It's also meh. The money gets tied up in the company until the shares vest (my wife had to wait like 8 years or something). It's performance is tied to the performance of the company and you can't diversify. Lots of times it doesn't end up giving you all that much extra. I'd much rather just get a bonus I could invest elsewhere.

ESOPs were invented as a way for owners to cash out. Not really an altruistic thing that works well imho.
