Recent years have seen management look for ways to increase work performance, on an individual, group and organisational level. In doing so, the need to determine good contributors to work performance has come about. Emotional Intelligence has played a key role as one of the main contributors to increased work performance and is a fairly new area within Personality and Intelligence Psychology. This book aims to review the current literature on the relationship between Emotional Intelligence and individual work performance. Some significant links have been found and the idea of Emotional Intelligence as a moderator to performance is introduced. This book should help compartmentalise the current ideas about what Emotional Intelligence is, what individual work performance is and how the two have been researched in order to highlight Emotional Intelligence as an area in Workplace Psychology that should be harnessed and practically used to develop performance in organisations. This book puts forward suggestions for future research within the field as well as highlights some practical and theoretical implications for managers and psychologists.
