FMLA Explained: Rules, Eligibility, and Your Rights to Leave

Last updated 13 hours ago. Our resources are updated regularly but please keep in mind that links, programs, policies, and contact information do change.

Under the Family and Medical Leave Act (FMLA), a worker can have a job to return to and still lose pay during the absence. The leave is generally unpaid, but the employer must maintain group health coverage during it, and the worker generally has a right to return to the same or an equivalent job when it ends.

Not every worker qualifies. Some states add pay: New York’s program, the example compared below, can replace some wages during leave that an employer covered by both laws may also count as FMLA leave. Before leave begins, the practical questions are what protects the job, what pays during the absence, and whether using one benefit also uses time available under another.

The protection starts with two coverage tests

The first test asks whether the employer is covered. A private employer is generally covered when it employs 50 or more people for 20 workweeks in the current or preceding calendar year. Public agencies and public or private elementary and secondary schools are covered regardless of their total number of employees.

The second test asks whether the employee is eligible. The usual rule requires enough service, hours and nearby co-workers: at least 12 months with the employer, at least 1,250 hours during the preceding 12 months, and at least 50 employees within 75 miles of the worksite. Both tests must be met. They count differently: the employer test asks how many people the employer employs, while the employee test asks how many it employs within 75 miles of the worker’s site.

Remote work does not erase the worksite test. For a teleworker, the home is not the FMLA worksite; the relevant place is generally the office where the employee reports or receives assignments. That can put a worker inside the 75-mile test even while working far from the office.

The reason for leave must fit the law

The Family and Medical Leave Act (FMLA) lets an eligible worker take up to 12 workweeks off in a 12-month period for a new child, to care for a spouse, child or parent with a serious health condition, or for a serious health condition that keeps the worker from doing their job.

The law also covers specified needs connected to military service. It is not a general bank of time for every difficult family event.

A serious health condition is not simply any illness that feels serious: the regulation that defines the term requires inpatient care or continuing treatment by a health care provider. The rule also recognizes periods when the condition, treatment or recovery prevents ordinary work or daily activity.

An ordinary cold, flu, upset stomach, non-migraine headache or routine dental problem usually does not meet that definition unless complications arise.

The law also limits which family members count. Labor Department guidance includes a spouse recognized where the marriage occurred, a biological, adoptive, step or foster parent, and a person who acted as a parent when the employee was a child. A parent-in-law is generally outside the federal definition.

For ordinary family-care leave, a child can be a biological, adopted, foster or stepchild, a legal ward, or a child for whom the employee acts as a parent. That parental role can mean day-to-day care or financial support, even without a biological or legal relationship. The child must be under 18, or, if 18 or older, unable to care for themselves because of a mental or physical disability when leave begins.

The employee does not need to diagnose the law during an emergency. A frightened caller needs to give enough facts for the employer to recognize a possible covered need, not recite the statute’s name.

Leave can come in pieces

For most qualifying needs, FMLA protects up to 12 workweeks of leave in a 12-month period. That 12 weeks is a total for one or more qualifying reasons. Time off for pregnancy complications, for example, can be counted against the same 12 weeks; it does not add 12 weeks on top.

The exception is military caregiver leave, for a worker whose family member is a current servicemember or recent veteran with a serious injury or illness: it can reach 26 workweeks in a single 12-month period. Whether the limit is 12 weeks or 26, the entitlement is measured by the employee’s normal workweek, not by one number of hours for everyone.

When medically necessary, leave may be taken intermittently or on a reduced schedule for treatment, recovery or care. Bonding leave after birth or placement generally needs the employer’s agreement before it can be split into smaller blocks.

An employer may count only the leave actually taken and generally must track it in the smallest increment it uses for other kinds of leave. A worker who needs periodic appointments does not automatically lose a whole day or week from the federal bank.

The gap between protected time and a paycheck

Federal FMLA leave is generally unpaid. Accrued vacation, sick time or other employer-provided paid leave may run at the same time as FMLA leave, either by the employee’s choice or under an employer policy. That arrangement supplies pay, but it does not create extra weeks beyond the protected period.

Group health insurance is different. During FMLA leave, the employer must maintain coverage on the same conditions that would have applied if the employee had kept working.

The National Partnership for Women & Families estimated that in 2025, about 11.3 million workers needed leave but did not take it, and that two-thirds said unpaid time was unaffordable. The estimate includes workers who were not eligible for FMLA, so it measures the broader need for leave rather than the performance of this statute alone.

Some states supply wage replacement or broader leave rights. The Labor Department identifies thirteen states and the District of Columbia with laws creating paid family and medical leave programs. State programs differ in wage replacement, available weeks and the service requirements for job protection. The Labor Department maintains a map linking to state agencies where workers can check rights and apply for benefits. Check the worker’s state program separately from federal FMLA coverage, because payment and job restoration may come from different laws.

Notice is a two-way process

A covered employer must display the Labor Department FMLA poster where employees and applicants can see it, even at a location with no eligible employees.

When leave is foreseeable, an employee generally must give at least 30 days’ notice. When that much warning is impossible, notice should come as soon as practical, often the same day or the next business day after the need becomes known.

The employer generally must send an eligibility notice within five business days after a leave request or learning that the reason may qualify. It must give written rights-and-responsibilities information with that notice, then designate qualifying leave within five business days after it has enough information, absent unusual circumstances. Designation, the formal decision that leave counts as FMLA leave, is the employer’s duty, not the employee’s.

An employer may request medical certification for a worker’s condition or covered family care. The certification may ask when the condition began, its expected duration, appropriate medical facts and how the need affects work or care. The worker generally has at least 15 calendar days to provide it. If it is incomplete, the employer must say in writing what is missing and allow at least seven calendar days to fix it. Certification is a request for those specific items, not permission to demand an entire medical history.

An employer’s leave policy can allow more time off than federal law protects. In 1996, an employee undergoing cancer treatment took 30 weeks of leave under her employer’s plan. The employer did not tell her that 12 weeks of the absence would count as FMLA leave. When she still could not return, the company terminated her employment. A Labor Department regulation then in force required 12 more weeks of leave because of the missing notice, but the Supreme Court held the regulation contrary to the law, and she was entitled to no more leave. Notice matters, but a notice error does not automatically create more leave.

Give enough information to show that the need may qualify, follow the employer’s usual procedure for reporting an absence when possible, and use the written rights-and-responsibilities notice to learn how the employer counts the leave year. The employee starts the conversation; the employer must ask for needed details and make the legal designation.

The return promise reaches beyond a job title

A worker who returns at the end of protected leave generally has a right to the same or an equivalent job. If the job is not the original one, an equivalent job must be virtually identical in pay, benefits and conditions, with substantially similar duties, authority, skill and responsibility. A familiar title does not make a materially worse schedule or role equivalent.

For leave based on the employee’s own condition, an employer may require a fitness-for-duty certification under a policy applied to similarly situated workers, if it gave advance notice. In it, the health care provider certifies that the employee is able to resume work. The employer may ask the health care provider to address the employee’s ability to perform essential functions, but only after giving the required notice and a list of those functions.

The restoration right is not absolute. An employee has no greater right to the job than continued work would provide, so a genuine layoff that would have included the employee can end the obligation.

A separate, narrow exception covers a salaried eligible worker among the highest-paid 10 percent within 75 miles when reinstatement would cause substantial and grievous economic injury to the employer. The employer must give written notice of that determination and its intention to deny restoration; it cannot deny the leave itself.

A denial is not always the final word

Federal law makes it unlawful to interfere with, restrain or deny FMLA rights. It also forbids discharge or discrimination against a person for opposing a practice the law prohibits.

A worker can contact the Labor Department’s Wage and Hour Division to ask questions or file a complaint. The division says complaints are confidential and that retaliation for filing or cooperating is prohibited. For a complaint, gather the company’s name and location, your contact details, and the circumstances of your leave request and the employer’s response.

A private lawsuit can seek employment, reinstatement, promotion and monetary relief, and a successful plaintiff may recover reasonable attorney and expert fees. A private FMLA lawsuit generally must be filed within two years after the last alleged violation, or within three years if the violation was willful.

Pay stubs and personal records of hours worked can also help. FMLA records can show leave dates and hours, written requests and notices, and disputes about whether time off was counted as protected leave.

Other laws can add more

Federal regulations expressly preserve state or local laws with greater leave rights. An employer may have to comply with both the federal and state systems, even though each government enforces its own law.

Federal workers also need to identify which system applies. The Office of Personnel Management (OPM) administers Title II of FMLA, which covers most civilian federal employees, while the Labor Department’s rules under Title I cover private-sector, state and local workers and some federal employees. The employing agency’s human resources office is the practical starting point for a federal worker.

An eligible federal employee may substitute up to 12 weeks of paid parental leave for unpaid FMLA leave after a birth, adoption or foster placement, using the same FMLA entitlement rather than adding another 12 weeks.

One law may preserve the job, another may replace part of the wage, and an employer policy may supply paid time that runs concurrently. Ask what each program pays, what it protects and whether using one reduces the time available under another. The comparison below uses New York as one example of a state paid-leave program; its figures are New York’s and do not describe other states’ programs.

How New York paid leave compares

New York Paid Family Leave may provide up to 12 weeks. Unlike federal FMLA, it cannot be used for the worker’s own serious health condition; New York has separate disability-benefits coverage. If the same event qualifies under both laws and the employer is covered by both, the employer may run the leaves together after notifying the worker that both apply and will be designated concurrently.

The argument over paid leave

Congress wrote the existing FMLA to balance workplace demands with family needs while accommodating employers’ legitimate interests. Its compromise is limited, unpaid leave with eligibility and documentation rules.

Paid-leave advocates argue that this balance leaves the right unusable for workers who cannot lose income. Their evidence is that millions of workers still report they could not afford unpaid leave, including some who are eligible for FMLA.

State programs are part of the argument too. At a House hearing on February 24, 2026, Adrienne Schweer of the Bipartisan Policy Center said women surveyed about having fewer children than they would like cite the cost of child care, fear of financial insecurity and lack of paid leave, and that state paid-leave programs are helping reduce that anxiety.

Employer advocates do not necessarily reject paid leave. At the same hearing, Greta Kessler, testifying on behalf of SHRM, the Society for Human Resource Management, cited SHRM research finding that 59 percent of employers considered coordinating FMLA with other leave at least somewhat difficult, while 28 percent reported uncertainty about coordinating it with other unpaid leave. She said those problems show the operational strain that leave complexity places on workforce planning and service continuity. Those are employers’ reported administrative experiences, not a finding that any particular paid-leave policy would fail.

FMLA can reserve time and a route back to work. It cannot, by itself, make every worker eligible or make the time affordable.
