Organizations today are on the hunt for employees who are willing to engage in extra-role behaviors for the benefit of the firm. One such extra-role behavior, employee voice, has been shown in academic research and managerial applications to have a positive effect on the organization. This study moves to a group level analysis of employee voice by examining two potential determinants of group voice behavior, work unit TMX and group voice climate. In addition, the dispersion constructs of TMX differentiation and climate strength are analyzed as moderating influences on the relationships between group voice climate, work unit TMX, and group voice behavior.

After the data was collected, confirmatory factor analysis and ICCI/ICC2 were performed to test the validity of the items and the group respondent variability. Hierarchical Regression also completed for all five relationships. The results show a positive relationship between group voice behavior and its antecedents, group voice climate and work unit TMX. Climate strength and TMX differentiation were not determined to have moderating effects on the direction relationships between group voice behavior and its determinants. These results broaden the field of employee voice at the group level while still leaving some questions unanswered for future researchers to explore.
