Job satisfaction constitutes a significant section of research because it is connected to many direct and indirect consequences of an organization. In a constantly changing environment, where the financial situation sets its own restrictions, factors which increase job satisfaction are sought without wanting to receive monetary gain. As a case study, primary data was gathered from a questionnaire filled out by the Customs Officers (public servants) of Greece. A random sample of six hundred and seventy-nine (679) public employees responded to the questionnaire. The data was processed and analyzed through the IBM SPSS (Statistical Package for Social Science) and grouped by new hyper variables, as a result of Factor Analysis. The results showed that, apart from the financial factors (in which the present study does not refer to), employees derive contentment from work participation, nature of work, value of recognition, evaluation, promotion, and good relations between colleagues and manager. The degree of satisfaction gained from each category is different, and in most cases is open to improvement. Leaders are invited to seek ways to develop each category listed above by specifying which needs the most attention and changing certain practices in place, driving to organizational change and transformation. All in all, by putting into practice the suggestions listed above, a solution can be found without added financial costs, and will ultimately benefit the work situation for civil servants, the economy, and society.
