Purpose : This study analyzes the introduction and evolution of the occupational health manager system in South Korea from 1994 to 2024 and defines their roles by identifying key attributes, antecedents, and outcomes. Methods : The study used Walker and Avant's (2019) concept analysis method to analyze domestic literature and academic journals published between 1994 and 2024. A total of 9 studies were chosen from an initial set of 518. To address the research limitations, the study also examined policy documents and government reports, expanding the reference pool with additional keywords. Results : The roles of occupational health managers have expanded from focusing on preventing occupational diseases and industrial accidents to including mental health management, infectious disease prevention, and support for multicultural workers. Key attributes include planning skills, health promotion program management, collaboration, psychological support, and the ability to respond to infectious diseases. Conclusion : Occupational health managers play a crucial role in protecting workers' health and strengthening occupational health systems. Systematic education, better qualifications, workforce expansion, and policy support are necessary. This study provides a foundation for enhancing their roles and guiding future policy development.
