Emotional intelligence is the term in the nineties of psychology that John Mayer and Peter Salovey introduced in terms of the ability to process emotional information as a construct relatively independent of traditional cognitive abilities and personality traits, but with no greater echo in academic psychologists. However, when Goleman (1995) published the book "Emotional Intelligence: Why It Can Matter More Than IQ?" And he introduced the concept to the general public, the practical interest he had been was quick and intense and supremely overwhelmed by scientific interests. According to Goleman, emotional intelligence creates non-cognitive abilities, competencies, and skills that affect the ability of a person to cope with the demands and pressures of the environment. Emotional intelligence is partially acquired by genetic inheritance, but a significant part of the learning process. Two methods, a questionnaire, and an interview were used in the empirical research. An anonymous questionnaire resolved 42 people in management positions via the Google Forms platform. The questionnaire was solved by 42 people, was anonymous, and Google Forms was used as a simple tool for solving and analyzing data. The results indicate an insufficient perception of the importance of emotional intelligence in Croatian managers, as well as the inadequate quality of knowledge of what emotional intelligence actually is. As the questionnaire was anonymous, it can not be accurately determined whether there is a difference in the perception of emotional intelligence importance in small and medium-sized, and large enterprises. The answer to this issue could be a part of potential future research. The interview was answered by 8 managers, and the results show a high level of emotional intelligence of the respondents, but as in the questionnaire, insufficient level of knowledge of what emotional intelligence actually is.
