Boris is the director of talent management at a laboratory. At a staff meeting, when he suggests allocating more funds for diversity training, one of his peers disagrees. "We've already had sensitivity training about racism in the workplace, and we participated in a job fair that encourages women to pursue careers in science and technology," the coworker says. "And we haven't had much employee turnover this year, so there's no need to budget for additional diversity training next year." What is the best way for Boris to respond to these comments?
