Illinois: New Job-Protected NICU Leave Effective June 1, 2026

Illinois enacted the Family Neonatal Intensive Care Leave Act via House Bill 2978. The law creates a new category of job-protected, unpaid leave for employees whose child is a patient in a neonatal intensive care unit (NICU). The requirements apply to employers with 16 or more employees and take effect June 1, 2026.


Summary of key changes:

  • Tiered unpaid NICU leave by employer size
    Employers with 16–50 employees must provide up to 10 days of unpaid NICU leave; employers with 51+ employees must provide up to 20 days. Leave is capped at the applicable maximum or the length of the child’s NICU stay, whichever is less. 
  • Intermittent use permitted
    Leave may be taken continuously or intermittently at the employee’s selection; employers may require minimum increments of not less than two hours. 
  • Coordination with FMLA and paid leave
    Employees eligible for FMLA must access NICU leave after completing FMLA leave taken (NICU leave is in addition to FMLA). Employers cannot require substitution of paid leave, though employees may elect to substitute other available paid or unpaid leave.

Employer action steps:

  • Confirm coverage & employee counts to determine whether the 16-employee threshold (and the 16–50 vs. 51+ tier) applies.
  • Update policies, handbooks, and templates to add NICU leave, reflect FMLA sequencing, and document intermittent leave increments and verification practices. 
  • Train HR and supervisors on eligibility triggers, reinstatement/benefit continuation obligations, and acceptable verification (length-of-stay only; no HIPAA-protected information).
