This study analyzes the causal relationship by assuming that emotional labor and work load are factors affecting the burn-out of care service workers who have provided care services in the context of the spread of COVID-19. In addition, the factors affecting emotional labor and work load on burnout were classified into two models, a private and a public agency, and the differences were investigated. In order to achieve this research purpose, a self-reported survey was conducted targeting 300 employees of care service workers located in Gyeong-nam. Of these, 232 cases were analyzed. The main research results are as follows. First, there was a difference in emotional labor, work load, and burn-out between public and private. Second, the factors affecting burn-out in private were emotional labor and work load. It was found that the factors affecting burn-out in public were average monthly income, emotional labor, and work load. Third, it was found that age, career, emotional labor, and work load were the factors influencing the burnout of care workers. Based on these research results, emotional labor, work load, mental health service linkage plan to solve emotional labor problems, and burnout prevention program were suggested.
