If the union/workers owned a significant amount of shares it could work. Because if outsider investors demand to buy goes up so do their share prices, so it can sort of 'equal' out share dilution . I guess most workers are not paid enough to do so. It would be cool if a company wanted to go public they had to distribute a significant set of the shares between workers. I think Corbyn was trying to do something similar? Also Waitrose (UK supermarket) gives dividends to their workers, and few of my friends really appreciated that whilst they were working part time, but it's still a bit of "big corporate happy family" ugh vibe
