The Differential Effect of Ego-Resiliency on the Relationship between Emotional Labor and Salivary Cortisol Level in Bank Clerks.

Elevated stress levels in emotional laborers has been documented in a number of studies. To minimize the negative effects of stress, the need to examine potential protective factors has been highlighted. The primary purpose of this study was to investigate the differential moderating effect of ego-resiliency on the relationship between emotional labor and salivary cortisol level by comparing two groups of bank clerks deemed to experience different degree of emotional labor. Twenty-four bank clerks working in regional branch offices who provided face-to-face customer service (customer service group) and 33 administrative-duty bank clerks who work without face-to-face customer service (administrative work group) were recruited to participate in the study. Participants were asked to draw saliva into a specimen tube at an identical time during a work day and complete self-report scales measuring emotional labor and ego-resiliency. Hierarchical multiple regression analyses were conducted to examine the interaction effect of ego-resiliency on the relationship between emotional labor and salivary cortisol level by controlling for gender, age and education level as covariates. The results demonstrated that the degree of emotional labor reported by the customer service group was higher than that of the administrative work group. Furthermore, ego-resiliency moderated the relationship between emotional labor and cortisol levels in the customer service group but not in the administrative work group. The implications and limitations of this study are discussed along with suggestions for future research.
