In the context of Ghana's emerging economy, the interrelationships between talent management, corporate governance, and employee engagement are pivotal for organizational success. This study investigates the mediating effects of organizational ethics on these relationships in selected public institutions in Ghana. The Ethical Climate Theory provides a robust theoretical foundation for this study. Adopting a cross-sectional design, and a quantitative research approach, and a purposive sampling technique, data were collected from HR managers and senior executives across various sectors using structured questionnaire. 15 public Universities were purposively sampled out of 25 public Universities in Ghana. The results, analysed through Structural Equation Modelling (SEM), reveal significant direct relationships between talent management, corporate governance, and employee engagement. Moreover, organizational ethics significantly mediate these relationships, enhancing the positive impacts of talent management and corporate governance on employee engagement. These findings underscore the critical role of ethical practices in fostering a positive organizational climate and enhancing employee outcomes. By integrating ethical principles into management practices, organizations can enhance employee engagement and achieve sustainable performance outcomes. The study provides valuable insights for organizational leaders and policymakers aiming to integrate ethical principles into management practices, thereby promoting sustainable development and economic growth in Ghana. Future research should consider longitudinal study to establish causal relationships and explore the role of organizational ethics in different cultural contexts.
