This paper examines the relationships among the psychological contract, fairness, OCB, and customer service. We report on two exploratory studies that provide insight into psychological contract violations and subsequent perceptions of fairness, as well as OCB activity. A linkage is made between psychological contracts and behavior directed internally and those directed externally (i.e., customer service). We extend the current theory to suggest implications for effectively managing customer service employee OCB. Finally, suggestions are made for both practice and future research to be conducted in a multidisciplinary design.
