At what price? Certainly not a market price. A contrived price in a private sale is usually going to screw the seller.
I work for a public company. I sell all of my RSUs and diversify when I vest. I wouldn’t use 30% of my cash compensation to buy my company’s stock, why would I hold on to 30% of my compensation in company stop?
If you haven’t checked lately, the public markets don’t exactly have the stomach for money losing companies.
