Which organization is responsible for investigating complaints of employment discrimination?

The Equal Employment Opportunity Commission (EEOC) is tasked with investigating complaints of employment discrimination. This federal agency enforces laws against workplace discrimination based on race, color, religion, sex, national origin, age, disability, and genetic information. The EEOC plays a crucial role in ensuring that employees' rights are protected and that employers comply with established anti-discrimination laws.

When an employee believes they have been subjected to discrimination, they can file a charge with the EEOC. The commission then investigates the complaint, gathers relevant evidence, and may issue a "right to sue" letter if they find sufficient grounds for the claim. This allows the employee to pursue legal action against the employer if necessary.

The other organizations listed have different roles: the Federal Bureau of Investigation primarily investigates criminal activity; the Department of Health and Human Services focuses on health and social services; and the National Labor Relations Board deals with labor relations and unfair labor practices. Each of these plays important roles in their respective areas but does not handle employment discrimination complaints the way the EEOC does.
