Leaders in business often misunderstand the integral role emotional intelligence plays in successfully leading organizations to success. Studies exist providing data regarding what leaders are like, what leaders do, and how leaders make decisions. However, few studies have explored the relationship between emotional intelligence and effective leadership. Although there are numerous ways effective leadership can be gauged, one sign of effective leadership can be seen in the way a leader chooses a leadership style with which to lead a team. This book integrates these two ideas and examines the the impact of the level of emotional intelligence possessed by a leader on individual leadership style selection in the telecommunications industry. Level of emotional intelligence was measured by the Mayer Salovey Caruso Emotional Intelligence Test (MSCEIT) and leadership style selection was measured by the Managerial Style Questionnaire (MSQ).
