Quick Answer

Understand FMLA rights in Illinois. Learn about eligibility, covered reasons, job protections, and how Illinois leave laws supplement federal FMLA.

Quick Answer: The federal Family and Medical Leave Act (FMLA) provides eligible Illinois employees up to 12 weeks of unpaid, job-protected leave for serious health conditions, childbirth, adoption, or family care.
