This paper presents findings from a workshop focused on the physical, social and organizational work environment in the service department on board Swedish passenger vessels. Twentyseven maritime professionals participated to provide input to potential causes and measures for long-term sick leave. During the workshop, an affinity diagram was created to systematically order the input of the respondents. The results show a wide range of causes and potential measures across multiple organizational levels. Unclear leadership, ambiguous or high demands with limited decision latitude, as well as aspects of work organization, i.e. manning, pressure for effectiveness, and extensive working hours were identified as important contributors to long-term sick leave. Although the findings are based on a workshop with Swedish maritime professionals, the results may be transferable to the international maritime sector to gain a deeper understanding of how to create, organize and promote a safe and efficient work environment.
