Communication is surrounding us. Leaders and followers are not an exception to that rule. Indeed, leadership actors are communicating with their co-workers, their boss, their employees, the media, and so forth. However, in the course of this paper and because of its importance, the focus on non verbal communication will be adopted. Basically, this form of communication is everything except the actual words that people pronounce. Body language, tone of the voice, cultural differences, deceit signals, all these components of non verbal communication and many others will be developed. The core of this work will be understanding the main concepts of non verbal communication and then applying them to leaders’ real life situations.   This thesis will also, among other things, aim to answer the following questions: What is the importance of non verbal communication in everyday life? How are leaders using non verbal communication to give sense? Do they use deceit signals? What influences the non verbal communication? What is the emotional intelligence concept? Can the non verbal communication be extrapolated and be seen as being inter-cultural?
