Unlocking employees' work performance in Vietnamese small and medium construction firms: exploring the impact of leadership styles, knowledge sharing and organisational commitment

This study examines the central role of leadership approaches in organisational dynamics, emphasising their impact on knowledge sharing, organisational commitment, and work performance. The research specifically focuses on the context of Vietnamese small and medium construction firms, where leadership faces unique challenges due to a rapidly growing industry, cultural diversity, and varying workforce characteristics. Employing a comprehensive research approach that combines qualitative and quantitative methods, the study conducts in-depth interviews, focus group discussions, and finally administers a survey of 327 staffs working in Vietnamese small and medium construction firms. The findings reveal that both transactional and transformational leadership styles significantly influence work performance, both directly and indirectly through knowledge sharing and organisational commitment. This research underscores the critical roles of knowledge sharing and organisational commitment as mediators between these two leadership styles and work performance, offering valuable insights for Vietnamese small and medium construction firms seeking to enhance employee performance.
