The Colorado Fair Employment Practices Act makes it illegal for an employer to discriminate on the basis of race, religion, color, age, gender, disability, national origin, and ancestry. The statute covers employers of any size: if your workplace has between 1 and 14 employees, you should file with the State Division of Civil Rights, as the EEOC enforces federal law, which covers only employers with 15 or more employees (or 20 in the case of age discrimination).
