Abstract
For a very long time, in common sense, the only intelligence was measured by the intelligence quotient. Indeed, in each company, intellectual intelligence took precedence over the other kinds of intelligence. People who showed their emotions were seen as weak persons. This period is completed. A concept is emerging for a few years, the one of emotional intelligence as factor of leader's success. Indeed, many researchers worked about emotional intelligence and its role on individual's behaviour. Effective, flexible, ethical? What competences must have a leader? What is emotional intelligence? What is the link with leadership? So many questions will be explained in this report. After an explanation about what emotional intelligence is and the importance of leadership in the workplace, the link between these two concepts will be studied. The last part of the report will focus on emotional intelligence and trainings.
