Your US employer can deny FMLA leave — but only for specific, legally defined reasons. The Family and Medical Leave Act provides eligible employees with up to 12 weeks of unpaid, job-protected leave per year for qualifying reasons. If your employer denies it, they must have a valid basis under the law.

Key Takeaways

  • FMLA denial is lawful if you do not meet eligibility criteria — 12 months of service, 1,250 hours worked, and a covered employer (50+ employees within 75 miles).
  • Denial is also lawful if your condition does not qualify as a serious health condition under the FMLA regulations.
  • Failure to provide sufficient certification is the most common reason for legitimate denial.
  • Your employer cannot deny FMLA for retaliatory reasons — that is a violation of the Act.
  • You have the right to reinstatement after FMLA leave — with limited exceptions for key employees at the highest pay levels.

Valid Reasons for Denial

An employer can lawfully deny FMLA leave in these situations:

You do not meet eligibility requirements. You must have worked for the employer for at least 12 months (not necessarily consecutive), worked at least 1,250 hours in the preceding 12 months, and work at a location where the employer has at least 50 employees within 75 miles.

Your condition does not qualify. Not every illness qualifies for FMLA. Your condition must be a “serious health condition” — defined as an illness, injury, impairment, or physical or mental condition that involves inpatient care or continuing treatment by a healthcare provider. Minor illnesses (colds, flu, stomach upsets) do not qualify, even if you miss work.

You have exhausted your 12-week entitlement. FMLA provides 12 workweeks per 12-month period. Once you have used it, your employer has no obligation to grant additional FMLA leave.

You failed to provide timely certification. If your employer asks for medical certification and you do not provide it within 15 calendar days (or a reasonable extension), your leave may be denied.

You did not provide sufficient notice. For foreseeable leave (such as planned medical treatment), you must give at least 30 days’ notice. For unforeseeable leave, you must notify your employer as soon as practicable.

When Denial Is Illegal

Denial of FMLA leave is illegal if:

  • You meet all eligibility requirements and your condition qualifies
  • The denial is retaliatory — because you previously took FMLA leave or opposed an unlawful practice
  • The denial is based on discriminatory reasons — race, gender, disability, or another protected characteristic
  • The employer interferes with your rights — for example, by discouraging you from applying or misrepresenting your entitlement
  • The employer counts the wrong 12-month period — they must use a consistent, disclosed method (calendar year, rolling, or other)

How to Respond to a Denial

If your FMLA leave is denied:

  1. Ask for the reason in writing — the employer should provide a specific basis
  2. Check your eligibility — confirm your hours, tenure, and worksite
  3. Review the certification — if the denial is based on insufficient documentation, ask what is missing
  4. Request a corrected certification — your doctor may need to provide more detail
  5. File a complaint — with the Wage and Hour Division of the Department of Labor
  6. Consult an attorney — FMLA violations can result in lost wages, benefits, and reinstatement

FAQ

Can my employer deny FMLA because I have too many absences?

No. The FMLA is separate from an employer’s attendance policy. Your employer cannot count FMLA-protected absences in their attendance points system — and cannot deny FMLA because you have exceeded some internal absence threshold.

Can my employer deny intermittent FMLA leave?

Intermittent FMLA leave can be denied if the medical certification does not support the need for intermittent leave. If the certification is sufficient, your employer must allow intermittent leave — but they can require you to transfer to an equivalent position that better accommodates the schedule.

Can my employer deny FMLA because I used it for a different reason last year?

Each qualifying reason for FMLA is separate. If you used FMLA for maternity leave, you are still entitled to FMLA later in the same 12-month period for a different qualifying reason — up to the total 12-week limit.

What is a “key employee” exception?

Employers can deny reinstatement to “key employees” — those among the highest-paid 10% of employees within 75 miles — if reinstatement would cause substantial and grievous economic injury to the employer. However, they cannot deny the leave itself — only reinstatement after leave.

Can I appeal a denied FMLA claim?

Internally, yes — ask for a review by HR or a higher manager. Externally, you can file a complaint with the DOL or file a private lawsuit. The statute of limitations is 2 years (3 years for willful violations).
