A fitness-for-duty evaluation is one of the most useful tools HR has when an employee's health may be affecting safety or performance, and one of the easiest to get wrong. Order one without a solid reason and the employer has made an unlawful medical inquiry under the Americans with Disabilities Act (ADA). Skip one when the warning signs are obvious and the employer may be left explaining an injury it could have prevented.
This guide covers when the ADA allows an evaluation of a current employee, how it differs from the FMLA's return-to-work certification, what to send the evaluating provider, what HR may receive back, and what happens when the answer is "not fit."
A fitness-for-duty evaluation (also called a fitness-for-duty exam or fit-for-duty evaluation) is a medical or psychological assessment of whether a current employee can perform the essential functions of their job safely, with or without reasonable accommodation. The employer requests it, the employer chooses the scope, and the employer pays for it.
It is not the same thing as an FMLA fitness-for-duty certification, and HR teams that blur the two create problems.

Under the FMLA, an employer may require a certification that the employee can return to work after leave for their own serious health condition, but only under a uniformly applied policy for similarly situated employees, and only if the requirement was stated in the designation notice. If the employer wants the certification to address the employee's ability to perform essential functions, it must send a list of those functions with the designation notice. Our article on FMLA fitness-for-duty certification walks through those steps.
The FMLA rule itself recognizes the boundary. Under 29 CFR 825.312(h), once the employee is back at work, any medical examination at the employer's expense falls under the ADA and must be job-related and consistent with business necessity. The FMLA certification gets the employee in the door; any later evaluation has to stand on its own ADA justification.
The ADA regulation at 29 CFR 1630.14(c) allows an employer to require a medical examination or make an inquiry of a current employee only when it is job-related and consistent with business necessity. The EEOC's enforcement guidance on disability-related inquiries and medical examinations of employees explains what that means in practice: the employer generally needs a reasonable belief, based on objective evidence, that either:
Three words in that test do most of the work.
Objective. The belief must rest on facts the employer observed or reliably learned, not on rumor, a diagnosis the manager guessed at, or the fact that the employee mentioned a condition. "She seems off" is not enough. "She fell asleep twice operating the press this week, and her error rate tripled after she said she started a new medication" is.
Essential. The concern must be about essential functions, not marginal ones. An employee who cannot lift 50 pounds when lifting is a rare, reassignable task is not a candidate for an evaluation on that basis.
Limited. The EEOC guidance says inquiries must be limited in scope to what is needed. An evaluation triggered by a back injury does not justify a psychological workup or a full medical history.
The guidance also notes it was written in 2000, before the ADA Amendments Act broadened the definition of disability. The medical-inquiry rules, though, apply to every employee, disabled or not, which is why HR should apply them before worrying about whether a condition qualifies as a disability. Our overview of ADA limits on medical inquiries covers the broader rules for applicants and employees.
No list replaces judgment, but these fact patterns come up repeatedly.
An employee in a safety-sensitive role shows signs that a medical condition may be creating risk: a forklift operator with unexplained near-misses after a seizure at work, a nurse whose hand tremor is affecting medication administration, a driver who reports blackouts. The direct-threat standard is the anchor here. The question is a significant risk of substantial harm, assessed individually, not a generalized fear about the diagnosis.
Performance problems alone are a performance-management matter. They become a basis for an evaluation when there is objective evidence connecting them to a medical condition: the employee tells a supervisor that their medication makes them unable to concentrate, or a documented injury coincides with the decline. Without that link, handle it as performance.
When an employee returns from medical leave that is not FMLA-protected, or returns from FMLA leave and the employer later develops a new concern, the EEOC guidance allows inquiries or an exam when the employer has a reasonable belief that the employee's present ability to perform essential functions is impaired or that the employee poses a direct threat. The scope usually focuses on the condition that caused the leave.
The EEOC guidance allows periodic medical exams in limited circumstances, such as some public safety positions, if they are narrowly tailored to specific job-related concerns. Firefighter vision and cardiac screening is the classic example. Exams required by another federal law, such as Department of Transportation medical certification for commercial drivers, follow that law's rules.
Use a provider who understands occupational medicine and, for psychological concerns, a licensed psychologist or psychiatrist with fitness-for-duty experience. The EEOC guidance allows the employer to choose the provider when it is entitled to an evaluation, and the employer pays all costs associated with the visit.
The quality of the evaluation depends on what the provider receives. Send a referral packet that includes:
Tell the employee in writing what the evaluation is for, who will perform it, that the employer is paying, and that refusing to participate in a lawful evaluation may lead to discipline under your policy. Keep the tone factual.
HR needs answers to the job-related questions, not the employee's medical history. A good report says, in substance: fit for full duty; fit with these restrictions for this period; or not currently fit, with an expected reevaluation date. Ask the provider to put any detailed clinical findings in a separate section that stays with the provider unless needed.
Whatever you receive is confidential under 29 CFR 1630.14(c)(1). Information about a current employee's medical condition or history obtained through an exam or inquiry must be collected and maintained on separate forms and in separate medical files and treated as a confidential medical record. The regulation allows only narrow disclosures:
Section 1630.14(c)(2) adds that the information may not be used for any purpose inconsistent with the ADA rules. In practice: a locked or access-restricted medical file separate from the personnel file, a short list of people who can open it, and a supervisor briefing that sounds like "no lifting over 20 pounds through March 15," never "he has a herniated disc." The EEOC's workers' compensation guidance also allows sharing with a workers' comp carrier or state agency in accordance with state law when the condition is part of a claim.
A "not fit" result is the start of a process, not the end of one.
Start with accommodation. If the employee has a disability, ask whether a reasonable accommodation would let them perform the essential functions: modified equipment, schedule changes, temporary reassignment of marginal tasks, a vacant position they are qualified for. That conversation is the interactive process, and it should be documented the same way you would document any accommodation request.
Check leave rights. An employee who cannot work may be eligible for FMLA leave, state family or medical leave, paid sick leave, short-term disability, or workers' compensation if the condition is work-related. Leave can also be a reasonable accommodation under the ADA.
Use "not fit with restrictions" precisely. If the provider lists restrictions, compare them against the essential functions one by one. The EEOC's workers' compensation guidance warns against requiring an employee to be at "full duty" or fully recovered when they can perform essential functions with or without accommodation, unless the employer can show a direct threat.
Set a reevaluation date. Temporary conditions resolve. Put the next review on the calendar and tell the employee what will happen then.
Remember who decides. The provider gives a medical opinion. The employer, as the EEOC guidance puts it, bears the ultimate responsibility for deciding whether the employee can return. Document how you reached your decision.
A written policy is the best protection against an evaluation looking targeted. It should cover:
Then apply it the same way every time. Track each referral in a log: date, trigger, decision-maker, outcome. If two employees with similar facts were handled differently, the log should show why.
These decisions are where return-to-work programs succeed or stall. If your team handles them regularly, return-to-work training for HR is a practical way to get everyone using the same process.
Fitness-for-duty decisions touch the FMLA, the ADA, workers' compensation and confidentiality rules in a single file. The Return-to-Work Training & Certification program covers fitness-for-duty documentation, restoration rights, ADA reasonable accommodation, modified duty and coordination with leave administration in one self-paced online course, with an optional exam for the Certified Return-to-Work Administrator designation. Teams of three or more can enroll together and managers can track progress.
No. For current employees, the ADA allows a medical examination only when it is job-related and consistent with business necessity. The EEOC reads that to require a reasonable belief, based on objective evidence, that a medical condition will impair the employee's ability to perform essential functions or that the employee will pose a direct threat. A hunch, a disclosed diagnosis, or co-worker gossip does not meet that standard. The rule applies to all employees, not only those with disabilities, so treat every referral as needing a documented, job-related reason before it goes out.
When the employer requires an ADA fitness-for-duty evaluation, the employer pays. The EEOC guidance says that when an employer sends an employee to a provider of its choice, it must pay all costs associated with the visit. The FMLA return-to-work certification is different: under 29 CFR 825.312, the employee bears the cost of that certification and is not paid for the time or travel spent obtaining it. Check state wage-hour law on whether time spent at an employer-required exam must be paid.
Often, yes, and it can be a reasonable first step. Many employers ask the employee's own provider to answer the job-related questions first. If the documentation is insufficient, the EEOC guidance allows the employer to require an evaluation by a provider of its choice, after explaining what was missing and giving the employee a chance to provide it. For an FMLA return-to-work certification, the employee's own provider completes it and the employer cannot require a second or third opinion.
Only what the supervisor needs to manage the work. Under 29 CFR 1630.14(c)(1), supervisors and managers may be informed about necessary restrictions on work or duties and necessary accommodations. They should not be told the diagnosis, test results or medical history. The full report belongs in a separate, confidential medical file, not the personnel file. First aid and safety staff may be told when the condition might require emergency treatment.
If the evaluation is lawful, meaning it is job-related and consistent with business necessity, the employer can generally treat refusal like refusing any other legitimate work directive, following its written policy. Before acting, confirm the documented reason for the referral, that the employee received written notice of the purpose and logistics, and that the request was limited in scope. If the evaluation was not lawful in the first place, discipline for refusing it creates an ADA claim.
No. A return-to-work note or FMLA certification is usually a short statement from the employee's own provider that they can return, sometimes with restrictions. A fitness-for-duty evaluation is an employer-directed assessment, usually by a provider the employer chooses, answering specific questions about essential functions and safety. The note is routine at the end of leave; the evaluation needs a specific, objective justification.
