My former boss is willing to let me buy stocks. Is it worth it?

Not worth it. It is a loss for you to invest in shares like this. You can't get into this store if you buy shares. He also has other hair salons, which should be the income of all hair salons. What's more, it's a small shop and can't stand the wind and rain. How long will it take to earn back after the shareholding? It is difficult to maintain a long-term medium-sized store now. Also, after signing a contract for three years, you should have the right to quit after three years, and it is the corresponding withdrawal money you deserve at that time. There is no discount of 30% to 30%, which is obviously not cost-effective. Since it is a three-year contract, you can deduct 30% from the contract unless you want to quit within three years, otherwise you have no right to deduct your money after the expiration of the three-year contract.
