Illinois enacted the Family Neonatal Intensive Care Leave Act (Public Act 104‑0259), creating a new category of unpaid, job-protected leave for employees whose child is in a neonatal intensive care unit (NICU).
The law introduces a separate leave entitlement with broad eligibility and specific employer obligations, including job protection and benefits continuation.
This update applies to employers with 16 or more employees company-wide that have at least one employee primarily working in Illinois, and the law took effect on June 1, 2026.
What Employers Need to Do
- Confirm Illinois headcount and coverage to determine whether the employer must provide 10 or 20 days of NICU leave under the law.
- Update leave policies and handbooks to include NICU leave and clearly explain how it interacts with the Family and Medical Leave Act (FMLA) and any paid leave policies.
- Train HR, managers, and leave administrators on employee eligibility, sequencing NICU leave after FMLA where applicable, and the law’s anti-retaliation protections.
- Implement a consistent verification process that requests only limited confirmation of the NICU stay and duration, without seeking broader medical details.
- Align benefits and reinstatement procedures to ensure health coverage continues during leave and employees are restored to the same or an equivalent position afterward.
Overview
Illinois created a new, standalone leave law that provides unpaid, job-protected leave for NICU-related absences, introducing wider eligibility alongside strict employer requirements, especially around job protection and benefits continuation.
Coverage and Leave Entitlement
- Employers with 16–50 employees must provide up to 10 days of NICU leave, while those with 51 or more employees must provide up to 20 days.
- Leave is capped at the lesser of the statutory maximum or the length of the NICU stay.
- Employers with 15 or fewer employees are not covered by the law.
Broad Employee Eligibility
- Eligibility is not tied to tenure or hours worked, making it broader than the Family and Medical Leave Act (FMLA).
- Both full-time and part-time employees may qualify immediately.
- The law covers a broad definition of “child,” including non-traditional family relationships.
Leave Usage and Flexibility
- Employees may take leave continuously or intermittently, depending on their needs.
- Employers may require leave to be taken in minimum increments of at least two (2) hours.
- The law is designed to accommodate unpredictable NICU schedules and short-duration absences.
Interaction with FMLA and Paid Leave
- NICU leave is in addition to FMLA, and FMLA-eligible employees must use FMLA first.
- Employees may voluntarily substitute paid leave if they choose.
Employer Obligations and Protections
- Employers must reinstate employees to the same or a substantially equivalent position after leave.
- Employers must maintain health insurance coverage during the leave period.
- Employers are prohibited from retaliation or interference with NICU leave rights.
Why This Matters
This law matters because it creates a new, standalone leave obligation that operates alongside FMLA and applies to a broader group of employees, including new hires and part-time workers.
For employers, the key impact is operational: leave administration, eligibility determinations, and coordination with existing policies must be updated to account for overlapping but distinct leave entitlements.
Key Risks for Employers
- Misapplying FMLA-style eligibility rules and denying NICU leave to newly hired or part-time employees who may still qualify under the Illinois law.
- Forcing employees to use paid leave instead of unpaid NICU leave, even though the law prohibits requiring that substitution.
- Failing to properly sequence NICU leave after FMLA for employees who are eligible for both, creating compliance gaps in leave administration.
- Requesting overbroad medical documentation, which may increase legal exposure if the request goes beyond reasonable verification of the NICU stay.
- Inconsistent handling of leave requests, increasing the risk of retaliation or interference claims under the new law.
Additional Information
Employers may request reasonable verification of the NICU stay but should limit requests to confirming the fact and duration of hospitalization, avoiding broader medical inquiries.
Violations may result in enforcement by the Illinois Department of Labor, including civil penalties of up to $5,000 per affected employee, as well as potential complaints or civil actions.
IDOL can investigate and impose civil penalties up to $5,000 per violation (per affected employee), and employers may be ordered to pay unpaid wages and damages as appropriate. Courts can also award injunctive relief to enforce the Act. These provisions underscore the need for strict compliance to avoid liability.
