Guidance from an HR consultant in Florida on what you can and can’t do when you suspect an employee is faking their medical leave.
As a small business owner, you might assume that if an employee is abusing their medical leave, you’re within your rights to go out and prove it.
That assumption can cost you millions.
Federal courts have made it clear that how you investigate matters just as much as what you find.
Get the process wrong, and you could be facing an ADA discrimination lawsuit or an FMLA retaliation claim instead of resolving the problem.
Here’s what you need to know before you take any action.
Start with a structured process, not surveillance
If you genuinely believe an employee is taking advantage of their medical leave, the first step should never be hiring a private investigator. It should be a fitness-for-duty evaluation or an independent medical exam.
An objective medical opinion tells you whether the employee’s reported limitations line up with their actual clinical condition. That alone can resolve your concern without any surveillance being necessary.
Beyond that, you should be doing two things consistently:
- Tracking absences in a structured way
- Using a formal return-to-work process
Both create a documented record. Both give you something concrete to point to if the situation escalates. And in many cases, they resolve the issue entirely.
If those steps have been taken and you still have a genuine basis to suspect fraud, seek HR consultancy services in Florida or legal advice before hiring an investigator. Skipping this step is where businesses create problems for themselves.
Surveillance is legal, but it’s not risk-free
Courts in the U.S. have confirmed that hiring a private investigator to watch an employee on medical leave is legal. That part is settled.
The risk comes from what happens after you collect the footage.
Employers who have successfully defended termination decisions based on surveillance share two common factors. They had specific, documented reasons to suspect abuse before they began watching. And they conducted a thorough investigation before making any employment decision.
One federal case illustrates this clearly. An employee was on FMLA leave for a shoulder injury. Surveillance captured him performing heavy construction work, including operating a concrete saw that exceeded his documented weight restriction. The employer took the time to research the equipment, confirm the violation, and build a solid record before acting. The court upheld the termination.
The employers who lose these cases take the opposite approach. They go straight from footage to firing without verifying whether the activity they captured actually conflicts with the employee’s medical condition.
Why a gut feeling will work against you
This is the area where small business owners most frequently get it wrong.
Seeing an employee on FMLA leave doing yard work or running errands doesn’t automatically mean they’re fit to return to their job. Chronic back pain, for example, might prevent someone from performing physically demanding duties at work while still allowing lighter everyday movement.
Courts recognize that distinction clearly.
Documented, specific grounds for suspicion are the minimum standard before you take any investigative action. A pattern of absences that looks suspicious, backed by records, is very different from a vague sense that something isn’t right.
Without that documentation, you’re building a case against your own business rather than against the employee.
The financial exposure is real
Medical leave and disability cases carry some of the highest risk for employers.
Conditions like chronic pain and autoimmune disorders are protected under the ADA, even when they’re invisible. An employee who appears perfectly healthy at the grocery store may still be unable to meet the physical demands of their role.
If you terminate someone whose absence is connected to a qualifying disability, and you’ve based that decision on surveillance footage without obtaining medical input, you’re exposed to both ADA discrimination and FMLA retaliation claims.
The financial consequences break down as follows:
- Compensatory and punitive damages under federal ADA law are capped based on company size. For employers with 15 to 100 employees, the cap is $50,000. For larger employers, it goes up to $300,000.
- Back pay and front pay have no cap.
- State disability laws may allow additional damages on top of federal limits.
For context, a 2024 jury awarded $1.675 million in a single ADA discrimination case. Of that, $1.5 million was in punitive damages alone.
These are not theoretical numbers. They’re real verdicts from real cases.
If you do gather surveillance evidence, don’t act on it immediately
One of the most important steps in this entire process is also the most overlooked.
If surveillance produces footage that appears to contradict an employee’s medical restrictions, get a medical professional to review it before you make any decisions. Have someone qualified assess whether what the footage shows actually conflicts with the employee’s documented condition.
That single step separates a defensible termination from a lawsuit.
You should also have a policy in your employee handbook that addresses the possibility of monitoring. If the evidence is ever challenged, having that policy in place puts you in a much stronger position.
A clear sequence to follow
If you suspect medical leave abuse, here is a sensible order of operations:
- Request a fitness-for-duty evaluation or independent medical exam.
- Track absences consistently and maintain a structured return-to-work process.
- If concerns remain after those steps, consult with an HR or legal professional before taking further action.
- If surveillance is conducted, have the footage reviewed by a medical professional before making any employment decision.
- Ensure your employee handbook includes a monitoring policy.
Each of these steps builds your paper trail and reduces your exposure. Skipping any of them increases your risk.
