The Inter-Pacific Railroad employs Francisco McGregor, a Hispanic man, as a supervisory conductor on its commuter trains. Except for one white woman, all of the other supervisory conductors employed by Inter-Pacific were black men. Francisco’s Spanish nickname is “Paco.” The other supervisor conductors referred to Francisco as “Taco.” They used racial slurs, such as “beanbag,” when talking about him to other employees. Francisco complained to the senior trainmaster and threatened to file a claim with EEOC. What would you suggest the trainmaster do to address Francisco’s concerns and prevent him from filing a claim with the EEOC?
