I’ve worked for bullies in the past and I also know that law firms are filled with them. Becoming a parent and observing the behavior of infants, toddlers pre-schoolers has given me some good insights into the psyche of a bully (my own personal view is that bullies are stuck in some earlier developmental stage in their lives–ever see a grown man have a tantrum?)

Learning how to communicate strength through your body language and use of eye contact can help you project more power (watch your dog tuck his head down in submission if you stare at him from above.) Here is what an expert on workplace conflict has to say on the subject.
