Illinois HB 3773: AI in employment (Illinois Human Rights Act)
Illinois employers may not use AI that discriminates in hiring or other job decisions, and must tell workers when AI is used. In force since 1 January 2026.
HB 3773 (Public Act 103-0804) amends the Illinois Human Rights Act. It is a civil-rights violation for an employer to use AI that has a discriminatory effect on protected groups in recruiting, hiring, promotion, discipline, dismissal or other terms of employment, to use zip codes as a stand-in for protected traits, or to fail to notify employees that AI is being used.
The Department of Human Rights proposed notice rules in May 2026. Law firms tracking the rules report that it temporarily withdrew them in June 2026 without a new timeline (the department’s page has not been updated), so the notice duty currently applies without detailed rules.
