All of the laws we enforce make it illegal to fire, demote, harass, or otherwise "retaliate" against people (applicants or employees) because they filed a charge of discrimination, because they complained to their employer or other covered entity about discrimination on the job, or because they participated in an employment discrimination proceeding (such as an investigation or lawsuit).
For example, it is illegal for an employer to refuse to promote an employee because she filed a charge of discrimination with the EEOC, even if EEOC later determined no discrimination occurred.
The law forbids retaliation when it comes to any aspect of employment, including hiring, firing, pay, job assignments, promotions, layoff, training, fringe benefits, and any other term or condition of employment.
