What Is a Leave of Absence? Types, Laws, and Employer Guidelines

An employee walks into your office with a request you weren't expecting: they need extended time away from work. Maybe it's for surgery and recovery. Maybe they're welcoming a new baby or caring for a seriously ill parent. The request is genuine, the need is real, and suddenly you're facing questions that don't have simple answers. 

What does the law require? Will they be paid? How long can they be gone? Do you have to hold their job? What happens to their benefits? If you're running a small business without a dedicated HR team, navigating a leave of absence request can feel overwhelming. But with a clear understanding of what leave is, which laws apply, and how to handle the process, you can respond confidently and support your employee through a challenging time. This guide walks you through what you need to know. 

What is a leave of absence? 

A leave of absence (LOA) is an approved, extended period of time away from work for circumstances that fall outside regular paid time off. Unlike vacation days or sick time that employees use at their discretion, a leave of absence is requested for specific situations. 

Some leaves of absence are governed by federal, state laws, or local law like the Family and Medical Leave Act (FMLA), state paid family and medical leave, the Americans with Disabilities Act and the Uniformed Services Employment and Reemployment Rights Act (USERRA), and eligible employees with qualifying reasons have the right to take them. However, not all  offer protections such as benefits continuation or job protection, but may still be requested by the employee.  

Leave can be paid or unpaid depending on the circumstances, the laws that apply, any applicable state funds, potentially disability insurance coverage, and your company's policies.  

The key distinction between LOA and paid time off (PTO) is that a leave of absence is formal, documented, and tied to a specified reason and timeline. 

Leave of absence vs. paid time off

Understanding the difference between PTO and a leave of absence is important when evaluating a request. Here's how they compare: 

PTO is flexible and routine. A leave of absence is extended, formal, and typically triggered by life events that require time away beyond what regular time off can cover. 

Leave required by law

Several federal laws require covered employers to provide leave for specific reasons, including, for example: 

Family and Medical Leave Act (FMLA): The FMLA allows eligible employees to take up to 12 weeks of unpaid, job-protected leave per year for the birth or adoption of a child, to care for a family member with a serious health condition, for their own serious health condition, or for qualifying military family reasons. The U.S. Department of Labor provides comprehensive guidance and forms for FMLA administration. 

Uniformed Services Employment and Reemployment Rights Act (USERRA): USERRA protects the job rights of employees who leave work for military service, including training and deployment. Generally, service members can be absent for up to five years and retain reemployment rights. 

Jury duty and witness leave: Federal law protects employees from termination for serving on a federal jury, and many states require employers to provide time off for jury duty or testifying as a witness. 

State leave laws and paid family leave programs

A growing number of states have enacted their own family and medical leave programs. States like California, Colorado, Connecticut, Delaware, Maine, Massachusetts, Minnesota, New Jersey, New York, Oregon, Washington, and others operate paid leave insurance programs that provide wage replacement, job protection, or both. These programs are typically funded through employee and employer payroll contributions. 

State laws may also provide entitlements beyond federal requirements, including pregnancy disability leave, paid sick leave, domestic violence leave, or crime victim leave. If you have employees in multiple states, it's important to check each state's official guidance to understand what applies. HR compliance support can help you navigate the patchwork of state obligations that small businesses face. 

Personal leave

Not all leave is protected. Many employers offer personal leave as a way to support employees during significant life moments. Common types include: 

• Educational leave for professional development or continuing education
• Sabbatical leave for rest, travel, or personal projects
• Personal leave for circumstances that don't fit other categories

Personal leave can be a powerful retention tool. When employees know their employer will work with them during challenging times, trust deepens and loyalty grows. Because these requests often fall outside statutory leave requirements, employers may have greater discretion in determining whether leave can be approved, subject to applicable law and company policy. 

Who qualifies for FMLA leave?

Here's something many leave-of-absence guides don't emphasize: the FMLA only applies to private employers with 50 or more employees within a 75-mile radius. If your company is smaller than that, you're not legally required to provide FMLA leave. That doesn't mean you can't offer it, but the federal job protection and benefits continuation rules don't automatically apply to you. Though you are not covered under federal FMLA, you may be covered under a similar state or local program.

For employers who are covered by the FMLA, an employee qualifies for leave if they meet all of these criteria: 

• They've worked for your company for at least 12 months (not necessarily consecutive)
• They've worked at least 1,250 hours in the 12 months before the leave starts
• They work at a location where the company employs 50 or more people within 75 miles
• They have a qualifying reason, such as: 
  • Birth or adoption of a child
  • A serious health condition that prevents them from working
  • Caring for a spouse, child, or parent with a serious health condition
  • Qualifying military family reasons

If the FMLA doesn't apply to your business, you'll rely on state law (if your state has one), and your own company policy. This is where small business owners have the most flexibility and the most risk, because handling leave inconsistently can lead to claims of discrimination. Access to HR experts can make a meaningful difference when you're navigating these situations. 

Is a leave of absence paid or unpaid?

The short answer: it depends. 

Under federal law, FMLA leave is unpaid. But that doesn't mean the employee must go without income during their time away. Pay during a leave of absence can come from several sources: 

• State paid family and medical leave programs in states that operate them, which provide partial wage replacement funded through payroll contributions.
• Short-term disability insurance, if the leave is due to the employee's own medical condition and they have coverage.
• Accrued paid time off, which employees can often use alongside unpaid leave to maintain some income.
• Voluntary employer pay, if your company chooses to offer paid leave as a benefit.

Wage replacement vs. protected leave

It is important to distinguish wage replacement from leave protection. A program may replace part of an employee’s income without independently protecting the employee’s job or benefits. In some situations, wage-replacement benefits and legally protected leave run at the same time.  but a state wage replacement program may provide benefits for a time that exceeds what the employer has approved. 

Some wage-replacement programs include a waiting period before payments begin. Employees may also qualify for more than one source of income during leave, such as state benefits, disability insurance, accrued PTO or employer-provided pay. These sources may need to be coordinated because one benefit can affect the amount payable under another. 

Pay and benefits during FMLA leave

There's also a pay nuance for exempt employees under the Fair Labor Standards Act. If a salaried exempt employee takes intermittent FMLA leave (a few hours or days at a time), you can generally deduct their pay in hourly increments for the time they're out. 

Even when the leave itself is unpaid, employees on FMLA leave are entitled to continued group health insurance on the same terms as if they were working for the duration of their time on FMLA. That means you continue their coverage, and they continue paying their share of the premium. For small business employee benefits, this continuation can be administratively complex, especially if you're managing it manually. 

How long can a leave of absence last?

The length depends on the type of leave: 

FMLA leave: Up to 12 weeks in a 12-month period for most qualifying reasons; up to 26 weeks for military caregiver leave 

State leave programs: Varies by state, typically ranging from 8 to 12 weeks, though some states offer longer periods 

Personal leave: Set by your company policy, ideally with a defined return date. 

For personal leave, it's important to establish a clear end date and document it in writing. Open-ended leave creates uncertainty for everyone and makes workforce planning nearly impossible. 

Continuous vs. intermittent leave

A leave of absence may be continuous, meaning the employee is away for an uninterrupted period, or intermittent, meaning the employee takes leave in separate blocks of time. Intermittent leave may include recurring medical appointments, occasional days away from work, or a temporarily reduced schedule. Employers should carefully document and track intermittent leave when it is protected by federal, state, or local law. 

How to handle a leave of absence request

When an employee requests leave, a clear process can help both employers and employees navigate the request. Here's what to consider step by step: 

1. Review the request against applicable laws

Determine whether the leave is covered by the FMLA, ADA, USERRA, or state law. Consider whether you're a covered employer under each law and whether the employee meets the eligibility requirements. If you're not sure, this is a good time to reach out to experts.  ADA In addition, consider how you have handled similar requests in the past.

2. Respond in writing and document the decision

Let the employee know whether the leave is approved, which law or policy applies, how long it will last, and what's expected during and after the leave and provide any required notices that pertain to the leave. The Department of Labor provides standard FMLA forms that many employers can use even when the law doesn't require them, because they help clarify expectations and create documentation.

When medical certification is appropriate, focus the documentation on the employee’s functional limitations, work restrictions and expected duration of leave rather than requesting unnecessary details about the diagnosis. Use a consistent process and store medical information separately and confidentially. 

3. Sort out pay and benefits during the leave

Confirm how the employee will be paid (or whether the leave is unpaid), whether they can use accrued PTO, and how health insurance will continue. If the employee funds benefit premiums, explain how and when the employee should pay for them in an unpaid leave scenario. 

 4. Coordinate coverage

Plan how the employee's work will be handled while they're out. Reassigning duties, hiring temporary help, or redistributing tasks can ease the transition for your team. 

5. Track the leave time 

If the leave is intermittent (a few hours or days at a time rather than a continuous block), you'll need to track it carefully to ensure you're applying the law correctly. This is where leave administration gets complicated quickly. 

6. Plan the return to work

Before the employee returns, confirm their start date, discuss any accommodation needed, and if the leave was medical, determine whether you need a fitness-for-duty certification. If the leave was related to workers' compensation, coordinate with your carrier on return-to-work protocols. 

Having your leave policies detailed in your employee handbook helps set clear expectations. A documented process helps promote consistency, which can mitigate risk and support decision-making. 

What should a leave of absence policy include? 

A written leave of absence policy can help employers establish a consistent process for handling requests and setting expectations. Depending on the size of the organization, applicable laws, and company practices, a policy may address: 

• Who is eligible for leave and for what reasons, making sure these reasons are consistent with applicable law
• How employees should request leave
• Documentation requirements
• Whether leave is paid or unpaid
• How time off and other wage replacement may apply
• How benefits are handled during leave
• Expectations for communication during leave
• Return-to-work requirements

Can an employer deny a leave of absence request?

It depends on the type of leave. 

Leave protected by law generally cannot be denied if the employee is eligible and has a qualifying reason. For example, denying FMLA leave to an eligible employee can result in a complaint to the Department of Labor or other action. In some circumstance, leave of absence may also be considered a reasonable accommodation under the ADA, and employers should evaluate those requires in accordance with applicable law. 

When a leave of absence is not protected by applicable law, an employer may have more discretion in determining whether the leave can be approved. Employers should consider the circumstances of the request, applicable workplace policies and business needs, and apply their policies consistently. 

If a request for non-protected leave is denied, employers should document the reason for the decision and apply their policies consistently in similar circumstances. Clear documentation can help support the business rationale behind the decision. 

Moving forward with confidence

Handling a leave of absence well is one of those moments that defines your workplace culture. When employees know you'll support them through serious illness, a new child, or a family crisis, they're more likely to return, to stay, and to bring their best work when they're back.
