Abstract: Leadership engenders an essential element for organisations to develop business strategies and achieve their goals. This research aims to examine the impact of laissez-faire leadership style on Organisational Commitment (OCOM) in health care centers in Qatar. The researcher adopted a quantitative approach using a self-administered questionnaire to collect the primary data. The sample consisted of 218 leaders and supervisors from five healthcare centers in Qatar selected employing non-random sampling. The study indicated a significant positive relationship existed between laissez-faire leadership and OCOM. Moreover, leadership behavior significantly impacted OCOM behaviors but in different degrees: continuance commitment and normative commitment to a higher extent and affective commitment less so. Also, the results showed the percentage to which Laissez-Faire leadership style was practiced in the sample to be high.
