The impact of self-directed learning on middle management job performance: mediating role of explicit knowledge internalization in Macao’s casino-integrated resorts

Purpose – This study aims to explore the relationships among self-directed learning (SDL), explicit knowledge internalization (EKI) and job performance in middle management within Macao’s casino-integrated resorts. It examines how SDL and EKI enhance job performance in this unique setting. Design/methodology/approach – A conceptual framework was empirically tested using survey data from 380 middle managers. An exploratory single-case study approach validated the proposed relationships among SDL, EKI and job performance in Macao’s casino-integrated resorts. Findings – The results indicate that both SDL and EKI significantly influence job performance. EKI also mediates the relationship between SDL and job performance, emphasizing its role in knowledge assimilation and application. Research limitations/implications – The focus on Macao’s casino-integrated resorts may affect generalizability. Future research should investigate diverse contexts to further validate the results. Practical implications – It offers guidance for enhancing job performance through knowledge management strategies, focusing on SDL and EKI. Human resource practitioners and leaders can use these insights to tailor learning and development programs, promoting a culture of continuous improvement and knowledge sharing. Originality/value – This research highlights how SDL and EKI boost job performance in casino-integrated resorts. By framing these resorts as learning organizations, this study offers insights into the role of learning and knowledge sharing in organizational success.
