This study examined the differences in stress and suicidal impulse between emotional workers and other occupation workers using the 2022 Social Survey data of the National Statistical Office. This study also identifies decision making variables that predict suicidal impulse among emotional workers. Specifically, this study investigated (1) differences in stress and suicidal impulse by job categories, (2) differences in stress and suicidal impulse among emotional workers by gender, and (3) chi-square and correlation between household income, stress and suicidal impulse by job categories. (4) decision-making variables predicting suicidal impulse of emotional workers through decision-making tree analysis. Emotional workers were shown to have higher levels of overall daily stress, family stress, and suicidal impulse compared to other occupations. However, they have relatively lower levels of job stress compared to other occupations. In addition, there was no meaningful difference in job stress and suicidal impulse by gender. Also, household income was not found to be associated with stress and suicidal impulse. As a result of the decision tree analysis, the biggest indicator of emotional workers’ suicidal impulse was family stress, followed by overall daily stress for those who did not experience family stress. Job stress did not significantly predict suicidal impulse.
