Leader-Member Exchange (LMX) theory posits that the relationship quality between leaders and their subordinates significantly influences various aspects of the workplace, including employee satisfaction, retention, and overall performance. The primary purpose of this research is to analyse the effects of high-quality LMX relationships on job satisfaction, career development, and employee retention. Recognising the vital role of effective leadership in enhancing employee engagement and organisational performance motivates this study. As workplaces become increasingly complex, understanding LMX dynamics is crucial for developing strategies to improve satisfaction and retention. The study aims to fill gaps in existing literature to inform future research and practical applications. Employing a qualitative approach, this study conducts a comprehensive literature review of existing research on LMX theory. It synthesises theoretical models, empirical studies, and case analyses to robustly understand LMX relationships and their implications in diverse organisational contexts. The literature reveals that high-quality LMX relationships characterised by mutual trust, support, and respect significantly impact employee satisfaction and retention. Employees with solid leader relationships report higher job satisfaction and commitment, leading to improved performance and lower turnover rates. The findings underscore the need for leaders to enhance trust and support within their teams through recognition and career development opportunities. Organisations prioritising these elements will likely experience increased employee satisfaction and performance, fostering a positive workplace culture.
