Emotions are ubiquitous in people's lives. Every day, a large number of emotions change in people, which individuals manage more or less successfully. In organizations, the emotional intelligence of employees, with an emphasis on the emotional intelligence of leaders, is extremely important. Leaders work with a large number of people on a daily basis who are different and have different skills and whose success in the workplace is largely conditioned by their level of emotional intelligence. Emotional intelligence affects both the creativity and innovation of employees as well as the self-confidence of employees. Given that people lead teams, leaders should have as developed a level of emotional intelligence as possible, because through managing their own emotions and the emotions of employees, they manage activities that ultimately lead to the realization of organizational goals. Leaders who have developed emotional intelligence are less likely to make mistakes in hiring new employees, recognize potential in employees faster and direct their employees to adequate jobs, more easily train their employees and guide them in their career development, are more effective in recognizing problems and resolving conflicts and reducing employee stress levels. The paper interviews people who hold leadership positions in various companies and institutions. Interviewees pointed out the importance of emotional intelligence in leadership, the impact that emotional intelligence has on leader performance and on employee performance in general. Given the importance of employee emotional intelligence in the company's business so far, the assumption is that, given world and market developments, emotional intelligence will gain even more importance over time and that leaders will have even more to do with managing their employees' emotions.
