Is It Illegal to Work While on FMLA? Full 2026 Guide

Working while on FMLA is not automatically illegal. The Family and Medical Leave Act does not contain a specific criminal prohibition against employees performing any work during their leave period.

The legal picture is more complicated than that simple answer suggests. Whether working during FMLA crosses a legal or employment line depends entirely on what type of work you are doing, for whom, and whether your employer has a policy restricting outside employment during leave. Getting this wrong can cost you your job, your FMLA protection, and in some circumstances, much more.

Many employees mistakenly assume FMLA gives them total freedom to structure their time off however they choose. It does not. Employers retain significant rights during your FMLA period.

This article covers every scenario: second jobs, freelance work, working from home, intermittent leave, employer policies, FMLA fraud, and what disability benefits mean for this analysis.

Is It Illegal to Work While on FMLA?

Working while on FMLA is not a criminal offense under federal law. The Family and Medical Leave Act, codified at 29 U.S.C. Section 2601 et seq., does not make working during leave a crime.

The legal risks of working while on FMLA are employment-related, not criminal. Your employer may be able to terminate you, deny you FMLA benefits, or pursue a civil fraud claim. None of those are criminal prosecutions brought by the government.

The one scenario where criminal exposure can enter the picture is when working during FMLA intersects with disability insurance fraud or workers’ compensation fraud. If you are collecting short-term disability payments or workers’ comp while claiming an inability to work, and you are actually working, that can constitute fraud under state criminal statutes. The FMLA itself is not the source of that criminal liability; the insurance fraud statutes are.

Quick Facts:

• FMLA criminal prohibition on working: Does not exist
• Federal law making FMLA-leave working a crime: Does not exist
• Employer’s right to fire you for working during FMLA: Yes, if policy prohibits it
• FMLA fraud civil liability: Yes, employer can pursue recoupment of benefits
• Criminal exposure if disability benefits are involved: Yes, under state fraud statutes

The bottom line is that FMLA does not land you in handcuffs for working. But it can absolutely cost you your job, your leave protection, and potentially your insurance benefits.

Can You Work While on FMLA?

Whether you can work while on FMLA depends on your employer’s policies and whether the work is consistent with the medical reason for your leave. The FMLA statute itself does not prohibit all work during leave, but it also does not give you unlimited freedom to work as you choose.

The DOL’s regulations at 29 CFR Part 825 govern the practical implementation of FMLA. Under those regulations, employers are permitted to enforce their existing outside employment policies during FMLA leave. If your employer has a policy that employees cannot hold second jobs or perform outside work during any leave period, that policy applies to your FMLA leave as well.

The medical condition underlying your FMLA leave is also relevant. FMLA requires that you have a “serious health condition” that makes you unable to perform the functions of your position. If you are genuinely unable to perform your job’s functions but can perform different activities, that may be consistent with your FMLA qualification. But if working elsewhere demonstrates you are not as incapacitated as claimed, your employer has grounds to challenge your FMLA status.

What the regulations permit:

• Working in a capacity consistent with your medical restrictions during leave
• Continuing pre-existing outside employment that your employer permitted before leave (if employer policy allows)
• Performing activities not restricted by your serious health condition

What creates legal risk:

• Working a job that requires exactly the functions you claimed inability to perform
• Starting new outside employment during FMLA that your employer did not know about
• Violating an explicit employer policy prohibiting outside work during leave

Can You Work Another Job While on FMLA?

Working another job while on FMLA is not automatically illegal, but it can get you fired if your employer’s policy prohibits outside employment during leave. The legal authority for this is 29 CFR 825.216(e), which explicitly states that employers may apply established, uniformly-applied policies governing outside or supplemental employment during FMLA leave.

The key phrase is “established, uniformly-applied.” Your employer cannot create a new rule on the spot just to target you for working elsewhere during FMLA. The outside employment policy must have existed before your leave, and the employer must apply it consistently to all employees, not selectively to people on FMLA.

If your employer does not have an outside employment policy, the legal landscape is different. Without a policy restricting second jobs, your employer has a much weaker basis for terminating you simply because you worked elsewhere during leave. However, if the second job demonstrates that your medical condition was misrepresented, that remains a separate problem.

Key Takeaway: The FMLA statute itself does not ban second jobs during leave, but your employer’s outside employment policy can make working another job a terminable offense even when the underlying FMLA leave is valid.

Working During FMLA Leave: What the Law Says

The FMLA statute at 29 U.S.C. Section 2614 gives employees the right to be restored to their position upon return from leave. The statute protects against interference with FMLA rights and against retaliation for taking leave. It does not address working during leave except through the DOL’s regulatory framework at 29 CFR Part 825.

The regulatory framework sets the following key rules regarding working during FMLA leave. Employers may enforce their existing outside employment restrictions. Employers cannot deny FMLA solely because an employee has another job, unless an applicable policy prohibits it. The employer bears the burden of proving a uniformly-applied policy existed before the leave began.

The statute also addresses a specific scenario called “reduced leave schedule” FMLA, where an employee works a reduced number of hours rather than taking full weeks off. Under a reduced leave schedule, an employee might work 20 hours per week instead of 40. This is a form of FMLA leave, not a work-around to it, and the hours worked do not count against the 12-week entitlement.

How FMLA regulations address working:

• 29 CFR 825.216(e): Allows enforcement of outside employment policies during FMLA
• 29 CFR 825.204: Governs reduced leave schedules and intermittent leave
• 29 CFR 825.310: Addresses fitness-for-duty certification upon return
• 29 U.S.C. 2615: Anti-retaliation provisions protecting employees who take FMLA

The law creates a framework where working is neither categorically banned nor categorically permitted during FMLA leave. The specific facts of each situation determine the legal outcome.

FMLA Fraud and Working: Where the Line Is

FMLA fraud refers to misrepresenting a medical condition to obtain leave you do not legitimately need or to use that leave in a way inconsistent with the stated medical reason. Working while on FMLA can be evidence of FMLA fraud, but working alone does not automatically constitute fraud.

The fraud analysis centers on consistency. If you took FMLA leave claiming you cannot sit at a desk for eight hours due to a back injury, and you spend your FMLA days working a landscaping job that involves heavy lifting, that inconsistency is strong evidence of fraud. The FMLA certification stated one thing; your actual physical capacity demonstrated another.

If, however, you took FMLA leave for a mental health condition that limits your ability to handle the stress of your primary job but does not prevent you from performing lower-stress work elsewhere, the fraud analysis is less clear. Courts and employers look at whether the work performed during leave is consistent with the medical restrictions documented in the FMLA certification.

Factors that indicate FMLA fraud:

• Working a job that requires the exact functions you claimed inability to perform
• Working full-time hours at another job while claiming full incapacitation
• Working during periods of FMLA leave without any medical improvement
• Using FMLA leave days for activities clearly unrelated to medical treatment or recuperation
• Falsifying FMLA medical certifications to obtain leave

Factors that do not necessarily indicate fraud:

• Working a different type of job that does not require the restricted functions
• Self-employment tasks that can be performed within medical restrictions
• Part-time or reduced-hours work consistent with a reduced capacity
• Working during a period of intermittent FMLA on non-designated leave days

What Happens If You Work While on FMLA?

The consequences of working while on FMLA depend on whether your employer has a policy against outside employment, whether the work is consistent with your medical condition, and whether disability or workers’ compensation benefits are also involved.

In the most common scenario, an employer discovers that an employee on FMLA leave is working another job. If the employer has an outside employment policy and can show it was uniformly applied, the employer can terminate the employee. The FMLA leave does not protect the employee from this termination because the termination is based on a legitimate policy violation, not on the fact of taking FMLA leave.

If the employer does not have an outside employment policy, they may still investigate whether the employee’s medical condition was genuine. They can require a fitness-for-duty certification upon return and can challenge the FMLA certification if new evidence suggests the medical claim was overstated.

Possible outcomes when working during FMLA is discovered:

• Termination based on violation of outside employment policy: Most common consequence
• FMLA designation revoked: Leave reclassified as unauthorized absence
• Civil lawsuit by employer: Recovery of any paid leave benefits provided fraudulently
• DOL investigation: If employer violated FMLA in response; DOL can investigate employer conduct too
• Workers’ compensation fraud charges: If applicable insurance was also involved
• Short-term disability benefit recovery demand: Insurance company demands return of payments

The last two outcomes involve criminal or quasi-criminal exposure that goes beyond FMLA itself and into insurance fraud territory.

Can Your Employer Fire You for Working While on FMLA?

Yes, your employer can legally fire you for working another job while on FMLA if they have an outside employment policy that prohibits it. The termination does not violate FMLA as long as the policy was established before the leave, applied uniformly, and the termination would have happened to any employee who violated it regardless of their leave status.

The FMLA anti-retaliation provision at 29 U.S.C. Section 2615 protects employees from being fired for taking FMLA leave. But it does not protect employees from being fired for policy violations that happen to occur during FMLA leave. Courts distinguish between termination because of FMLA leave and termination because of a legitimate policy violation that occurred during leave.

Employers who want to discipline an employee for working during FMLA should be careful to document their outside employment policy clearly, show it predated the leave, and demonstrate consistent enforcement across all employees regardless of leave status.

Employer’s checklist for lawful termination during FMLA:

For more context, see Is It Illegal to Walk Around Without ID? 2026 Laws

• Written outside employment policy existed before FMLA leave began
• Policy applies to all employees, not just those on FMLA
• Employee was aware of the policy before taking leave
• Policy violation is clearly documented with evidence
• Termination decision is not based on the FMLA leave itself
• Same action would be taken against any other employee for the same violation

Employees who are fired during FMLA leave and believe the termination was actually retaliatory can file a complaint with the DOL’s Wage and Hour Division or pursue a private civil lawsuit under 29 U.S.C. Section 2617.

FMLA Fraud Consequences

FMLA fraud consequences are primarily civil in nature at the federal level. There is no federal criminal statute specifically titled “FMLA fraud.” The consequences flow through employment law, civil courts, and insurance fraud statutes where applicable.

At the employment level, FMLA fraud gives an employer grounds to terminate the employee and to pursue recovery of any wages, paid leave benefits, or employment continuation expenses that were provided based on the fraudulent FMLA claim. Courts have upheld such recoveries when employers can demonstrate that the FMLA certification was materially false.

At the insurance level, if the employee was simultaneously collecting short-term disability benefits from an employer-sponsored or private disability insurance plan while working, the insurance company can demand full repayment of benefits paid during the fraudulent period. If the employee made affirmative false statements to obtain those benefits, state insurance fraud criminal statutes may apply.

The criminal exposure is real but indirect. FMLA itself does not create criminal liability. The insurance and workers’ compensation fraud statutes that attach to the same scenario are where criminal charges originate.

Key Takeaway: FMLA fraud is primarily a civil and employment matter, but when disability or workers’ compensation benefits are simultaneously involved, state criminal fraud statutes add genuine criminal exposure on top of the employment consequences.

Intermittent FMLA and Working Another Job

Intermittent FMLA creates the most legally complicated scenario for employees who also work another job. Intermittent FMLA allows an employee to take leave in separate blocks of time or by reducing their normal weekly or daily work schedule.

Under intermittent FMLA, an employee might work Monday, Wednesday, and Friday for their primary employer while taking FMLA on Tuesday and Thursday. If that same employee also works Tuesday and Thursday at a second job, the legal picture depends entirely on their employer’s policies and the nature of their medical condition.

The medical condition analysis is particularly acute with intermittent leave. If your FMLA is for chemotherapy appointments on certain days, working another job on those same days would be very strong evidence that your FMLA certifications are fraudulent. If your FMLA is for a condition that flares unpredictably and limits certain specific functions, working a different type of job on some of those days may be consistent with your medical restrictions.

Intermittent FMLA and second job scenarios:

Documentation is critical with intermittent FMLA. Employees who work another job during intermittent FMLA should be able to demonstrate that the work was within their documented medical restrictions for that period.

Working From Home While on FMLA

Working from home while on FMLA occupies a particularly gray area because the line between legitimate rest-based recuperation and actual work performance is not always visible. Whether working from home violates FMLA rules depends on whether you are doing so for your primary employer or for another employer, and whether your employer authorized it.

Working from home for your primary employer during FMLA leave is generally not permitted unless your employer specifically requests it and you voluntarily agree. An employer cannot require an employee to work during FMLA leave. If an employer pressures an employee to perform work tasks remotely during leave, that pressure may constitute interference with FMLA rights under 29 U.S.C. Section 2615.

Working from home for a different employer during FMLA leave follows the same outside employment analysis. If your employer’s policy prohibits outside employment and the work-from-home activity is for another employer, the policy violation is the same whether you are physically present at their office or working from your couch.

Work-from-home during FMLA scenarios:

• Answering occasional emails from your primary employer: Gray area; not recommended; could be treated as working
• Performing assigned tasks for primary employer while on leave: Violates FMLA if employer required it; may waive leave protections if voluntary
• Remote work for a second employer: Subject to outside employment policy analysis
• Self-employment tasks from home: Analyzed under the self-employment during FMLA framework
• Administrative activities related to medical care: Not work; not prohibited

Employees who feel pressured to work remotely during FMLA leave should document those communications and understand that the employer’s request to perform work while on FMLA is itself a potential FMLA violation.

Can You Work for Yourself While on FMLA?

Working for yourself, meaning self-employment or freelance work, while on FMLA is not automatically prohibited, but it faces the same two-part analysis as any other work during leave: employer policy and medical condition consistency.

On the employer policy side, some outside employment policies explicitly cover self-employment, freelance work, and consulting activities. If your employer’s policy says “employees may not engage in any outside employment or self-employment during leave periods,” then freelancing during FMLA violates that policy.

On the medical consistency side, self-employment work that requires exactly the functions you cannot perform in your primary job is problematic. If you took FMLA for a psychiatric condition that prevents you from handling the demands of your corporate finance position, writing occasional freelance articles or doing light consulting may be consistent with your restrictions. If you took FMLA for a physical injury that prevents computer work, running a web design business from home on FMLA days creates serious inconsistency problems.

Self-employment during FMLA analysis:

• Existing self-employment business that predates FMLA: Lower risk if disclosed to employer and policy permits
• New freelance work started during FMLA: Higher risk regardless of medical consistency
• Work consistent with medical restrictions: More defensible
• Work inconsistent with stated medical limitations: Significant fraud risk
• Disclosed to employer versus undisclosed: Disclosure significantly reduces termination risk

The key risk differentiator is disclosure. An employee who informs their employer that they have pre-existing self-employment and asks about the outside employment policy before going on leave is in a much stronger position than one who secretly starts freelancing during leave.

FMLA and Outside Employment Policies

FMLA and outside employment policies interact under 29 CFR 825.216(e), which is the specific regulatory provision that allows employers to enforce their existing outside employment policies during FMLA leave. Understanding this regulation is essential for both employees and employers.

The regulation requires that the outside employment policy be an existing, uniformly-applied policy. It cannot be created in response to a specific employee’s FMLA leave. It must apply equally to employees on FMLA leave and to employees on any other type of leave. An employer who allows employees on personal leave to hold second jobs but terminates employees on FMLA for the same conduct is likely violating the FMLA’s anti-discrimination provisions.

The “uniformly applied” requirement is the most common ground for employee challenges to FMLA-related terminations based on outside employment. If an employer can be shown to have applied the policy selectively, enforcing it against FMLA leave-takers but not against others, the termination can be characterized as FMLA retaliation.

What makes an outside employment policy legally enforceable during FMLA:

• Policy was written and in effect before the employee’s leave began
• Policy has been applied consistently to all employees, not just FMLA takers
• Employee had actual or constructive knowledge of the policy before taking leave
• Policy is reasonable and not specifically designed to target FMLA leave-takers
• Employer can document both the policy and its consistent enforcement history

Employees who suspect a policy is being selectively enforced against them because of FMLA leave have a legal avenue through the DOL’s Wage and Hour Division complaint process.

FMLA Leave and Second Job Rules

The rules governing second jobs during FMLA leave are a product of three overlapping frameworks: the FMLA statute’s anti-retaliation protections, the DOL’s outside employment regulation at 29 CFR 825.216(e), and the employer’s specific written policies.

No single rule applies to all employees in all situations. An employee at a company with no outside employment policy is in a different legal position than one at a company with a strict moonlighting prohibition. Both are governed by the FMLA, but the practical outcomes differ significantly.

The practical rules employees should understand before working a second job during FMLA:

• Review your employer’s handbook for any outside employment or moonlighting policy
• Check whether that policy applies during leave periods, not just during active employment
• Assess whether the second job’s physical and cognitive demands are consistent with your medical condition
• Consider whether taking the second job would be inconsistent with your FMLA certification
• Evaluate whether the second job income affects any disability or leave benefits you are receiving
• Decide whether to disclose the second job to your employer proactively

Proactive disclosure, while not legally required, is the single most effective risk-reduction strategy for employees who want to work a second job during FMLA leave. An employer who is informed upfront has less legal basis for claiming deception if the issue arises later.

FMLA Working for Same Employer

Working for the same employer while on FMLA leave is generally prohibited unless the employer specifically requests it and you agree voluntarily. The FMLA was designed to give employees protected time away from their employment responsibilities. Employers who require work during FMLA are interfering with the leave entitlement.

The practical reality is that some employers, particularly in knowledge worker environments, send emails, make calls, or ask employees on FMLA to review documents. Employees who respond to these requests are technically performing work during FMLA leave. This can create complications if the employer later tries to claim that the employee was not actually on leave.

Employees who receive work-related contacts from their employer during FMLA leave should respond by noting that they are on FMLA and will not be available to perform work tasks. Documenting these interactions protects the employee if a dispute arises about whether genuine leave was taken.

When same-employer work during FMLA creates problems:

• Employer can argue leave was not genuinely taken if employee performed substantial work tasks
• Employee’s FMLA leave bank may be reduced based on work performed
• Employer may claim leave was used inconsistently with its stated medical purpose
• Employee may inadvertently waive leave protections by continuing to perform employment functions

The DOL has made clear in guidance that an employer cannot require work during FMLA leave. Voluntary performance of minimal tasks may not affect leave status, but regular work performance during leave undermines the leave’s legal integrity.

Working While on FMLA and Disability Benefits

The most legally dangerous combination in this entire topic is working while on FMLA and simultaneously collecting disability benefits. This is where civil employment consequences can escalate into genuine criminal exposure.

Short-term disability insurance typically requires that the covered employee be unable to perform their occupation or any occupation, depending on the policy definition, due to their medical condition. If you are collecting disability benefits and working any job, you may be violating your disability policy’s terms and potentially committing insurance fraud.

Workers’ compensation benefits carry similar restrictions. Most workers’ comp systems require that the injured employee not work during a period of total disability. Working while collecting total disability workers’ comp benefits is workers’ compensation fraud, which is a criminal offense in every state. Penalties range from misdemeanor to felony depending on the amount involved and the state’s statute.

Benefit types and working restrictions:

The intersection of FMLA and disability benefits requires employees to understand all the programs they are enrolled in before making any decision about working during leave.

Employer FMLA Policies on Outside Employment

Employer FMLA policies on outside employment are the practical mechanism through which most working-during-FMLA conflicts are resolved. A well-drafted employer policy creates clear rules that protect the employer’s ability to enforce consistent standards. A poorly drafted or selectively enforced policy creates legal vulnerability for the employer.

The DOL’s FMLA regulations allow employers to maintain and enforce outside employment policies during FMLA leave as long as those policies are uniformly applied. Employers should document their outside employment policies clearly in their employee handbook, train supervisors on consistent enforcement, and ensure the policy predates any specific employee’s leave situation.

Employees should understand that the employer’s policy, not their personal assessment of whether working seems reasonable, is what governs their legal exposure. An employee who genuinely believes their part-time freelance work is harmless but whose employer has a clear written policy against outside employment during leave is still at legal risk.

What a compliant employer outside employment policy should include:

• Clear statement of the prohibition during all types of leave, including FMLA
• Definition of “outside employment” that addresses self-employment and freelancing
• Disclosure requirement so employees can report pre-existing outside jobs
• Consistent enforcement history documented through HR records
• Statement of consequences for violation
• Application to all employees regardless of leave type

Employees reviewing their employer’s FMLA policy should specifically look for sections addressing outside employment, moonlighting, or second jobs. If the policy is ambiguous, seeking HR clarification in writing before taking leave is the most protective approach.

Frequently Asked Questions

Is it illegal to work while on FMLA leave?

No, working while on FMLA is not a federal crime.
The FMLA statute does not criminalize working during leave; the legal consequences are employment-related and civil in nature.
Criminal exposure only arises when disability insurance or workers’ compensation fraud statutes are also implicated, and that liability comes from those separate statutes, not from FMLA itself.

Can your employer fire you for working another job while on FMLA?

Yes, your employer can legally fire you for working another job during FMLA if they have an established, uniformly-applied outside employment policy.
The termination does not violate FMLA as long as it is based on the policy violation and not on the fact that you took FMLA leave.
Employers who selectively enforce the policy only against FMLA takers may face retaliation claims.

What is FMLA fraud and what are the consequences?

FMLA fraud means misrepresenting a medical condition to obtain leave you do not legitimately need or using leave in ways inconsistent with your stated medical condition.
Consequences include termination, employer civil claims for return of paid benefits, and potential insurance fraud charges if disability payments were also involved.
There is no specific federal criminal statute for FMLA fraud; the criminal exposure comes from state insurance fraud laws when benefits are involved.

Can you work for yourself or freelance while on FMLA?

Working for yourself during FMLA is not automatically prohibited, but it faces the same analysis as any outside employment.
Your employer’s outside employment policy applies to freelancing and self-employment, and the work must be consistent with the medical restrictions documented in your FMLA certification.
Disclosing pre-existing self-employment to your employer before taking leave significantly reduces your legal risk.

Does working while on FMLA affect your disability benefits?

Yes, working while collecting short-term disability or workers’ compensation benefits is typically prohibited under those benefit programs and can constitute insurance fraud.
The disability benefit restrictions are separate from FMLA and often more strict; most disability policies require that you be unable to work to receive benefits.
Employees who work during FMLA while also collecting disability benefits face benefit repayment demands and potential criminal fraud charges under state law.

Closing

Working during FMLA is one of those situations where the legal answer is technically straightforward but the practical reality is anything but simple. The law does not criminalize working, but your employer’s policy, your medical certification, and any benefits you are collecting can each create serious independent consequences.
