It's called a union. If workers unite and refuse to suddenly supply their labour it'll cause a lot of changes fast, and sometimes the capitalists just leave and the workers can appropriate the company. Though it is often a good idea to start small and get a little win, and then wait and recruit, and then push for another small change, and repeat. That way the union establishes credibility, solid membership and a reasonably sized war chest for things like getting rid of a CEO, which will take more time and effort than for example protective gear or longer pauses in the work.
