Yeah, they're really indoctrinated by chinese propaganda, I can't stand them, and I'm a damn communist.

Workplace democracy can work a vast number of ways, and I can't claim to have figured out what the best way of doing it is, and this is one of the most contentious areas in socialist theory, but I'll give a relatively easy to understand example:

A business running democratically, instead of having a CEO who decides everything, could have weekly meetings where everyone gets together and decides what is needed, pay structure, schedules, etc, building decisions through consensus, and then falling back to a vote if people disagree, they could also work like a modern democratic republic and have the workers elect people to various positions, and then maintain heirarchy, if the business is far too large for consensus building to work.

The way a business works currently, under capitalism, is often with a CEO at the top, who controls a group of people directly below him, and so forth, this results in bad divergent incentives, due to the keys to power problem (if you're not familiar, watch this: https://invidious.asir.dev/watch?v=rStL7niR7gs ). One such example is if i'm a walmart employee, do I give a fuck if walmart does well? No. As long as they don't go out of business, i'll be paid the same, who gives a fuck how well the business does if I'm not a partial owner and have no say?
