Workers' comp, the ADA and FMLA: how they overlap

A single on-the-job injury can start three separate legal tracks: a workers' compensation claim under state law, job-protected leave under the federal Family and Medical Leave Act (FMLA), and a duty to consider reasonable accommodation under the Americans with Disabilities Act (ADA). They run at the same time, they have different coverage thresholds, and satisfying one does not satisfy the others. State law adds a fourth layer, because many states have their own leave and disability-discrimination statutes that go further than federal law.

The three laws side by side

The FMLA and ADA thresholds above are federal; confirm the FMLA details in the DOL's FMLA materials. Comp coverage rules differ by state; start with workers' comp requirements by state: who must carry it and the workers' comp and benefits requirements by state.

FMLA and workers' comp

A work injury that involves a serious health condition (inpatient care or continuing treatment by a provider) can be FMLA-qualifying. DOL guidance says workers' compensation absence may run concurrently with FMLA leave when the reason qualifies as a serious health condition (Fact Sheet 28P). The practical rules:

• Designate it. When you know that a comp absence qualifies, you must notify the employee that the leave is being counted as FMLA leave. If you do not, the time may not count against the 12 weeks. DOL's model notice lists workers' compensation among the reasons that can be designated.
• Not every comp absence qualifies. If the employee misses only a day or two with no continuing treatment, there may be no FMLA leave.
• Paid leave substitution is limited. DOL's 2002 opinion letter says that an employee receiving workers' compensation payments cannot be required to, and does not have the option to, substitute accrued paid leave for that period. Check current guidance with counsel.
• Light duty. An employee cannot be compelled to take light duty in place of FMLA leave (29 CFR 825.702(d)); a voluntarily accepted assignment does not use up leave time. See light duty and transitional work: how to set it up.
• Reinstatement. At the end of FMLA leave, an employee is generally entitled to the same or an equivalent job. That right ends when the 12 weeks do, but the comp absence and ADA duties may continue.
• Health benefits. During FMLA leave you must maintain group health coverage on the same terms, whether or not the employee also receives comp benefits.

ADA and workers' comp

The EEOC's Enforcement Guidance: Workers' Compensation and the ADA (September 3, 1996) is still the agency's basic statement. Its central points:

• A work injury is not automatically an ADA disability. A person with an occupational injury is covered only if the impairment substantially limits a major life activity, or there is a record of or regarding as such an impairment. The ADA Amendments Act of 2008 made that test easier to meet, so the guidance's analysis should be read in light of the amendments.
• A comp claim does not defeat an ADA claim, and the reverse. Receiving comp benefits does not decide whether the person is qualified.
• Disability-related inquiries are limited. Before a job offer, you generally cannot ask about prior comp claims. After an injury, you may ask questions and require exams that are job-related and consistent with business necessity, such as asking the treating physician about restrictions that bear on the person's ability to do the job. Medical information goes in a separate confidential file.
• Reasonable accommodation can mean more than restrictions. It can include modified schedules, equipment, reassignment to a vacant position and unpaid leave, unless it would cause undue hardship.
• "100% healed" policies are risky. A rule that nobody returns until fully recovered fails to consider individual accommodation.
• Direct threat decisions must rest on an individualized, objective assessment of the person's present ability, not on fear of higher comp costs. The guidance specifically says concern about future workers' comp costs does not justify excluding a disabled applicant.
• Light duty. You need not create light-duty jobs for disabled employees who were not injured on the job, but reserved vacant positions for injured workers must be considered for reassignment of others.

The EEOC's 2016 resource on employer-provided leave and the ADA adds that an employer may provide leave under its comp program, the FMLA or another leave program when a request can be addressed that way, and that leave can be a reasonable accommodation once other leave is exhausted.

Putting it together: a sequence

1. Day of injury: report to the carrier and to OSHA if required (reporting a workplace injury: what employers must do).
2. Within days: HR checks FMLA eligibility and sends the eligibility and rights notice; the comp absence is designated as FMLA leave if it qualifies.
3. During leave: the carrier manages medical care and benefits. State temporary disability or paid family leave programs may also apply in a few states (state disability and paid family leave programs: every mandate in 2026).
4. As restrictions emerge: the return-to-work coordinator offers transitional work (return-to-work programs: how to build one).
5. If leave runs out and restrictions remain: begin the ADA interactive process: ask what the person needs, consider leave, schedule changes or a vacant position, and document the conversation.
6. At maximum medical improvement: if permanent restrictions remain, accommodation decisions become longer-term while the comp claim moves to permanent disability or settlement.

Where employers go wrong

• Firing at the end of 12 weeks without asking about further accommodation.
• Treating comp leave as automatically not FMLA, which can leave the employee's rights unprotected and expose the employer to claims.
• Disciplining an employee for work absence caused by the injury.
• Putting medical details in the personnel file or telling supervisors the diagnosis.
• Assuming the carrier's decision to accept the claim decides the ADA question.

Coverage for the lawsuits that result is usually under an employment practices liability policy, not workers' comp, so ask your broker how your EPLI treats ADA and FMLA claims.

Key takeaways

• One injury can trigger comp, FMLA and ADA duties at once, each with different thresholds (FMLA: 50 employees; ADA: 15; comp varies by state).
• Comp absence can run concurrently with FMLA leave if it is a serious health condition, but you must designate it.
• The EEOC's 1996 workers' comp guidance warns against "100% healed" rules and decisions driven by comp-cost fears; read it with the 2008 ADA amendments.
• Many states add leave and disability laws on top, so use the workers' comp and benefits requirements by state and consult counsel on specifics.
• Keep medical information confidential and document every accommodation conversation.
