FMLA eligibility determines who can use the federal Family and Medical Leave Act’s job-protected leave. The law does not create a universal paid-leave program, and it does not cover every worker, employer, or reason for an absence. Its protections apply when several separate requirements line up.

The four questions behind FMLA eligibility

A useful eligibility analysis separates four issues: whether the employer is covered, whether the employee meets the service and worksite tests, whether the reason for leave qualifies, and whether the notice and documentation rules are satisfied. Meeting the hours requirement alone does not establish a right to FMLA leave.

1. Is the employer covered?

The FMLA covers private employers that employed at least 50 employees for at least 20 workweeks in the current or preceding calendar year. Public agencies and public or private elementary and secondary schools are covered regardless of the number of employees they employ.

Employer coverage and employee eligibility are related but distinct. A small public agency may be a covered employer, for example, while an individual employee can still fail the 50-employees-within-75-miles worksite test.

2. Has the employee met the service requirements?

For most workers, the employee must have worked for that employer for at least 12 months and completed at least 1,250 hours of service during the 12 months immediately before leave begins. The 12 months generally need not be consecutive, although a break in service of seven years or more usually does not count unless a regulatory exception applies.

The hours test counts hours actually worked under Fair Labor Standards Act principles, not paid time that was not worked, such as many vacation, holiday, or sick-leave hours. Airline flight crew employees have a special eligibility formula, and qualifying military service protected by USERRA can count toward the months-and-hours tests.

3. Does the worksite test apply?

For most employees, the employer must employ at least 50 employees within 75 miles of the employee’s worksite. The distance is measured by surface miles over public streets, roads, highways, and waterways along the shortest route.

For a remote employee, the worksite is generally the office to which the employee reports or from which assignments are made, not the employee’s home. That rule can make the worksite calculation different from a simple count of people who physically work nearby.

4. Is there a qualifying reason?

Federal FMLA leave can cover the birth of a child and bonding, placement of a child for adoption or foster care and bonding, care for a spouse, child, or parent with a serious health condition, or the employee’s own serious health condition that makes the employee unable to perform essential job functions. It can also cover certain qualifying exigencies connected to a spouse’s, child’s, or parent’s covered military deployment and military caregiver leave for a covered servicemember or qualifying veteran.

Eligibility does not mean every medical appointment or family need qualifies. The statute and regulations define such terms as “serious health condition,” “spouse,” “parent,” and “son or daughter,” and those definitions shape whether a particular category of leave is protected.

How much leave the federal law protects

An eligible employee may generally take up to 12 workweeks of FMLA leave during the employer’s chosen 12-month measurement period. A person who normally works 32 hours a week generally has a 32-hour FMLA workweek, so the entitlement reflects the employee’s usual schedule rather than automatically equaling 480 hours.

When medically necessary, leave for a serious health condition or military caregiver reason may be taken intermittently or on a reduced schedule. Intermittent leave for bonding with a newborn or newly placed child generally requires the employer’s agreement, and bonding leave must conclude within 12 months after birth or placement.

Military caregiver leave is different: an eligible employee may receive up to 26 workweeks during a single 12-month period. The combined total of military caregiver leave and other FMLA leave in that period cannot exceed 26 workweeks.

What “job-protected” means

During FMLA leave, an employer must maintain group health coverage on the same terms that would have applied if the employee had continued working. At the end of protected leave, the employee generally must be restored to the same job or an equivalent job with equivalent pay, benefits, and other terms and conditions.

The FMLA prohibits an employer from interfering with, restraining, or denying rights under the Act and from retaliating against a person for exercising those rights. These protections do not create greater job rights than the employee would have had without taking leave.

FMLA is usually unpaid, but paid time can overlap

The federal entitlement is generally unpaid. An employee may choose, or an employer may require, available paid leave to be substituted under the applicable rules so that paid time and FMLA protection run concurrently.

This federal baseline does not displace more protective state family-and-medical-leave laws. State programs and employer benefits may use different eligibility rules, family definitions, payment structures, and procedures; the planned guide to FMLA and paid leave addresses that distinction in more depth.

How the FMLA leave process starts

An employee does not need to use the letters “FMLA” when first giving notice, but must provide enough information for the employer to understand that the absence may qualify. When the need for leave is foreseeable, at least 30 days’ advance notice is generally required; when 30 days is not practicable, notice must be given as soon as practicable.

Once an employer learns that leave may be FMLA-qualifying, it generally must provide an eligibility notice within five business days. If the employee is ineligible, the notice must state at least one reason, such as insufficient service time or hours.

The employer may request certification for a serious health condition, qualifying exigency, or military caregiver leave. Department of Labor forms are optional; a complete and sufficient certification in another format cannot be rejected merely because it is not on the employer’s preferred form.

Eligibility and designation are not the same decision. Eligibility asks whether the worker meets the threshold tests, while designation decides whether a particular absence is counted as FMLA leave after the employer has enough information.

Special situations that can change the calculation

• Separate periods of employment: Earlier employment may count toward the 12-month test, subject to the rule for breaks of seven years or more and its exceptions.
• Remote work: The reporting or assignment office is generally the worksite used for the 50-within-75-miles test.
• Military service: USERRA-protected service can be credited when determining FMLA eligibility.
• Airline flight crews: Federal law uses a specialized hours-of-service test instead of the ordinary 1,250-hour rule.
• Federal employees: Many federal workers receive family-and-medical-leave rights under Title 5 rules administered by the Office of Personnel Management rather than the private-sector FMLA provisions administered by the Department of Labor.

Where this page fits in the FMLA hub

This page focuses on federal eligibility thresholds and the first stages of the leave process. The broader planned FMLA overview explains the statute’s overall structure, while the planned guide to FMLA leave rights examines protected leave more broadly. Narrower planned pages address the FMLA hours test, baby-bonding leave, and FMLA and mental health conditions.
