The resource depleting effects of surface acting is well established. Yet we know less about the pervasiveness of these effects and what employees can do at work to replenish their resources. Drawing on conservation of resources theory and the ecological congruence model, we examine the extended depleting effects of surface acting and whether social interactions with coworkers (i.e., giving and receiving help) can mitigate the negative consequences of emotional labor by conducting a five-day diary study among customer service representatives (CSRs). Momentary reports from 102 CSRs indicate that within-person daily surface acting positively predicted end-of-day emotional exhaustion, and the effect of emotional exhaustion spilled over to work engagement the following day. Analyzing the within-person moderating effects of giving and receiving help at work, we find that giving help buffered the depletion process while receiving help did not. We discuss the theoretical and practical significance of considering the temporality of the resource depleting effects of surface acting, the role of at-work help giving in buffering the negative effects of emotional labor that could affect the sense of self, and the importance of resource congruence in influencing the efficacy of buffering effects.
