Parents working in Illinois can take up to 12 weeks of unpaid, job-protected leave under the federal Family and Medical Leave Act, and separately earn at least 40 hours of paid leave each year under the state’s Paid Leave for All Workers Act. Chicago workers get more. Illinois parental leave laws do not include a state-funded paid family leave insurance program, so most of your leave is unpaid unless your employer offers a parental benefit or you stack accrued time on top. The practical picture for most families is a layered one: federal unpaid weeks, a small bank of state-mandated paid hours, whatever the employer adds, and, in Chicago, a second paid bank from the city ordinance.
The 12 Weeks of Federal FMLA Leave
The FMLA gives eligible employees up to 12 workweeks of unpaid leave in a 12-month period for the birth of a child, the placement of a child for adoption or foster care, and bonding with that child.1U.S. Department of Labor. Fact Sheet 28Q – Taking Leave from Work for Birth, Placement, and Bonding with a Child under the FMLA Bonding leave must be used within 12 months of the birth or placement. You can take it in one continuous stretch or, only with your employer’s agreement, in intermittent blocks.
Three eligibility rules have to line up:
- You have worked for your employer for at least 12 months.
- You have logged at least 1,250 hours in the 12 months before leave begins.
- Your employer has at least 50 employees within 75 miles of your worksite.2U.S. Department of Labor. Family and Medical Leave
Miss any one of these and FMLA does not apply, which is a common gap for people at small businesses or in their first year on a job.
Coming Back to Your Job
When your leave ends, your employer has to put you in the same position or one that is virtually identical in pay, benefits, duties, and worksite. Any across-the-board raise that happened while you were out, such as a cost-of-living adjustment, applies to your returning pay, and your benefits resume without any requirement that you re-qualify.3U.S. Department of Labor. Family and Medical Leave Act Advisor – Equivalent Position
A narrow exception exists for “key employees,” meaning salaried workers in the highest-paid 10 percent of the workforce within 75 miles. An employer can refuse to restore a key employee’s job if reinstatement would cause substantial and grievous economic injury, but must warn you of that status when you request the leave rather than after.4U.S. Department of Labor. Family and Medical Leave Act Advisor – Key Employees The right to take the leave and keep health insurance stays intact either way.
If Both Parents Work at the Same Company
Two spouses employed by the same company share a combined 12 weeks of FMLA bonding leave, not 12 weeks each.5U.S. Department of Labor. Fact Sheet 28L – Leave under the FMLA When You and Your Spouse Work for the Same Employer Medical recovery from childbirth is separate, though. The birthing parent’s own recovery counts as a serious health condition, and each spouse also keeps a full individual 12 weeks for any serious health condition of their own.
Health Insurance While You Are Out
Your group health coverage continues on the same terms during FMLA leave. Family coverage stays family coverage. If premiums or plan terms change for everyone at the company while you are out, those changes apply to you, but your employer cannot single you out for higher costs.6U.S. Department of Labor. Fact Sheet 28A – Employee Protections under the Family and Medical Leave Act
Because the leave is unpaid, you still owe your share of the premium. Your employer must send advance written notice explaining how and when to pay, whether on your normal paycheck cycle, a COBRA-style schedule, or another arrangement you agree to.7U.S. Department of Labor. Family and Medical Leave Act Advisor – Employee Payment of Group Health Benefit Premiums Missed premium payments can put your coverage at risk, so plan for it before leave begins.
Paid Leave Under Illinois Law
Since January 1, 2024, nearly every worker in Illinois earns paid leave under the Paid Leave for All Workers Act. You accrue one hour of paid leave for every 40 hours worked, up to at least 40 hours per year, and you can use it for any reason at all — bonding, prenatal appointments, recovery, or something unrelated to the pregnancy.8Illinois General Assembly. Illinois Code 820 ILCS 192/15 – Paid Leave for All Workers Act The law bars employers from requiring a reason or supporting documentation.
Two timing rules matter. Accrual starts on your first day (or the law’s effective date, whichever came later), but you cannot actually use the hours until you have been on the job for 90 days. If the need is foreseeable, like a due date already on the calendar, your employer can require seven calendar days’ notice. For anything unforeseeable, notice is due as soon as practical.
Carryover, Frontloading, and Payout at Separation
Unused hours carry over year to year if your employer uses accrual. If your employer instead frontloads the full 40 hours at the start of the year, no carryover is required. When your employment ends, unused hours accrued specifically under this law do not have to be paid out. There is a big exception: if your employer folds this paid leave into a general vacation or PTO bank, then unused vacation time is still owed at separation under the Illinois Wage Payment and Collection Act.9Illinois Department of Labor. Paid Leave for All Workers Act FAQ How your employer structures the benefit decides what lands in your final paycheck.
Chicago’s Additional Paid Leave
Workers in Chicago get considerably more. Under Chapter 6-130 of the Municipal Code, employers must provide two separate banks: general paid leave and paid sick and safe leave. You accrue one hour of each for every 35 hours worked, building both banks at the same time, for a potential total of 80 paid hours per year.10Municipal Code of Chicago. Chicago Municipal Code 6-130-030 – Paid Sick Leave and Paid Leave
For a parent, that split is useful. The sick leave bank fits medical recovery and prenatal or postnatal appointments; the general paid leave bank fits bonding time. You qualify by working at least 80 hours for your employer within the geographic boundaries of Chicago during any 120-day period. Accrual under the ordinance began July 1, 2024, or your first day of employment, whichever came later.11City of Chicago. Paid Leave and Paid Sick Leave
Pregnancy and Nursing Rights at Work
Parental leave sits alongside a separate set of workplace protections that apply before you leave and after you come back.
Accommodations During Pregnancy
The federal Pregnant Workers Fairness Act requires employers with 15 or more employees to provide reasonable accommodations for limitations related to pregnancy, childbirth, or related medical conditions, unless doing so would impose an undue hardship.12Office of the Law Revision Counsel. United States Code Title 42 Chapter 21G – Pregnant Worker Fairness Typical accommodations include more frequent breaks, a modified schedule, temporary reassignment to lighter duties, telework, and adjustments to equipment or workstations.13U.S. Equal Employment Opportunity Commission. What You Should Know About the Pregnant Workers Fairness Act
Watch for one specific violation. The law prohibits an employer from forcing you onto leave, paid or unpaid, when a different reasonable accommodation would let you keep working. Being pushed out the door prematurely is itself a potential violation, not a favor.
Breaks for Nursing
The federal PUMP Act requires employers to provide reasonable break time and a clean, private space (not a bathroom) for expressing breast milk for up to one year after a child’s birth.14Office of the Law Revision Counsel. United States Code Title 29 Section 218d – Accommodations for Pregnant and Nursing Workers Illinois adds a meaningful upgrade under the Nursing Mothers in the Workplace Act (820 ILCS 260): the break time must be paid. Those breaks can run concurrently with your existing paid break schedule, and your employer must provide additional paid time if you need more.
Bridging the Gap Between Paid and Unpaid Time
Illinois does not run a paid family leave insurance program. That leaves a wide gap for most parents: 40 paid hours from the state act (or up to 80 in Chicago) against 12 weeks of unpaid FMLA. Everything in between depends on what your employer offers.
Some employers provide supplemental parental leave benefits or short-term disability coverage, and many let you stack accrued PTO on top of FMLA to keep a paycheck coming. Without those, the remaining weeks are simply unpaid. A private short-term disability policy purchased before pregnancy, and a savings buffer built during the pregnancy, are the practical tools for closing the gap.
Unpaid weeks also affect retirement contributions. Because 401(k) deferrals and employer matches come from payroll, both stop when the paycheck stops. Your account balance keeps moving with the market, but new contributions pause. Confirm with your plan administrator how the pause affects vesting before you leave.
Paid hours you do use under the state act or Chicago ordinance are treated as regular wages, with normal income, Social Security, and Medicare withholding.
Requesting Leave and What You Have To Show
The two systems have very different documentation rules, and it helps to understand them before you file anything.
For FMLA leave that is foreseeable — a due date, a scheduled adoption placement — you owe your employer at least 30 days’ advance notice.15U.S. Department of Labor. Fact Sheet 28E – Requesting Leave under the Family and Medical Leave Act You are not required to say the letters “FMLA.” Describing the situation is enough, and the employer bears responsibility for recognizing an FMLA-qualifying reason. For Illinois paid leave tied to a known date, seven calendar days’ notice is enough.
Within five business days of your request, your employer must send an eligibility notice confirming whether you meet the FMLA criteria and laying out your rights and duties during leave, including premium payment logistics.16eCFR. Title 29 CFR Section 825.300 – Employer Notice Requirements If it does not arrive, follow up in writing. Silence is not approval.
On documentation, FMLA and the state act pull in opposite directions. For the birthing parent’s medical recovery, employers often request a medical certification from a health care provider.17U.S. Department of Labor. FMLA Forms Adoption or foster placement is verified with placement papers or a court order. Bonding leave by a non-birthing parent needs no medical documentation, because you are not claiming a health condition. The Illinois Paid Leave for All Workers Act, by contrast, prohibits requiring a reason or supporting paperwork at all.8Illinois General Assembly. Illinois Code 820 ILCS 192/15 – Paid Leave for All Workers Act
Keep copies of everything: your request, any certification, the employer’s eligibility notice, and email correspondence. Employers can retroactively designate leave as FMLA-qualifying once they know the reason qualifies, but they cannot retroactively deny protection once they had enough information to make that call. Your records are what settle the question if it ever comes up.
