Non-verbal communication is a vital part to human interaction, particularly in the workplace where influence, perception and impact are experienced across industries, from networking to the interview process to everyday dealings at work. Marc Salem is considered one of the foremost authorities on non-verbal communication and has spent over 30 years studying the mind as a researcher, professor and mentalist on stage - another non-traditional position that's been successful. Marc gives Tim Muma an inside look into the little things we do that give us away and how we can interpret words and behaviors. He also gives us advice on how to influence others in a variety of workplace situations.
