The Family and Medical Leave Act (FMLA) is one of the most important federal laws protecting employees who need time away from work for health, family, or caregiving reasons. It ensures eligible workers can take unpaid, job-protected leave without fear of losing their position or benefits. But one question often arises for both employees and employers alike: can someone work while on FMLA?

The answer depends on the type of work being performed, the purpose of the leave, and the employer’s policies. In many cases, working while on FMLA can conflict with the law’s intent, but there are limited exceptions. Understanding the rules helps employers maintain compliance and ensure their teams use leave appropriately and fairly.

Understanding the Purpose of FMLA

FMLA was designed to provide employees with up to 12 weeks of unpaid, job-protected leave within a 12-month period for specific medical or family-related reasons. These include serious health conditions, caring for an ill family member, bonding with a newborn or newly adopted child, or certain military-related family situations. During this time, the employee’s job and health benefits are protected, though wages are not required to be paid.

The intent of FMLA is to give employees time to recover or care for loved ones without the pressure of work. Because of this, the law assumes that the employee is not working during their leave period. If someone performs work for the employer while on FMLA, it may undermine the purpose of the law and create potential compliance issues.

General Rules About Working While on FMLA

In most cases, employees are not allowed to work while on FMLA leave. Performing work duties during this time contradicts the purpose of the leave, which is to rest, recover, or provide care. If an employee works, even remotely or part-time, during a full FMLA absence, the employer could argue that the employee is not truly on leave, which could jeopardize their job protection.

However, there are important nuances to consider. For example, if an employee is on intermittent FMLA leave, meaning they only take time off as needed for treatment or flare-ups, they can work during the periods they are not using FMLA hours. This flexibility allows employees with chronic conditions or ongoing medical needs to remain productive while still receiving the protection they need.

Employers should clearly define how intermittent leave is tracked and ensure that HR systems accurately record the hours taken. Communication between managers, HR, and employees is key to preventing misunderstandings about when an employee is considered “on leave” versus “at work.”

Working for Another Employer During FMLA

One of the most common compliance concerns arises when an employee on FMLA performs work for another employer or personal business. Unless approved by policy, this behavior can be considered a violation of FMLA or company policy. Employers have the right to enforce reasonable restrictions to prevent abuse, especially if the outside work conflicts with the purpose of the leave or the employee’s recovery.

For instance, if an employee takes FMLA leave due to a serious back injury but works physically demanding shifts for another employer during that same time, it may indicate misuse of FMLA. Employers can investigate potential abuse, but they must proceed carefully to avoid claims of retaliation or interference. The focus should remain on objective evidence and consistent enforcement of policy.

That said, not all external work automatically violates FMLA. If company policy permits outside employment and the work does not interfere with the medical reason for leave, it may be allowed. Each case should be reviewed individually, considering both the medical documentation and the organization’s rules about secondary employment.

Remote Work and Light Duty During FMLA

In an era of hybrid and remote work, the question of whether an employee can perform limited tasks while on FMLA has become increasingly relevant. Generally, if an employee is on continuous FMLA leave, they should not be performing work tasks, even remotely. The U.S. Department of Labor (DOL) has made it clear that working from home during FMLA leave is still considered “work” under the law, as it benefits the employer.

However, light-duty arrangements, where an employee returns to modified or reduced work, are possible after FMLA leave concludes. Light duty is typically offered as an accommodation under the Americans with Disabilities Act (ADA) or workers’ compensation, not FMLA. The key difference is that FMLA protects leave from work, while light duty provides a return-to-work option for those who are medically cleared for limited duties.

Employers must avoid pressuring employees to perform work tasks during FMLA leave, as even minor requests, like checking emails or joining short meetings can constitute interference under federal law. A best practice is to set clear boundaries about communication expectations before the employee’s leave begins.

Employer Responsibilities and Compliance Considerations

Employers play a vital role in managing FMLA compliance. HR professionals must ensure that policies are well-documented, consistently enforced, and clearly communicated. If an employee performs unauthorized work while on FMLA, the employer may take appropriate disciplinary action, provided it aligns with established policy and past practices.

At the same time, employers must respect employees’ FMLA rights and avoid retaliation or punitive measures for legitimate leave usage. Conducting fair investigations, documenting evidence, and consulting legal or HR experts when needed can help prevent compliance issues.

It’s also important to maintain accurate leave records. Many FMLA violations stem from administrative errors, such as improper time tracking or inconsistent approval processes. Automated systems can reduce this risk by providing a clear audit trail of leave requests, approvals, and usage patterns. This transparency protects both employees and the employer.

Understanding Exceptions and Flexibility

There are limited exceptions in which an employee may engage in some form of work-related activity during FMLA leave. These exceptions typically involve voluntary light-duty arrangements after medical clearance, intermittent leave situations, or company-approved external work that does not interfere with recovery or caregiving responsibilities.

Each exception must be handled carefully and documented thoroughly. Employers should ensure that any arrangement does not compromise the intent of FMLA or create inconsistencies in policy enforcement. Consulting with HR or legal advisors before approving such situations can help mitigate risk.

Ultimately, clear communication is the best safeguard. Employees should fully understand that FMLA leave is intended to protect their health and well-being, not to provide flexibility for other forms of work.
