As mentioned, EQ is often used by big corporations to improve the performance of both senior and middle managers, especially those who manage lots of staff. In addition, it is increasingly utilised by civil servants in government departments and even the military. Emotional intelligence is, therefore, often used as a tool to deal with job performance. In other situations, it is applied to areas like bullying, health and well-being as well as matters relating to self-esteem, such as those associated with drug and alcohol dependence.
