Work engagement was recognized as a key factor in improving performance, innovation, and organizational success amid the complexities of global dynamics. Global data showed low engagement levels, with only 23% of employees feeling engaged in their work. Affective commitment, as the emotional attachment of employees to their organization, emerged as a primary predictor of sustained engagement. This study aimed to systematically examine the role of affective commitment in enhancing work engagement and to explore its mediating relationship with organizational factors such as leadership style and work climate. Using a Systematic Literature Review (SLR) approach, the study analyzed 30 articles from Scopus, Web of Science, and Google Scholar, following the PRISMA protocol. The findings revealed that affective commitment served as a direct predictor, a mediator in the relationship between ethical and servant leadership with engagement, and a buffer against stress and turnover. Furthermore, organizational factors such as high-involvement work practices and an ethical climate were found to reinforce affective commitment. The study’s practical implications emphasized the importance of value-based human resource development strategies, the strengthening of ethical leadership culture, and the creation of a supportive work environment to foster sustainable engagement and improve organizational competitiveness in the modern era.

Metode penelitian menggunakan pendekatan Systematic Literature Review (SLR) terhadap 30 artikel dari database Scopus, Web of Science, dan Google Scholar, dengan proses seleksi mengikuti protokol PRISMA.
