When an internal checklist isn’t completed and a compliance deadline approaches, HR departments experience a certain kind of silent panic. It’s safe to say that this sentiment has been circulating among Illinois employers for some time. A major amendment to the Illinois Human Rights Act went into effect on January 1, 2026, and it specifically addresses how businesses use AI to make hiring decisions. Additionally, it appears that many organizations are still catching up.
Governor Pritzker signed the legislation in August 2024, but it does more than simply push employers in a different direction. It makes a clear line. Employers must now inform workers that they are using AI to help with hiring, promotions, discipline, terminations, and determining the terms of employment. Beyond disclosure, the law forbids the use of AI in any manner that leads to discrimination against protected classes. It goes farther than most people anticipated, stating that zip codes cannot be used as a stand-in for protected traits. Just that particular detail demonstrates how seriously lawmakers were considering how algorithmic bias actually functions in real-world situations.
The scope of this law sets it apart from nebulous, aspirational tech policy. It is applicable to any business that operates and has at least one employee in Illinois for 20 or more calendar weeks in a given year. Whether or not the business has a physical office in the state is irrelevant. Furthermore, it makes no difference if the AI tool was developed internally or acquired from a third party. You are protected if you use it on employees in Illinois. Some multi-state employers have been caught off guard by this reach, especially those who thought their headquarters location would shield them from state-level obligations.
It is worthwhile to take a moment to consider this law’s definition of artificial intelligence. It is intended to be broad. Any machine-based system that produces forecasts, suggestions, or choices that affect employment outcomes is covered by the amendments. This includes generative AI, which creates job descriptions, evaluates resumes, or compiles candidate evaluations from video interviews. It’s possible that some employers were unaware that the screening tool their ATS vendor subtly integrated or the scheduling software they purchased two years ago now fit this description. It’s not a theoretical worry. Compliance teams are currently discreetly stress-testing this kind of thing.
Things get a little murky when it comes to the notice requirement, and to be honest, that ambiguity makes sense considering how quickly this space is developing. The Illinois Department of Human Rights is required by law to establish precise guidelines regarding the manner and timing of notice delivery. These regulations are still in the works. Employers are left to draft notices in the interim without a precise template, which is difficult for any legal team. Whether a single disclosure during onboarding will be adequate or if continuous notifications will be needed each time an AI-assisted decision is made is still up for debate.
Instead of using private litigation, enforcement is handled by the Human Rights Commission and the Illinois Department of Human Rights. Since there is no private right of action, the immediate legal risk may be somewhat mitigated, but the reputational risk associated with being found in violation remains. Furthermore, Illinois is less of an anomaly and more of a sign of the direction that employment law is taking nationally, since California is actively considering its own wave of AI workplace bills.
This law raises a legitimate and somewhat unsettling question for recruiters and HR professionals who built their contemporary workflows around algorithmic efficiency: Do your candidates and employees know how decisions are actually made about them? The truthful response has frequently been “no.” Illinois lawmakers most likely wanted to change that more than anything else in the law’s text.
