Emotional intelligence (EI) refers to having the ability to recognize and understand emotions and their impact on behavior and attitudes. Those who have a high degree of EI are in tune with both their own emotions and the emotions of other people with whom they come in contact. EI involves being sensitive to and perceptive of other people’s emotions, and have the ability to intuitively facilitate improved performance based on this knowledge. The modern workplace is characterized by open communication, teamwork, and a mutual respect among employees and their supervisors. EI has effects on the sales since the customer has created a trust. Consumers don’t want to do business with someone whom they don’t trust. Managers with emotional intelligence understand that their staff members are people first. EI is needed because it includes self-awareness, self-regulation, motivation, empathy, and people skills. By these skills the employees can understand their own strengths and weaknesses which allows for motivating others. Having EI gives success because it gives a better understanding of needs of the customer.
