The purpose of this study was to examine nutrition teachers` workload, job tension, and job satisfaction. Specifically, this study investigated the influence of nutrition teachers` workload and job tension on job satisfaction. A self-administered survey was distributed via online to 240 school nutrition teachers, in Korea, from July 16 to September 5, 2016. A total of 132 respondents completed the survey. The survey asked respondents for the time required for each task, job tension, job satisfaction, and demographic information. The findings of the study indicated that nutrition teachers spent most of their time on foodservice operation/ management. Among factors affecting job satisfaction, amount of work showed the lowest score. Job tension (P＜0.001) of school nutrition teachers and amount of work (P＜0.01) negatively affected their job satisfaction. Moreover `kind of work` (P＜0.001), `future of career` (0.01), and `amount of work` (0.05) were the factors significantly affecting job satisfaction. The study offers implications for governmental policies which can improve school nutrition teachers` satisfaction with their job duties.
