The idea of organizing work through a four-day work week is increasingly becoming popular, both on the global and regional markets. One of the main arguments why the shortened working week is gaining attention, is because of the potential of balancing the work and private life of workers and reducing the burnout factor at the workplace. It is belived that implementation of such shortened work week is positively correlated with issues of employee productivity, equalization of social inequalities and with definining and promoting of norms related to the value of work and the individual's contribution to society. However, there are a negative side effects like a possible increase in the intensity of work. Financial side effects become the dominant point of all discussions, and are also a side effect which are stated as impossibility of comprehensive implementation in the sectors of an individual country. This paper has devoted itself to the greatest extent to these positive and negative effects, but also to the preferences of workers regarding the way and form of work and working hours. In order to collect the data necessary for this research, an online questionnaire was conducted, in which 31 respondents participated. The answers were stored and processed, and with them it was possible to confirm or refute two hypotheses, the first of which related to the existence of a significant influence of the level of education of the respondents, to the acceptance of the claim that by reducing working hours, the level of productivity increases. The same was successfully confirmed by calculating the Pearson's correlation coefficient and conducting a t-test of statistical significance. Using the mentioned methods again, the second hypothesis, which referred to the existence of a significant influence of the level of hierarchical employment of the respondents on the agreement on the statement about the impossibility of comprehensive implementation of the four-day work week, was rejected.
