Work Rules! is the title of a great book by Laszlo Bock, SVP of People Operations at Google.
It's a pretty accurate portrait of life at Google (at least from what I've seen over the last three years), and at the same time it is a great guidebook for companies that haven't yet come as far along the path of employee empowerment.
If you are in any way involved with work - be it employer or employee - this is a must read, with lots of practical advice on how to improve your organization (and your life!). It may also give you a bit of an idea of why I consider Google such a great place to work, probably the best I've seen so far anywhere.
