FMLA Leave Basics: Eligibility, Notice, Job Protection, and Where State Laws Add More

Updated October 21, 2026 · By the VeriAdvisor editors

A new baby, a parent's surgery, or your own serious illness can force you away from work for weeks. The federal Family and Medical Leave Act (FMLA) gives many workers the right to take that time without losing their jobs. It does not guarantee a paycheck, and a large share of workers do not qualify because of employer size or hours worked. This guide explains who is covered, how much leave you can take, what notice and paperwork are usually involved, and how some state programs go further. It is general information, not legal advice; for a specific situation, consult a licensed employment attorney, your state labor agency, or the U.S. Department of Labor's Wage and Hour Division.

What the FMLA gives you

The FMLA is a federal law enforced by the Department of Labor. Eligible employees may take up to 12 workweeks of unpaid, job-protected leave in a 12-month period for specified reasons, and up to 26 workweeks in a single 12-month period to care for a covered service member with a serious injury or illness. According to the Department's Fact Sheet #28, the qualifying reasons are:

• The birth of a child and bonding with the newborn, or placement of a child for adoption or foster care.
• Caring for a spouse, child, or parent with a serious health condition.
• Your own serious health condition that makes you unable to do your job.
• Certain qualifying military family reasons, including a qualifying exigency and military caregiver leave.

While you are on leave, the employer must continue your group health coverage on the same terms as if you were still working, and when you return you must be restored to the same or a virtually identical position. The leave is unpaid, although you may choose, or your employer may require, to use accrued paid leave at the same time depending on the policy; see our tool on PTO rules for how accrued time is treated elsewhere.

Are you eligible?

You must meet every one of these tests. The Department of Labor lists them as follows: you have worked for a covered employer for at least 12 months; you have at least 1,250 hours of service in the 12 months before the leave starts; and you work at a location where the employer has at least 50 employees within 75 miles. Covered employers are private employers with 50 or more employees, plus public agencies and schools of any size.

The numbers produce some surprising results. An employee who works 24 hours a week gets about 1,248 hours in a year, just short of the 1,250-hour requirement. A worker at a small branch of a large company may fail the 50-within-75-miles test even though the company has thousands of employees overall. And the 12 months of employment do not have to be consecutive. Our FMLA eligibility calculator lets you test your own hours.

What counts as a "serious health condition"

The regulations define it as an illness, injury, impairment, or physical or mental condition involving inpatient care or continuing treatment by a health care provider. Typical examples include pregnancy and prenatal care, chronic conditions that cause periodic incapacity (such as asthma, diabetes, or epilepsy), conditions requiring multiple treatments, and incapacity of more than three consecutive days with ongoing treatment. A cold or routine dental visit normally does not qualify. Mental health conditions can qualify when they meet the same tests. You can take leave all at once, or in some cases intermittently or on a reduced schedule when medically necessary, which is common for chemotherapy or recurring flare-ups. The rules for intermittent leave and planned treatment are in the regulations at 29 CFR Part 825.

Notice and paperwork

When you need leave, give your employer notice as soon as possible and practical. Under the regulations, when the need is foreseeable (a planned surgery or expected birth), the standard is 30 days' notice or as soon as practicable if that is not possible. For emergencies, tell the employer as soon as you reasonably can; you do not need to say the word "FMLA," but you must give enough information for the employer to realize the leave may be covered.

The employer then has its own duties. It must tell you whether you are eligible and explain your rights and responsibilities, generally within five business days of learning that the leave may qualify. It may ask for a medical certification from your or your family member's health care provider; the Department of Labor says the employer must allow at least 15 calendar days for you to provide the information. The Department publishes optional forms for the certification. Keep copies of everything, and send documents in a way that leaves a record, such as email or a patient portal message. A missed deadline can delay or jeopardize protection unless there is a good reason.

Employers may require you to use accrued paid leave at the same time as FMLA leave if their policy says so. They cannot force you to use leave you do not have, and they cannot count FMLA absences against you under an attendance policy.

Example: counting the 12 weeks

Suppose an employee works a Monday-to-Friday schedule and takes continuous leave to recover from surgery. The entitlement is 12 workweeks, which is 12 x 5 = 60 scheduled workdays, or 480 hours for an 8-hour day. If the same employee later needs intermittent leave of 4 hours for each of 20 medical appointments, that uses 80 hours, or two workweeks of the 12. These are illustrative numbers. The employer chooses how to measure the 12-month period (for example, a calendar year, a fixed fiscal year, or a rolling backward period), and it should tell you which method it uses.

Your protections

• Job restoration. You are entitled to the same or an equivalent position with equivalent pay, benefits, and working conditions. An exception allows an employer to deny restoration to a "key employee," generally among the highest-paid 10 percent of employees, when restoration would cause substantial and grievous economic injury, but the employer must follow a specific notice process.
• No interference or retaliation. It is unlawful to interfere with your FMLA rights or to fire or discipline you for taking protected leave. Keep a record of what happened; the workplace retaliation timeline builder helps.
• Health insurance. Coverage continues on the same terms; you may still owe your normal share of premiums.
• No loss of accrued benefits. Benefits earned before leave are not lost, although you do not necessarily keep earning new ones during unpaid leave.

Layoffs unrelated to your leave can lawfully happen during leave, but the employer has the burden of showing you would have been laid off anyway.

When the FMLA does not apply: state programs

Because many workers fall outside the FMLA, states have created their own programs. The details vary widely, and some provide wage replacement, which the federal law does not.

If more than one law covers your leave, the more generous one usually applies, and periods can often run at the same time. Ask your employer or the state agency how your leave will be counted.

If something goes wrong

1. Ask your employer in writing to confirm your leave status and your return date.
2. If you are denied leave or retaliated against, document dates, names, and what was said.
3. File a complaint with the Department of Labor's Wage and Hour Division, which you can do by phone or online at no cost, or consult an attorney. You may also sue; the general limitations period is two years, extended to three for willful violations (29 U.S.C. 2617(c)). Learn why such deadlines matter in our statute of limitations guide.
4. For state-law claims, check the state agency's deadlines, which can be shorter. The filing deadline calculator helps you plan.
5. If you are owed wages as well, see final paycheck laws.

Practical tips

• Talk to HR early, even informally. Many problems come from missing the employer's own call-in rules for absences.
• Ask your health care provider to complete the certification promptly and to state the expected duration and any need for intermittent leave.
• Confirm in writing how your benefits, pay raises, and bonuses will be handled during leave.
• Do not assume you are protected just because you are sick; confirm you meet the eligibility tests or a state equivalent.
• Plan finances: unpaid leave is unpaid unless a state program or your employer's policy pays you.

This overview is general information and cannot account for your employer's policy, a union contract, or recent changes. Rules are updated periodically, so verify current requirements with the Department of Labor and your state agency, and speak with a licensed attorney or legal aid office if you believe your rights were violated.
