1.1 Leader–member exchange
In describing supervisor–subordinate dyadic relationships, leader–member exchange (LMX) theory proposed by Graen and his colleagues explains that the relationship between a superior and a subordinate develops because of their workplace interactions (Dansereau, Graen, & Haga, 1975; Graen & Scandura, 1987; Graen & Uhl-Bien, 1995; Graen & Wakabayashi, 1994; Liden & Graen, 1980). Based on role theory and social exchange theory, the LMX framework focuses on the differentiated exchange relationships that leaders develop and maintain with subordinates within workgroups, suggesting that leaders develop differential dyadic relationships with the various group members (Graen & Uhl-Bien, 1995). Evidence from prior work demonstrates that LMX substantially influences employees’ task commitment, task performance, job satisfaction, helping behaviors, and turnover intention (e.g., Gerstner & Day, 1997).
LMX was first posited as a multi-dimensional construct by both Dienesch and Liden (1986) and Liden and Maslyn (1998) who identified the potential for “currencies of exchange” for supervisors and subordinates aside from their work behaviors. This multidimensional approach to LMX has received favorable support (Dienesch & Liden, 1986; Liden & Maslyn, 1993; Liden & Maslyn, 1998; Maslyn & Uhl-Bien, 2001). Currencies of exchange in LMX theory include affect, loyalty, and/or professional respect between members. These currencies can occur in varying “amounts” and combinations.
Studies indicate that supervisors and subordinates focus on different currencies of exchange from their partners. For example, supervisors may seek more work-related currencies, while subordinates may prefer more socially related currencies (Day & Crain, 1992; Dockery & Steiner, 1990; Liden, Sparrowe, & Wayne, 1997). Importantly, currencies are perceived, so a work-related currency is a perceived contribution, and is thus defined as the “perception of the amount, direction, and quality of work-oriented activity each member puts forth toward the mutual goals (explicit or implicit) of the dyad” (Dienesch & Liden, 1986, p. 45). On the other hand, social currencies consist of perceived affect (i.e., “the mutual affection members of the dyad have with each other, based primarily on interpersonal attraction”), perceived loyalty (i.e., “the extent to which the leader and member are loyal to one another”), and perceived professional respect (i.e., “the perception of the degree to which each member of the dyad has built a reputation within and outside of the organization”) (Dienesch & Liden, 1986; Liden & Maslyn, 1998). Consistent with the reasoning behind this research, Liden et al. (1997) argue that treating LMX as a multidimensional construct is most appropriate and characteristic of the complex leader–member relationship, and thus allows for a more complete description of its multifaceted relationships (e.g., including important individual and organizational outcomes).
As we move toward a better understanding of which aspects of LMX relationships impact various individual attitudes and behaviors, we will not only be able to further develop and refine LMX theories, but also be in a better position to fill some critical (and gaping) lacunas in the extant research. For example, past research on supervisor–subordinate dyads has suggested that demographic characteristics (e.g., gender, age, organizational tenure) can play an important role in supervisor–subordinate expectations of their LMX quality. Specifically, high tenure differences in the supervisor–subordinate dyad are associated with lower levels of psychological attachment among work group members, while a supervisor's perceptions of similarity to a subordinate is positively related to the supervisor's rating on the subordinate's performance evaluations (Turban & Jones, 1988; Turban et al., 1990). In addition, gender differences in supervisor–subordinate dyadic relationships have been found to be related to selection for international assignments (Tejeda, 2006; Tsui & Gutek, 1999; Tsui et al., 2002; Turban & Jones, 1988; Varma & Storh, 2001). We also concur with researchers who argue that more attention on LMX needs to come from the standpoint of the supervisor's point of view (Liden et al., 1997). This argument is consistent with that of Maslyn and Uhl-Bien (2001) who sees LMX relationships as a series of dyadic exchanges.
Within the framework of LMX and the Malaysian workplace, prior studies have demonstrated links between LMX quality and various work outcomes. For example, LMX quality has been found to have a positive direct impact on perceived organizational citizenship behavior and satisfaction (Bhal, Gulati, & Ansari, 2009; Ishak & Alam, 2009; Lo, Ramayah, & Hui, 2006), and organizational commitment and turnover intention (Ansari, Hung, & Aafaqi, 2007; Khong, 2009; Lo, Ramayah, Min, & Songan, 2010). From the above, and both in and out of Malaysia, we see that previous research has provided valuable evidence regarding supervisor and subordinate demographic influences on the quality of LMX. However, this same research has bypassed the critical domains of supervisor–subordinate dyadic demographic effects on leader–member exchange relationships, as well as related subordinate's work attitudes. Nor has this research examined the effects of relational demography as a proxy of cultural norms. Studies such as this one thus fill a research void in that we are capturing and measuring the LMX relationship from both the supervisor's and the subordinate's perspective (see Greguras & Ford, 2006; Liden et al., 1997; Liden & Maslyn, 1998).
