FMLA Meaning: What the Family and Medical Leave Act Means for Employers

The first time an employee asked me about FMLA, I panicked. I had 22 employees and no idea whether the law applied to my business, what I was required to do, or what would happen if I got it wrong. I spent an evening reading the Department of Labor's FMLA page and discovered two things: first, FMLA did not apply to my business because I had fewer than 50 employees, and second, my state had its own family leave law that did apply, and I had been ignoring it.

That experience is universal among small business owners. FMLA is the most well-known employment leave law in the United States, but most small business owners do not understand where it starts, where it stops, and what fills the gap when it does not apply. This guide covers what FMLA means, who it covers, how it works for employers who are covered, what employers under 50 employees should do instead, which state laws apply at lower thresholds, and how to handle the transition when your business approaches the 50-employee mark. FirstHR manages the documentation and leave tracking that FMLA compliance requires, but this guide is about understanding the rules.

What Is FMLA?

The Family and Medical Leave Act (FMLA) is a federal law enacted in 1993 that provides eligible employees with up to 12 weeks of unpaid, job-protected leave per year for specified family and medical reasons. During FMLA leave, the employer must maintain the employee's group health insurance coverage on the same terms as if the employee had continued to work. When the employee returns from leave, the employer must restore them to the same or an equivalent position.

Three key facts employers need to understand immediately. First, FMLA leave is unpaid. The employer is not required to pay the employee during leave (though the employer may require substitution of accrued paid leave). Second, FMLA leave is job-protected. The employee must be returned to the same or equivalent position when they come back. Third, FMLA applies only to covered employers with 50 or more employees. If you have fewer than 50 employees, federal FMLA does not create obligations for your business, but state laws may.

Who Is Covered by FMLA

FMLA coverage has two sides: the employer must be a "covered employer," and the employee must be an "eligible employee." Both conditions must be met for FMLA to apply.

For private-sector employers, the 50-employee threshold is the critical number. If you have 50 or more employees for at least 20 workweeks (not necessarily consecutive) in the current or preceding calendar year, you are a covered employer. Part-time employees, temporary employees, and employees on leave all count toward the 50. The full-time hours guide covers how full-time and part-time classifications work.

Employee Eligibility Requirements

Even at a covered employer, not every employee is eligible for FMLA leave. The employee must meet all four of the following requirements at the time they request leave.

The 75-mile radius requirement is the one that surprises employers with distributed teams. If you have 60 employees total but they are spread across offices in three cities, none of which has 50 employees within 75 miles, FMLA may not apply to any of them. The DOL Employer's Guide to FMLA provides detailed guidance on how to calculate the 75-mile radius for remote and multi-site employers.

Qualifying Reasons for FMLA Leave

An eligible employee may take FMLA leave for any of the following reasons. The employer cannot add or subtract from this list. If the reason qualifies, the leave must be granted.

How FMLA Leave Works: The Employer's Workflow

When an eligible employee requests FMLA leave, the employer must follow a specific process. Deviating from this process, even unintentionally, creates liability.

The DOL provides standardized forms for each step of this process. Using them is not legally required, but it demonstrates compliance and creates an audit trail. The HR document management guide covers how to store leave-related records within your broader employee file system.

What Covered Employers Must Do

The retaliation prohibition is the obligation that generates the most litigation. Employers who terminate an employee shortly after FMLA leave, even for legitimate performance reasons, face a strong inference of retaliation. The timing creates circumstantial evidence that is difficult to overcome without pre-leave documentation of the performance issues. The SHRM FMLA resource hub provides additional guidance for HR practitioners managing FMLA compliance. The retaliation guide covers the broader framework for preventing retaliation claims.

FMLA Forms and Paperwork: Which Forms You Need

The DOL provides standardized forms for each step of the FMLA process. Using the official forms is not legally required, but it demonstrates compliance, ensures you collect the right information, and creates a defensible audit trail. All forms are available for free download from the DOL FMLA forms page.

The most common paperwork sequence for a standard FMLA leave request: the employee notifies you of the need for leave, you send WH-381 within 5 business days, the employee returns WH-380-E or WH-380-F within 15 calendar days, and you send WH-382 within 5 business days of having sufficient information. Store all completed forms in a confidential medical file separate from the employee's general personnel file. At FirstHR, document management stores these forms with timestamped audit trails and access controls that keep medical records separate from general employee files.

Under 50 Employees: What Applies Instead of FMLA

If your business has fewer than 50 employees, federal FMLA does not apply to you. This does not mean you have no leave obligations. Three categories of requirements may still apply to your business.

The most common mistake for employers under 50: assuming that no FMLA means no leave obligations. In practice, the patchwork of state laws, ADA accommodations, pregnancy protections, and workers' comp coverage creates leave obligations for nearly every employer regardless of size. Document whatever leave policy you adopt in your employee handbook and communicate it during onboarding. The workers' compensation guide covers the insurance and compliance requirements that apply to all employers. The onboarding checklist maps all compliance deadlines across the first 90 days.

State Family and Medical Leave Laws

Several states have enacted their own family and medical leave laws, many of which apply to employers smaller than the FMLA's 50-employee threshold. Some states also provide paid family leave, which FMLA does not. If you have employees in any of these states, the state law applies in addition to (or instead of) FMLA.

When both FMLA and a state program apply (employer has 50+ employees in a state with paid leave), the leaves typically run concurrently. The employee receives wage replacement from the state program while FMLA provides job protection. The employer cannot require the employee to choose one or the other. The compliance hub provides state-by-state guides with detailed leave law requirements for all 50 states plus DC.

Approaching 50 Employees: When to Start Preparing

If your business is growing toward 50 employees, you need to prepare for FMLA compliance before you hit the threshold, not after. The 50-employee count includes all employees (full-time and part-time) who were on the payroll for at least 20 workweeks in the current or preceding calendar year.

The part-time hours guide covers how part-time employee hours factor into the FTE calculation, which is relevant because part-time employees count toward the 50-employee FMLA threshold even though they may not individually qualify for FMLA leave (if they have not worked 1,250 hours).

Intermittent FMLA Leave: The Employer's Challenge

Intermittent FMLA leave is the most operationally difficult type for employers to manage. Instead of taking 12 consecutive weeks off, the employee takes leave in separate blocks: a day here, a few hours there, an unpredictable pattern driven by medical need.

The employer's primary tool for managing intermittent leave: require recertification. The employer can request recertification every 30 days (or more frequently if the employee requests an extension, the circumstances change, or the employer receives information casting doubt on the reason for leave). The employer can also require the employee to see a second or third health care provider (at the employer's expense) to verify the medical necessity. The HR metrics guide covers how to track leave usage alongside other workforce metrics.

Common FMLA Mistakes Employers Make

The most expensive mistake on this list: not recognizing an FMLA request. An employee who tells their manager "I need to take care of my mom, she just had surgery" has made an FMLA request, even though they never used the word FMLA. If the manager does not escalate it, the employer has interfered with the employee's FMLA rights. The HR rules and regulations guide covers the broader federal compliance framework including FMLA notice requirements.
