How to Get FMLA Leave: Notice, Certification, and Job Return

To get FMLA leave, you need to confirm you’re eligible, notify your employer that you need time off for a covered reason, and return a medical certification within 15 days so your employer can formally designate the absence as protected. Here is how to get FMLA leave step by step, from checking whether you qualify to walking back through the door when your leave ends.

Confirm You Qualify

Two things have to be true before FMLA applies: your employer has to be covered, and you personally have to be eligible.

Private employers are covered only if they have 50 or more employees on the payroll for at least 20 workweeks in the current or prior year. Public agencies and public schools are covered no matter how many people they employ.¹

Even at a covered employer, you have to meet three tests:

You’ve worked for the employer at least 12 months. Those months don’t need to be consecutive, but a break of more than seven years generally erases earlier service unless you left for military duty or had a written rehire agreement.²
You’ve logged at least 1,250 hours of actual work in the 12 months right before your leave starts. Paid vacation, sick days, and holidays don’t count toward the 1,250.²
Your employer has at least 50 employees working within 75 miles of your worksite. This is the requirement that catches people at companies with scattered small offices.²

The 50-in-75 count is taken at the moment you give notice of your need for leave. Once you’re eligible at that point, later drops in headcount don’t undo it. If you fail any of the three tests, your employer has no federal obligation to grant FMLA-protected leave, though your state may have its own family or medical leave law with different rules worth checking.

Confirm Your Reason Is Covered

FMLA recognizes a specific list of reasons, and up to 12 weeks of leave are available in a 12-month period for any of them:³

Bonding with a newborn, or with a child newly placed for adoption or foster care. This leave has to be taken within 12 months of the birth or placement.
Caring for a spouse, child, or parent with a serious health condition. Siblings, grandparents, and in-laws are not covered unless they raised you in a parental role.
Your own serious health condition that keeps you from performing the essential functions of your job.
A qualifying exigency arising from a spouse, child, or parent’s deployment to a foreign country, such as arranging childcare, attending military events, or handling deployment-related financial or legal matters.⁴
Caring for a covered servicemember with a serious injury or illness, if you’re their spouse, child, parent, or next of kin. This category comes with an expanded entitlement of up to 26 weeks in a single 12-month period.³

What Counts as a Serious Health Condition

A serious health condition is one that involves either inpatient care (an overnight stay in a hospital or hospice) or continuing treatment by a healthcare provider. Continuing treatment covers a few situations: conditions that leave you unable to work for more than three consecutive days and require ongoing care, chronic conditions with periodic flare-ups like asthma or diabetes, pregnancy-related incapacity, and permanent or long-term conditions such as terminal illness or Alzheimer’s.⁵

The bar is higher than many people expect. Colds, the flu, earaches, stomach bugs, and routine dental problems generally don’t qualify unless complications develop. Mental health conditions and severe allergies can qualify, but they have to meet the same incapacity and treatment thresholds. Most denied claims fail here: the illness is real, but the medical certification doesn’t document enough incapacity or ongoing treatment.

Who Counts as a Child or Parent

FMLA’s definition of “child” reaches beyond biology. It includes adopted children, stepchildren, foster children, legal wards, and any child you’re raising in a parental role even without a legal or biological tie. Grandparents, aunts, or older siblings actively raising a child can qualify as parental figures, and the fact that biological parents are also in the picture doesn’t automatically disqualify someone else.⁶

Give Your Employer Notice

When you know about your need for leave in advance, notify your employer at least 30 days ahead. This applies to due dates, scheduled surgeries, and planned adoption placements.⁷ When 30 days isn’t possible, such as a sudden hospitalization, notify your employer as soon as you reasonably can, which usually means the same day or the next business day after you learn of the need.

You don’t have to use the phrase “FMLA leave.” You do have to give enough information that your employer can see the reason might qualify. “I need to be out for surgery next month” or “my father was just admitted and I need to be with him” is enough to trigger your employer’s obligation to evaluate eligibility. Something vague like “I need personal time” is not.

Return the Medical Certification

Your employer will almost always ask for medical documentation. The standard Department of Labor forms are WH-380-E for your own condition and WH-380-F when you’re caring for a family member. Your healthcare provider fills out the medical portions, certifying when the leave will start, how long it’s expected to last, and whether it needs to be intermittent or continuous. The provider doesn’t have to disclose your specific diagnosis to your employer.

Once your employer requests certification, you have 15 calendar days to get it completed and returned. Missing that deadline can delay or jeopardize your protected leave, so schedule the appointment early and follow up rather than waiting on the doctor’s office. If the certification comes back incomplete or unclear, your employer must tell you in writing exactly what’s missing, and you get another seven calendar days to fix it.⁸

What Your Employer Must Send Back

Two formal notices come back to you on strict timelines.

Within five business days of learning your absence may qualify, your employer must give you an eligibility notice saying whether you meet the FMLA requirements. If you’re not eligible, the notice has to say which requirement you missed. Along with it comes a rights and responsibilities notice explaining what you have to do next, including certification and whether you’ll need a fitness-for-duty clearance to return.⁹

After receiving your certification, your employer has another five business days to send a designation notice. That notice confirms whether the leave officially counts as FMLA, how much time will be deducted from your 12-week entitlement, and whether you’re required to use paid leave concurrently.⁹ Once you have the designation notice, your absence is protected.

Getting Paid During Leave

FMLA protects your job, not your paycheck. The leave itself is unpaid under federal law.¹⁰ You can use accrued paid time off, vacation, or sick leave concurrently with FMLA if your reason fits within the employer’s paid leave policy, and your employer can require you to burn through that paid balance before you shift to unpaid status.

Some states run mandatory paid family and medical leave programs that provide partial wage replacement. When you’re collecting state benefits, your employer generally can’t force you to also drain your accrued PTO on top of those benefits, though you can choose to supplement voluntarily to get closer to full pay. The financial picture changes considerably in states with these programs, so it’s worth checking whether yours has one before assuming you’ll be without income.

If Your Certification Is Challenged

If your employer doubts your certification, they can require a second opinion from a different healthcare provider at their expense. They pick the doctor, but it can’t be someone who regularly works for the company, and you keep provisional FMLA protections, including health insurance, while the second opinion is pending.¹¹

If the second opinion conflicts with your first, the employer can pay for a third opinion from a provider you and the employer choose together. The third opinion is final and binding on both sides. Your employer must also reimburse reasonable travel costs for either exam and generally can’t send you outside your normal commuting area.

Taking Leave Intermittently

FMLA leave doesn’t have to come in one continuous block. If your condition requires periodic treatment or unpredictable flare-ups, you can take leave in smaller pieces: leaving early for appointments, missing individual days, or working a reduced schedule for weeks at a time. When intermittent leave is tied to planned treatment, try to schedule it so it disrupts your employer’s operations as little as possible.

Employers track intermittent leave in increments no larger than one hour. If your workplace tracks other leave in 15-minute blocks, they can use that smaller increment for FMLA, but never a larger one.¹² You can’t be charged FMLA time for any period you actually worked, so a two-hour early departure costs you two hours of your bank, not a full day.

Coming Back to Work

When your leave ends, you’re entitled to return to the same job or an equivalent one with matching pay, benefits, shift, location, duties, and working conditions. Same title isn’t enough on its own if the substance changes. Your group health coverage must have stayed active throughout leave under the same conditions as if you’d kept working.¹³

If you took leave for your own serious health condition, your employer can require a fitness-for-duty certification before you return, but only under a policy applied uniformly to similarly situated employees. If the employer wants your provider to confirm you can perform the essential functions of the job, they must give you a list of those functions no later than the designation notice.¹⁴ You pay for the fitness-for-duty exam, and your employer cannot get a second or third opinion on it.

One narrow situation lets an employer deny reinstatement: the “key employee” exception, which applies to salaried employees in the top 10 percent of pay within 75 miles of the worksite when restoring the position would cause substantial and grievous economic injury to the organization.¹³ The standard is intentionally hard to meet and rarely comes up outside senior executive situations, and the employer forfeits the exception if they don’t give the required written notices at the time you request leave.

If Your Employer Interferes or Retaliates

Federal law makes it illegal for your employer to interfere with your FMLA rights or punish you for using them.¹⁵ Retaliation goes beyond outright firing. The Department of Labor treats each of the following as prohibited: discouraging you from taking leave, using FMLA absences against you in reviews or promotion decisions, manipulating your schedule to undercut your eligibility, and counting protected absences under a no-fault attendance policy.¹⁶ Protection also extends to anyone who files a complaint, cooperates with an investigation, or testifies in an FMLA proceeding.

You have two ways to push back. You can file a confidential complaint with the Department of Labor’s Wage and Hour Division by calling 1-866-487-9243 or going through their website.¹⁷ You can also file a private lawsuit within two years of the last violation, or three years if it was willful. A successful case can recover lost wages and benefits, an equal amount in liquidated damages unless the employer proves good faith, attorney’s fees, and orders such as reinstatement.¹⁸ Emotional distress and punitive damages aren’t available under FMLA itself, though some state leave laws allow them.
