This study is based on an empirical study on consequences of emotions and emotional labor in the food-service industry. It analyzed the effect of emotional labor on emotions of emotional laborers and the effect of emotional labor on communication skills. Data used for analysis were collected through the questionnaire surveyed on the various samples including employees of family restaurants, Korean restaurants, Chinese restaurants, Japanese restaurants, etc. The result of data analysis indicated that only the efforts for emotional expressions among the factors influenced affirmative emotion(P-value=0.042). It also showed that the factor of the efforts for emotional expressions by researchers had a positive effect on both language communication skills and non-language communication skills(P-value=0.000). This study was valuable in the aspect that emotions and communication skills were first selected as dependent variables of emotional labor and it verified causality between emotional labor and these variables. However, it also has some limitations that its sample size was small and it depended on convenience sampling.
