Yes, your employer can deny your leave of absence, but only in defined situations. Whether an employer can lawfully deny a leave of absence depends on which law applies to your request, whether you meet its eligibility rules, and whether you followed the required notice and documentation steps. When no federal or state leave law covers your situation and no company policy grants the time, the decision is largely your employer’s to make.
When an Employer Can Legally Deny Leave
Most lawful denials fall into a handful of categories. If your situation fits one of them, your employer is generally on solid ground.
You Don’t Meet Eligibility Requirements
The Family and Medical Leave Act applies to public agencies, schools, and private companies with 50 or more employees. To qualify for its 12 workweeks of unpaid, job-protected leave, you must have worked for the employer for at least 12 months, logged at least 1,250 hours in the 12 months before leave starts, and work at a site with at least 50 employees within 75 miles.1U.S. Department of Labor. Fact Sheet 28 – The Family and Medical Leave Act Miss any one of those and your employer can deny FMLA leave. The employer must tell you within five business days of your request whether you’re eligible and, if not, why.2eCFR. 29 CFR 825.300 – Employer Notice Requirements
Your Reason Doesn’t Qualify
The FMLA covers a specific list of reasons: your own serious health condition; caring for a spouse, child, or parent (not parent-in-law) with a serious health condition; the birth or placement of a child; and qualifying needs tied to a family member’s military deployment.3U.S. Department of Labor. FMLA Frequently Asked Questions A request that falls outside those categories, such as leave to care for a parent-in-law, is not federally protected. Your state law may still cover it, but under federal law your employer can say no.
You’ve Already Used Your 12 Weeks
Once you’ve used all 12 workweeks of FMLA leave in a 12-month period, the employer is not required to grant more FMLA-protected leave until the next period begins.3U.S. Department of Labor. FMLA Frequently Asked Questions
You Didn’t Give Enough Notice
For foreseeable leave, such as a planned surgery or an expected due date, you must give at least 30 days’ advance notice. Without a good explanation for a shorter warning, the employer can delay or deny FMLA coverage. For unforeseeable situations, you’re expected to notify your employer the same day you learn of the need or the next business day.4eCFR. 29 CFR 825.302 – Employee Notice Requirements for Foreseeable FMLA Leave
You Didn’t Return Medical Certification
Your employer can require a medical certification from your healthcare provider to verify a serious health condition. You have 15 calendar days to submit the paperwork after the employer requests it. If the form is incomplete, the employer must give you seven days to fix it. If you still don’t produce adequate documentation, the employer can deny FMLA protection.5eCFR. 29 CFR 825.313 – Failure to Provide Certification Otherwise-valid claims collapse here more than anywhere else. Treat the 15-day window seriously.
Undue Hardship Under the ADA or PWFA
When you request leave as a reasonable accommodation for a disability under the Americans with Disabilities Act, or for a limitation related to pregnancy, childbirth, or a related medical condition under the Pregnant Workers Fairness Act, the employer can deny the request by showing undue hardship. That means significant difficulty or expense given the company’s size and resources, not ordinary inconvenience.6U.S. Equal Employment Opportunity Commission. Employer-Provided Leave and the Americans with Disabilities Act An employer also never has to grant indefinite leave where you can’t say whether or when you’ll return.
No Law and No Policy Covers You
If no federal or state leave law applies and your employer’s handbook or contract doesn’t guarantee the time, granting leave is discretionary. One caution: an employer who approves discretionary leave for some employees and denies identical requests from others risks a discrimination claim, and under the ADA employees with disabilities must have access to employer-provided leave on the same terms as everyone else.6U.S. Equal Employment Opportunity Commission. Employer-Provided Leave and the Americans with Disabilities Act Policies must be applied evenhandedly.
When Your Leave Is Protected
If you meet the coverage rules of one of the following laws, the employer cannot deny leave outright and the burden shifts onto them to justify any refusal.
The FMLA
Eligible employees get up to 12 workweeks of unpaid, job-protected leave in a 12-month period, with group health insurance continued on the same terms as if you were still working.3U.S. Department of Labor. FMLA Frequently Asked Questions When medically necessary, leave can be taken intermittently or as a reduced schedule, and the employer doesn’t get to veto that.7eCFR. 29 CFR 825.202 – Intermittent Leave or Reduced Leave Schedule The one exception is bonding time after the birth or placement of a healthy child, where intermittent leave requires employer agreement.
Military families get more. Up to 26 workweeks in a single 12-month period are available to care for a current servicemember or recent veteran with a serious injury or illness, and that entitlement extends beyond the usual immediate family to include next of kin.8eCFR. 29 CFR 825.127 – Leave to Care for a Covered Servicemember With a Serious Injury or Illness
The ADA
The ADA covers employers with 15 or more employees and treats leave as one possible reasonable accommodation for a disability. There’s no fixed number of weeks. You and your employer work out the length case by case through the interactive process, and the employer has to make a genuine effort to explore options rather than simply refusing.9U.S. Equal Employment Opportunity Commission. The ADA – Your Responsibilities as an Employer
The Pregnant Workers Fairness Act
Since June 2023, the PWFA has required employers with 15 or more employees to provide reasonable accommodations, including leave, for limitations related to pregnancy, childbirth, or related medical conditions. This fills a gap for pregnant workers who don’t qualify for FMLA leave because they haven’t worked long enough or their employer is too small.10U.S. Equal Employment Opportunity Commission. What You Should Know About the Pregnant Workers Fairness Act
State Laws
Many state laws go further than the FMLA. They frequently cover smaller employers that fall below the 50-employee threshold and often expand the definition of family member to include domestic partners, grandparents, siblings, and in-laws.11National Conference of State Legislatures. State Family and Medical Leave Laws Thirteen states and the District of Columbia also run paid family and medical leave programs funded by payroll contributions, with Delaware, Maine, Maryland, and Minnesota launching benefits in 2026. A request your employer can legally deny under federal law may still be protected under your state’s statute, so check the specific rules where you work.
Retaliation Is Separate From the Denial
Whether or not you were entitled to the leave, your employer cannot punish you for requesting it in good faith. Under the FMLA, the employer cannot fire, demote, cut hours, or take any other adverse action because you requested or took protected leave, and the same protection covers anyone who files a complaint or participates in an investigation.12Office of the Law Revision Counsel. 29 US Code 2615 – Prohibited Acts The ADA provides similar anti-retaliation protection for filing an EEOC charge.13U.S. Equal Employment Opportunity Commission. The ADA – Your Employment Rights as an Individual With a Disability Retaliation is a separate claim from the underlying denial.
What to Do If Your Leave Is Denied
Which path you take depends on which law you believe protected the request.
For an FMLA violation, you can file a complaint with the Wage and Hour Division of the U.S. Department of Labor in person, by phone, or by mail at any local WHD office. You can also skip the administrative route and file a private lawsuit in federal or state court. The deadline for a lawsuit is two years from the last violation, or three years if the violation was willful.14U.S. Department of Labor. FMLA Advisor – Enforcement of the FMLA
For an ADA or PWFA violation, file a charge of discrimination with the EEOC. The deadline is 180 days from the alleged discrimination, extending to 300 days if your state has its own anti-discrimination law covering disability, which most do. You can reach the EEOC at (800) 669-4000 or any field office.13U.S. Equal Employment Opportunity Commission. The ADA – Your Employment Rights as an Individual With a Disability
Document everything as it happens. Save your original leave request, any written denial, medical certifications you submitted, and any emails or messages about the situation. Employers who wrongly deny leave often claim the employee never followed proper procedures, and written records are the fastest way to counter that argument.
