An employee tells a supervisor on a Friday afternoon that she needs surgery and will be out "for a while." By Monday, HR has to answer several questions at once. Is she eligible for FMLA leave? Does the ADA apply? Does a state program pay part of her wages? Who tells payroll, who collects the health premium, and what happens if she is not ready to come back on the date she gave?
That bundle of questions is leave management. This guide explains what the term covers, maps the laws that most often apply, and sets out a core process you can run the same way every time. Each section points to a detailed post, so use this page as the map and the linked posts as the manual. It is part of our Leave and Accommodation Management Guide.
What Is Leave Management?
Leave management is the set of policies, procedures, records, and decisions an employer uses to handle employee time away from work. It covers:
- Policy. What leave you offer, who qualifies, and how employees ask for it.
- Legal entitlement. Leave that a federal, state, or local law requires you to give, with rules on job protection, benefits, and notices.
- Administration. Intake, eligibility decisions, notices, medical documentation, tracking, and return to work.
- Coordination. Hand-offs between HR, managers, payroll, benefits, and, for a work injury, the workers’ compensation carrier.
It helps to sort leave into two groups from the start.
| Dimension | Mandated leave | Voluntary leave |
|---|---|---|
| Source | Statute or regulation | Employer policy or contract |
| Examples | FMLA leave, leave as an ADA or PWFA accommodation, military leave, state family, medical and sick leave, jury duty | Vacation, PTO above any legal minimum, sabbaticals, personal leave |
| Who sets the rules | The law, which your policy cannot reduce | You, although a written policy can bind you once published |
| Main risk | Interference, discrimination, or retaliation claims | Inconsistent treatment and wage claims |
Most hard cases involve mandated leave, and most of those involve more than one law at the same time.
The Laws Behind Leave Management
Each law below answers a different question, covers a different set of employers, and gives a different amount of time. One absence can fall under several of them. For a longer treatment, including wage and hour issues, see Leave Management Laws: FMLA, ADA, FLSA and More.
| Law | Employers covered | What it provides | Time limit |
|---|---|---|---|
| FMLA | Private employers with 50 or more employees in 20 or more workweeks of the current or prior year; all public agencies; public and private elementary and secondary schools | Unpaid, job-protected leave with group health coverage maintained | 12 workweeks in a 12-month period; 26 for military caregiver leave |
| ADA | Employers with 15 or more employees | Reasonable accommodation, which can include leave, unless it causes undue hardship | No fixed number |
| PWFA | Employers with 15 or more employees | Reasonable accommodation of known limitations related to pregnancy, childbirth, or related medical conditions, which can include leave | No fixed number |
| USERRA | All employers, regardless of size | Leave for uniformed service and reemployment afterward | Generally a cumulative five years of service with that employer, with exceptions |
| Workers’ compensation | Set by each state | Medical care and wage replacement for work-related injury or illness | Set by each state |
| State and local leave laws | Varies | Family and medical leave, paid sick leave, and other protected time off | Varies |
FMLA
The Family and Medical Leave Act gives an eligible employee up to 12 workweeks of unpaid leave in a 12-month period for the birth or placement of a child, a serious health condition of the employee or of a spouse, child, or parent, and certain military family needs. To be eligible, the employee must have 12 months of service, 1,250 hours of service in the 12 months before leave starts, and a worksite where the employer has 50 or more employees within 75 miles. The employer must keep group health coverage in place on the same terms and restore the employee to the same or an equivalent position.
The FMLA is also the most procedural of the leave laws. It sets deadlines for employer notices, rules for medical certification, and a three-year recordkeeping requirement. Start with FMLA requirements for employers.
ADA
The Americans with Disabilities Act does not create a leave entitlement by name. It requires reasonable accommodation for a qualified individual with a disability, and the EEOC’s position is that unpaid leave is one form of accommodation an employer must consider, even when the employer offers no leave as a benefit, the employee is not eligible under its policy, or the employee has used up the leave the policy provides. The FMLA regulations make the same point from the other side: FMLA gives 12 weeks, while the ADA allows an indeterminate amount of leave as an accommodation, barring undue hardship.
Two practical consequences follow. First, the end of FMLA leave is not the end of the analysis. Second, a policy that ends employment automatically after a fixed period of leave, or that requires an employee to return with no restrictions, needs an exception process for disability. See ADA accommodations: an employer overview, when leave becomes a reasonable accommodation, and "100% healed" and maximum-leave policies.
PWFA
The Pregnant Workers Fairness Act requires covered employers to accommodate known limitations related to pregnancy, childbirth, or related medical conditions unless the accommodation would cause undue hardship. Leave is one possible accommodation, including for recovery from childbirth and for health care appointments. The law also runs the other way: an employer may not require an employee to take leave when another reasonable accommodation would let her keep working.
An employee who has no FMLA eligibility at all, such as a new hire, may still be entitled to leave under the PWFA. The EEOC’s implementing rule at 29 CFR Part 1636 has been subject to a court ruling affecting part of it; check the current status at eeoc.gov before relying on details in the rule. The statute itself is unaffected. See Pregnant Workers Fairness Act: an employer guide.
USERRA
The Uniformed Services Employment and Reemployment Rights Act applies to every employer, including one with a single employee. An employee who leaves for uniformed service is treated as on a furlough or leave of absence, and on timely return is generally entitled to the position he or she would have reached if employment had not been interrupted. The regulations call this the escalator position. The employee may give notice of service orally or in writing, and no particular form is required. See USERRA leave and reinstatement.
Workers’ Compensation
Workers’ compensation is a state insurance system, not a leave law, but a work injury usually produces an absence. When the injury is also a serious health condition, the workers’ compensation absence and FMLA leave may run at the same time if the employer gives proper notice and designates the leave. An employee on FMLA leave may decline a light-duty offer and stay on unpaid FMLA leave until the entitlement runs out, although wage-replacement benefits may stop as a result. State anti-retaliation rules also apply. See FMLA and workers’ comp concurrent leave.
State and Local Laws
Federal law is the floor. Many states and some cities have their own family and medical leave statutes, paid family and medical leave insurance programs, paid sick leave requirements, and smaller entitlements such as leave for jury service, voting, school activities, or domestic violence. Because state requirements change, confirm current coverage with each state labor agency.
The FMLA does not override a state or local law that gives greater family or medical leave rights. Where both apply, you comply with both, and leave that qualifies under both counts against both entitlements at once. Where only one applies, the time may not run together, which is how an employee can end up with more total leave than either law provides alone. See paid sick leave laws by state, the paid family leave comparison chart, and the multi-state leave laws compliance guide.
The Core Leave Management Process
The laws differ, but a sound process has the same six steps whichever law applies. The detailed version is in our leave management workflow from request to return.
- Intake. Route every absence of more than a few days, and every request that mentions a health condition, pregnancy, a family member’s care, or military service, to one place. Employees do not have to name a law. Under the FMLA they need only give enough information for the employer to see that the leave may qualify, and the same is true in practice of accommodation requests. See creating a single intake process for leave.
- Classification. Test the request against every law, not only the first one that fits. Ask which laws cover the employer, which the employee is eligible for, and which reasons apply.
- Notices and documentation. Send the notices each law requires, on time. For the FMLA that means an eligibility notice and a rights and responsibilities notice within five business days of the request, and a designation notice within five business days of having enough information. Ask only for the medical information each law permits.
- Tracking. Count leave against each entitlement that applies, in the correct increment, and record why. Intermittent leave must be tracked in the smallest increment you use for other leave, and never more than one hour.
- Benefits and pay. Tell payroll and benefits on day one. Decide how paid leave runs with unpaid leave, how the employee’s share of health premiums will be collected, and whether a state program or disability plan is paying wage replacement.
- Return to work or next step. Restore the employee as the law requires. If the employee cannot return when leave ends, start the accommodation discussion before making any decision about employment. See what to do when employees exhaust their leave.

Who Does What: Managers and HR
Most leave requests reach a supervisor first, in conversation. That is where many claims begin, because a manager who says "we can’t spare you right now" or who asks for a diagnosis has already created a problem.
| Managers should | HR should |
|---|---|
| Recognize a possible leave or accommodation request | Decide which laws apply and whether the employee is eligible |
| Report it to HR the same day | Issue notices and request certification |
| Keep medical details out of team conversations and emails | Hold medical records in separate confidential files |
| Plan coverage for the work | Track time used and remaining |
| Refrain from approving, denying, or commenting on the reason | Approve, deny, and communicate the decision |
Our post on what managers should do when employees request leave gives a script.
Where Leave Management Goes Wrong
- Treating laws one at a time. Closing a file because FMLA leave ran out, without looking at the ADA, the PWFA, or state law.
- Late or missing notices. The FMLA deadlines are short, and a failure to give notice can itself be interference with the employee’s rights if it causes harm.
- Counting protected absences as attendance points. FMLA leave cannot be counted under a no-fault attendance policy. See no-fault attendance policies and protected leave.
- Inconsistent application. Two employees in the same situation should get the same answer. If they do not, you should be able to show why from the file.
- Thin records. The employer usually carries the burden of showing it met its duties. FMLA records must be kept for at least three years, and medical records must be kept confidential and apart from personnel files. See leave compliance documentation best practices.
- Acting on frustration. A decision to discipline or terminate someone shortly after protected leave should be reviewed by HR before it is made, with the reason documented and unrelated to the leave.

Building the Skill
Leave administration is learned case by case, and the cases that hurt are the ones that cross laws. The two-day Leave and Accommodation Management seminar is an advanced, instructor-led workshop on coordinating the ADA, FMLA, PWFA, USERRA, workers’ compensation, and related state laws. It is offered in person and by video conference and is built around case studies and interactive exercises.

Frequently Asked Questions
What is leave management in HR?
It is the policies, process, and records an employer uses to handle employee time away from work, from the first request through return. It includes deciding which laws apply, sending required notices, tracking time, coordinating pay and benefits, and managing the return to work.
Which laws apply to employee leave?
At the federal level, the FMLA, the ADA, the PWFA, and USERRA most often apply. State workers’ compensation laws apply to work injuries, and many states and cities add family, medical, and sick leave laws of their own. More than one can apply to the same absence.
Does an employee have to ask for FMLA leave by name?
No. The employee has to give enough information for the employer to determine that the leave may qualify. From that point, the employer is responsible for deciding whether the leave is FMLA leave and for giving notice.
What happens when an employee runs out of FMLA leave?
The FMLA right to job restoration ends when the entitlement is used up and the employee cannot return. Other laws may still apply. Additional leave or a change at work may be a reasonable accommodation under the ADA or the PWFA, and state law may give more time. Review those before making an employment decision.
Do small employers have to provide leave?
Often, yes. The FMLA generally covers private employers with 50 or more employees, but the ADA and the PWFA start at 15, USERRA has no size threshold, and state and local laws can reach smaller employers still.
Can paid leave and FMLA leave run at the same time?
Generally, yes. FMLA leave is unpaid, but an employee may choose, or the employer may require, that accrued paid leave run concurrently, under the terms of the employer’s normal paid leave policy. Different rules apply when a disability plan or workers’ compensation is paying wage replacement.
The Bottom Line
Leave management is one process applied to several laws. Take every request in through one door, test it against each law that could apply, send the notices on time, track accurately, and treat the end of one entitlement as the start of the next question.
