In order to accomplish the purpose of this study, we derived the multiple role commitment of married female flight attendants, the job performance, the emotional labor parameter, and the psychological well - being, the control variable, based on the previous research. After that, the questionnaire was used for empirical analysis and it was conducted for a married female flight attendant working on an international flight of K and A Airlines, a Korean national full service carrier (FSC) airline. A total of 394 responses were used for data analysis. As a result of this research, it was found that family role, friend role, community role, and job role, which are sub - factors of multi - role commitment of married female flight attendant have significant influence on emotional labor. In addition, the role of community and job role only had a significant effect on job performance in relation to multiple role commitment and job performance. In the relationship between emotional labor and job performance, deep acting of emotional labor affects job performance. In the mediating effect of emotional labor, emotional labor acts as a parameter in the relationship between family role and job performance. Other friends, community, and job roles did not have mediating effects. In the moderating effect of psychological well-being, the psychological well-being was shown to have a significant moderating effect only in the relationship between the roles of multiple roles and emotional labor, and the results of the other family, friends and community roles were not significant.
