Interesting stuff from Business Week. In their article ‘You Are Where You Sit‘, they claim that where you sit influences where you stand:

Those sitting opposite the person leading the meeting tend to be Grumpy or Doc, or a combination of the two, says Livingston. Grumpy is openly argumentative and may be hard to control. Doc is the person who faces off against the leader to show off his or her intelligence.

The person who sits on the leader’s right is Happy–a yes-man.
