DEI meaning in Business ?

The "business case for diversity" stems from the progression of the models of diversity within the workplace since the 1960s. The original model for diversity was situated around affirmative action drawing strength from the law and a need to comply with equal opportunity employment objectives implemented in the Civil Rights Act of 1964. Equal employment opportunity was centered around the idea that any individual academically or physically qualified for a specific job could strive for (and possibly succeed) at obtaining the said job without being discriminated against based on identity. This compliance-based model gave rise to the idea that tokenism was the reason an individual was hired into a company when they differed from the dominant group. Dissatisfaction from minority groups eventually altered and/or raised the desire to achieve perfect employment opportunities in every job.

The social justice model evolved next and extended the idea that individuals outside the dominant group should be given opportunities within the workplace, not only because it was instituted as a law, but because it was the right thing to do. Kevin Sullivan an ex-vice president of Apple Inc. said that "diversity initiatives must be sold as business, not social work." This model still revolved around the idea of tokenism, but it also brought in the notion of hiring based on a "good fit".

In the deficit model, it is believed that organizations that do not have a strong diversity inclusion culture will invite lower productivity, higher absenteeism, and higher turnover which will result in higher costs to the company. Establishments with more diversity are less likely to have successful unionization attempts.
