Emotional exhaustion is the feeling that an individual′s emotional resources and related physiological resources are exhausted, which is manifested in a long-term insomnia, social withdrawal, full of fatigue and frustration, lack of energy and enthusiasm in work, etc. This kind of negative emotional reaction will lead to the decrease of employee′s job satisfaction, which will also have a negative impact on the performance of the whole organization. Service industry is a typical emotional labor, because employees must adjust their emotional behavior in order to complete organizational work effectively, so as to make their emotional expression consistent with organizational requirements. Therefore, for employees engaged in emotional work, because they need to invest the corresponding emotions in the service objects, the commercialized emotions become a commodity, which makes them more likely to produce such negative emotional experience.

These results not only expand the existing research boundary of emotional exhaustion, but also provide theoretical basis or conclusion basis for the follow-up research on related topics. In addition, the current academic research on emotional exhaustion is mainly concentrated in medical workers, teachers, police officers and other groups. However, it is the first time for this study to explore emotional exhaustion with bank tellers as samples, which constitutes the creation of this study new content.
