As the service industry continues to grow, so do the number and the diversity of service providers. The types and intensity of emotional consumption and emotional labor experienced by service providers are increasing. This study intends to suggest Co-Creation(C.C) as a way to approach the service provider's point of view and to make them less aware of negative emotions in the service process and to improve job satisfaction. In the past, C.C was considered the benefits from a consumer’s perspective in designing, developing, manufacturing and delivering products and brands. This study extends the past study and intends to examine C.C from the perspective of service providers by applying C.C to the interaction process of producing and delivering services. The purpose of this study is to suggest that the customer orientation of service providers affects the service behavior in the pre-C.C stage and the service behavior during the C.C process. In addition, the service behavior in the pre-C.C stage and the service behavior during the C.C process will affect positive and negative emotions of service providers and consequently the job satisfaction. The empirical results of the beauty service providers are as follows. The customer orientation of beauty service providers was found to have a significant effect on pre-C.C behavior and behavior during the C.C process. Pre-C.C behavior was found to have a significant effect on the behavior during the C.C process. Behavior during the C.C process had a significant effect on positive emotions, but not on negative emotions. Lastly, positive and negative emotions had a significant effect on job satisfaction.
