“…Here we adopt the relational perspective and focus on an employee's dissimilarity from peers in a work group; we believe this allows us to explain how diversity affects work related outcomes at the individual level (Chattopadhyay, Tluchowska, et al, 2004;Guillaume et al, 2012;Joshi et al, 2011;Riordan, 2000;Tsui & Gutek, 1999;see also, van Knippenberg & Schippers, 2007) and how these effects interact with individual, group, organizational, and societal factors (Brodbeck et al, 2011;Joshi et al, 2011). We suggest that the work group rather than the organization should be the focus here because it is likely to be the most salient unit, the most likely focus of attachment, and the most important instance for control, and might therefore be also the best predictor of employee innovation, effectiveness, and well-being (Riketta & Van Dick, 2005;van Knippenberg & Schie, 2000).…”
