 While there is some debate about whether discrimination in employment should be legally prohibited (see Epstein 1992), almost everyone agrees that it is morally wrong (Hellman 2008; Lippert-Rasmussen 2014). Discussion has focused on two questions. First, when does the use of a certain criterion in an employment decision count as discriminatory? It would seem wrong if Walmart were to exclude white applicants for a job in their marketing department, but not wrong if the Hovey Players (a theater troupe) were to exclude white applicants for the role of Walter Younger in A Raisin in the Sun. We might say that whether a hiring practice is discriminatory depends on whether the criterion used is job-relevant. But the concept of job-relevance is contested, as the case of “reaction qualifications” reveals. Suppose that white diners prefer to be served by white waiters rather than black waiters. In this case race seems job-relevant, but it seems wrong for employers to take race into account (Mason 2017). Another question that has received considerable attention is: What makes discrimination wrong? Some argue that discrimination is wrong because of its effects on those who are discriminated against (Lippert-Rasmussen 2014); others think that it is wrong because of what it expresses to them (Hellman 2008).
