Employment discrimination provisions of the act apply to companies with more than 15 employees and define two broad types of discrimination, disparate treatment and disparate impact. Disparate treatment is fairly straightforward: It is illegal to treat someone differently on the basis of race or national origin.
For example, an employer cannot refuse to hire an African-American with a criminal conviction but hire a similarly situated white person with a comparable conviction.
Disparate impact is more complicated. It essentially means that practices that disproportionately harm racial or ethnic groups protected by the law can be considered discriminatory even if there is no obvious intent to discriminate. In fact, according to the guidance, evidence of a racially balanced work force will not be enough to disprove disparate impact.
As the E.E.O.C. establishes in its guidance, members of some minority groups are much more likely to be arrested and convicted than whites. From the commissions perspective, the Civil Rights Act serves to make certain that disparity is not compounded in the workplace.
