Satisfied employees show a higher level of work efficiency, which has a positive effect through different elements on the organizational functioning in general. It is desirable that the whole organizational system is shaped in such manner to have a positive effect on each of the employees and that it contributes to the creation of a pleasant organizational climate. The intent of this thesis is to explore how some of employees’ socioeconomic characteristics are related to their satisfaction with the work they do. The research has surveyed 100 people, using an online survey. After the statistical analysis of the information gathered it is possible to claim that two out of five research hypotheses set by the previous researches have been confirmed. Hypotheses about the difference in job satisfaction among people of different age groups and among the people with different income levels have been confirmed (in general younger people are more satisfied, as well as people with higher income) ,while there is no difference in the evaluation of the overall job satisfaction in regards to the gender, level of education and marital status.
