What Is a Leave of Absence? A Guide for Employers

How do you keep a team running when a key employee suddenly needs weeks, or even months, away from work? A leave of absence is the mechanism that makes this possible, and how you handle it shapes your compliance, your team's morale, and whether that employee stays.

Paid time off is now standard: 80% of private industry workers had access to paid sick leave in March 2025, according to the U.S. Bureau of Labor Statistics. A formal leave of absence, though, follows very different rules than everyday vacation or a sick day.

This guide breaks down what a leave of absence is, the mandatory and voluntary types, FMLA eligibility, how long leave can last, whether it is paid, and the best practices US employers use to stay compliant and keep good people.

What is a leave of absence?

A leave of absence is an extended, employer-approved period away from work for a significant personal reason, such as a serious illness, childbirth, caring for a family member, or military service. Unlike routine vacation, it usually runs for weeks or months and may be paid or unpaid depending on the reason and the law that applies.

Some leave is protected by federal or state law, while other leave is granted at the employer's discretion. Employers often offer voluntary leave beyond legal minimums as part of the employee benefits that help attract and keep talent.

Before you set a policy, it helps to see how a leave of absence differs from the paid time off your team already uses.

How is a leave of absence different from PTO?

A leave of absence covers long, exceptional absences (often weeks or months), while paid time off covers short, routine breaks like a vacation or a sick day. PTO is almost always paid and accrues over time, whereas a leave of absence is frequently unpaid and tied to a specific qualifying event.

If you are still mapping out the routine side of time off, see our guide on how to calculate PTO.

With that distinction clear, here are the two categories every leave request falls into.

What are the types of leave of absence?

A leave of absence falls into two categories: mandatory leave, which employers must provide under federal or state law, and voluntary leave, which employers choose to offer as a benefit. Mandatory leave carries legal protections like job reinstatement, while voluntary leave is governed entirely by company policy.

The table below compares the two at a glance:

Each category deserves a closer look, starting with the leave you are legally required to provide.

What is mandatory leave?

Mandatory leave is time off employers must grant under law. The main federal sources are the Family and Medical Leave Act (FMLA), the Americans with Disabilities Act (ADA), and the Uniformed Services Employment and Reemployment Rights Act (USERRA) for military service. Many states add their own protected leave on top.

Common forms of mandatory leave include:

• FMLA leave: up to 12 weeks of unpaid, job-protected leave for qualifying medical and family reasons under the Family and Medical Leave Act.
• ADA accommodation leave: unpaid leave can be a reasonable accommodation for a disability under the Americans with Disabilities Act, sometimes beyond FMLA limits.
• Military leave: job-protected leave for service members with reemployment rights on return, protected by USERRA.
• State and local leave: many states mandate paid sick leave, family leave, or jury-duty leave that goes beyond federal rules.

When the law does not require time off, employers can still choose to offer it voluntarily.

What is voluntary leave?

Voluntary leave is time off an employer grants at its own discretion, outside any legal mandate. It carries no statutory job-protection guarantee, so eligibility, duration, and pay are set entirely by company policy. Employers use it to support staff through life events and to strengthen loyalty and retention.

Employers commonly offer voluntary leave for reasons such as:

• Sabbaticals: extended rest or study leave for long-tenured employees.
• Bereavement: time to grieve beyond a standard company allowance.
• Education: leave for a degree, certification, or professional development.
• Personal transitions: a relocation, adoption process, or caregiving need.

Because voluntary leave is discretionary, clear eligibility rules matter, which raises the question of who actually qualifies for FMLA in the first place.

Who is eligible for FMLA leave of absence?

To qualify for FMLA leave, an employee must have worked for a covered employer for at least 12 months, logged at least 1,250 hours in the prior 12 months, and work at a site with 50 or more employees within 75 miles. A covered employer is generally a private business with 50+ employees, or any public agency or school.

Beyond those thresholds, the leave must be for a qualifying reason. FMLA covers:

1. Birth and bonding: the birth of a child and bonding time within the first year.
2. Adoption or foster care: placement of a child with the employee.
3. Family care: caring for a spouse, child, or parent with a serious health condition.
4. Own health condition: a serious condition that prevents the employee from doing the job.
5. Military exigency: needs arising from a family member's active-duty service.
6. Military caregiver leave: up to 26 weeks to care for a covered service member with a serious injury or illness.

Meeting eligibility is only half the picture; employers also decide when to grant leave that FMLA does not cover.

When should you grant a voluntary leave of absence?

Grant voluntary leave when an employee faces a significant situation that falls outside FMLA or state law but still warrants time away, and when the business can absorb the absence. Approving it thoughtfully protects morale, signals that you value your people, and often brings employees back more engaged.

“As a third of employees feel the need to conceal mental illness, anxiety or stress-related reasons for taking a sick day, it's clear that there is still a high degree of stigma around mental health in the workplace.”, Dr. Hemal Desai, Global Medical Director, Aetna International

Employees often request voluntary leave for reasons like:

• Higher education: pursuing a degree or certification.
• Bereavement or family upheaval: extended time after a loss or major change.
• A sabbatical: a recharge after long tenure.
• A personal move or caregiving need: support during a life transition.

Once you decide to grant leave, the next practical question is how long it can run.

How long can a leave of absence last?

Duration depends on the leave type and your policy. FMLA provides up to 12 weeks (26 weeks for military caregiver leave) in a 12-month period. ADA accommodation leave has no fixed cap and is assessed case by case, while voluntary leave lasts as long as your policy allows, from a few days to a year or more.

Typical durations by leave type are shown below:

Durations are not always final, which leads to a common follow-up: can leave be extended?

Can a leave of absence be extended?

Yes, a leave of absence can often be extended, but it depends on the leave type, your policy, and the circumstances. FMLA rarely extends past 12 weeks, though ADA accommodation may require additional unpaid leave. Voluntary leave can be extended at the employer's discretion, as long as both sides agree in writing.

Handle extension requests differently by type:

• FMLA leave: extensions past 12 weeks are uncommon, but ADA leave may pick up where FMLA ends.
• Voluntary leave: extend when the situation warrants it and the business can accommodate it.
• Military leave: extensions follow the service commitment and federal reemployment rules.

Whether original or extended, the leave raises the question every employee asks first: will I be paid?

Do employees get paid during a leave of absence?

In the US, most statutory leave is unpaid. FMLA does not require pay, though employees can use accrued PTO during it. Some states mandate paid family or sick leave, and many employers offer paid parental, sick, or disability leave as a benefit. Whether leave is paid comes down to the applicable law and your own policy.

Employers often let workers run accrued vacation concurrently with unpaid leave; our breakdown of accrued vacation time explains how to track it.

Pay during leave also affects withholding, so it helps to understand how payroll deductions continue while someone is out.

When partial pay or benefits premiums are involved, an employee's net pay can shift, so communicate the numbers clearly before leave starts.

Unpaid stretches can also change how employer payroll taxes and contributions are calculated for the period.

Access to paid leave is uneven: only 27% of private-industry workers had access to paid family leave as of March 2023, according to the Bureau of Labor Statistics.

Clear pay rules are one piece of a bigger goal: managing leave well from request to return.

What are the best practices for managing a leave of absence?

The best way to manage a leave of absence is to set a written policy, apply it consistently, document every decision, and train managers to handle requests with empathy. Consistency protects you legally, and compassion protects morale and retention.

Follow these best practices:

1. Know the rules: stay current on federal, state, and local leave law.
2. Write a clear policy: cover eligibility, pay, documentation, and return-to-work steps in your handbook.
3. Assess each request on its facts: document the decision to ensure consistent, unbiased treatment.
4. Train supervisors: equip them to handle sensitive leave, from serious illness to bereavement, with care.
5. Plan coverage and re-entry: arrange interim coverage and a structured return so both sides succeed.

A written policy is far easier to build with the right tools behind it.

Consistent leave records also keep your payroll administration clean and audit-ready.

For larger teams, an automated payroll system makes tracking concurrent PTO and unpaid leave far less error-prone.

Getting the mechanics right matters, but the payoff shows up in something bigger: whether your people stay.

How does a leave of absence policy affect employee retention?

A clear, generous leave of absence policy directly improves retention. When employees can step away for health or family without fear, they return more loyal and productive, and job seekers weigh leave benefits heavily when choosing an employer. Treating leave as a strategic benefit, not just an obligation, lowers turnover.

Paid leave is also a hiring signal. As of 2025, 81% of private industry workers had access to paid holidays, per the Bureau of Labor Statistics, and candidates increasingly expect strong leave benefits.

Positioning leave as part of a competitive compensation package helps you attract and keep the people you want.

Predictable pay period practices reinforce the same trust that a fair leave policy builds.

Rounding out the package with supplemental pay and clear benefits makes your offer stand out.

If your team spans locations, a distributed workforce adds layers of state and local leave law to track.

Managing all of this, across policies, payroll, benefits, and compliance, is where a dedicated partner earns its keep.
