Emotional intelligence (EI) is the ability of an individual to understand his or her own emotions and the emotions of others. Testing job applicants for their emotional intelligence (in the form of psychological-based tests) is a growing trend in employment today.

If a worker has high emotional intelligence, he or she is more likely to be able to express his or her emotions in a healthy way, and understand the emotions of those he or she works with, thus enhancing work relationships and performance.
