then some years I didn't get any when the company made loss. A long time ago I also obtained some options and shares from the company as part of my salary, but in the end they weren't worth much when I finally sold them (they started giving them to some workers (group managers etc. that I was at that point) after the biggest growth was past already, only high executives got them before that of course).
Oh and in a bank where I worked in, they offered an option that you can buy the company (bank) shares with part of your salary every month, and there was some incentive to do that too like that you had to pay only half of their price or something like that (ie. it was a much better deal than buying their shares yourself, and you would most probably make some nice profit with the shares due to the lower price).
So in that sense there are normally options to buy company shares and there are bonus options, but buying shares is optional. It is still not the same that every employer automatically becomes the owner of the company that will get part of the profit of the company till the day they die. Sure if they have company shares, they will get dividends if the company decides to pay them for shareholders, but that is normally peanuts compared to monthly salary.
