01 / The answer
The short answer
Since 1 January 2026, HB 3773 (Public Act 103-0804) makes it a civil rights violation under the Illinois Human Rights Act for an employer to use AI that has the effect of discriminating on the basis of a protected class in recruitment, hiring, promotion, renewal, training or apprenticeship selection, discharge, discipline, tenure or terms of employment. Employers may not use ZIP codes as a proxy for protected classes, and must notify employees when they use AI for these purposes. The Department of Human Rights must adopt rules on the timing and means of notice.
