Purpose: The purpose of the paper is to examine the levels of job satisfaction among doctors who work in Greek public hospitals, to determine the factors that may influence their satisfaction, to examine the contribution that staff support makes to job satisfaction and to investigate the potential impact that an economic recession might have on job satisfaction. Design/methodology/approach: The sampling process used was stratified sampling and it was applied to all health regions in Greece. An official request to carry out the study was sent to 45 hospitals for the approval of their management. Through random sampling, 5% of the doctors' population was selected from each participating hospital, with the resulting sample consisting of 458 doctors from all the health regions of Greece. An anonymous questionnaire was administered to the sample of medical doctors to gather data on their perception of the work they do in public hospitals. Findings: Empirical results showed that (1) the most important factor in doctors' job satisfaction appears to be the nature of their job and the high levels of autonomy that they have, and (2) doctors' level of commitment is maintained by enhancing their positive emotions and sense of professional well-being. Originality/value: A deeper understanding of important concepts of an organization's behavior such as job satisfaction, staff support and their connection with internal organizational structures will facilitate policy makers and those who make decisions on the strategic management of medical staff in public hospitals.
