The federal equal opportunity law, Title VII of the Civil Rights Act of 1964, makes it unlawful for an employer of 15 or more employees to refuse to hire, discharge, or take action affecting an employee’s compensation, terms, conditions, or privileges of employment because of the employee’s race ( 42 USC 2000e-2(a) ). The Equal Employment Opportunity Commission (EEOC) has issued enforcement guidance to assist employers to prevent this form of discrimination and has launched an initiative known as "E-RACE" to strengthen enforcement of Title VII. Notices regarding Title VII's protections and prohibitions must be posted in the workplace. Preventative measures include training and taking immediate and effective action when discrimination occurs. Another federal law, Section 1981 of the Civil Rights Act of 1866, prohibits public and private employers from discriminating on the basis of race.
