Practitioner steps for Illinois

  1. Step 1. Layer Illinois paid sick leave and any state PFL on top of federal FMLA and ADA — always run the interactive process for medical accommodations.
  2. Step 2. Track IL-specific pregnancy accommodation and lactation-break rules.
  3. Step 3. Use written accommodation determinations for every request; document essential functions and available alternatives.
  4. Step 4. Coordinate leave, ADA, and workers' compensation carefully — mishandled overlap is one of the most common Illinois employer claims.

Frequently asked (federal + Illinois overlay)

When does an employee become eligible for FMLA?

An employee is FMLA-eligible when they have worked for a covered employer for at least 12 months (not necessarily consecutive), for at least 1,250 hours in the 12 months before leave, and at a worksite with 50 or more employees within 75 miles.

Do FMLA and ADA cover the same leave?

They often overlap but are not the same. FMLA provides up to 12 weeks of unpaid, job-protected leave for qualifying reasons. The ADA can require additional leave as a reasonable accommodation after FMLA is exhausted, if it will enable the employee to return to work and does not cause undue hardship.

What is the ADA interactive process?

It is the good-faith dialogue between employer and employee to identify a reasonable accommodation that will allow the employee to perform the essential functions of the job. It should be documented, timely, and revisited if the situation changes.

What does the Pregnant Workers Fairness Act require?

The PWFA requires covered employers (15+ employees) to provide reasonable accommodations for known limitations related to pregnancy, childbirth, or related medical conditions, absent undue hardship — and prohibits requiring leave when another accommodation is available.
