The purpose of this study was to examine the job satisfaction of foodservice managers at schools in Jeju, Korea, according to the organizational culture and commitment of the school foodservice and administrative departments. The subjects included 144 (98.6%) dieticians from Jeju schools. The data were analyzed by descriptive analysis, reliability analysis, factor analysis, ttests, ANOVA, and Pearson's correlation coefficients, using the SPSS Win 12.0 program. In terms of organizational culture, the dieticians perceived the 'human relations model' and 'internal process model' as the strongest types for the school foodservice departments and administrative departments, respectively. However, for both types, a gap existed between the organizational culture that was perceived and that which was expected. In particular, the subjects expected that the 'human relations model' and 'open systems model' were the most important organizational culture types. In terms of the subjects' organizational commitment scores, loyalty and pride scored highest whereas unity scored lowest. For the level of job satisfaction, the performed work itself scored highest and was deemed most important. Additionally, organizational culture was positively correlated to the factors affecting organizational commitment and job satisfaction. Finally, the surveyed managers had high demands for a human relations-oriented organizational culture to enhance job satisfaction.
