What is it that makes some people better managers than others? Why are some employees highly motivated and more productive than others? The answer is largely to do with Emotional Intelligence (EI). Research shows that managers high in EI exceed targets by 15-20%. Those low in EI under-perform targets by 20%. 58% of performance on the job is driven by emotional factors like self-awareness, personal discipline, picking up on social cues and building effective, working relationships.
