IL HB3773

Adds definitions for "Artificial Intelligence" and "Generative Artificial Intelligence" to the Illinois Human Rights Act, defining AI as machine-based systems that infer from inputs to generate predictions, content, recommendations, or decisions that influence physical or virtual environments.

Prohibits employers from using artificial intelligence in recruitment, hiring, promotion, training, apprenticeship, discharge, discipline, tenure, or employment terms that subjects employees to discrimination based on protected classes or uses zip codes as a proxy for protected classes.

Requires employers to provide notice to employees when using artificial intelligence for employment decisions as described above, with the Department of Human Rights authorized to adopt rules on notice circumstances, timing, and delivery methods.

Expands the definition of "Employee" to include unpaid interns under certain conditions for purposes of harassment protections, requiring interns to receive educational benefits, not displace regular employees, and not provide immediate advantage to the employer.

Adds a new "Harassment" definition covering unwelcome conduct based on protected characteristics including race, color, religion, national origin, disability, sexual orientation, pregnancy, citizenship status, and work authorization status that substantially interferes with work performance or creates a hostile work environment.
