Final answer:
The EEOC investigates employment discrimination and may bring a lawsuit on behalf of a private complainant.
Step-by-step explanation:
The Equal Employment Opportunity Commission (EEOC) is responsible for investigating employment discrimination and protecting workers who file complaints against employers. When a private complainant files a complaint with the EEOC, the EEOC evaluates the complaint to determine if it merits further action. If the EEOC decides to pursue legal action, it may choose to bring a lawsuit against the employer on behalf of the complainant.
