In most cases, you do not accrue PTO while on FMLA leave. Federal regulations say that unpaid FMLA leave does not have to count as credited service for benefit accrual, so employers generally are not required to keep adding to your PTO balance while you are out.1eCFR. 29 CFR 825.215 – Equivalent Position The real answer, though, depends on how your employer treats other unpaid leaves and what your own handbook promises.
Why Accrual Usually Stops
The Family and Medical Leave Act gives eligible employees up to 12 workweeks of unpaid, job-protected leave in a 12-month period for qualifying reasons like a serious health condition, the birth or placement of a child, or a family member’s medical needs.2U.S. Department of Labor. Fact Sheet #28: The Family and Medical Leave Act The operative word is unpaid. Most PTO policies tie accrual to hours worked or pay periods completed, and neither is happening while you are out.
The regulation is explicit: unpaid FMLA leave periods need not be treated as credited service for purposes of benefit accrual, vesting, or eligibility to participate in benefit plans.1eCFR. 29 CFR 825.215 – Equivalent Position If your policy runs on hours worked, the hours are not there. If it runs on pay periods completed, you are not completing them in the usual sense.
The Equal Treatment Rule
What FMLA does require is consistency. Your entitlement to benefits other than group health insurance during FMLA leave is determined by whatever policy your employer already has for employees on other forms of unpaid leave.3eCFR. 29 CFR 825.209 – Maintenance of Employee Benefits So if your company lets employees on a personal leave of absence keep accruing PTO, it has to extend that same benefit to employees on FMLA leave.
The flip side matters too. Your employer cannot single out FMLA leave for worse treatment than comparable unpaid leaves. Doing so counts as illegal interference with FMLA rights.4eCFR. 29 CFR Part 825 – The Family and Medical Leave Act of 1993 – Section 825.220
Here is where the practical answer meets the legal one. Many employers do not offer any other extended unpaid leave, so there is nothing to compare against. Their policy freezes accrual for everyone who is not actively working, and FMLA leave gets treated the same way. The outcome looks like an FMLA rule, but it is really a uniform-policy rule.
When PTO Might Keep Accruing
A few situations can flip the default.
The most common is an employer policy more generous than federal law requires. If your handbook, collective bargaining agreement, or employment contract guarantees PTO accrual during all leaves of absence, your employer is bound by that commitment. Federal regulations require employers to honor any benefit program that provides greater leave rights than the FMLA itself.5eCFR. 29 CFR Part 825 – The Family and Medical Leave Act of 1993 – Section 825.700 Read your handbook before assuming the accrual is gone.
State laws are the other wild card. More than a dozen states and the District of Columbia have enacted their own paid family and medical leave programs, and some of these carry different benefit-accrual provisions than the federal FMLA. Check your state’s rules rather than relying on federal law alone.
Salaried employees whose PTO accrues per pay period, rather than per hour worked, sit in a gray area. If the policy ties accrual to employment status and you remain on the payroll during FMLA leave, the language may support continued accrual. It comes down to how the formula is written.
Using PTO You Already Have to Get Paid During FMLA
Whether PTO accrues is one question. Whether you can spend the PTO you already have to get paid during FMLA leave is a separate one, and the answer is yes.
Under federal regulations, an employee can substitute accrued paid leave for otherwise unpaid FMLA leave. Substitute means the paid leave and FMLA leave run at the same time, so your 12-week FMLA clock and your PTO balance count down together.6eCFR. 29 CFR 825.207 – Substitution of Paid Leave You do not get 12 weeks of FMLA plus a separate stretch of PTO on top.
Your employer can also require you to burn through accrued paid leave during FMLA, even if you would rather save it. When an employer imposes that requirement, it has to inform you of any procedural steps under the paid leave policy.7eCFR. 29 CFR 825.300 – Employer Notice Requirements If your employer’s policy says nothing about mandatory substitution, the choice is yours.
Your Existing PTO Balance When You Return
Whatever PTO you had banked before your leave started has to be waiting for you when you come back. Federal regulations state that benefits accrued before leave began, including paid vacation and sick leave that was not substituted for FMLA leave, must be available on return.1eCFR. 29 CFR 825.215 – Equivalent Position
Your employer also cannot make you requalify for benefits you had before you left. All benefits must resume at the same levels that existed when your leave began, adjusted only for changes that affected the entire workforce while you were out.1eCFR. 29 CFR 825.215 – Equivalent Position If the company bumped everyone’s PTO allotment while you were out, you get that bump too. If nothing changed, your balance picks up where it left off, minus whatever you spent as paid leave during FMLA.
Document your accrued PTO balance before you leave. If a dispute comes up when you return, you will want the record.
If Your Employer Gets It Wrong
Employers who interfere with FMLA rights face real financial exposure. If you win an FMLA case, a court can award the wages, salary, and benefits you lost because of the violation, plus interest. The court then adds liquidated damages equal to the total of that lost compensation and interest, effectively doubling the payout, unless the employer can prove it acted in good faith and had reasonable grounds for believing it was not violating the law.8Office of the Law Revision Counsel. 29 USC 2617 – Enforcement
The court must also order the employer to pay your attorney’s fees, expert witness fees, and litigation costs. That fee-shifting makes FMLA cases viable for employees who could not otherwise afford counsel. Emotional distress and punitive damages are not available under the federal FMLA, though some state family leave laws allow them.
In the PTO context, a violation might look like this: your employer lets employees on personal leave keep accruing PTO but freezes accrual for anyone on FMLA leave. That disparate treatment is what the equal-treatment rule prohibits, and the lost PTO would count as denied benefits in a damages calculation.
Who These Rules Actually Cover
All of this only applies if you are actually eligible for FMLA. To qualify, you need to have worked for your employer for at least 12 months, logged at least 1,250 hours during the 12 months before your leave starts, and work at a location where your employer has at least 50 employees within 75 miles.2U.S. Department of Labor. Fact Sheet #28: The Family and Medical Leave Act If you do not meet all three requirements, FMLA does not apply, and your PTO accrual during any leave depends entirely on your employer’s policy and applicable state law.
