In the final thesis we focused on the issue of behavior aspects in the financial decision-making process of the company management. The main aim was mapping this topic and determining key behavior factors that lead management to make mistakes. Primary data on this issue were obtained from an empirical survey. The empirical survey was conducted through a questionnaire that containde questions focused on behavior decision-making factors. Using statistical methods we have reached three key behavior factors. By selecting given behavior factors, we have found that love, hate and sadness are key factors that influence management behavior and decision-making. In the real work environment, we chose two managers who were willing to provide us with a review and opinion on the results of the survey. By analyzing all the data, we have come to the conclusion, that even though managers are trying to direct their behaviour and activities, often they do not notice the influence of theese factors, and sometimes they are unable to make decisions. The manager should be able to direct his behavior and activities, be able to self-control and take into consideration the fact, that these factors are always present. We are convinced that the main aim of the final thesis is fulfilled, and we believe, that it will be beneficial to the readers, science, theory and praxis.
