In 2025, employers and employees across the U.S. continue to rely on the FMLA leave requirements under the federal Family and Medical Leave Act. This guide delves into the employee eligibility requirements, covered employers, leave duration, qualifying reasons, and the vital responsibilities of employers. It also highlights the latest guidance from the Department of Labor on coordinating with state paid leave laws and offers real‑world examples.


What Is FMLA Leave Requirements

The Family and Medical Leave Act (FMLA) provides eligible employees with job‑protected unpaid leave for qualifying medical and family reasons. It ensures continued group health insurance coverage during such leave Although the federal law does not mandate paid leave, state-paid family and medical leave (PFML) programs can supplement pay during FMLA leave 


 Who Is Eligible

✅ Employee Eligibility Requirements

To qualify for FMLA leave, an employee must meet all three key criteria:

  • Twelve months of cumulative employment (not necessarily consecutive; excluding service gaps over seven years except for certain exceptions)
  • 1,250 hours worked in the 12 months before leave—roughly 24–25 hours weekly 
  • Employment at a worksite with at least 50 employees within 75 miles 

Flight crew and airline staff follow special rules involving monthly guarantees and hours worked 

✅ Covered Employers

FMLA applies to:

  • Private-sector employers with 50+ employees working ≥20 weeks in the current or previous year
  • Public agencies, federal/state/local, any size
  • Public and private educational institutions, any size 

Affiliated businesses may be considered a single employer under integrated/joint‑employer rules 


Leave Entitlement & Duration

12‑Week Standard Leave

Eligible employees may take 12 weeks of FMLA leave within a 12‑month period for qualifying reasons 

The 12‑month window is measured based on the first use of leave, continuing for one year. Unused weeks do not carry over until the 12‑month period ends.

Servicemember Caregiver Leave

Up to 26 weeks of leave may be granted in a single 12‑month period to care for a covered servicemember with a serious injury or illness.


Qualifying Reasons for FMLA Leave 🩺

FMLA leave is available for:

  • Birth, adoption, or foster care placement and bonding
  • Serious health conditions impacting the employee
  • Care for an employee’s spouse, child, or parent with serious health conditions
  • Qualifying exigency leave related to active-duty family members
  • Military caregiver leave for grievously injured servicemembers 

“Serious health condition” includes inpatient care, chronic or acute condition needing ongoing treatment (e.g., cancer, diabetes).


 Intermittent & Reduced‑Schedule Leave

Employees may take FMLA on an intermittent basis or reduced‑schedule when medically necessary. For birth/adoption bonding, intermittent leave needs employer mutual agreement Leave tracking must be precise—employers often convert hours/days proportionately for part-time or nonstandard schedules .


 Notice, Medical Certification & Substitution

a) Notice Requirements

  • Known leave: employees should give 30 days advance notice
  • Unforeseen leave: “as soon as practicable” after learning of the need 

b) Medical Certification

Employers may request medical certification to justify leave, and employees must fulfill certification deadlines .

c) Substitution of Paid Leave

Employees may elect, or employers may require, substitution of accrued paid leave (sick, vacation) during FMLA. However, when receiving state PFML benefits or workers’ comp/disability pay, employers cannot force substitution without consent 


 Job & Health Benefits Protection

FMLA ensures the following protections:

  • Job restoration: Return to the same or equivalent position
  • Health insurance: Continuation on original terms
  • Anti‑retaliation: Employers cannot penalize or interfere with an employee’s FMLA rights 

Coordination with State Paid Leave Programs

PFML Laws in 2025

As of 2025, 13 states + D.C. (e.g., CA, CO, CT, DE, MA, MD, MN, NJ, NY, OR, RI, WA, DC) offer paid family and medical leave 

Employees may receive partial wage replacement during FMLA leave if state PFML applies 

DOL Guidance on Interoperability

On January 14, 2025, the DOL clarified that employers cannot require employees to use accrued paid leave while receiving PFML compensation, mirroring rules on disability pay Employers can only require substitution by mutual agreement. Employers must also designate such leave properly as FMLA


Employer Responsibilities

a) Posting & Notice

  • Must post FMLA notice in visible areas
  • Provide written eligibility notice within five business days of an FMLA‑qualifying event or educational request

b) Record‑keeping & Confidentiality

  • Track all forms of leave accurately
  • Maintain medical records confidentiality under FMLA/HIPAA

c) Integrated & Joint‑Employer Coverage

  • Review workplace structure; affiliated entities may be joint employers requiring combined employee counts

 Monitoring & Compliance in 2025

  • Stay current with state PFML program rollouts (e.g., DE starts 2026, MN in 2026) 
  • Update leave policies and handbooks to reflect FMLA and state law changes
  • Use modern tracking tools that accurately log intermittent leave
  • Conduct training for HR and management on FMLA rights/responsibilities
