Well-being in times of ill-being : how AMO HRM practices improve organizational citizenship behaviour through work-related well-being and service leadership

Purpose: The purpose of this research is to examine the effect of ability, motivation and opportunity (AMO) practices on organizational citizenship behaviour (OCB), in medical staff working in specialized units. In addition, we check the mediating role of work-related well-being, understood as engagement, trust and exhaustion, in the relationship between AMO practices and OCB. Furthermore, the moderating role of service leadership is analysed in the relationship between AMO practices and work-related well-being. Design/methodology/approach: Using the AMO framework under the job demands-resources (JD-R) model, and based on a sample of 214 employees from public healthcare, a time-lagged moderation-mediation model was performed. Findings: Results provide evidence that AMO practices have a positive effect on OCB. Further, work-related well-being mediated the effect of AMO practices on OCB. In addition, service leadership exerted a moderating role between AMO practices and work-related well-being. Originality/value: Building on recent research which has emphasized the knowledge gap regarding how human resource practices might positively affect both employees and organizations, this is the first study that indicates that said practices positively affect both employee well-being and OCBs in the public healthcare context.
