There's no need to divest entirely, assuming a reasonable portion (say, no more than 3-5%) of total holdings is in company stock. That said, I have heard someone in my company say they refuse to invest in tech stocks at all, because they're concerned about a sector-wide downturn taking out both their job and their investment gains. I think that's a bit of an extreme position, but I understand where it's coming from.
