Fitness-for-Duty Exams: Your Rights When the Employer Requires a Medical Exam
Your employer says you need a fitness-for-duty examination before you can return to work — or before you can continue working. The exam is a medical evaluation, performed by a doctor the employer selects. Whether the employer can require it, what the doctor can ask, and what happens with the results are all governed by rules the employer may not be following.
A fitness-for-duty examination is a medical evaluation the employer requires to determine whether the employee can safely perform the essential functions of the job. Employers use fitness-for-duty exams when an employee returns from medical leave, when an employee exhibits behavior that raises safety concerns, or when the employer questions whether a medical condition affects the employee’s ability to work.
The exam is a legitimate tool — when used correctly. When used as a pretext to exclude a disabled employee, to gather medical information the employer is not entitled to, or to delay reinstatement after leave, the exam itself becomes a violation.
When the employer can require one
Under FEHA, an employer may require a fitness-for-duty examination only when the requirement is job-related and consistent with business necessity. This means the employer must have a reasonable, objective basis for believing that the employee’s medical condition may affect their ability to perform the essential functions of the job or may pose a direct threat to the employee or others.
After medical leave. An employer may require a fitness-for-duty exam when an employee returns from medical leave — but only if the employer requires the same exam of all similarly situated employees returning from leave for similar conditions. A policy that requires a fitness-for-duty exam only for employees returning from mental health leave, but not for employees returning from orthopedic surgery, is discriminatory.
Observable behavior. An employer may require an exam when the employee exhibits behavior that raises legitimate safety concerns — erratic behavior, signs of impairment, inability to perform physical tasks safely. The concern must be based on objective observation, not on stereotypes about the employee’s condition.
Not as fishing. An employer may not require a fitness-for-duty exam as a fishing expedition — to discover medical conditions the employee has not disclosed, to gather information to support a predetermined termination decision, or to delay the employee’s return from leave.
What the exam can and cannot cover
The examination must be limited to the specific question of whether the employee can perform the essential functions of the job. The examining physician should evaluate the employee’s functional capacity — their ability to perform the specific physical or cognitive tasks the job requires — not the employee’s complete medical history.
The employer should provide the examiner with a job description identifying the essential functions and the physical or cognitive demands. The examiner should evaluate the employee against those demands — and should report whether the employee can perform them, with or without accommodation.
The examiner should not disclose the diagnosis to the employer unless the employee consents. The employer is entitled to know whether the employee can perform the essential functions. It is not entitled to know the employee’s diagnosis, treatment plan, or medical history — beyond what is necessary to evaluate functional capacity and identify potential accommodations.
What happens with the results
The results of a fitness-for-duty examination are medical information subject to FEHA’s confidentiality requirements. The employer must keep the results separate from the employee’s general personnel file, must share them only with those who have a legitimate need to know, and must use them only for the purpose for which the exam was conducted.
If the examiner concludes the employee can perform the essential functions — with or without accommodation — the employer must reinstate the employee. If the examiner identifies restrictions, the employer must engage in the interactive process to determine whether reasonable accommodations exist.
If the examiner concludes the employee cannot perform the essential functions even with accommodation, the employer may take adverse action — but only after engaging in the interactive process and exploring all reasonable alternatives, including reassignment to a vacant position.
When the exam is misused
A fitness-for-duty exam is misused when it serves a purpose other than evaluating the employee’s ability to work.
Delay tactic. The employer requires the exam — then takes weeks to schedule it, weeks to receive the results, and weeks to evaluate the findings. The employee remains off work, unpaid, throughout. The delay is the purpose. The exam is the mechanism.
Pretextual basis for termination. The employer requires the exam expecting the employee to “fail” — and uses the results to justify a termination it had already decided upon. The exam provides a medical veneer for a decision that was actually motivated by the employee’s disability, leave, or complaint.
Discriminatory application. The employer requires the exam of one employee — the one with the known disability, the one who took medical leave, the one who filed a complaint — but does not require it of similarly situated employees who do not share the characteristic. The selective application is discrimination.
What employees should know
An employee who is required to undergo a fitness-for-duty examination should cooperate — but should also understand their rights. The exam must be job-related. The examiner should evaluate functional capacity, not conduct a general medical inquiry. The results must be kept confidential. And the exam should not be used to delay reinstatement or to manufacture a basis for termination.
If you believe the exam is being used as a pretext — to delay your return, to justify a predetermined decision, or to discriminate — document the timeline, note whether the exam is applied consistently, and consult with an attorney.
A fitness-for-duty examination is a legitimate tool when it is job-related, consistently applied, and used to evaluate your ability to perform the essential functions of your job. When it is used to delay reinstatement, to fish for medical information, or to justify a predetermined termination — the exam itself may be the violation.
