The study used questionnaire survey research to examine the relationship among self-monitoring (SM), emotional labor (surface acting and deep acting) and employee positive affective delivery (EPAD) with a sample of 303 first line employees, and the response rate was 86.57%. The results revealed that SM influenced surface acting and deep acting positively; surface acting and deep acting both affected EPAD negatively and positively respectively; but SM did not affect EPAD. However, the results of path analysis revealed the surface acting and deep acting negatively and positively mediated the relationship between SM and EPAD. The authors discussed the implications for theory and practices, and suggestions for the further study.
