What about buying shares?

So, here's the stupid idea I just had...

It's just happening now. They pay the drivers less, and the share price goes up.

So, what about some sort of syndicate where drivers buy shares in the company? They would be managed by the syndicate, along with all the other drivers shares, but still belong to the drivers that bought them.

What they syndicate does is manage the shares collectively.

With a big enough stock in the company, the syndicate would have a credible threat against the company.

If the wages go too low and the shares too high, they could to sell all of them, lowering the stock price. Then, pay the drivers, potentially reinvest at lower prices and still maintain some ownership of the company?
