IL HB4980

Prohibits Illinois public employers, including contractors and subcontractors, from using automated decision-making systems (AI, algorithms, computational models) without meaningful and continuing human review when functions affect employee rights, safety, welfare, or public assistance programs

Requires initial impact assessments 30 days before implementing any automated decision-making system, with additional assessments every 2 years or before material changes, signed by both a responsible human reviewer and an independent auditor

Bans specific AI uses including predicting employee behavior/personality/emotional states, facial/gait/emotion recognition technologies, wage deductions for exercising legal rights, and AI-based hiring, performance evaluation, promotion, or termination decisions

Mandates that AI system implementation cannot result in employee displacement, reduced hours or wages, or transfer of employee duties to automated systems without prior union notification and negotiations

Establishes enforcement through the Department of Labor and provides private rights of action for employees, with anti-retaliation protections for those who report violations
