In most cases, yes — an employer can revoke PTO after approving it. No federal law requires paid time off in the first place, so once it’s offered, the approval generally functions as a scheduling decision the employer can change rather than a promise you can enforce. The important exceptions are an employment contract or handbook that limits revocation, protected leave under the FMLA or ADA, a union contract, and state laws that treat accrued PTO as earned wages.
The Default Rule
The Fair Labor Standards Act does not require employers to provide vacation, sick leave, or any other paid time off. The Department of Labor treats those benefits as “matters of agreement between an employer and an employee.”1U.S. Department of Labor. Vacation Leave Because no federal statute mandates PTO, no federal statute controls how it’s managed once granted. A common misconception is that the FLSA forces employers to follow their own PTO policies. It doesn’t. The FLSA covers wages and overtime, not voluntary benefits.
Most American workers are also employed at will, meaning either side can change the terms of the working relationship at any time for any lawful reason. Approval of a vacation request, under that default, is closer to a tentative schedule than a binding commitment. Unless something specific constrains the employer, pulling back that approval is legal even when it’s costly and frustrating for you. The exceptions are where the real answer lives.
What Your Contract or Handbook Says
If you have a written employment contract that addresses PTO, its terms control. Some agreements grant specific leave entitlements or limit when the employer can cancel approved time off. If the contract says PTO can only be revoked in defined circumstances and the employer ignores that, you may have a breach of contract claim.
Employee handbooks and written policies matter too, even without a formal contract. If the handbook lays out a PTO approval process and doesn’t reserve a right to revoke, an employee who relied on that process has a reasonable argument that the employer is bound to honor it. Employers who deviate from their own written policies tend to fare poorly when disputes reach court. Most jurisdictions also recognize an implied duty of good faith, so an employer who routinely approves PTO and then yanks it back at the last minute to punish employees or dodge staffing costs may cross a line even when the policy is silent.
Read your handbook and any signed agreement first. That single document usually determines whether you have leverage or not.
Leave That Cannot Be Revoked
Some approved leave carries federal protection that overrides your employer’s general PTO policy. If your time off falls into one of these categories, revoking it isn’t just unfair — it’s unlawful.
FMLA Leave
The Family and Medical Leave Act entitles eligible employees at covered employers to up to 12 weeks of unpaid, job-protected leave per year for qualifying reasons like a serious health condition, caring for a family member, or the birth of a child. Federal law makes it unlawful for any employer to “interfere with, restrain, or deny” the exercise of FMLA rights.2Office of the Law Revision Counsel. 29 USC 2615 – Prohibited Acts Revoking previously approved FMLA leave is a textbook example of interference.
The federal regulations go further, defining interference to include discouraging an employee from using FMLA leave and any manipulation by the employer to avoid its responsibilities under the law.3eCFR. 29 CFR 825.220 – Protection for Employees Who Request Leave or Otherwise Assert FMLA Rights Operational excuses do not create an exception.
ADA Accommodation Leave
Leave can also qualify as a reasonable accommodation under the Americans with Disabilities Act. Covered employers must make reasonable accommodations to the known limitations of a qualified employee with a disability, unless doing so would impose an undue hardship on the business.4Office of the Law Revision Counsel. 42 USC 12112 – Discrimination Once leave is approved as an accommodation, the employer must hold the position open during the leave. The employer can substitute a different on-the-job accommodation that eliminates the need for leave, but it cannot simply cancel the approved accommodation without offering an effective alternative.5U.S. Equal Employment Opportunity Commission. Enforcement Guidance on Reasonable Accommodation and Undue Hardship Under the ADA
If You’re Covered by a Union Contract
Collective bargaining agreements sharply narrow an employer’s ability to revoke approved PTO. Vacation time is a mandatory subject of bargaining under the National Labor Relations Act, so the employer and union must negotiate it and the employer cannot unilaterally change the terms.6National Labor Relations Board. Employer/Union Rights and Obligations A unilateral change is itself evidence of bad faith bargaining.
Most CBAs include a grievance procedure for exactly this kind of dispute, and unresolved grievances typically move to arbitration. The NLRB may also get involved when the employer’s action amounts to a refusal to honor the bargaining agreement.7National Labor Relations Board. Collective Bargaining – Section 8(d) and 8(b)(3) Contact your steward quickly, because grievance timelines are short.
States That Treat PTO as Earned Wages
Several states classify accrued vacation as earned wages, which means the employer cannot simply take it away once it’s been earned. These states generally require employers to pay out unused vacation when the employment relationship ends and prohibit “use-it-or-lose-it” policies that force employees to forfeit accrued time.1U.S. Department of Labor. Vacation Leave
In those states, revoking approved time off carries extra risk. If an employee loses the ability to use earned PTO because the employer rescinded it, the employer may need to reschedule the time or compensate the employee for it. The specifics vary. Some states require written notice before any changes to PTO policies; others impose fines and back-pay liability on employers who fail to honor earned vacation. A revocation that’s legal in one state can violate wage law in another.
When Revocation Is More Defensible
Not every revocation is fair game to challenge. Some reasons hold up better than others, and employers who can document a genuine justification are harder to beat.
Urgent Operational Needs
A workload spike, the sudden loss of key staff, or a real emergency can leave an employer legitimately needing everyone on deck. Courts and regulators view those revocations more sympathetically when the employer gave reasonable notice, looked at alternatives before canceling anyone’s leave, and offered to reschedule. An employer who waits until the day before your flight is on much shakier ground than one who gives you two weeks and helps you rebook.
Fraud or Misrepresentation
If you got the PTO approved by lying — a fabricated family emergency, a fake doctor’s note, misrepresented dates — the employer has strong grounds to revoke. The employer should still investigate before acting, and outcomes typically depend on the severity of the dishonesty and existing disciplinary policies.
Policy Violations
Many employers set blackout periods during peak seasons or require minimum advance notice. If you got approval without disclosing that the dates fell during a blackout, or bypassed the normal approval chain, the employer may have grounds to cancel. Enforceability depends on whether the policies were clearly communicated and consistently applied. Selective enforcement aimed at particular employees invites discrimination claims.
Recovering Money You Already Spent
The financial hit from revoked PTO often isn’t the lost day but the non-refundable flights, hotels, and event tickets you booked. The legal doctrine of promissory estoppel may let you recover those costs. You generally need to show that the employer made a clear promise (the PTO approval), that you reasonably relied on it by spending money, and that enforcing the promise is the only fair result. Courts have recognized this kind of claim in employment cases where an employee took concrete financial steps based on an employer’s commitment.
Practically, many employers will reimburse cancellation costs voluntarily rather than risk a lawsuit or lose an employee’s trust. If yours won’t, small claims court is worth considering. Filing fees are modest and you typically don’t need an attorney. Keep every receipt, confirmation email, and cancellation notice. Good documentation turns a he-said-she-said into a clean damages calculation.
Retaliation if You Push Back
Objecting to a PTO revocation can feel risky. Federal protection depends on why the PTO was pulled. If the revocation is tied to discrimination, filing a complaint is protected activity under EEO laws, and the EEOC has stated that employers cannot punish employees for asserting their rights.8U.S. Equal Employment Opportunity Commission. Retaliation For FMLA-related disputes, the statute itself prohibits retaliation against employees who assert their rights or participate in FMLA proceedings.2Office of the Law Revision Counsel. 29 USC 2615 – Prohibited Acts
For ordinary PTO disputes with no discrimination or protected-leave angle, federal anti-retaliation law offers less. Your protection comes mainly from your contract, company policy, and state law. Employers remain free to discipline or terminate workers for legitimate, non-retaliatory reasons, so the line between lawful management and unlawful retaliation often turns on timing and documentation.8U.S. Equal Employment Opportunity Commission. Retaliation
What to Do Right Now
Start with your handbook, employment contract, and any written PTO policy. Look for language on revocation, blackout periods, and the company’s obligations once leave is approved. Silence on revocation works in your favor. Save a copy of the current policy so you have it if the language gets updated later.
Document everything. Save the original approval email or a screenshot, the revocation notice, and any conversations about the change. If the revocation was verbal, send a follow-up email confirming what was said: “I want to confirm our conversation today, in which you informed me that my approved PTO for [dates] has been revoked because [reason].” That paper trail matters if the dispute escalates.
Raise the issue internally first. Talk to your manager, then HR. Many companies have formal grievance procedures, and using them shows good faith. If you’re in a union, contact your steward immediately.
If internal resolution fails and you believe the revocation violates your contract, a protected-leave statute, or anti-discrimination law, consult an employment attorney. Many offer free initial consultations, and employment law varies enough by jurisdiction that generic advice only goes so far. For smaller losses like non-refundable travel, small claims may be more practical than hiring a lawyer. For discrimination-related claims, you can file a charge with the EEOC or your state’s equivalent agency without an attorney.8U.S. Equal Employment Opportunity Commission. Retaliation
