Although religious discrimination in U.S. workplaces appears to be rising, little is known about how different groups of employees perceive discrimination. Here, the authors draw on 194 in-depth interviews with Muslim, Jewish, Christian, and nonreligious employees to examine perceptions of religious discrimination in the workplace. The authors identify several common modes of perceived discrimination, including verbal microaggressions and stereotyping, social exclusion and othering, and around religious holidays and symbols. The authors also find that Christians tend to link perceived discrimination to personal piety or taking a moral stand in the workplace, while Muslims, Jews, and nonreligious people tend to link discrimination to group-based stereotypes and describe a sense of being seen as religiously foreign or other. This study reveals the value of studying groups alongside one another for the fullest picture of workplace religious discrimination and points the way toward further sociological research of how both majority and minority groups perceive discrimination.
