FMLA Violations by Employees: Fraud, Missed Deadlines, Penalties

Employees commit FMLA violations by faking or altering medical paperwork, using leave for activities inconsistent with the certified condition, working elsewhere in ways that contradict a medical restriction, or missing the law’s notice and certification deadlines. Any of these can strip the leave of its protections. The regulation is blunt: an employee who fraudulently obtains FMLA leave is not protected by the Act’s job restoration or health benefits provisions.¹ In practice, that means termination with no viable retaliation claim.

Fraudulent Medical Certifications

Falsifying the paperwork is the clearest violation. Some employees alter the dates or severity on a healthcare provider’s certification. Others fabricate records outright. If a doctor authorizes three days of recovery and you change the form to say two weeks, that is fraud. Federal regulations spell out the result in two places: Section 825.312(g) strips fraud-based leave of protection, and Section 825.216(d) states identically that a fraudulent claim removes the right to job restoration and continued health benefits.²¹ There is no gray area when the paperwork itself is dishonest.

Claiming FMLA leave for a condition that doesn’t meet the statutory threshold is its own form of misuse. A “serious health condition” means an illness, injury, or physical or mental condition involving either inpatient care or continuing treatment by a health care provider.³ A common cold or a routine dental visit does not qualify.

Doing Things Your Certification Says You Cannot Do

Using leave for activities unrelated to the certified condition is a different type of abuse with the same consequences. The classic scenario is an employee who claims a debilitating back injury and is then spotted running a half-marathon or hauling furniture on a weekend move. The mismatch between what the medical paperwork says and what the employee is doing creates the problem.

Employers do not need to catch you in person. Social media has become one of the most common ways these cases unravel. Photos, check-ins, and tagged posts showing physical activity that contradicts a certified restriction can trigger an investigation. Employers are within their rights to review publicly available social media content when they have a documented reason to question the legitimacy of a leave claim. If your online activity directly contradicts the medical restriction your leave is based on, it serves as evidence of abuse.

Courts evaluate these terminations through what is known as the honest belief rule. If an employer conducts a reasonably informed investigation and honestly concludes the leave was abused, that belief is a legitimate reason for termination, even if the conclusion later turns out to be wrong. The employer does not need to prove fraud beyond a reasonable doubt. It needs a reasonable basis, grounded in specific facts, for believing the leave was misused. An employee who challenges the termination as retaliation carries the burden of proving the stated reason was a pretext for something unlawful.

Working a Second Job During Leave

Taking a second job while on FMLA leave is not automatically a violation, but it can become one quickly. If you claim a hand injury prevents you from doing your primary job but spend the leave doing manual labor for someone else, the credibility of your medical certification is gone. The core question is whether the outside work requires the same physical or mental capacities you said were impaired.

Even where the second job involves entirely different duties, many employers maintain uniformly applied moonlighting policies that restrict outside employment regardless of leave status. FMLA does not excuse you from following those policies. If a no-moonlighting rule applies to everyone and the employer enforces it consistently, violating it during FMLA leave can be treated the same as violating it any other time.

Missed Notice Deadlines

The FMLA imposes specific notice deadlines, and failing to meet them without a good reason can delay or eliminate your leave protections.

Foreseeable Leave

When you know in advance that you will need time off, such as a scheduled surgery, a planned birth, or a chemotherapy regimen, you must give your employer at least 30 days’ notice before leave begins.⁴ You are also expected to make a reasonable effort to schedule planned medical treatments at times that minimize disruption to the employer’s operations.⁵

Unforeseeable Leave

When the need for leave is unexpected, you must provide notice as soon as practicable. In practice, that usually means following your employer’s standard call-in procedures the same day or the next business day. If your company requires employees to call a specific number or contact a particular person when they will be absent, you need to follow that procedure even for FMLA leave. The only exception is when unusual circumstances genuinely prevent compliance, such as being incapacitated in an emergency room with no ability to make a phone call.⁶

If you skip the required notice and cannot justify the failure, your employer can delay or deny FMLA protection for the absence.⁴ That converts what would have been protected leave into an unexcused absence subject to whatever discipline the employer normally applies.

Intermittent Absences

Intermittent leave is where abuse allegations come up most often. An employee who reliably calls in sick every Friday or the Monday after a holiday weekend will draw scrutiny. Pattern-based absences are not automatically fraudulent, since some conditions genuinely flare on irregular schedules, but they do give employers grounds to request recertification or investigate. You still need to follow your employer’s standard call-in procedures each time you take an intermittent day.⁶

Missed Certification Deadlines

Once your employer requests a medical certification, you have 15 calendar days to deliver the completed paperwork.⁷ For foreseeable leave, the employer can deny FMLA coverage for the entire period between the deadline and whenever the certification finally arrives. For unforeseeable leave, the same denial applies unless extenuating circumstances made it genuinely impossible to meet the 15-day window. If you never produce the certification at all, the leave is simply not FMLA leave.⁸

One protection works in the employee’s favor. If your certification is incomplete or deficient but not fraudulent, the employer cannot immediately deny your leave. The employer must tell you in writing what information is missing and give you at least seven calendar days to fix it.⁹ This cure period disappears when the problem is fraud rather than incompleteness.

Your employer can also request recertification, generally no more than once every 30 days and only in connection with an actual absence. Recertification can be requested sooner if you ask for more leave than originally certified, if circumstances change significantly, or if the employer receives information casting doubt on your reason for being out.¹⁰ Failing to provide recertification within a reasonable time lets your employer deny continued FMLA protection.

What Happens If You Violate the FMLA

The biggest consequence is losing the right to reinstatement. An employee who fraudulently obtains FMLA leave is not protected by the Act’s job restoration or health benefits provisions.¹ In practice, that means termination without a viable retaliation claim.

Even without outright fraud, the regulations establish that you have no greater right to reinstatement than if you had been working the entire time. If the employer can show you would have been let go regardless of the leave, such as because of a layoff, a plant closing, or misconduct discovered during your absence, you have no right to come back.¹

Losing Health Coverage Protection

During FMLA leave, your employer must maintain your group health coverage on the same terms as if you were still working.¹¹ Fraud terminates that protection along with reinstatement rights.¹

Premium Clawback If You Do Not Return

Separately, if you do not come back after your leave runs out, the employer can recover its share of the health premiums it paid during your absence.¹² Depending on how long you were out and the cost of your plan, that can add up to thousands of dollars.

Two exceptions protect employees from the clawback. The employer cannot recover premiums if you fail to return because of the continuation or onset of a serious health condition that would otherwise entitle you to FMLA leave, or because of circumstances beyond your control, such as a spouse being unexpectedly transferred more than 75 miles away or being laid off while on leave.¹² Deciding not to return for personal preference does not qualify.
