How Long Can a Leave of Absence Be?

The duration depends on the type of leave and the applicable law. Under the FMLA, eligible employees at covered employers are generally entitled to up to 12 weeks of unpaid, job-protected leave per year for qualifying reasons. Military caregiving leave under FMLA can extend up to 26 weeks in a single 12-month period. Some states have enacted their own paid family and medical leave laws that provide additional weeks of leave or wage replacement benefits — check your state's department of labor for specifics. For personal leaves that fall outside a legally protected category, the duration is typically a matter of agreement between the employee and employer. There is no federal requirement that employers grant personal leaves of any specific length. The bottom line: A leave of absence can last anywhere from a few weeks to several months, depending on the reason, the applicable law, and your employer's policy. Always discuss duration with your HR department before submitting your request.

What Is the Difference Between a Leave of Absence Letter and a Resignation Letter?

These two documents serve entirely different — and nearly opposite — purposes. A leave of absence letter is a request to temporarily step away from your job while maintaining your employment status. Your position is generally held for you, and you are expected to return on an agreed-upon date. A resignation letter is a formal notice that you are permanently ending your employment. Once accepted, it terminates the employment relationship. The key distinction: a leave of absence preserves your job; a resignation ends it. If you are unsure which path is right for your situation, a leave of absence is generally the lower-risk option — it keeps your options open while you address whatever is requiring your time away.

Is a Leave of Absence Letter Legally Required?

In many cases, yes — or at the very least, strongly recommended. If you are requesting leave under the FMLA, the ADA, USERRA, or a state-level paid family leave program, a written request is typically a necessary part of the formal process. Your employer may also require supporting documentation, such as a medical certification. Even when a formal written request is not mandated by law, submitting a formal leave of absence letter protects you. It creates a documented paper trail that confirms what was requested, what was agreed upon, and when. Without written documentation, disputes about your leave terms are significantly harder to resolve. General rule of thumb: Whenever you are requesting leave that extends beyond your available PTO — regardless of the reason — put it in writing.

What Happens After You Submit a Leave of Absence Letter?

After you submit your absence request letter, your employer or HR department will review it and determine whether the request meets company policy and any applicable legal requirements. If the leave qualifies under FMLA, your employer is generally required to respond within five business days of receiving the request — notifying you whether the leave is designated as FMLA-protected. For non-FMLA leaves, response timelines vary by employer policy. Once approved, you will typically receive written confirmation outlining the approved leave dates, whether your position will be held, and details about benefits continuation during your absence. Keep all written approvals with your copy of the original letter.

Can a Leave of Absence Request Be Verbal?

Technically, an employee can make an initial verbal request for leave — and in some situations, employers are required to designate leave as FMLA-protected even if the employee does not specifically invoke the FMLA by name. However, relying solely on a verbal request is risky. A verbal request provides no paper trail and leaves room for miscommunication about dates, terms, and approval status. In the event of a dispute — or if your employer later claims they were not properly notified — a written record is your strongest protection. The standard professional practice is to follow any verbal conversation with a formal written leave of absence letter that puts all terms on record. 360 Legal Forms makes this straightforward with a guided questionnaire and instant download.

What Is a Leave of Absence Letter?

A leave of absence letter is a formal written communication from an employee to their employer requesting a defined period away from work. It documents the nature of the request, the expected leave dates, and — where appropriate — any applicable legal protections, such as those under the Family and Medical Leave Act (FMLA) or the Americans with Disabilities Act (ADA).

In most cases, a leave of absence covers an extended absence that goes beyond an employee's available paid time off (PTO). It is generally used when an employee faces a qualifying personal, medical, or family situation that requires more time than standard vacation or sick days can provide.

A well-written formal leave of absence letter protects the employee's job status and gives the employer the information needed to plan for the absence. It also serves as official documentation should any dispute arise about the terms or approval of the leave.

Leave of Absence vs. Vacation — What's the Difference?

This is the most common point of confusion — and the distinction matters legally.

Vacation (PTO) is a routine, pre-earned benefit employees use for personal time, short trips, or rest.

A leave of absence is a separate, extended period away from work, often unpaid, that is granted for qualifying medical, family, personal, or military reasons.

According to the U.S. Department of Labor, the FMLA provides eligible employees with up to 12 weeks of unpaid, job-protected leave per year.

Note: Vacation is a benefit you use at your discretion. A leave of absence is a formal, often legally governed, extended absence.

Who Needs a Leave of Absence Letter?

A leave of absence letter is used by any employee who needs to formally request extended time away from work. Here is a breakdown of who typically uses one — and when:

Employees with a medical condition or surgery: Any employee who needs time off to recover from a procedure, manage a chronic illness, or address a serious health condition generally benefits from a formal leave request. In many cases, this type of leave may qualify for FMLA protection if both the employer and employee meet eligibility requirements.

Parents welcoming a new child: Employees who need time off for the birth, adoption, or foster placement of a child typically submit a leave of absence letter for family reasons to formalize parental or family leave.

Employees caring for a family member: When a spouse, child, or parent has a serious health condition, an employee may need extended time away from work. A leave of absence letter for personal reasons or family reasons documents this request formally.

Military service members and their spouses: Employees called to active duty — or whose spouse is — may qualify for military leave under the Uniformed Services Employment and Reemployment Rights Act (USERRA). A leave letter supports this request.

Employees dealing with bereavement or grief: Some employers provide bereavement leave beyond standard policy; a written letter supports an extended absence request in these situations.

HR managers and employers: HR professionals use received leave letters to document approvals, track leave balances, and ensure compliance with applicable laws. A written record protects the organization in the event of a dispute.

When is a leave of absence letter NOT strictly necessary?

If an employee is taking a short vacation within their available PTO, or a single sick day covered by company policy, a formal leave of absence letter is generally not required. The letter becomes important when the absence extends beyond standard PTO, involves a legal protection such as FMLA or ADA, or when an employer's policy specifically requires written documentation for extended time off.

Field	Details	Why It Matters
Employee Name & Contact Information	Full legal name, job title, department, phone number, and email address	Identifies the requesting employee and enables your employer to follow up quickly

How to Fill Out a Leave of Absence Letter (Step by Step)

Step 1 — Add Your Contact Information

Begin by entering your full legal name, job title, department, and the date you are writing the letter. Include your phone number and email address so your employer can contact you with questions or to confirm approval.

Step 2 — Address Your Employer

Write the full name and title of the person receiving the letter — typically your direct supervisor or your HR manager. Follow with the company name and mailing address. Addressing the letter to a specific person, rather than "To Whom It May Concern," signals professionalism and helps ensure the letter reaches the right decision-maker promptly.

Step 3 — Write a Clear Opening Statement

Open the body of the letter with a direct, professional statement of your request. State that you are formally requesting a leave of absence, identify the type of leave (medical, personal, family, military), and briefly note the reason without sharing more personal details than necessary.

Step 4 — Specify Your Leave Dates

Clearly state both your leave start date and your anticipated return to work date. If your return date is uncertain, such as with a medical leave, note that and provide your best estimate.

Step 5 — Reference Any Applicable Legal Protections

If your leave qualifies under the FMLA, the ADA (Americans with Disabilities Act), USERRA (for military leave), or a state-level paid family and medical leave law, reference the applicable protection by name. This puts your employer on clear notice that your absence may be legally protected and signals that you are aware of your rights.

Step 6 — Describe Your Transition Plan

Outline how your responsibilities will be covered during your absence. You might suggest a specific colleague to handle your work, offer to complete key tasks before you leave, or propose to remain available by email on a limited basis. This step demonstrates professionalism and reduces the operational burden on your team.

Step 7 — State Your Availability During Leave

Let your employer know whether you will be reachable during your absence and to what extent. For medical leaves, it is acceptable to note that your availability may be limited. For personal or family leaves, you can offer to check in periodically if needed and appropriate.

Step 8 — Attach Supporting Documentation

If your company policy or a legal protection requires documentation — such as a medical certification from a healthcare provider, military orders, or a birth certificate for parental leave — note in the letter that the relevant documents are attached. Keep a copy of all documents submitted.

Step 9 — Close Professionally and Sign

Close the letter by thanking your employer for their consideration and inviting them to contact you with any questions. Sign the letter with your full name. If submitting electronically, a built-in e-signature is legally valid under the UETA (Uniform Electronic Transactions Act) in most states.

Leave of Absence Letter Signing Requirements

In most cases, a leave of absence letter requires only the employee's signature. No notarization is typically required. The letter should be submitted to the employee's direct supervisor and/or HR department, per company policy.

For electronic submissions, an e-signature is generally valid under the UETA and the federal E-SIGN Act in most states. Always check your employer's specific submission requirements, as some organizations require a physical, signed copy on file.

What to Do With Your Leave of Absence Letter

Once your letter is complete, follow these steps:

1. Review for accuracy. Confirm all dates, names, and contact information are correct before submitting.

2. Attach supporting documents. Include any required medical certifications, military orders, or other relevant documentation your employer or applicable law requires.

3. Submit through the proper channel. Deliver your letter directly to your supervisor and HR department — by email, certified mail, or in person — per your company's leave request procedure.

4. Keep a copy for your records. Retain a signed copy of the letter and all attachments. This is your documentation in case any dispute arises regarding the terms or approval of your leave.

5. Follow up in writing. After submitting, request a written confirmation of receipt or approval from your employer. This creates a complete paper trail.

6. Note any response deadlines. If your leave is covered by FMLA or another federal protection, your employer is generally required to respond within a set timeframe. Check your state's requirements for additional obligations.
