Do I Have to Use FMLA While on Workers' Comp?

One of the most common questions injured workers ask is, “Do I have to use FMLA while I’m on workers’ comp?”

A workplace injury can affect every part of your life at once and turn it upside down. Suddenly, you’re trying to recover from your injury, keep up with medical appointments, and deal with lost income all while juggling what comes next with your job and your workers’ compensation claim. If HR is pushing FMLA, the situation can feel even more confusing. That’s why so many injured employees ask the same question: Do I have to use FMLA while on workers’ comp?

You do NOT have to use FMLA to receive workers’ compensation benefits, but your employer CAN count your workers’ compensation leave as FMLA leave if your injury qualifies and proper notice is given. FMLA (Family and Medical Leave Act) is a federal job protection law. Whereas workers’ compensation is a state-based system designed to pay medical expenses, wage replacement benefits (generally about 2/3 of your average weekly wage up to a state-imposed maximum), and certain disability benefits after a workplace injury or illness.

At Joye Law Firm Injury Lawyers, we know injured workers often feel outmatched against employers whose insurance carriers and claims administrators understand the system better than they do. Our approach is built around listening first, treating clients with dignity, standing up to powerful opponents, and staying focused on better results for the people we serve.

Why FMLA May Appear After a Workplace Injury

The Family and Medical Leave Act gives eligible employees up to 12 workweeks of unpaid, job-protected leave for qualifying family and medical reasons. It also requires that group health benefits continue under the same conditions as if the employee had continued working. After FMLA leave, employees must be restored to the same or a virtually identical position.

A workplace injury may qualify for FMLA leave if the employee is unable to work due to a serious health condition. A physical or mental condition may qualify if it requires ongoing treatment, a hospital stay, prescribed medication, physical therapy, or work restrictions that prevent the employee from performing essential functions.

So, HR may send FMLA paperwork after a workplace injury because the same medical condition can fit both systems.

When Workers’ Comp and FMLA Can Run Together

For FMLA and workers’ compensation to run concurrently, several factors usually need to align.

The employer must be a covered employer under the federal FMLA. Covered employers include private-sector employers with 50 or more employees in 20 or more workweeks, public agencies, and local educational agencies, such as public and private elementary or secondary schools.
The worker must be an eligible employee. Under federal FMLA, the employee must have worked for the covered employer for at least 12 months, have at least 1,250 hours of service during the 12 months before leave starts, and work at a location with at least 50 employees within 75 miles.
The work injury must qualify as a serious health condition. A minor injury that needs only basic first aid may not qualify. A back injury requiring treatment, surgery, several weeks away from work, or strict medical restrictions may qualify.

Using FMLA while on workers' compensation

What Your Employer Must Tell You in Writing

Your employer cannot silently drain your FMLA time. Once your employer has enough information to know that your leave qualifies as FMLA leave, they must provide you with a written designation notice. That notice must tell you that your leave will be counted as FMLA leave and, if known, state the amount of leave that will count against your FMLA entitlement.

Employers also must provide eligibility and rights notices. These notices should explain certification requirements, group health benefits, paid leave rules, and the leave year used to track FMLA time. If your employer informs you after the fact that your FMLA time has already been used, ask for the written designation notice and leave calculation. Keep copies of emails, letters, forms, and medical notes.

How South Carolina Workers’ Compensation Fits In

South Carolina workers’ compensation laws apply separately from federal FMLA. As a general rule, South Carolina businesses that regularly employ four or more employees must maintain workers’ compensation coverage.

Workers’ compensation benefits in South Carolina may include medical benefits, partial wage replacement benefits, and permanent disability benefits. The South Carolina Workers’ Compensation Commission states that there is no recovery for pain and suffering under the South Carolina Workers’ Compensation Act.

State law also has deadlines. An injured worker generally should report the accident to the employer as soon as practicable. No compensation is payable unless notice is given within 90 days after the accident or death, unless an exception applies. A workers’ comp claim is generally barred unless filed with the Commission within two years after the accident.

Medical Certification Can Affect Both Leave and Benefits

Your employer may require medical certification for FMLA leave. Federal regulations allow employers to request information such as the date the serious health condition began, its expected duration, medical facts supporting the need for leave, and information showing that the employee cannot perform essential functions of the job.

In a workers’ comp case, the employer or carrier may also receive certain medical information related to the work injury. Federal FMLA rules do not prevent an employer from complying with workers’ compensation provisions that permit requests for information from the workers’ compensation health care provider.

This is one reason injured workers should keep treatment records organized. Save work notes, restrictions, referrals, prescription medication records, therapy schedules, and any return-to-work instructions.

What Happens If Your FMLA Time Runs Out

One of the biggest misunderstandings injured workers have is believing that workers’ compensation itself protects their job. It does not. While South Carolina law protects employees from retaliation for filing a valid workers’ compensation claim, it does not require an employer to hold your position open indefinitely while you recover. Once FMLA job protection ends, an employer may be able to terminate your employment even though your workers’ compensation claim is still active.

Many injured workers don’t realize the FMLA clock may already be ticking while they’re focused on recovering. By the time they learn about it, much or all of their 12 weeks of job-protected leave may already have been used. That does not mean your employer can ignore other laws. If your injury leaves you with a disability, the Americans with Disabilities Act may require a separate review of reasonable accommodation, such as modified duty or an equivalent job, if you can perform essential functions with accommodation.

Light duty can also raise questions. Federal regulations state that an employer may offer light duty after a workers’ comp injury, but FMLA does not require the employee to accept light duty instead of taking FMLA leave. Before refusing or accepting light duty, speak with your doctor and review how the choice may affect wage benefits, medical treatment, and job protection.

Steps to Protect Your Leave and Workers’ Comp Claim

1. Keep Separate Files for FMLA and Workers’ Comp

Once FMLA enters a workers’ comp case, do not rely on verbal updates or assumptions. Treat every form, email, work note, and HR message as part of the record. A clear paper trail can help show when your injury was reported, what your doctor restricted you from doing, how your employer responded, and how your leave was counted.

Start by creating one file for your workers’ compensation claim and one file for your FMLA paperwork. Keep copies of the accident report, claim forms, medical notes, work restrictions, prescription records, physical therapy schedules, wage statements, mileage logs, and all messages from HR or the insurance carrier.

2. Confirm Phone Conversations in Writing

If a conversation happens by phone, write down the date, the person’s name, and what was said. Then send a short follow-up email confirming your understanding. This can help prevent later disputes about what HR, your supervisor, or the insurance adjuster told you.

3. Ask HR to Confirm Your Leave Status

Ask HR to put your leave status in writing. If your employer is counting your absence as FMLA leave, request the eligibility notice, rights and responsibilities notice, and designation notice. Federal guidance requires employers to inform employees of their FMLA rights and responsibilities, including when leave is designated as FMLA leave. This matters because your FMLA time should not disappear without a written explanation.

4. Track Your Remaining FMLA Time

Track your own FMLA balance. Do not assume payroll, HR, and the workers’ compensation adjuster are working from the same records. Ask how much FMLA time has been used, how much remains, and what date the employer says your job-protected leave will end. Keep that answer with your other documents.

5. Match Light Duty to Your Medical Restrictions

Follow your doctor’s restrictions closely. If your doctor says no lifting, no driving, no standing for long periods, or no return to work until a certain date, do not ignore those limits. If your employer offers light duty, ask for the job duties in writing and show them to your doctor before accepting. The goal is to avoid a mismatch between what your employer wants and what your medical condition allows.

6. Return Medical Certification Forms on Time

Respond to medical certification requests on time. FMLA regulations allow employers to require certification from a health care provider, including information about the condition, expected duration, and why the employee cannot perform job duties. Give the form to your provider promptly and keep a copy before returning it. If the form is incomplete, your employer may ask for a correction, so leave time for follow-up.

7. Watch for Changes in Wage or Medical Benefits

Watch for benefit changes. If your wage checks stop, your medical treatment is delayed, or the insurance carrier denies a recommended appointment, document the problem right away. Workers’ compensation benefits and FMLA leave are separate, so a dispute in one area should not be ignored just because another form of leave is active.

8. Confirm That a Workers’ Comp Claim Was Filed

Don’t assume a formal workers’ comp claim has been filed. Confirm it. The South Carolina Workers’ Compensation Commission explains that an injured worker must file a claim to protect the right to compensation, even if an employer’s representative also files paperwork after the accident. The Commission identifies Form 50 for workplace injury claims and notes the two-year filing deadline. However, notice must be provided well before that.

9. Read Every Document Before Signing

Before signing anything, read the document carefully. A return-to-work form, resignation, release, or settlement agreement can affect your claim. If the language is unclear, do not guess. Ask what the document does, who prepared it, and how it may affect medical care, lost income, future work restrictions, and disability benefits.

10. Get Help If the Process Starts to Feel One-Sided

Get legal guidance if the process starts to feel one-sided. Warning signs include pressure to return before your doctor clears you, sudden use of FMLA after a long absence, missing wage checks, denial of medical treatment, threats about your job, or confusion about light duty. At that point, speaking with Joye Law Firm Injury Lawyers can help you understand what is happening and what steps may protect your claim

Frequently Asked Questions

WC & FMLA

Can my employer fire me because I filed a workers’ compensation claim?

No. In South Carolina, an employer cannot legally fire or demote an employee simply for filing a workers’ compensation claim in good faith or for participating in a workers’ compensation proceeding. However, there are lawful ways in which an employer may fire an employee who is out on workers’ comp. They could say there is no position available that accommodates the worker’s injury-related disability or that the worker’s job performance does not meet established standards. That’s why it is important to have an attorney review your claim.

Will my health insurance continue if workers’ comp and FMLA overlap?

If your leave is covered by FMLA, your group health insurance should continue under the same terms as if you were still working. That usually means you will still be responsible for your normal share of the premium. Ask HR to explain in writing how premiums should be paid while you are out, especially if you are not receiving your regular paycheck.

Can I use sick leave or vacation while receiving workers’ comp benefits?

It depends on your employer’s policies, your leave status, and whether you are receiving workers’ compensation wage benefits. FMLA leave is unpaid, but paid leave may sometimes be used concurrently. Before using sick leave, vacation, or PTO, ask HR to confirm in writing how it will affect your leave balance, paycheck, and workers’ compensation benefits.

What if the workers’ comp doctor and my personal doctor disagree?

In South Carolina workers’ compensation cases, your employer or their insurance carrier control which doctor is authorized to treat your work injury. Your personal doctor’s opinion may still be helpful during your claim, but only treatment by your assigned workers’ compensation medical provider will be covered. That means you will be responsible for paying any costs incurred with your personal doctor. If you believe the authorized doctor is overlooking symptoms or releasing you too soon, do not simply ignore the restrictions or switch providers without guidance. Ask about a second opinion, a change of physician, or other steps to protect your medical care. We help clients with this exact scenario every day.

Does taking light duty mean my workers’ comp case is over?

No. Light duty usually means a doctor believes you can work within specific medical restrictions. It does not automatically end your workers’ compensation case. Depending on the facts, light duty may affect wage benefits, but medical treatment, work restrictions, and any permanent disability issues may still need to be addressed. Before accepting a light-duty assignment, ask for the duties in writing and ensure they align with your doctor’s restrictions.
