I have zero interest in stock with the company I work for. To me it's too many eggs in one basket. 100% of my income is dependent on the health of this one company, I don't want part of my portfolio to be as well. If it's given to me for free (I have some with my current job), sure I'll take it, but I'm not willing to trade off a decent salary for it. The other exception to company stock is when you can buy stock at a discount, in which case I would buy it and sell it during the first window possible, as long as it tended to be fairly stable stock.
