Overview of Hiring Laws in Illinois

Illinois upholds a comprehensive set of employment and hiring laws designed to protect workers’ rights and promote fair labor practices. These laws are enforced primarily by the Illinois Department of Labor (IDOL), ensuring employers follow state and federal standards related to wages, discrimination, workplace postings, and employment verification.

Illinois offers broader protections than federal laws in several areas, particularly in equal pay, rest periods for minors, and wage transparency. Employers operating in Illinois must comply with both state and federal employment regulations.

Illinois continues to strengthen its labor standards through new regulations promoting equal opportunity, fair compensation, and accountability in employment practices.

Illinois Hiring Laws

Anti-Discrimination and Equal Opportunity Laws

Illinois strictly prohibits discrimination in hiring and employment under the Illinois Human Rights Act (IHRA). Employers cannot discriminate based on:

• Race, colour, national origin, or ancestry
  
• Religion or creed
  
• Sex, gender identity, or sexual orientation
  
• Pregnancy or childbirth-related conditions
  
• Age (40 and above)
  
• Marital or military status
  
• Physical or mental disability

Employers are required to post the “Your Rights Under Illinois Employment Laws” notice and provide reasonable accommodations to qualified applicants with disabilities or pregnancy-related conditions.

Pay Equity and Wage Transparency

Illinois enforces one of the nation’s strongest pay equity laws through the Equal Pay Act of 2003, amended in 2025 to include pay transparency requirements.

• Employers with 15 or more employees must include pay scales and benefits in all job postings.
  
• Companies with 100 or more employees must file Equal Pay Registration Certificates (EPRCs) every two years.
  
• Employees performing “substantially similar work” must receive equal pay regardless of gender or race.

Example: If two marketing coordinators perform similar duties but receive different pay, the employer must justify the disparity based on factors such as experience, education, or performance, rather than gender or race.

Background Checks and Criminal History Rules

Illinois follows a “ban-the-box” policy under the Job Opportunities for Qualified Applicants Act. Employers cannot inquire about an applicant’s criminal history until a conditional offer has been extended.

If a background check reveals a conviction, the employer must conduct an individualized assessment, considering:

• The nature and severity of the offence
  
• Time elapsed since the conviction
  
• The relationship between the offence and the job duties

Applicants have the right to respond and provide mitigating information before a final decision is made.

I-9 and Employment Eligibility Requirements

Illinois employers must complete the federal Form I-9 for all new hires to verify identity and employment eligibility. While federal law allows the use of E-Verify, Illinois limits its mandatory use to specific industries or federal contractors.

Employers are prohibited from using E-Verify to pre-screen applicants or reverify employees unnecessarily. All I-9 forms must be stored securely and available for inspection upon request.

State-Specific Hiring Rules

Illinois has additional employment rules that go beyond federal requirements:

Penalties for Non-Compliance in Illinois

Illinois imposes strict penalties for violations of hiring and labor laws.

• Fines and Penalties: Employers may face fines ranging from $500 to $5,000 per violation, depending on the severity of the infraction.
  
• Employee Lawsuits: Workers may file claims for back pay, damages, and attorney fees under the Illinois Human Rights Act or Equal Pay Act.
  
• Administrative Sanctions: IDOL may order wage restitution, suspend licenses, or revoke business permits for repeated violations.

Example: In 2024, an Illinois restaurant was fined $20,000 and required to issue back pay after violating ODRISA meal break provisions for kitchen staff.

Notice and Documentation HRs Need to Know

To remain compliant, HR professionals in Illinois should maintain and update the following:

• Signed Acknowledgment of Wage and Hour Policies- Employers must distribute written wage-and-hour policies that explain pay schedules, meal breaks, and rest periods. Employees should acknowledge receipt in writing.
• Completed Form I-9s for All New Hires- Every new hire must complete Form I-9 within three business days of employment. Employers must retain these records for three years after the employee’s hire date or one year after the employee’s termination date.
• Pay Scale Documentation for Job Postings- From 2025, job postings must include pay range and benefits. HR teams should store this documentation for at least three years to demonstrate compliance with pay transparency laws.
• Training Records on Harassment Prevention- Employers must provide annual sexual harassment prevention training and keep proof of completion for all employees and supervisors.
• New Hire Reporting to IDES- All new hires and rehires must be reported to the Illinois Department of Employment Security within 20 days, including employees’ SSNs and employers’ FEINs.
• Workplace Posters and Notices- Employers must display up-to-date versions of the required posters, including those on minimum wage, equal pay, and employment rights. These can be downloaded from the Illinois Department of Labor website.
