Google Inc. (NASDAQ:GOOG) topped Fortune's list of the best places to work. This is something that investors should note because a happy workforce is a productive workforce. Google gives workers generous perks like free meals, a swimming spa and on-site doctors along with shuttle-bus service from local train stations and -- get this -- free haircuts and on-site notaries. Of course, Googlers need to work hard to enjoy this largesse.

SC Johnson & Son, Container Store and Whole Foods Market Inc. (NASDAQ:WFMI), Cisco Systems Inc. (NASDAQ:CSCO), QUALCOMM Inc.(NASDAQ:QCOM) and Starbucks Corp. (NASDAQ:SBUX) were among the companies that also made the cut.

Another company I wanted to point out on the list that many people outside the Northeast may not have heard of is Wegmans Food Markets. The level of service that you get by walking into one of the chain's supermarkets is unbelievable. When is the last time a cashier at a grocery store asked you whether you wanted your bags packed heavy or light? There are also great prepared meals. Wegmans prices for run-of-the-mill stuff such as milk or bread are competitive.

This list is a very clever marketing promotion for Fortune magazine. What company wouldn't want to be noticed for treating their workers well? Moreover, what company wouldn't want to crow about it?
