This study examines the link between supervisor‐subordinate dissimilarity and associated perceptions of discrimination and exclusionary treatment. Using a sample of 1,059 employees from a large Southeastern insurance company, we examined age, race, and gender dissimilarity as predictors of perceived discrimination, supervisory support, and leader‐member exchange. In addition, we examined supervisor liking/attraction and status of affiliation with supervisor as intervening variables. Race dissimilarity related positively to perceptions of discrimination and exclusionary treatment, mediated by both supervisor liking and status. Effects for age and gender dissimilarity were nonsignificant. We discuss the importance of these findings for understanding and managing dyadic relationships at work. Copyright © 2013 ASAC.
