    Although fatigue is considered an important problem in shipping, little is known about potential mitigating factors or resources for coping. Adopting a Job Demands–Resources framework, this article examines the effects of both job demands (stressors) and resources on fatigue, focusing on social interactions on board as a potential source of social support. Using an incomplete repeated-measures design, the study combined information from documents with surveys on seven cargo ships. Findings indicated that fatigue levels were highest for those working on deck and for individuals at higher hierarchical levels. Higher numbers of port calls (and to some extent lower numbers of days at sea) also increased fatigue levels. By contrast, night watches and the number of days in port had no effect on fatigue. Supportive social interactions reduced fatigue (main effect), but their effect was weaker when the number of port calls increased (interaction effect). All main effects were mediated by individuals’ perceptions of work pressure. Taken together, findings highlight the importance of considering social interactions on board to advance our understanding of stressors and strain in seafaring

    Social networks and resilience in work teams

    This chapter explores social networks and resilience in an organizational context, focusing on work teams and their strategies for preparing, managing and learning from adversities. To date, only few studies have considered social networks in relation to the resilience of individuals and teams in organizations. This chapter shows how a social network perspective contributes to our understanding of team resilience. Specifically, it proposes that for research on team resilience, social networks can be relevant in three ways: they provide resources, they offer a way of analyzing responses to adversity, and they are important outcomes. Organizational design and interventions play a key role for resilience by influencing team members' networks, as well as the resources and strategies available to them. Future studies should take a holistic approach to explore team processes in response to adversities over time, taking into account the multilevel context in which teams are embedded

    ‘Only work and sleep’: seafarers’ perceptions of job demands of short sea cargo shipping lines and their effects on work and life on board

    Previous research on job demands in seafaring has focused on the effects of workload and circadian disturbance on seafarers’ health and fatigue. Taking a more comprehensive approach, this study identifies job demands of short sea cargo shipping lines and explores their effects on work and life on board. Data came from 54 interviews with officers and crew on five cargo ships. Findings revealed job demands related to characteristics of the schedule, ports, and sea voyages; these were not only associated with workload and circadian disturbance, but also with the difficulty of the work, the ability to plan ahead, and intrusions from third parties. Job demands affected outcomes through two interconnected processes. First, job demands had direct and indirect effects on fatigue and the working climate on board. Second, potential positive effects of job demands (i.e. interesting work and pay) were related to motivation and, together with a good working climate, could reduce turnover. Connecting the two processes, a good working climate was pivotal in counteracting negative emotions and supporting motivation and collaboration. In this way, it functioned as a key resource. External constraints could either buffer or reinforce these effects
