Parental Leave in Illinois: FMLA, Paid Leave, and Accommodations

Parental leave in Illinois comes from a stack of overlapping laws rather than a single program. If you work for a private employer with 50 or more employees nearby and you have been there at least a year, the federal Family and Medical Leave Act gives you up to 12 weeks of unpaid, job-protected time to bond with a new child. Nearly every Illinois worker also earns at least 40 hours of general paid leave each year that can be used for bonding, with separate rules in Chicago and the rest of Cook County. State government employees get a stronger benefit: 10 weeks of fully paid parental leave. What you actually qualify for depends on your employer’s size, your tenure, and where in the state you work.

FMLA: 12 Weeks of Unpaid, Job-Protected Leave

The Family and Medical Leave Act is the backbone of parental leave for most Illinois workers. It gives you up to 12 workweeks of unpaid leave in a 12-month period for the birth of a child or the placement of a child through adoption or foster care.¹ The pay is on you, but your job is protected and your employer must keep your group health insurance active on the same terms as if you were still working.²

You qualify only if all three of these are true:

Your employer has at least 50 employees within 75 miles of your worksite.
You have worked for that employer for at least 12 months.
You have logged at least 1,250 hours of actual work in the 12 months before your leave starts.

Miss any one of those and the FMLA does not cover you.¹ Paid time where you did not actually work generally does not count toward the 1,250 hours.

When your leave ends, your employer must put you back in your old position or in one that is virtually identical in pay, benefits, and working conditions.¹

Two FMLA Rules New Parents Miss

Bonding leave expires 12 months after the birth or placement date. Any portion of the 12 weeks you have not used by then is gone.³ If you want to split the time into blocks across the first year, start the clock early enough to use it all.

Intermittent bonding leave is not automatic either. Unlike FMLA leave for a serious health condition, which you can take in partial-day or partial-week chunks, bonding leave can only be broken up if your employer agrees.⁴ Without that agreement, the 12 weeks come in one continuous stretch.

And although your employer keeps your health plan active, you are still responsible for your usual share of the premium during unpaid leave. Stop paying and your coverage can be dropped.

State Paid Leave You Can Use for Bonding

Since January 1, 2024, nearly every private-sector worker in Illinois accrues paid leave under the Paid Leave for All Workers Act. You earn one hour for every 40 hours worked, up to a minimum of 40 hours in a 12-month period.⁵ That bank can be used for any reason, bonding with a newborn or newly placed child included. You do not have to tell your employer why, and your employer cannot require a doctor’s note or demand that you find your own shift coverage.⁶

The time is paid at your regular hourly rate. Part-time workers accrue on the same formula, so a 20-hour-a-week schedule still builds a bank. Some employers frontload the full 40 hours at the start of the year instead of tracking accrual.⁵

Two groups are not covered. Workers under a collective bargaining agreement that was in effect on January 1, 2024, are excluded. And employees of employers already subject to a local paid leave ordinance that existed on that date are governed by the local rules instead.⁶

If You Work in Chicago or Suburban Cook County

Chicago workers are covered by the city’s Paid Leave and Paid Sick Leave Ordinance rather than the statewide Act. You earn one hour of paid leave and one separate hour of paid sick leave for every 35 hours worked, giving you two distinct banks. The paid leave bank works like the statewide version and can be used for bonding. You qualify after working at least 80 hours for a Chicago employer within any 120-day period.⁷

Suburban Cook County employees fall under the Cook County Paid Leave Ordinance, which uses the same one-hour-per-40-hours accrual as the state law but requires employers to let you carry over at least 40 hours of unused paid leave into the next accrual period.⁸ You count as a Cook County employee if at least 50 percent of your compensated work happens inside the county.

10 Weeks Paid for State of Illinois Employees

If your employer is the State of Illinois itself, you are entitled to 10 weeks of fully paid parental leave for the birth of a child or a new adoption.⁹ When both parents work for the state, each is individually entitled to the full 10 weeks and can take them concurrently or back to back.

The leave is used in week-long increments of five consecutive working days. For a birth, you provide proof of pregnancy at least 30 days before the due date, then proof of the birth and the parent-child relationship. For adoption, the 10 weeks begin when you take physical custody (with the adoption process underway) or when you file the adoption petition for a child already in your foster care. If the child has been in your foster care for more than three years, the adoption leave benefit does not apply.⁹

This paid benefit runs alongside your FMLA entitlement rather than on top of it. You get a paycheck for 10 of the 12 FMLA weeks instead of taking all 12 unpaid.

Pregnancy Accommodations Before Leave Starts

Before you ever file a leave request, both federal and Illinois law require your employer to accommodate pregnancy-related physical limitations so you can keep working. The federal Pregnant Workers Fairness Act, effective June 2023, applies to employers with 15 or more employees and requires reasonable accommodations for known limitations tied to pregnancy, childbirth, or related medical conditions.¹⁰ Your employer cannot push you onto leave if another accommodation would let you keep working.

Common accommodations the EEOC lists include more frequent breaks, access to water and food, a stool for seated work, a modified or shorter schedule, temporary reassignment to lighter duties, and telework.¹¹

The Illinois Human Rights Act separately bars employment discrimination based on pregnancy, childbirth, or related conditions, with protection extending to past pregnancy, intended pregnancy, fertility treatment, and related conditions.¹² If your employer refuses a reasonable accommodation, you can file a charge with the Illinois Department of Human Rights.

Leave After a Pregnancy Loss or Failed Placement

Illinois’s Family Bereavement Leave Act covers the situations the parental leave laws do not. It provides up to 10 workdays of unpaid leave following a miscarriage, stillbirth, unsuccessful reproductive procedure, failed adoption match, failed surrogacy agreement, or a diagnosis that negatively affects your pregnancy or fertility.¹³

Eligibility matches the FMLA: 12 months of employment, 1,250 hours worked, and an employer with 50 or more employees within 75 miles. The leave is unpaid and runs concurrently with any FMLA entitlement.

How to Request Leave and Protect It

For foreseeable FMLA leave, like a due date or scheduled placement, give your employer at least 30 days of advance notice. If circumstances change and that is not possible, notify your employer as soon as practical.¹⁴ Notice for paid leave under the statewide Act follows whatever your employer’s written policy says.

Once you submit an FMLA request, your employer has five business days to give you a written eligibility notice.¹⁵ If the employer asks for medical certification, you have 15 calendar days to provide it, with extensions available if getting the paperwork is genuinely not practicable despite a good-faith effort.¹⁶

For a birth, medical certification from your healthcare provider confirming the pregnancy or delivery date is enough. For adoption or foster placement, gather your placement documentation or court papers. State employees requesting paid parental leave should go through their agency’s personnel office, since the administrative code lays out separate documentation requirements.⁹

Retaliation Is Illegal: What to Do If It Happens

Under the Paid Leave for All Workers Act, your employer cannot take adverse action against you for using leave, oppose your attempts to use it, or count paid leave usage as a negative factor in performance reviews, discipline, or attendance policies. You can file a claim with the Illinois Department of Labor for relief.¹⁷

Under the FMLA, interfering with your right to take leave, denying a valid request, or retaliating for leave you already took all violate federal law. The Wage and Hour Division investigates complaints, and you can also file a private lawsuit, generally within two years of the violation.¹⁸ If you are fired, demoted, or have your schedule changed after taking parental leave, document the timeline and the specifics in writing, and act quickly.
