Service-oriented high-performance work systems and service-oriented behaviours in public organizations: the mediating role of work engagement

Service orientation in the HRM system is a lever for public employees to serve the public even beyond their work roles. Our research seeks to understand how work engagement links service-oriented high-performance work systems (HPWSs) to public employees' service-oriented behaviours. Employees and their managers from public legal service agencies in the Vietnamese context were recruited as participants in our research project. The research results demonstrated the role of employee work engagement in mediating the relationships between service-oriented HPWSs and service-oriented in-role performance as well as service-oriented organizational citizenship behaviour (OCB). The interactions were also found between service-oriented HPWSs and HRM system strength, as well as between service-oriented HPWSs and public service motivation in catalysing work engagement.
