A leave of absence is a time away from work. This time varies from a few days to several months depending on the reason for the leave. In most cases, the reason is related to medical conditions or other family situations that require time.
Since it is a long leave, every company has its own policies on whether it is paid or unpaid. Also, a small number of leaves are required under the law, and the employer has to grant those. The rest are left to the company to allow or deny.
This article covers what leave of absence is, who is eligible for it, and how a request can be made & approved. The laws that protect a job during a leave are explained too.
There is also the HR side of leave. The payroll and the benefits continue while the employee is away. The health insurance stays in place as well. A leave of absence is one part of the broader human resources roles and responsibilities that an HR team manages.
Definition: Leave of Absence
A leave of absence is a formal time away from work for a specific reason. During this time, employees remain active on the records, but no work is being done. Therefore, the employee is expected to return once the leave is over.
It is different from paid time off and sick leave. Paid time off means a set number of days an employee can take breaks without giving a reason. Sick leave is meant for short illnesses. A leave of absence is for longer situations, like a serious medical condition or maternity leave.
Leaves are also either mandatory or voluntary. A mandatory leave is one the law requires the company to give, as long as the employee qualifies for it. A voluntary leave is one the company offers on its own terms, under policy. Most of the questions around a leave of absence come back to these two things, the reason behind it and the type it falls under.
Key Points At a Glance
A few things sum up how a leave of absence works:
- Formally approved: A leave goes through a request and is approved by the company on the basis of the reason.
- Longer than paid time off: The duration of it runs for weeks or months.
- Some leaves are protected by law: Depending on state law, certain leaves have to be granted.
- Pay is not fixed: A leave can be paid, unpaid, or partly paid, specific to a company.
- Job protection is limited: A leave keeps the job open only in specific cases, mostly the ones the law.
Leave of Absence vs PTO vs Sick leave
A leave of absence, paid time off, and sick leave all mean time away from work, but they are used for different things. The table below shows how they compare.
Paid time off is the time an employee takes for short personal breaks. There is no need to give a reason for it. The company decides how much time an employee gets and how it is used. The rules are set out in its PTO policy.
Sick leave is a separate bank of time meant for short illnesses. Many states and cities have their own sick leave laws, so the amount depends on the location. It works for a cold or a short doctor visit.
A leave of absence covers the situations the other two are too short for. It runs into weeks or months, and the reason behind it is a major one. The common reasons are a serious medical condition, a new child, or care for a family member.
LOA vs Short-Term Disability
Short-term disability and a leave of absence are easy to mix up because they can overlap. Short-term disability is an insurance payment that covers part of an employee's income during a medical leave. A leave of absence is the job status that holds the position. An employee can be on both at the same time during a medical recovery.
LOA vs Sabbatical
A sabbatical is one type of voluntary leave. It is given for long service at the company or for study and research. Some companies pay the employee during a sabbatical. A regular leave of absence is unpaid in most cases, unless a law says otherwise.
Types of Leave of Absence
Every leave falls into two categories: mandatory and voluntary. Within those two groups are the named types most employees deal with.
Mandatory (Legally Protected) Leaves
These leaves are protected by the federal and state law for an employee meeting certain conditions. The company has to approve such leaves while keeping the job open.
- FMLA leave: Applicable at companies with 50 or more employees within 75 miles. It can be offered to employees who have worked for 12 months and 1,250 hours. Employees are eligible for up to 12 weeks off in 12 months for a serious medical condition, family care, or a new child. The leave is unpaid, and the job is protected.
- ADA-related leave: It is meant for Americans with Disabilities. There is no fixed duration, determined based on the employer's needs.
- Military leave (USERRA): It is an unpaid leave reserved for employees leaving work for military service. It can add up to five years across a career. The pay and duration of leave vary based on the case and the state.
- Jury duty: It protects an employee's job while they have to serve on a jury.
- State paid family and medical leave: These leaves are run by individual states on top of FMLA. These programs pay part of the wages during family or medical leave. The rules, the length, and the pay depend on the state.
Voluntary (Employer-Discretion) Leaves
Voluntary leaves are decided by a company on its own. So there is complete freedom in duration and terms to avail them. They cover reasons that fall outside the mandatory leave types.
- Personal leave: Any leave for personal reasons. The company approves it one at a time, and whether it is paid or unpaid is the company's choice.
- Extended medical leave: After FMLA runs out, extended medical leave is up to the company.
- Sabbatical: A longer break either offered after working for a certain time in a company or taken for study.
- Educational leave: Leave taken to complete a degree or certification. It is unpaid unless the degree is associated with a company and meant to benefit them.
- Bereavement leave: Short leave taken after a death in the family. The bereavement leave guide covers the length and the pay in detail.
- Unpaid personal leave: Longer unpaid time off for personal reasons the company agrees to. There is no pay, and the job is held only if the policy says so.
Intermittent vs Continuous Leave
Leave does not have to come in one block. Continuous leave is taken all at once, like a few weeks to recover from surgery. Intermittent leave is taken in small, separate blocks spread over time.
Intermittent leave is taken during a condition that might come and go, such as headaches, mental health, or physical therapy. An employee can take leave for a few hours each week rather than one long stretch away. This keeps the person working while they get regular care.
Paid vs Unpaid leave
Pay depends on the type of leave and the law behind it. FMLA is unpaid at the federal level, so a 12-week FMLA leave carries no wages on its own. Some states fill that gap with their own paid programs. These include California PFL, New York PFL, Massachusetts PFML, Colorado FAMLI, and Washington PFML.
Short-term disability can also cover part of the pay during a medical leave. On top of that, a company can offer paid leave beyond what any law requires. Whether a specific leave is paid depends on the state, the reason, and the company policy.
Short-Term, Extended, and Indefinite Leave
Leave also groups by how long it lasts. Short-term leave runs under 30 days, for a quick recovery or a personal matter. Extended leave runs from 30 days up to the 12-week FMLA limit. Indefinite leave has no fixed end date. It is rare, and it shows up mainly with medical conditions that have no clear timeline, handled with care under the ADA.
Common Reasons Employees Take a Leave of Absence
Most leave requests come from a handful of situations.
- Serious illness: An FMLA-protected leave meant for a health condition that needs a longer time to recover.
- Surgery recovery: If a person has gone through a planned operation and needs time to recover.
- Family care: FMLA-covered time to look after a spouse, child, or parent with a serious health condition, unpaid unless a state program adds pay.
- A new child: FMLA leave for a birth, adoption, or placement, with a state PFL program paying part of the wages in some states.
- Mental health: Care for a mental health condition that can fall under FMLA or the ADA, with the pay following the same rules as other medical leave.
- Military service: USERRA-protected time for duty or family military caregiver leave, unpaid for the service period but with strong return rights.
- Personal or study reasons: A sabbatical, travel, or a degree, granted at the company's discretion and unpaid in most cases.
Who is Eligible For a Leave of Absence
Eligibility depends on which framework the leave falls under. There are three main ones to know.
FMLA Eligibility
FMLA is a federal law, and it has a few conditions an employee needs to meet.
An employee who meets all of these can use FMLA leave for a serious health condition, a new child, or family care. Remote work has made the size rule harder to apply, because the 50-employee count goes by the office an employee reports to rather than the home they work from. The full rules come from the U.S. Department of Labor.
ADA-Related Leave
The ADA does not give a fixed amount of leave the way FMLA does. Here, leave is one form of reasonable accommodation for an employee with a disability. There is no set length, since it depends on what the employee needs to keep working.
In most cases, ADA leave applies after FMLA is used up, or when FMLA does not apply at all. The employer and the employee go through an interactive process to decide what accommodation is reasonable. These cases are the ones where legal counsel gets involved.
State and Local Leave Laws
Coverage changes a lot from one state to another. Some states run their own paid leave programs, like California, New York, and Massachusetts. New Jersey, Washington, Colorado, and Oregon have set up programs too.
A few cities add their own rules on top of the state ones. For an HR team that runs payroll across several states, this is something that keeps changing and has to be watched. The National Partnership for Women & Families keeps a tracker of the current programs.
How to Request a Leave of Absence
The process is close to the same at most companies. It runs through six steps, in order.
Step 1. Work Out The Type Of Leave Needed
The first thing is to match the reason to a leave category. It will decide whom to reach, the manager or HR, along with the relevant documents. However, when working on medical and personal leave, these things will not work the same way.
Step 2. Read the Company Leave Policy
Companies have a written leave policy explaining the types of leave and how they can be availed. So, before applying for any leave, go through these documents.
Step 3. Tell the Manager And HR
The employee should inform HR, manager, or the concerned person as early as possible. If leave is for preplanned surgery or parental leave, then FMLA requires 30 days' prior notice. For a sudden leave, the notice should go in as soon as possible. It is best to tell the manager first for context, and then HR for the process.
Step 4. Put the Request in Writing
HR teams prefer the request in writing. The request should mention the type of leave, expected duration, and relevant documents. Here is how it can be written:
“I am writing to request a leave of absence starting [date] for about [length]. The leave is for [reason]. I will send any certification that is needed, and I can be reached at [contact] for anything urgent while I am away.”
Step 5. Complete the Paperwork
The documents needed to submit depend on the leave. For example, FMLA leave requires medical certifications, while USERRA needs military orders. Other reasons need whatever supports the request. For a medical leave, the employer can ask for a second or third opinion in certain cases.
Step 6. Hand Over the Work
Before the leave begins, the work needs to be handed over. The employee hands off active tasks, briefs whoever is covering, and lets the team know the plan. This is the step that gets missed, even when the paperwork is fine.
The Employer's Role in Managing Leave Requests
Once a request arrives, the employer takes over. HR and the manager share four main duties here.
The five-day notice is the one that gets missed most. A late response can hurt the company if the leave is questioned later.
Most of the trouble is in the handling. Policies get applied unevenly, and one employee gets something another was refused. A gap like that is where a discrimination claim starts. Informal denials are another risk, since a decision made in a quick message leaves no record to fall back on. The return-to-work step causes problems when nobody has set out what the role is on return.
Leave Management as a Coordination Problem
Most guides treat a leave as a compliance task. It is also a coordination task, and that side gets less attention. A single request pulls in several people and systems that each hold a piece of it.
The gaps show up in the handoffs. A manager approves a two-week leave in a direct message and never loops in HR, so no record gets made. HR approves the leave but forgets to tell payroll, and the PTO keeps adding up as if the employee were still at work. A benefits deduction gets missed along the way, and the employee comes back to a claim they did not know was open.
Each of these traces back to one piece of information that stayed in someone's inbox. A lot of HR teams run this on spreadsheets and email, which works at low volume but gets harder as the number of leaves grows. The coordination gap is where a structured process for requests helps, and the next section covers the tools for it.
Managing Leave With the Right Technology
HR does not run leave on one tool. It takes a mix, and the mix depends on how much leave there is to manage.
HRIS and Leave Management Modules
Companies need to store leave data somewhere, and the HRIS platform can help with it. It holds all the records such as leave balances, entitlements, and status. BambooHR, Rippling, and Workday are the names that come up most.
Dedicated Absence Management Platforms
When volume grows, a general HRIS starts to strain, and some companies bring in a tool built only for absence. They handle large-scale FMLA work and track intermittent leave hour by hour. AbsenceSoft and Larkin are two examples, used mostly by larger companies.
HR Ticketing For the Leave Request Process
A leave request is often received as a message to a manager or HR. The message might be lost, that’s where an HR ticketing system catches the request at that first step, points it to whoever owns the next move, and keeps a record of it. Suptask runs this inside Slack, close to where the messages already land. It takes the request and moves it to the right place, though the leave itself still lives in the HRIS.
What Happens to Health Insurance During Leave
Health coverage is often purchased for a year and doesn’t end the moment a leave starts. During an FMLA-protected leave, the employer is obliged to continue the health plan just like an employee is working with them. The employee still owes their share of the premium.
Paying that share gets trickier on unpaid leave, since no paycheck is coming in to take the deduction from. The employer bills the employee for their portion during the leave, or adds it up and collects it once they are back.
The best practice to learn what happens to health insurance during a leave is to read company policy and what will happen to the plan.
Legal Protections and Employer Obligations
Several laws govern protected leave, and more than one can apply to the same case.
On top of the specific laws, there is a rule that cuts across all of them. An employer cannot punish an employee for taking leave that the law protects. A demotion, a firing, or a cut in hours tied to protected leave is unlawful.
The article explains how these laws work in general. It is not legal advice, and a specific case is worth checking with an employment attorney.
Frequently Asked Questions
What is a leave of absence?
A leave of absence is approved time away from work that runs longer than a sick day, tied to a set reason like a medical condition, family care, or a personal matter. The employee keeps their job status during the leave and is expected to return. It can be paid or unpaid.
What is the difference between a leave of absence and PTO?
PTO is paid time an employee uses for short breaks, with no reason needed. A leave of absence is longer, tied to a qualifying reason, and it can involve documentation or legal protection. PTO covers days. A leave covers weeks or months.
What is the difference between a leave of absence and short-term disability?
A leave of absence is the job status that holds the position open. Short-term disability is an insurance payment that replaces part of the income during a medical leave. The two can run at the same time during a medical recovery.
What is the difference between FMLA and ADA leave?
FMLA gives eligible employees up to 12 weeks of unpaid, job-protected leave. ADA leave is a reasonable accommodation for a disability, with no set length, worked out through an interactive process. ADA leave tends to apply after FMLA is used up, or when FMLA does not cover the employee.
What are the most common types of leave of absence?
The most common are medical leave for a serious condition, parental leave for a new child, family care leave, military leave, and personal leave. Some are protected by law, such as FMLA leave. Others are granted at the company's discretion under its own policy.
How long can a leave of absence last?
It depends on the type. FMLA gives up to 12 weeks in a 12-month period, or up to 26 weeks for military caregiver leave. Company-granted leave can be shorter or longer under policy. Indefinite leave has no set end and is uncommon.
Is a leave of absence paid or unpaid?
It depends. FMLA is unpaid at the federal level, though an employee can use PTO for income during it. Some states offer paid family and medical leave that covers part of the wages. Short-term disability and company-paid leave can also apply.
Can an employer deny a leave of absence?
For voluntary leave under company policy, yes, an employer can deny the request. For legally protected leave like qualifying FMLA leave, no, an eligible request cannot be denied. Denials still have to follow the policy the same way for everyone, or they create legal exposure.
What is intermittent leave and who qualifies?
Intermittent leave is taken in small, separate blocks rather than one stretch, used to manage an ongoing condition. It pairs with FMLA for a chronic serious health condition that needs regular care. Eligibility follows the same FMLA rules as continuous leave.
Does a leave of absence protect my job?
It depends on the type. Legally protected leave, like qualifying FMLA leave, keeps the job open and gives the right to return to the same or an equal position. Discretionary leave under company policy protects the job only as far as the policy says.
Closing
A leave of absence is one of the heavier processes HR runs, because a single request touches the law, the benefits, the payroll, and the manager relationship all at once. Getting it right means handling the rules and the coordination together. A clean approval still fails if payroll and benefits never hear about it.
For HR teams that deal with a steady flow of leave, routing each request through a ticketing workflow keeps it from getting lost between email, direct messages, and the HRIS. An HR ticketing system gives every request an owner and a record from the first message.
