The synergistic effects of LMX and procedural justice climate on employee motivation and customer loyalty in a retail service context

Purpose The aim of this paper is to test how leader–member exchange (LMX) interacts with procedural justice climate to influence three types of employee motivation (i.e. achievement striving motivation, status striving motivation and communion striving motivation). Furthermore, this study empirically examines the indirect effects of LMX on customer loyalty through employee motivation and service orientation. Design/methodology/approach This study used a matched sample of 188 retail service employees and 376 customers from a large shopping mall in South Korea to test the empirical model. Structural equation modeling (SEM) and bootstrapping method were employed to test a series of proposed hypotheses. Findings The results show that LMX significantly enhances customer loyalty through two motivational dimensions and service orientation. In particular, this study shows that achievement and status striving motivation are directly related to service orientation, but communion striving motivation does not affect customer-focused service attitude. In addition, procedural justice climate serves as a critical moderator and synergistically interacts with LMX to influence achievement and status striving motivation. Research limitations/implications This study offers new insight regarding how managers' roles in both individual (leader–member exchange) and organizational (procedural justice climate) level affect different forms of retail service employee motivation and service orientation, which in turn, result in customer loyalty. Practical implications The results suggest that when retail service employees perceive procedural fairness at retail stores, they are more motivated to work hard to complete their assignments and achieve their sales goals in conjunction with leader support. Therefore, managers must provide a clear guideline and procedure regarding salary raises and performance evaluations or engage in thorough discourse on such matters with employees prior to announcements of such decisions. Moreover, as retail service employees interact with customers in the frontline, and how they serve customers plays a key role in creating customer loyalty. Managers should encourage retail service employees to engage in service-oriented behaviors. Originality/value The results suggest that LMX facilitates more formal task-related motivation to achieve either tasks or status while it is less related to relationship-building motivation, which is a unique contribution of this study. The results offer better understating of how LMX differentially leads to specific types of employee motivation in the existing literature.
