The influence of shift work on emotional exhaustion in firefighters: The role of work-family conflict and social support

摘要

Purpose - With the demand for continuous services increasing, organizations have relied more upon shift work to adapt to the needs of consumers. However, relatively little research has adequately explored the effects of different types of shifts on emotional exhaustion, particularly as they relate to work-family conflict and social support. In this paper based on the conservation of resources (COR) model of stress, a mediated model where shifts that demand more resources related to the work-family interface will be more likely to lead to emotional exhaustion is argued. The paper aims to address this issue. Design/methodology/approach - A study of 168 fire service personnel from departments working on three different shift systems is conducted. The participants complete survey measures of emotional exhaustion, work-family conflict, support, and demographic controls. Findings - The paper suggests that more demanding shifts, those that lead to less time spent off the job in continuous blocks, are associated with higher work-family conflict. Moreover, family support can make up for the lost resources of demanding shifts and is negatively associated with work-family conflict. Finally, higher work-family conflict is associated with emotional exhaustion. Practical implications - The paper has important implications for the scheduling of shifts and employee well-being. Specifically, it suggests that scheduling shifts with larger continuous blocks of time with family will be associated with lower work-family conflict and less strain on employees. Originality/value - The paper is the first to use a COR-based framework to understand how shift scheduling leads to decrements in employee well-being. Given the common use of shift work in practice, such findings may be critical in effective shift work design such that shifts have less negative impact on family life and less longer term impact on employee strain.
