The Family and Medical Leave Act (FMLA) can provide vital job-protected leave during significant family, medical, or military-related circumstances. However, FMLA eligibility requirements depend on both an employee’s work history and the employer’s size and location.
Before requesting leave, employees should understand whether their workplace is covered and whether they satisfy the applicable service requirements. Eligibility may also depend on the reason for leave, medical certification, and rules that vary under state law or employer policy.
Why FMLA Eligibility Requirements Matter Before Requesting Leave
FMLA eligibility requirements determine whether an employee may receive job-protected, unpaid leave under the federal Family and Medical Leave Act. Reviewing them before making a request helps employees understand whether the law applies to their employment situation.
Eligibility depends on several separate factors, including whether the employer is covered, how long the employee has worked for that employer, hours worked during the prior 12 months, and the number of employees near the worksite. A qualifying reason for leave is also required.
Understanding these requirements can prevent misunderstandings about leave rights, benefit continuation, return-to-work protections, and required documentation. It also allows employees to gather relevant records and communicate clearly with human resources when an unexpected medical, family, or military-related need arises.
An employee who does not meet federal FMLA eligibility requirements may still have protections under state leave laws, disability laws, employer policies, collective bargaining agreements, or other workplace benefit programs.
Employer Coverage Under the Family and Medical Leave Act
The FMLA applies only to covered employers, so employees should confirm employer status before relying on federal leave protections. Coverage is separate from an employee’s individual work-history eligibility.
Private-sector employers are generally covered when they employ 50 or more employees for at least 20 workweeks in the current or preceding calendar year. The 20 weeks need not be consecutive.
Public agencies—including federal, state, and local government employers—are covered regardless of workforce size. Public and private elementary and secondary schools are also covered, even when they employ fewer than 50 workers.
For many private-sector employees, FMLA eligibility requirements also depend on whether at least 50 employees work within 75 miles of the employee’s worksite. This geographic rule does not determine whether a public agency or school is covered.
Private-Sector Employers With 50 or More Employees
A private-sector employer is generally covered by the Family and Medical Leave Act when it employs 50 or more employees for at least 20 workweeks in the current or preceding calendar year. The 20 workweeks need not be consecutive.
For this employer-coverage test, employees on payroll are generally counted, including full-time, part-time, temporary, and jointly employed workers, subject to applicable FMLA counting rules. The law applies even if not all employees are eligible to take leave.
Meeting the 50-employee threshold is only one part of the FMLA eligibility requirements. An individual employee must also satisfy separate service, hours-worked, and worksite-distance standards before receiving FMLA-protected leave.
Employers that fall below the federal threshold may still be subject to state family and medical leave laws or may offer leave benefits through workplace policies.
Public Agencies and Elementary or Secondary Schools
Public agencies are covered employers under the Family and Medical Leave Act regardless of the number of people they employ. This includes federal, state, and local government agencies, such as departments, municipalities, and public libraries.
Public and private elementary and secondary schools are also covered regardless of workforce size. A small private school may therefore be subject to FMLA obligations even when it has fewer than 50 employees.
Coverage of the employer does not automatically establish an individual worker’s right to leave. Employees generally must still satisfy the applicable FMLA eligibility requirements, including required length of service and hours worked.
The special coverage rule for public agencies and schools means the 50-employee threshold does not determine whether the employer is covered. The 75-mile employee-count rule may still affect whether an employee meets the individual eligibility standard.
The 75-Mile Employee Count Rule
For a private-sector employer to be covered by the FMLA, it generally must employ 50 or more employees for at least 20 workweeks in the current or preceding calendar year. An employee must also satisfy a separate local workforce test.
The employee must work at a location where the employer has at least 50 employees within 75 miles. The 75-mile distance is measured by surface miles, using the shortest available public route rather than straight-line distance.
Employees at the worker’s own site and at other worksites within that radius may be counted. For remote employees, the relevant worksite is usually the office or location from which they receive assignments or report, not their home.
This rule can affect FMLA eligibility requirements for employees at small or isolated locations, even when the employer has far more than 50 employees nationwide.
Employee Work History Requirements for FMLA Leave
To qualify for FMLA leave, an employee generally must have worked for the covered employer for at least 12 months. These months do not need to be consecutive, and prior employment may count in certain circumstances.
The employee must also have completed at least 1,250 hours of service during the 12 months immediately before the leave begins. Only hours actually worked are counted; paid vacation, holidays, and other paid leave usually do not count.
For most private-sector employees, FMLA eligibility requirements also depend on working at a location where the employer has at least 50 employees within 75 miles. This worksite standard is separate from the 12-month and 1,250-hour requirements.
Employers may use payroll records and timekeeping data to assess hours worked. Employees with variable schedules, recent transfers, or breaks in service may need to review their records carefully when determining whether they meet the applicable requirements.
Qualifying Reasons for FMLA Leave
Eligible employees may take up to 12 workweeks of FMLA leave in a 12-month period for the birth of a child, bonding after adoption, or placement of a child for foster care. Bonding leave generally must be used within one year of the event.
Leave may also be available when the employee cannot perform essential job functions because of a serious health condition. An employee may use intermittent or reduced-schedule leave when medically necessary and properly supported.
FMLA eligibility requirements also permit leave to care for a spouse, child, or parent with a serious health condition. The Act does not generally cover care for grandparents, siblings, in-laws, or unmarried domestic partners, subject to limited in loco parentis situations.
Military family provisions include qualifying exigency leave related to a covered service member’s deployment. Military caregiver leave may provide up to 26 workweeks in a single 12-month period to care for a covered service member or certain veterans with a qualifying serious injury or illness.
Birth, Adoption, or Foster Care Placement
Eligible employees may take up to 12 workweeks of FMLA leave during a 12-month period for the birth of a child, prenatal care, recovery from childbirth, and bonding with a newborn. Both parents may qualify, subject to applicable employer rules.
Leave is also available when a child is placed with an employee for adoption or foster care. Covered purposes include time needed for placement, related appointments, meetings with agencies or attorneys, and bonding after the child joins the household.
- Bonding leave must generally be taken within 12 months of birth or placement.
- Leave may be used before adoption or foster placement when necessary for the process.
- Intermittent bonding leave requires employer approval, unless leave is medically necessary.
Under FMLA eligibility requirements, spouses employed by the same covered employer may be limited to a combined 12 weeks of leave for birth, adoption, foster care placement, or bonding. This limitation does not generally apply to leave for an employee’s own serious health condition.
An Employee’s Own Serious Health Condition
An eligible employee may take FMLA leave when a serious health condition makes the employee unable to perform the functions of their position. Leave may be taken continuously, intermittently, or through a reduced work schedule when medically necessary.
A serious health condition generally involves inpatient care or continuing treatment by a health care provider. It can include conditions requiring an overnight hospital stay, multiple treatments, extended incapacity, pregnancy-related incapacity, or chronic illnesses such as asthma, diabetes, or epilepsy.
Minor ailments, including common colds, routine flu cases, earaches, and cosmetic treatments, ordinarily do not qualify unless complications create a condition meeting the legal standard. The condition must result in an inability to work or require qualifying treatment.
Under FMLA eligibility requirements, an employer may request medical certification supporting the need for leave. The certification should confirm the condition, the expected duration of incapacity, and whether intermittent leave or reduced scheduling is medically necessary.
Caring for a Family Member With a Serious Health Condition
Eligible employees may take up to 12 workweeks of unpaid, job-protected FMLA leave in a 12-month period to care for a spouse, child, or parent with a serious health condition. The employee must provide needed physical or psychological care.
Care may include transporting the family member to medical appointments, arranging changes in care, helping with daily needs, or providing comfort and reassurance during treatment or recovery. The family member does not have to live with the employee.
Under federal FMLA rules, the term does not generally include care for grandparents, siblings, parents-in-law, or unmarried partners. A person who stood in loco parentis to the employee may qualify as a parent, depending on the facts.
FMLA eligibility requirements still apply, including the employee’s work-history requirements and the employer’s coverage status. An employer may request medical certification confirming the family member’s serious health condition and the employee’s need to provide care.
Military Family Leave and Military Caregiver Leave
Eligible employees may take up to 12 workweeks of FMLA leave in a 12-month period for a qualifying exigency related to a covered military member’s deployment or call to covered active duty.
Qualifying exigencies may include:
- Addressing short-notice deployment matters;
- Attending military events, briefings, or counseling;
- Arranging childcare, school, financial, or legal matters; and
- Spending time with a service member on rest and recuperation leave.
Military caregiver leave provides up to 26 workweeks of leave during a single 12-month period to care for a covered servicemember or qualifying veteran with a serious injury or illness. The employee must be the servicemember’s spouse, child, parent, or next of kin.
These provisions operate within the broader FMLA eligibility requirements, including employer coverage, 12 months of employment, 1,250 hours worked during the preceding 12 months, and the applicable 75-mile worksite rule.
Understanding the Serious Health Condition Standard
A serious health condition under the FMLA generally involves an illness, injury, impairment, or physical or mental condition requiring inpatient care or continuing treatment by a health care provider. Not every illness or medical appointment qualifies.
Continuing treatment may include:
- Incapacity lasting more than three consecutive full calendar days with qualifying treatment;
- Chronic conditions requiring periodic treatment, such as asthma or diabetes;
- Pregnancy-related conditions or prenatal care; or
- Permanent or long-term conditions for which treatment may be ineffective.
Short-term conditions such as common colds, minor headaches, routine dental issues, and ordinary stomachaches generally do not meet the standard unless complications arise. The facts of each condition, including treatment and inability to work, determine whether leave is protected.
For FMLA eligibility requirements, employers may request medical certification supporting the need for leave. The certification should establish the condition’s qualifying nature and anticipated duration, without requiring a diagnosis in every case.
Determining Whether a Worksite Meets the 75-Mile Requirement
For FMLA eligibility requirements, an employee must work at a site where the employer has at least 50 employees within 75 miles. This rule applies to the employee’s assigned worksite, not necessarily the employer’s headquarters.
The distance is generally measured by surface miles using the shortest route over public streets, highways, and waterways. Straight-line or “as-the-crow-flies” distance is not the governing measurement.
Employers should count employees whose work locations fall within that radius, including:
- Full-time and part-time employees;
- Employees on payroll, even if temporarily absent; and
- Remote employees assigned to a particular office or worksite.
For remote or mobile employees, the relevant worksite may be the office to which they report, receive assignments, or are administratively assigned. Employees may request confirmation of the designated worksite and nearby employee count when evaluating FMLA eligibility requirements.
Documentation and Certification That May Affect Eligibility
Employers may request supporting information after an employee seeks leave, and incomplete or late documentation can delay FMLA designation. Meeting the basic FMLA eligibility requirements does not eliminate the need to provide requested certification.
For leave related to a serious health condition, an employer may require medical certification from a health care provider. The certification generally confirms the condition, the need for leave, and the expected duration, without requiring a diagnosis.
Within five business days of a leave request or learning that leave may qualify, the employer generally must provide an eligibility notice and a rights-and-responsibilities notice. These documents explain whether the employee appears eligible and identify required information.
Employees usually have at least 15 calendar days to return a requested certification. If information is incomplete or insufficient, the employer must identify the deficiency and generally allow seven calendar days to correct it.
Medical Certification for Health-Related Leave
An employer may require medical certification when leave is requested for an employee’s serious health condition or to care for a covered family member. The certification must be completed by an appropriate health care provider and contain sufficient medical facts to support the need for leave.
Employers generally must allow at least 15 calendar days for an employee to provide a requested certification, unless it is not practicable despite diligent, good-faith efforts. Employees need not disclose a diagnosis if the certification otherwise provides the required information.
A complete certification may address the condition’s likely duration, necessary treatment, periods of incapacity, and whether intermittent or reduced-schedule leave is medically necessary. These details help an employer evaluate whether the request meets FMLA eligibility requirements.
If certification is incomplete or insufficient, the employer must identify the deficiency in writing and provide at least seven calendar days to cure it, absent impracticability. An employer may also seek authentication or clarification through permitted channels, without directly contacting the employee’s provider through the employee’s supervisor.
Employer Eligibility and Rights-and-Responsibilities Notices
When an employer learns that leave may qualify under the FMLA, it generally must provide an eligibility notice within five business days, absent extenuating circumstances. The notice states whether the employee meets the basic FMLA eligibility requirements.
If the employee is eligible, the employer must also provide a rights-and-responsibilities notice. This document explains key obligations, including:
- Whether medical certification is required
- The deadline for submitting requested certification
- Whether accrued paid leave must be used concurrently
- Employee benefit and job-restoration rights
If the employee is not eligible, the employer must state at least one reason, such as insufficient months of service, hours worked, or an ineligible worksite. Employers may use the U.S. Department of Labor’s optional Form WH-381.
These notices do not guarantee that the requested leave will be approved. They clarify eligibility and procedural requirements while the employer evaluates whether the stated reason qualifies for FMLA protection.
Deadlines for Providing Requested Information
When an employer requests medical certification or other supporting information, employees generally have 15 calendar days to provide it. If meeting that deadline is not practicable despite diligent, good-faith efforts, additional time may be appropriate.
Employers must give employees at least seven calendar days to cure an incomplete or insufficient medical certification, unless seven days is not practicable under the circumstances. A certification is insufficient when it is vague, ambiguous, or nonresponsive.
Failure to return requested information within the stated timeframe may allow an employer to delay or deny FMLA leave. These deadlines can directly affect whether an employee satisfies FMLA eligibility requirements and receives job-protected leave.
Employees should keep copies of submitted forms and promptly communicate any difficulty obtaining records from a health care provider. Employers may request clarification or authentication of a certification, subject to FMLA confidentiality and contact restrictions.
State Family Leave Laws and More Generous Employer Policies
Federal FMLA establishes a nationwide baseline, but several states provide family and medical leave protections that are broader than federal law. State laws may cover smaller employers, require less employee service, allow different qualifying reasons, or provide paid leave benefits.
For example, California, New York, New Jersey, Washington, Massachusetts, and several other states administer paid family and medical leave programs. Eligibility rules, benefit amounts, covered family members, and application procedures vary by jurisdiction.
Employees should review both federal FMLA eligibility requirements and the laws of the state where they work. When federal and state protections apply to the same absence, leave may run concurrently, though the law offering greater employee protection generally controls.
Employers may also voluntarily offer leave policies exceeding legal minimums, such as paid parental leave, broader definitions of family, or coverage for employees who do not qualify for FMLA leave. Written policies and human resources guidance help clarify available benefits.
Steps Employees Can Take to Confirm FMLA Eligibility
Employees should begin by asking Human Resources whether the organization is a covered employer and whether their assigned worksite has at least 50 employees within 75 miles. Public agencies and most schools are covered regardless of employee count.
They should review payroll and employment records to confirm at least 12 months of employment and 1,250 hours worked during the 12 months before leave begins. Paid time off generally does not count toward the 1,250-hour threshold.
Employees should identify the reason for leave and determine whether it involves a qualifying event, such as a serious health condition, childbirth, adoption, foster care placement, or a covered military-related need. Relevant medical or military documentation may be required.
A written leave request should be submitted as soon as practicable, following the employer’s usual notice procedures. Employees can request the employer’s eligibility notice and review any certification forms or deadlines that affect FMLA eligibility requirements.
