In our 2009 Academy of Management & Education article, we argued that business students should receive mandatory diversity education to help prepare them for increasingly diverse environments (Bell et al., Academy of Management Learning & Education 8:597–609, 2009). Central to our thesis were persistent discrimination against and resulting inequalities among non-dominant group members, including women, racial and ethnic minorities, and people living with disabilities. Although there has been some progress since the article was published, we have experienced retrenchment and resurgence in some areas. In 2021, The Equal Employment Opportunity Commission (EEOC) received 61,000 discrimination complaints, and the videotaped murder of George Floyd in 2020 shocked the nation, laying bare the work that educators must continue to prepare our students to become better citizens. Overt resistance to diversity education, through executive orders and state legislation, and shifts in the sociopolitical environment, make the need for such education more apparent. In this paper, we revisit select arguments from our 2009 article to examine the progress diversity educators and scholars have made and discuss what we must do to make diversity education for business students a reality.
