It depends on your employer's policy and, increasingly, on your state. No single federal rule decides it. The Family and Medical Leave Act guarantees eligible new parents 12 weeks of unpaid, job-protected leave, but it never forces you to spend paid time off during that stretch.
That gap matters the moment you start planning around your due date. A policy that requires you to use up all your PTO can drain a balance you were counting on for later. Whether you have a real choice often comes down to your state. As of a count FindLaw's overview cites, at least 13 states and Washington, D.C. already run paid family leave programs, and more states have joined since. Where one of those programs exists, it can replace part of your wages without ever touching your PTO bank.

Nothing here replaces personal advice from your HR department, your payroll provider, or an employment attorney licensed in your state.
The Federal Baseline: What FMLA Guarantees
The federal starting point for maternity leave is the Family and Medical Leave Act, commonly called FMLA. It grants eligible employees up to 12 weeks of unpaid leave in a 12-month period for the birth of a child. It also guarantees the same or an equivalent job when you return. FMLA leave protects your group health insurance too, though you must keep paying your share of the premium while you're out.
Not every worker qualifies, and not every employer must comply. FMLA often covers employees at workplaces with 50 or more employees within 75 miles. It also requires the employee to have worked for that employer for at least 12 months. On top of that, it requires at least 1,250 hours logged in the year before leave starts.
Miss any one of those three thresholds, and FMLA's unpaid, job-protected leave does not apply to your job. Your employer's own policy might still cover the gap. Your state's law might too. Check your own start date, your hours worked, and your worksite's headcount before you assume anything.
FMLA itself never tells your employer whether you must spend your PTO during those 12 weeks. The statute leaves that call to company policy. One company can let you save every accrued hour. Another can require you to burn through vacation, sick, and personal time before the unpaid clock even starts.
Gusto's guidance for employers states that a company can often require staff to use up their PTO balance during FMLA leave. That guidance comes from an HR vendor, not a court. Confirm with your own HR team how your employer applies it. Ask HR which category your own employer's policy falls into before you make a leave plan.
Gusto explains one exception worth knowing, again as vendor guidance rather than a court ruling. If you keep receiving a paid benefit, such as employer-paid health coverage, during your leave, some employers treat that stretch as partially paid. That can change whether PTO substitution is even allowed. Ask HR, in writing, which weeks of your leave count as paid and which do not.
Does My State Change the Answer?
Federal law sets a floor, not a ceiling. States are free to require more than FMLA does. A growing number of states run their own paid family and medical leave programs, funded through small payroll taxes. These programs pay you a percentage of your wages while you are out for the birth or adoption of a child, and that changes the practical answer to whether you must use PTO, because a real paycheck may arrive whether or not you touch your PTO balance.
As of a count cited in FindLaw's overview, at least 13 states and Washington, D.C. already ran paid family leave programs, and more states have added programs since that count. California, New York, New Jersey, Rhode Island, Washington, Colorado, Massachusetts, Connecticut, Oregon, Maryland, and Delaware are among the states commonly cited as running an active program, though the list keeps growing, so confirm your own state's current status directly. Benefit amounts, wait periods, and maximum weeks differ sharply from state to state. Some programs pay close to full wages for a period, and others cap out well below that, so the dollar impact of skipping your PTO depends only on which state you work in.
If you live in a state without a paid program, your paycheck during leave depends only on your employer, and some employers pay part or all of your salary through short-term disability coverage. For state-sponsored short-term disability programs specifically, FindLaw explains that benefits often run one-half to two-thirds of wages for four to 12 weeks, with about six weeks typical for an uncomplicated delivery. A private, employer-sponsored plan can replace a different share of wages for a different length of time, so check your own plan documents rather than assuming this range applies. Where no state program and no employer-paid disability benefit exist, PTO is often your only paid option, and that is the scenario where employers are most likely to require you to use it.
Even inside a single state, city and county rules can add another layer. Some cities require extra sick-leave accrual or add local paid-leave benefits on top of the state program. A state-level search alone can miss a local rule that applies to your specific job. Always check your city or county labor office alongside your state agency to be sure.
The Pregnancy Discrimination Act and Your Right to Equal Treatment
Separate from FMLA, the Pregnancy Discrimination Act amends federal civil rights law. It bars employers from treating pregnancy, childbirth, and related medical conditions worse than any other short-term medical condition. Say your employer lets someone recovering from knee surgery keep some PTO choice. That same employer then forces every new parent to drain their balance first.
Federal anti-discrimination law treats that mismatch as the kind of unequal treatment the Pregnancy Discrimination Act targets. The rule is about consistency. It is not about giving pregnant employees extra PTO protections beyond what any similar medical leave would receive. Equal treatment, not extra treatment, is the standard the law sets.
A newer law adds another layer. The Pregnant Workers Fairness Act took effect on June 27, 2023. It is a separate law from FMLA. The EEOC issued its final regulation carrying out the law on April 15, 2024.
It requires covered employers to provide reasonable accommodations for pregnancy, childbirth, and related medical conditions. This applies unless doing so would cause undue hardship. That can include an adjusted schedule or extra unpaid time beyond what FMLA alone would provide. This accommodation duty sits on top of, not instead of, your FMLA rights.
For PTO specifically, the practical takeaway is narrower than many readers expect. Neither the PDA nor the PWFA hands pregnant employees an automatic right to keep every PTO hour. Both laws do prohibit one thing, though: singling pregnancy out for a harsher PTO rule. The rule your employer applies to a similar disability or medical leave has to match.
If you suspect your employer is treating maternity leave less favorably than other leave, raise it with HR in writing first. If it goes unresolved, the EEOC's Q&A guidance explains how to escalate a charge to the agency. Keep dated notes of any policy difference you notice. Specifics matter more than a general impression.
Filing a charge with the EEOC carries a strict deadline, often 180 days from the discriminatory act. That window can extend to 300 days in states with their own fair-employment agency. Missing it can permanently bar the claim, so if you believe you were treated unfairly, don't wait until after your leave ends to ask a lawyer whether your clock is already running. An employment attorney can often review the facts for free in a first meeting.
Which Situation Applies to You?
The honest answer to whether you must use PTO depends on three questions. Does FMLA cover your job at all? Does your state run a paid-leave program? These questions come first, before any policy detail.
What does your employer's handbook say? Match your situation to one of the four scenarios below. That scenario shows which rule controls your leave. Each one assumes leave for the birth of a child, since the same logic applies to most parental leave.

Your Employer Requires PTO to Run Concurrently With FMLA
Many employers, especially larger ones, write a required-PTO rule directly into the leave policy. You must use every accrued vacation, sick, and personal day before or during unpaid FMLA leave. If that describes your handbook, your PTO balance and your unpaid leave run at the same time, so the accrued hours simply convert your first few weeks from unpaid to paid. Gusto's guidance confirms employers can often set this rule, as long as they apply it consistently to every employee on similar leave.
Ask HR how many PTO hours you will have left when you return. A required-PTO policy can leave your bank at zero the day you come back. If you also live in a paid-leave state, ask whether that state benefit runs alongside PTO or only after it is gone, because the order changes your total income. Request the answer in writing, so you have a record if the practice ever changes mid-leave.
Your Employer Allows PTO But Doesn't Require It
Some employers leave the choice to you. You can spend PTO to stay paid during part of your leave, or save it and take the rest of your FMLA leave unpaid. This flexibility often favors employees who plan to take extended time later, such as for a second procedure or a phased return to work. Before you decide, calculate how many weeks of pay your current balance buys, since a vague sense of "a few weeks left" is not the same as counting the hours.
A common approach is a hybrid plan. Use enough PTO to cover the first two or three weeks after delivery, when costs spike and recovery is hardest to predict, then switch to unpaid leave once that period passes. This preserves some PTO for a pediatrician visit or a sick day after you return. Whatever split you choose, confirm with payroll how PTO usage shows up on each paycheck.
You Live in a State With Paid Family Leave
If your state runs a paid family leave program, that benefit can replace part of your wages without touching your PTO balance. The payment often comes from a state fund, not your employer's payroll. Wage replacement can run close to full pay for lower earners, or a smaller percentage for higher earners, and most programs cap the weekly benefit at a set dollar maximum. Some employers still require or encourage using PTO to cover the waiting period before state benefits start, often about one week.
Apply directly with your state's paid-leave agency well before your due date. Processing can take one to several weeks, and benefits are not always retroactive to the first day of leave. Coordinate the paperwork with HR, because your employer often needs to confirm your employment and wage history so the state can calculate your benefit. Keeping PTO in reserve while state benefits cover your core paycheck is often the strategy that leaves you the most flexibility later.
Your Employer Is Too Small for FMLA Coverage
If your employer has fewer than 50 employees within 75 miles, FMLA's unpaid, job-protected leave does not apply to your job, no matter how long you've worked there. That doesn't necessarily mean zero protection. Some states extend pregnancy-disability or family-leave rules to smaller employers than the federal threshold covers. Without FMLA in the picture, your job security during leave rests only on your employer's own policy and, where one exists, your state law.
In this situation, PTO often becomes your only source of income during leave. That makes your balance size far more important than it would be under FMLA. Ask your employer directly, in writing, whether your position will be held open and whether PTO use is required, optional, or simply undefined. An undefined policy is a request waiting to happen, so propose your own plan in writing and get agreement before your leave starts.
Worked Example: Turning 80 Hours of PTO Into Paid Weeks
Here is how the numbers work for one common case. Sarah earns $24 an hour, works a standard 40-hour week, and has accrued 80 hours of PTO by her due date. Her employer is FMLA-covered, and her state has no paid family leave program. That leaves her with two paycheck options during leave: PTO, and, if she qualifies, short-term disability.
| Detail | Amount |
|---|---|
| Total FMLA leave | 12 weeks (480 hours unpaid baseline) |
| Accrued PTO balance | 80 hours |
| Hourly wage | $24.00 |
| PTO converted to paid weeks | 2 weeks |
| Weeks paid via PTO | 2 of 12 |
| Weeks unpaid without other benefits | 10 of 12 |
| Gross pay from PTO | $1,920 |
At 80 accrued hours, Sarah's PTO covers two full 40-hour weeks of her 12-week leave. That pays out $1,920 in gross wages ($24 x 80 hours) before taxes. The remaining 10 of her 12 weeks stay unpaid. She can close some of that gap only if she qualifies for short-term disability through an employer or private plan, since her state offers no public wage-replacement program.
Spreading the 80 hours across all 12 weeks, instead of using them up front, would not create more total pay. It would soften the drop in each paycheck rather than fully replacing two weeks and then stopping. This math is a simplified model of a real paycheck, since it skips taxes, benefit deductions, and any employer top-up your own company might offer. It also assumes PTO pays your regular hourly rate, which is standard but not universal, so confirm your plan's payout rule before you count on this pattern.
Layering in a second benefit changes the picture further. Say Sarah's employer also offers short-term disability paying 60% of wages for six weeks. Six of her ten unpaid weeks would then pay at $14.40 an hour instead of $0, adding roughly $3,456 in disability income on top of her $1,920 in PTO pay. Running both numbers before her leave starts shows Sarah her real household budget instead of a guess, which is why this kind of math is worth doing early.
How PTO Played Out for Three New Parents
The federal and state rules above play out differently depending on where you work and live. These three employees faced the same core question: whether to use PTO during maternity leave. Their employer policies, states, and company sizes pointed them toward different answers. Each example teaches a lesson worth checking against your own situation.
Maria: State Paid Leave Preserved Her PTO Balance
Maria works as a marketing manager in California. The state's paid family leave program pays a percentage of wages for up to eight weeks, funded through payroll contributions rather than her employer directly. Her company requires new parents to use one week of PTO to cover the state program's initial waiting period, then lets state benefits take over. Because Maria planned ahead, she kept most of her 120 accrued PTO hours untouched, saving them for her return to work and her baby's first pediatrician visits.
| Week of leave | Pay source |
|---|---|
| Week 1 | PTO (employer-required waiting period) |
| Weeks 2-8 | California state paid family leave |
| Weeks 9-12 | Unpaid FMLA, unless extended by disability leave |
Maria's case shows the upside of a paid-leave state. Her employer's required-PTO rule only touched one week instead of twelve, because the state program did the heavy lifting after that. Workers in a state without a paid-leave program don't get that backstop. That gap is a major reason the answer to this question varies so much from one new parent's story to another.
Devon: No FMLA Coverage Meant PTO Was His Only Paycheck
Devon works at a 38-person marketing agency in Texas, a state with no paid family leave program. His employer has fewer than 50 employees, so FMLA's unpaid, job-protected leave never applied to his paternity leave. Job security and pay were only up to company policy. His employer's handbook was silent on parental leave beyond the standard PTO policy, so Devon had to negotiate his own arrangement directly with his manager.
With 96 hours of PTO banked, Devon covered a little over two weeks of pay before switching to unpaid time. His manager agreed in writing to hold his position for four total weeks. Devon's biggest misconception going in was assuming FMLA automatically applied to any full-time job, a mistake that could have cost him his position had his manager been less accommodating. His story is a reminder that below the 50-employee threshold, PTO rules, job protection, and leave length all depend on what your employer agrees to in writing.
Priya: A Mandatory-Exhaustion Policy in a State Without Paid Leave
Priya works for a 200-employee insurance firm in Ohio, which has no state paid family leave program. Her employer's handbook requires every employee taking FMLA leave, for any medical reason, to use up all accrued PTO before the unpaid clock starts. HR confirmed the same rule applies to short-term disability leave for a broken leg or major surgery. Because the policy applied equally across leave types, it met the Pregnancy Discrimination Act's equal-treatment standard, even though it still drained her entire 88-hour PTO balance.
| PTO hours available | Weeks of paid leave |
|---|---|
| 88 hours (Priya's balance) | 2.2 weeks |
| 0 hours remaining | 9.8 weeks unpaid |
Priya's lesson differs from Maria's and Devon's. The required-PTO rule itself was lawful, because it applied equally to everyone, but that fairness didn't make the 12 weeks any more affordable. She supplemented her income by filing for short-term disability through her employer's voluntary plan, which paid 60% of her wage for six weeks after a standard delivery. Reading her plan documents before her due date, instead of after, gave her enough lead time to file the claim without a gap in pay.
Mistakes to Avoid
- Assuming FMLA automatically applies. Employees at small companies who assume federal job protection exists often discover only during leave that their employer has fewer than 50 employees nearby, leaving them without the reinstatement right they expected.
- Never reading the PTO section of the handbook before getting pregnant. Waiting until the third trimester to check the policy leaves less time to save additional PTO hours or negotiate an alternative arrangement with HR.
- Assuming state paid leave replaces 100% of wages. Most state programs cap the weekly benefit and replace a percentage of pay, not the full amount, so budgeting as though the check will match a normal paycheck can create a real shortfall.
- Skipping a written confirmation from HR. A verbal answer about whether PTO use is required can change once a different manager or HR representative handles the paperwork, leaving no record to point to.
- Forgetting to ask how PTO affects health insurance premiums. Some employers only continue subsidizing coverage while an employee is receiving pay through PTO, so once PTO runs out, the employee can be billed the full premium unexpectedly.
- Applying for state paid leave too late. Processing delays of one to several weeks are common, and applying only after the baby arrives can create a real gap between the end of employer pay and the start of the state benefit.
- Confusing short-term disability with paid family leave. They cover different things and sometimes run at different times, and treating them as interchangeable can leave a week or more completely unpaid.
- Not checking whether PTO continues to accrue during leave. Some employers stop PTO accrual once leave becomes unpaid, so an employee who assumed a normal accrual rate can return to a smaller balance than expected.
Do's, Don'ts, Pros, and Cons of Using PTO During Leave
Do
- Do read your full PTO and leave policy before you're pregnant or as soon as you know, so you're not learning the rules for the first time during a stressful week.
- Do ask HR in writing whether PTO use is required, optional, or undefined, since a written answer protects you if the practice gets applied inconsistently later.
- Do check your state's paid family leave eligibility months before your due date, because processing takes time and early filing avoids a payment gap.
- Do calculate how many weeks your PTO balance buys at your real hourly or salary rate, rather than guessing from a vague sense of "a lot of days."
- Do ask whether PTO continues to accrue while you're on leave, since the answer changes how much balance you will have when you return.
- Do talk to a payroll or HR contact about how PTO usage will appear on each paycheck, so a mid-leave surprise doesn't catch you off guard.
Don't
- Don't assume your state has no paid leave program without checking, since several states have started programs in only the last few years.
- Don't wait until your due date to ask HR how PTO interacts with FMLA, because questions like accrual and health-premium billing can take weeks to answer.
- Don't spend all your PTO in the first two weeks without a plan for the rest of your leave, unless you have already confirmed another income source for later weeks.
- Don't assume a coworker's experience with PTO and leave applies to you, since policies can differ by department, hire date, or a since-changed handbook.
- Don't skip reading the fine print on short-term disability, because waiting periods and percentage-of-wage caps vary widely between plans.
- Don't forget to ask what happens to your PTO accrual rate if you switch from full-time to a reduced schedule after returning.
Pros
- Keeps your paycheck closer to normal. A paid week during leave matters most for households whose budget assumes a full salary.
- Keeps benefits active without a lapse. Payroll continues running as usual while you're on PTO, so premium deductions and contributions process normally.
- Buys flexibility for later. Spending PTO early can let you extend unpaid leave afterward if recovery or childcare arrangements take longer than planned.
- Can preserve retirement contributions. Some employer retirement plans only count paid weeks toward matching contributions, so PTO-covered weeks keep contributing to that total.
- Gives you some control over timing. Where PTO is optional, you decide which weeks get paid instead of accepting a default that might not fit your situation.
Cons
- Drains a balance you may need later. PTO spent during leave is not available for a sick day, family emergency, or vacation once you return.
- Can mask a true unpaid-leave shortfall. A paycheck that looks normal during PTO weeks can create a false sense of security about the unpaid weeks still ahead.
- Required-PTO policies remove your choice. If your employer requires PTO use, you cannot save the balance for a moment you might need it more.
- State benefits can be smaller than your regular pay. Delaying a state paid-leave application while using PTO first can hide the fact that the state benefit replaces less than your PTO did.
- PTO payouts do not always match your regular schedule. Some employers pay PTO at a flat rate that ignores shift differentials or bonuses, which can lower your paycheck even while "fully paid."
What to Do Next Before Your Leave Starts
Work through these steps in order, starting as soon as you suspect you're pregnant or plan to grow your family:
- Read your employee handbook's PTO, leave, and short-term disability sections in full, and note anything unclear.
- Ask HR, in writing, whether PTO use is required, optional, or undefined during FMLA leave.
- Confirm whether your employer meets FMLA's size and coverage thresholds, and whether you meet the tenure and hours requirements.
- Check your state's paid family leave program for eligibility, benefit amount, and how far in advance you can apply.
- Calculate how many weeks your current PTO balance covers at your real pay rate.
- Decide, with input from HR, how you want to sequence PTO, state benefits, and unpaid weeks.
- Contact an employment attorney or your state labor agency if you believe your employer is treating your leave less favorably than similar medical leave.
Frequently Asked Questions
Can my employer fire me for refusing to use PTO during FMLA leave?
Generally, no. If your leave qualifies under FMLA, your employer cannot retaliate against you for how you use protected leave. The company can still require PTO substitution under its own written policy. Document any pressure and raise it with HR in writing.
Does using PTO count toward FMLA's 12-week limit?
No. FMLA's 12-week limit measures time away from work, not how that time is paid. Using PTO during part of your leave does not extend the total 12 weeks. It only changes whether those weeks are paid or unpaid.
What happens to unused PTO if I don't use it during leave?
It depends on your employer's payout policy. Some states require employers to pay out accrued, unused PTO when employment ends. During active employment, whether unused PTO carries over, caps, or expires is a matter of company policy.
Can I use PTO and short-term disability at the same time?
Usually not for the same hours. Most short-term disability plans reduce or deny benefits for any period already paid through PTO. The plan replaces lost wages rather than adding to full pay. Ask your plan administrator before combining the two.
Does maternity leave have to be paid?
No, not under federal law. FMLA guarantees unpaid, job-protected leave, and no federal statute requires private employers to pay wages during that leave. Some states and some employer policies do provide paid leave. The real answer depends on where you live and work.
How much PTO do most employers require before maternity leave starts?
There is no single standard. Some employers require none, some require a partial balance, and others require every accrued hour before unpaid leave begins. The exact number depends only on your employer's written policy, not on any federal rule.
Can part-time employees use PTO during parental leave?
Yes, if the PTO policy covers part-time staff. Part-time employees often accrue PTO at a prorated rate. Whether that time can be used during parental leave follows the same company policy that applies to full-time staff. FMLA eligibility, though, often requires 1,250 hours worked.
What if my employer has no written PTO policy at all?
Ask HR to clarify in writing before you rely on any assumption. Without a documented policy, practice can vary employee to employee. That variation risks unequal treatment under federal anti-discrimination law. A written answer protects you if the informal practice changes later.
Can I negotiate a longer leave than FMLA provides?
Yes, in many cases. FMLA sets a floor of 12 weeks, not a ceiling. Employers can voluntarily offer longer leave, and some do as a benefit. Ask HR whether extended leave, paid or unpaid, is available beyond the federal minimum.
Does adoption leave follow the same PTO rules as birth leave?
Largely, yes. FMLA covers leave for the placement of an adopted or foster child on the same terms as leave for a birth. Most employer PTO and leave policies apply the identical rule to both situations.
What happens to my health insurance if I run out of PTO and FMLA leave?
Your employer's obligation to continue coverage often ends with your FMLA leave, not your PTO. After FMLA leave ends, continued coverage typically shifts to COBRA or your employer's standard leave-of-absence policy. Ask HR about that exact transition point.
Is short-term disability the same as paid family leave?
No, they are different benefits. Short-term disability typically covers your own medical recovery from childbirth. Paid family leave programs often cover bonding time with a new child instead. Some states or employers offer both back-to-back for a longer combined paid period.
