To apply for FMLA, you tell your employer you need leave for a reason the law covers, follow its usual request process, and return any medical certification it asks for, usually within 15 calendar days. There’s no single government application: the Family and Medical Leave Act (FMLA) process runs through your employer, its HR team, or a leave administrator. If you’re dealing with a health problem or caring for a family member, knowing each step and deadline can help you avoid delays and protect your job.
Key takeaways
- More than half of U.S. employees are eligible for FMLA, which provides up to 12 weeks of unpaid, job-protected leave a year.
- After you ask for leave, your employer generally has 5 business days to tell you if you’re eligible, and you generally have at least 15 calendar days to return medical certification.
- Give notice as early as you can and keep copies of everything, since late or incomplete paperwork can delay approval.
What does it mean to apply for FMLA?
Applying for FMLA means formally requesting job-protected leave from your employer. You don’t file with the government, and you don’t need to use the word “FMLA” the first time you ask.
FMLA is often confused with related benefits, so it helps to know what you’re applying for:
- FMLA leave protects your job and health coverage but is unpaid.
- Short-term disability may replace part of your income but doesn’t, by itself, protect your job.
- State paid leave programs, where they exist, are separate applications to the state or an insurer.
- Paid time off (PTO) from your employer may be used during FMLA, depending on its policy.
Because FMLA provides job-protected leave but doesn’t replace income, many people apply for FMLA and a wage-replacement benefit at the same time. Our guide to FMLA and short-term disability explains how they work together.
Who can apply for FMLA?
You can apply if you work for a covered employer and meet the eligibility rules. Under federal rules, you’re generally eligible if you:
- Work for a covered employer, such as a private employer with 50 or more employees, or any public agency or school.
- Have worked there at least 12 months, which don’t need to be consecutive.
- Worked at least 1,250 hours in the 12 months before your leave.
- Work at a location where your employer has at least 50 employees within 75 miles.
A national survey of U.S. workers and worksites found that 56% of employees are eligible for FMLA. Your HR department or leave administrator can confirm whether you qualify.
You can use FMLA for your own serious health condition, to care for a spouse, child, or parent with a serious health condition, for the birth or placement of a child, or for certain military family needs. In the same survey, 51% of FMLA-qualifying leaves were for the employee’s own serious health condition.
How to apply for FMLA, step by step
How long it takes depends mostly on how quickly paperwork moves between you, your provider, and your employer. Here’s how the process typically works.
Step 1: Tell your employer you need leave
For leave you can plan ahead, such as a scheduled surgery or a due date, give at least 30 days’ notice when possible. For unexpected leave, give notice as soon as it’s practical, generally within your employer’s usual call-in rules.
When you ask, include:
- That you need time off and when you expect it to start
- The general reason, such as a health condition that keeps you from working or caring for a parent
- How long you expect to be out, or that you’ll need time off in separate blocks (intermittent leave)
You don’t have to share your diagnosis with your manager. A vague reason like “I’m sick” may not be enough, though, so give enough detail for your employer to see that the leave may qualify.
Step 2: Follow your employer’s leave procedures
Use your employer’s normal process, such as an HR portal, a leave form, or a call to a third-party leave administrator. In an emergency, someone else can contact your employer for you.
Step 3: Watch for your eligibility notice
Your employer must tell you within 5 business days whether you’re eligible for FMLA. It must also give you a written notice of your rights and responsibilities, often on Form WH-381, which explains whether you need to provide certification and whether you must use paid leave.
Step 4: Get medical certification
Your employer may ask for medical certification from a health care provider. You generally have at least 15 calendar days to return it. The official FMLA forms include WH-380-E for your own condition and WH-380-F for a family member’s, though some employers use their own versions.
Our guide to FMLA forms and how to complete them walks through each section. If your own doctor can’t complete your paperwork before the deadline, a board-certified physician can evaluate you for FMLA certification in a secure video visit. When you book, choose the state where you’ll be physically located at the time of the visit.
Step 5: Fix any gaps quickly
If your employer finds the certification incomplete or unclear, it must tell you in writing what’s missing. You then generally have 7 calendar days to fix it. HR or a leave administrator may contact your provider to clarify the form, but your direct supervisor may not.
Step 6: Receive your designation notice
Once your employer has enough information, it must give you a written designation notice within 5 business days, often on Form WH-382. This notice confirms whether your leave counts as FMLA and how much of your 12 weeks it will use.
What happens after you apply?
Once your leave is approved, your job and group health coverage are protected while you’re out. When you return, you’re entitled to the same job or an equivalent one with the same pay and benefits.
A few things can come up during leave:
- Paid leave: Your employer may let you, or require you to, use paid time off during FMLA.
- Second opinions: If your employer doubts a complete certification, it may require a second opinion at its own expense.
- Recertification: For ongoing conditions, your employer may ask you to recertify, generally no more often than every 30 days and only in connection with an absence, though it can ask every 6 months in any case.
- Status updates: Your employer may ask for periodic updates on when you plan to return.
If you need leave in separate blocks of time, our guide to intermittent FMLA explains how your provider estimates how often and how long you’ll be out.
Common mistakes that delay FMLA approval
Many delays come from timing and paperwork problems. Watch for these:
- Waiting too long to give notice. Late notice without a good reason can delay your FMLA coverage.
- Giving too little detail. Your employer needs enough information to recognize that the leave may qualify.
- Missing the certification deadline. Late certification can leave some absences unprotected until it’s complete.
- Vague frequency and duration. Certifications for intermittent leave need realistic estimates of how often and how long you’ll be out.
- Not keeping copies. Save every form, email, and notice in case questions come up later.
For people with chronic conditions, getting a provider to complete paperwork can be its own hurdle. Our article on navigating the FMLA maze covers common barriers and how to work around them.
What if your FMLA request is denied?
Start by asking HR for the reason in writing, since many denials come from missing paperwork or eligibility questions you can fix. If you believe your rights were violated, you can contact the Wage and Hour Division at 1-866-487-9243 to file a complaint, or bring a private lawsuit.
Federal regulations set the deadline for a lawsuit at 2 years after the last violation, or 3 years if it was willful. For advice about your specific situation, consider speaking with an employment attorney.
When to seek medical attention
FMLA paperwork can wait, but your health shouldn’t. Contact a health care provider if your symptoms are getting worse, a new symptom appears, or you’re not recovering as expected.
This is not an emergency service. If you have chest pain, trouble breathing, signs of a stroke, or another emergency, call 911 or go to the nearest emergency room. If you’re having thoughts of suicide or are in crisis, call or text 988 to reach the Suicide & Crisis Lifeline.
Frequently asked questions
How long does it take to get FMLA approved?
It depends on how quickly paperwork moves. Your employer generally has 5 business days to confirm eligibility, you have at least 15 calendar days to return certification, and your employer then has 5 business days to designate the leave once it has enough information.
Can I apply for FMLA after my leave has started?
Often, yes. For unexpected leave, such as a sudden illness or hospital stay, you need to give notice as soon as it’s practical, and someone else can contact your employer for you in an emergency.
Do I have to tell my employer my diagnosis?
No. You need to share enough for your employer to recognize that the leave may qualify, but you don’t have to disclose a specific diagnosis to your manager. Your provider’s certification includes medical facts about the condition.
Can I apply for FMLA for mental health?
Yes, if your condition is a serious health condition, such as one that needs ongoing treatment or causes periods when you can’t work. Our guide to taking FMLA for mental health explains what certification looks like.
Who decides whether my FMLA is approved?
Your employer or its leave administrator decides whether your leave qualifies and designates it as FMLA. Medical certification supports your request, but it does not guarantee approval.
