This field study examines the joint effects of social exchange relationships at work (LMX:leader-member exchange and TMX: team-member exchange) and employee personality Existing research has demonstrated the importance of personality characteristics and social exchange relationships as predictors of task and citizenship performance (Barrick & Mount, 1991;Eisenberger, Fasolo, & Davis-LaMastro, 1990;Judge & Ilies, 2002;LePine & Van Dyne, 2001;Settoon, Bennett, & Liden, 1996). To date, however, consideration of personality characteristics and social exchange relationships as predictors of employee performance has been addressed in two predominantly separate literatures. Additionally, while teams are increasingly important in organizations (Ilgen, 1999) and the construct of team member exchange was introduced over fifteen years ago (Seers, 1989), we are aware of no research that simultaneously examines leader member exchange (LMX) and team member exchange (TMX) relationships as predictors of employee task and citizenship performance.Emphasizing the benefits of integrative research that simultaneously considers personality and social exchange predictors of performance, this field study has two primary purposes. First, we develop and test theoretical arguments that two personality characteristics (conscientiousness and agreeableness) and two social exchange relationships (LMX and TMX) interact to predict task performance and helping behavior of professionals working in teams.More specifically, based on Trait Activation Theory (Tett & Burnett, 2003), we propose and demonstrate interactions where high quality social exchange relationships weaken the positive effects of personality on performance. Second, drawing on Ajzen's (1988) principle of compatibility, we argue that LMX has special relevance to behaviors targeted at the supervisor and TMX has special relevance to behaviors targeted at coworkers. Thus, we extend past research that has demonstrated differential effects of LMX and Perceived Organizational Support (POS: Masterson, Lewis, Goldman, & Taylor, 2000: Settoon et al., 1996 by considering interactive effects of personality and LMX in predicting outcomes targeted at the supervisor as 4 well as interactive effects of personality and TMX in predicting outcomes targeted at peers.We first define task and citizenship performance. We then consider personality and quality of exchange relationships as predictors of task and citizenship performance. Finally, we integrate work on personality and exchange relationships, arguing that quality of exchange relationships moderates the effects of personality on task and citizenship performance.
Task Performance and Citizenship PerformancePerformance is a complex, multi-dimensional construct (Campbell, 1999). As such, finegrained conceptualizations can provide a better understanding of relationships between specific predictors and specific aspects of performance (Hogan & Holland, 2003;Johnson, 2001;Podsakoff, MacKenzie, Paine, & Bachrach, 2000;Rotundo & Sackett, 2002...
