At some point in your career, you may need to request a leave of absence. Some common reasons include family or medical commitments, military leave, short- or long-term disability, or an extended vacation or sabbatical. Whatever the reason, it’s important to submit a formal request in writing. Taking time away from work isn’t always planned, but knowing your options ahead of time can make all the difference.
Understanding how leave policies work can help you make informed decisions, protect your job, and reduce stress during uncertain moments. This guide will walk you through what you need to know so you’re not caught off guard when life calls for a pause.

What is a leave of absence?

A leave of absence is a period during which someone is officially excused from their duties, usually due to personal, medical, family, or educational reasons. It can be paid or unpaid, depending on the specific circumstances and company policies. Paid leave might be granted for situations like medical or parental leave, while unpaid leave may require using accrued vacation time or going without pay. Employers typically require formal requests and documentation to approve a leave, and the process may vary depending on the organization’s policies and local labor laws. Understanding the terms and expectations ahead of time can help avoid misunderstandings and ensure a smoother transition both before and after your time away.

The duration of leave can vary widely from a few days to several months, depending on the reason and organizational policies. While it may feel like resigning, unlike a two weeks’ notice letter, this document states that you fully plan on returning to work. The length of a leave can range from a short break to an extended absence, based on your situation and company guidelines. Though stepping away might feel final, a leave request signals your intent to come back. It’s a formal way to pause without severing ties, giving both you and your employer clarity and reassurance.

Key characteristics of a leave of absence.

A leave of absence is more than just time away from work — it’s a structured arrangement that protects both the employee and the employer during significant life events. Understanding its core features can help you navigate the process with confidence and clarity.

Here are the defining traits of a leave of absence:

  • Official approval. The time off is formally granted by the employer, often following a written request and review process.
  • Job protection. Your role remains secure during your absence, with the expectation that you’ll return once the leave ends.
  • Exceptional reasons. Typically reserved for major personal, family, or medical situations, as well as military service or parental responsibilities.
  • Compensation varies. Depending on company policy and the nature of the leave, you may continue receiving pay or take unpaid time off.
  • Policy-driven. The terms of the leave, including duration, documentation, and eligibility, are guided by internal policies and sometimes legal regulations.

Knowing these characteristics can help you prepare, communicate effectively with your employer, and make informed decisions when life requires stepping away from work.

How leave of absence is different from time off.

While both a leave of absence and time off involve stepping away from work, they serve very different purposes and follow distinct protocols. Understanding the difference helps you choose the right option for your situation and ensures you meet your employer’s expectations.

Here’s how they differ:

  • Duration. Time off is usually short-term, like a few hours or days. A leave of absence often spans weeks or months.
  • Formality. Time off may be casually requested through a manager or scheduling system. A leave of absence typically requires formal approval and documentation.
  • Reason. Time off is often used for routine needs, such as vacation, personal errands, or minor illness. A leave of absence is reserved for major life events or serious circumstances.
  • Job protection. While vacation or sick days are part of your benefits, a leave of absence often includes specific job protection policies, especially under laws like FMLA.
  • Pay status. Time off is usually paid, depending on your benefits. A leave of absence can be paid or unpaid, depending on the reason and company policy.

Choosing between the two depends on the nature and urgency of your situation. Knowing the distinction helps you communicate clearly and plan responsibly.

How to write a leave of absence letter (with template).

When writing, keep in mind that most leave of absence request letters will require multiple signatures, including you as the requester, the supervisor, and in some cases, the HR department.

Now that you have a better understanding of how to write a leave of absence letter, let’s go over an example. Below is an example of a leave of absence letter template that demonstrates a typically followed structure:
