- Though researchers have examined racioethnic dissimilarity in the workplace, few have looked at how it relates to life satisfaction, and none have examined prospective racioethnic differences in this linkage. This study used data from a nationally representative interview survey of more than 500 people employed in the United States to test relationships between workplace dissimilarity, prejudice, racioethnicity, and life satisfaction. We found that the dissimilarity-satisfaction linkage is positive for Black and Hispanic Americans and negative for White Americans. Further exploring the latter finding, our results showed that the negative association between dissimilarity and life satisfaction was present only among White Americans higher in prejudice. This study extends the literature on interracioethnic interactions and further illustrates the importance of reducing prejudice in organizational settings.
