This is the kiss of death. I don't work with these organizations. Diversity training must come from the whole organization through a diversity steering committee made up of employees from a representative cross-section of the organization. The organization does not understand the connection between diversity and the bottom line. I want to emphasize that these are good and valid reasons but in corporate America, make the business case for diversity training first.
Training is all the organization is doing.
The organization is not reviewing or scrutinizing their hiring, promotion, leadership development, and business practices. Management's lack of participation is all the evidence the rest of the organization needs to resist the training and consider it the next fad - They will wait and it will pass. The training fails because participants were not engaged, not interested, and did not find the training practical, pertinent and compelling. Training is being developed and lead solely by external diversity consultants and trainers. The training is thus the consultant's program and not a program developed by the employees of the organization, for the organization.
