Pregnancy Accommodation Rights in Illinois: Employer Obligations

Federal law prohibits pregnancy discrimination under Title VII of the Civil Rights Act of 1964, 42 U.S.C. § 2000e, enforced by the Equal Employment Opportunity Commission (EEOC). Title VII covers employers with 15 or more employees. The law treats pregnancy-related conditions the same as other temporary medical conditions—if an employer provides accommodations to non-pregnant employees with temporary limitations, it must provide equivalent accommodations to pregnant employees.

In 2023, the Pregnant Workers Fairness Act (PWFA), codified at 42 U.S.C. § 2000gg, expanded federal protections. The PWFA applies to employers with 15 or more employees and requires reasonable accommodations for known limitations related to pregnancy, childbirth, or related medical conditions unless the accommodation causes undue hardship. Unlike Title VII, the PWFA does not require comparison to how the employer treats non-pregnant employees—it is a direct duty to accommodate.

Federal law permits accommodations such as temporary leave, schedule flexibility, modified job duties, seating allowances, telework, paid or unpaid leave, and additional breaks. The EEOC enforces both Title VII pregnancy discrimination claims and PWFA claims. Remedies include back pay, front pay, compensatory damages for emotional distress, punitive damages (up to $300,000 for large employers), and attorney fees. Employees can recover damages even if they were not terminated—being denied an accommodation or suffering harassment related to pregnancy is sufficient harm.

Illinois law strengthens federal pregnancy protections through the Illinois Pregnant Workers Fairness Act (PWFA), effective January 1, 2024, codified in the Illinois Human Rights Act at 775 ILCS 5/2-109. The state PWFA mirrors the federal PWFA but applies to all Illinois employers, including those with fewer than 15 employees. This is a significant expansion: the federal PWFA only covers employers with 15+ employees, but Illinois covers employers of all sizes, including sole proprietors.

Under Illinois law, employers must provide reasonable accommodations for known limitations related to pregnancy, childbirth, or related medical conditions. Accommodations include but are not limited to: more frequent breaks, modified work schedules, telework, modified duties, leave (paid or unpaid), seating, parking, or any other reasonable accommodation agreed upon by the employer and employee. The standard is identical to the federal rule—the employer must accommodate unless doing so causes undue hardship in terms of significant difficulty or expense relative to the employer's business.

Illinois covers more employers than federal law. A 10-person startup in Illinois must comply with the state PWFA, whereas federal Title VII and PWFA do not apply until 15 employees are reached. Additionally, Illinois law is enforceable through the Illinois Department of Human Rights (IDHR) and provides state remedies including attorney fees, emotional distress damages, and civil penalties. Illinois courts have also recognized implicit protections against harassment based on pregnancy status and family caregiver responsibilities.

The state does not recognize fetal injury as a separate claim (employers cannot deny accommodation based on fetal risk alone), and employers cannot require medical certification as a condition of providing accommodation—only reasonable verification that the limitation exists. Illinois law also protects employees who are breastfeeding or expressing milk, requiring employers to provide reasonable break time and a private space other than a bathroom.

Employers are not required to provide accommodations if doing so causes undue hardship—meaning significant difficulty or substantial increased cost relative to the size and resources of the employer. Very small employers (1-2 employees) may assert an undue hardship defense, though Illinois courts apply this narrowly. A sole proprietor cannot, as a matter of law, claim that one accommodation is an undue hardship simply because it is inconvenient; courts balance the magnitude of the burden against the employer's resources.

Employers are not required to provide accommodations that fundamentally alter the essential job functions or the nature of the business. For example, an employer cannot be required to eliminate a core job duty entirely. However, temporary modifications or lateral assignment is usually required. Employers may refuse an accommodation if the employee's medical provider (whom the employer can require to certify) states that the accommodation is contraindicated—that is, medically inadvisable for the employee's specific condition.

Illinois law does not protect employees from discipline for conduct unrelated to pregnancy accommodation requests. An employer can still terminate a pregnant employee for legitimate, non-discriminatory reasons (poor performance, policy violations, etc.), but the burden of proof is on the employer. Any employer action adverse to the employee is presumed retaliatory if taken within 90 days of the accommodation request, shifting the burden to the employer to prove legitimate, non-discriminatory reasons.

Union employees covered by collective bargaining agreements have the same rights, but the accommodation process may be adjusted through grievance procedures. Employees who are not actually pregnant but are perceived to be pregnant, or who have a history of pregnancy-related limitations, are protected. Employees who are denied accommodations but continue to work are not required to resign to pursue a claim—continuing to work does not waive the right to damages.

Step 1: Document Everything. Keep detailed records starting immediately after you discover you are pregnant or experience a pregnancy-related condition. Document the specific limitation (e.g., unable to stand for 8 hours, morning sickness, pelvic pain, gestational diabetes). Write down dates, times, and the impact on your ability to perform your job. Keep copies of any medical records, doctor's notes, or certification your employer requests. Save emails, text messages, or memos discussing your condition. Document any informal comments made by your supervisor about your pregnancy or work performance that may be pretextual. Take screenshots of scheduling changes, reassignments, or pay changes that occur after you disclose your pregnancy.

Step 2: Make a Formal Accommodation Request. Request the accommodation in writing (email is acceptable) to your HR department or direct supervisor. State that you are requesting a reasonable accommodation for a known limitation related to pregnancy under the Illinois Pregnant Workers Fairness Act and federal law. Be specific: describe the limitation, explain how it affects your work, and propose an accommodation (or ask your employer to suggest one). For example: "I am experiencing severe morning sickness and fatigue due to pregnancy. I request permission to adjust my start time from 8 a.m. to 10 a.m. to manage nausea, with adjusted lunch hours to maintain 8 hours per day." Keep a copy of this request. Do not wait for an illness—you can request accommodation as soon as you disclose pregnancy if you anticipate a need.

Step 3: Respond to Your Employer's Reply and Escalate if Necessary. Your employer must respond in a timely manner (best practice is within 5 business days, though the statute does not specify). If your employer grants the accommodation, confirm it in writing. If your employer denies the accommodation, ask for the reason in writing. If the reason is undue hardship, request documentation of the hardship. If your employer states it needs medical certification, provide it within 15 days; federal and Illinois law allow employers to request certification from your healthcare provider using a form like the DOL's guidance, but they cannot demand detailed medical records. If your employer still denies the accommodation after you provide certification, or if your employer retaliates (reduces pay, gives negative reviews, terminates, or reassigns you to worse duties within 90 days of your request), escalate internally to the next level of management or file a charge (see Step 3b).

Step 3b: File a Charge with the EEOC. File online at www.eeoc.gov or by mail with your local EEOC field office. Illinois has no state-dual-filing agency for PWFA claims as of 2024, so file directly with the EEOC. The deadline is 180 days from the date of the violation (the day the accommodation was denied or the retaliatory action occurred). The EEOC also accepts charges that are dual-filed with the Illinois Department of Human Rights (IDHR) under the state Pregnant Workers Fairness Act at www.cyberdriveillinois.com/departments/index/dhr. Include your name, address, employer name and address, date you started, date of the violation, description of the accommodation requested and denied, and any retaliation. Attach copies of your accommodation request email, your employer's denial, and medical records or certification. The EEOC will notify your employer that a charge was filed (this triggers the "look back" period—the employer may not retaliate after receiving notice, or it will strengthen your case).

Step 4: EEOC Investigation Process. After you file, the EEOC will mail you an intake questionnaire; complete it and return it within 5 business days. The EEOC then decides whether to investigate. If the EEOC investigates, it will request documents from your employer (your personnel file, scheduling records, accommodation correspondence, and the supervisor's notes). The investigation typically takes 60-180 days. The EEOC will notify you and your employer of its determination: "Reasonable Cause" (the charge has merit and the EEOC believes discrimination occurred) or "No Reasonable Cause." If the EEOC finds Reasonable Cause, it will offer mediation; both you and the employer must agree to mediate. Mediation is confidential and free. If mediation fails, the EEOC may issue a Right to Sue letter, which allows you to file a civil lawsuit in federal court. If the EEOC closes the case without finding Reasonable Cause, you still receive a Right to Sue letter after 180 days if you request one.

Step 5: Consult an Attorney. Contact an employment law attorney as soon as possible after your employer denies the accommodation, especially if retaliation occurs. An attorney specializing in pregnancy discrimination can evaluate whether your case is strong, estimate damages, and handle the EEOC charge and litigation. Many employment lawyers work on contingency (no upfront fee; they take a percentage of any recovery). In Illinois, prevailing employees recover attorney fees from the employer, making contingency representation common. Do not sign any settlement or waiver without an attorney reviewing it. If your employer offers a settlement before or during EEOC investigation, an attorney ensures you receive fair value and that the settlement terms do not waive your right to future claims.
