Leave of Absence Letter

Every year, millions of people take some sort of leave from work. According to the U.S. Bureau of Labor Statistics¹, in January 2022 alone, nearly 8 million workers missed work due to illness, injury, medical issues, or appointments. In comparison, the number was about half that a year earlier. These figures don’t account for other reasons why people may need to take off work for extended periods of time. Health and medical leave is common. And so are maternity and paternity leave, personal leave, and time away for civic, military, and family reasons. At some point in your career, you may need to take an unexpected leave of absence from your job. In such an event, it’s a good idea to already be familiar with how to write a leave of absence letter. It's also wise to know the company policy about paid and unpaid leave, job-protected leave, and eligible employees before making a request. Understanding company policies can help you plan better and avoid a potentially adverse outcome resulting from assumptions or misunderstandings. In this article, we’ll discuss what constitutes a leave of absence, why you might need one, and how to write your letter.

What is a leave of absence request?

A good percentage of employers offer their employees paid time off (PTO) and vacation time. Some may structure it in categories for specific intentions (e.g., sick days, personal days, vacation time). Others may offer a predetermined amount of time for use however employees please, whether for medical leave or other reasons. A leave of absence is a situation in which an employee asks and receives permission from their employer to take an extended amount of time off from their job. In such a situation, this is a little different than paid leave benefits. While it can apply to various types of leave, a leave of absence is typically reserved for circumstances that are unique and when the amount of paid leave days is insufficient.

Common reasons why people put in a leave of absence request

As an employee, you may find yourself in one of the following situations and want to submit a formal leave of absence letter requesting extended time off:

  • Sick leave, including prolonged health issues and other medical reasons.
  • Mental health, sabbatical, extended vacation, or other personal reasons.
  • Caring for family members.
  • Military leave, jury duty, or civic obligations.
  • Bereavement.
  • Finishing education.

Maternity and paternity leave are also common requests. This isn’t a comprehensive list. But does represent events for which you might make a leave request official in the form of a formal letter.

What to include in a leave request

When you ask for a leave from work, your employer will need specific information for decision-making and operational purposes. Here's what to include in your formal request.

Reason for leave of absence

Outline to your employer why you’ll need to take extended leave. Keep in mind, certain types of leave requests are mandated by law to be approved by employers. These include for purposes involving the Family and Medical Leave Act (FMLA), Emergency Family and Medical Leave Act (EFMLA), Americans with Disabilities Act (ADA), jury duty, and military service. For other, more personal reasons, you may be a little more general, leaving small, private details out.

How much time you’ll need

Outline to your employer how much time you expect to be gone from your job. This will help them plan for continuity during your absence. Remember to add a start date

and return date. If you aren’t sure about the latter due to extenuating circumstances, provide an estimated date.

Offer a work plan

Depending on the nature of your job, it may be difficult for your employer to fill your shoes in your absence. To help facilitate your absence, it’s a nice gesture to offer help.

  • Provide contact information for critical questions.
  • Train a replacement (time permitting).
  • Create a detailed employee handbook or SOP for an easier transition.

This is not required to include in your letter. But if it's feasible per your circumstances, your employer will appreciate any efforts to help.

Respect and appreciation

Lastly, end your leave of absence request letter with a polite thank you to show your employer or HR team appreciation for their support.
