A key premise of the Leader-Member-Exchange (LMX) approach to leadership is the distinguishing relationship a leader may have with each of his or her subordinates. The following study is a result of the analysis conducted on the LMX theory since its inception 28 years ago. The critical conclusion of the analysis that is currently available determines that the LMX approach to leadership has not yet been fully specified. This conclusion was based on the fact that theorists have only focused their attention on examining the characteristics of a subsystem (the dyadic LMX relationships), without considering the whole system (context) where these relationships are formed. In an attempt to partially address this deficiency, this study will introduce a group-level model that will examine the possible effects of two predictor variables (demographic profile similarity and friendship outside the working environment) on group LMX relationships (or GLMX). This proposed model extends the traditional domain of organizational demography beyond the analysis of single demographic attributes of leaders and their subordinates by examining a demographic profile (age, team tenure, company tenure, and level of education). Moreover, the model will examine the possible effects of GLMX on group task performance (GTP) and on group organizational citizenship behaviors (GOCB). The proposed group level model includes several hypotheses. Results with respect to Hypothesis I revealed that when members of the work group were similar with respect to their leader, no relationship was found between the demographic profile and GLMX relationships. Results with respect to Hypothesis 2 indicated that when members of the work group perceived a stronger friendship outside the working environment with their leader, they also perceived a higher quality working relation with that same leader. Results did not support Hypothesis 3, it proposed that GLMX should relate positively to group task performance. Finally, results with respect to Hypothesis 4 indicated that GLMK in a work group predict supervisory perceptions of the GOCB behaviors / acase@tulane.edu
