Employee growth is an essential component of the success of an organization, particularly in healthcare, where nurses play an essential position in providing high-quality treatment to patients.  The purpose is to investigate the impact that work discipline, work stress, leadership conduct, and work motivation have on employee growth. The study focuses on 385 nurses and uses employee performance as a mediating factor. Quantitative research used structured surveys and statistical models to assess data.  Work discipline and leadership conduct improve employee performance and development, according to the research.  Work stress significantly impacts employee performance and development; hence, stress management is necessary to maintain worker efficiency.  Professional advancement and job happiness were also influenced by work motivation and conduct. These findings emphasize the need for a disciplined, motivated, and well-supported nursing workforce to improve healthcare performance.  Strategic leadership, stress management, and motivation-boosting policies are needed to grow employees and improve performance.
