What Is the Family and Medical Leave Act (FMLA)?
Key Takeaways
- ✓The FMLA provides eligible employees up to 12 weeks of unpaid, job-protected leave per 12-month period for the birth or placement of a child, a serious health condition, or caring for a family member with a serious health condition.
- ✓It applies to private employers with 50 or more employees within a 75-mile radius, all public agencies, and all public and private elementary and secondary schools.
- ✓To be eligible, an employee must have worked for the employer for at least 12 months, logged at least 1,250 hours during the 12 months before leave begins, and work at a location where the employer has 50+ employees within 75 miles.
- ✓Only about 56% of US workers are actually eligible for FMLA leave because many work for small employers, haven't met the tenure requirement, or haven't reached the 1,250-hour threshold (DOL, 2023).
- ✓FMLA violations are the most common subject of complaint calls to the DOL's Wage and Hour Division, and interference and retaliation claims generate significant litigation for employers (DOL, 2024).
The FMLA was a recognition that workers sometimes face medical and family situations that demand their time and attention, and they shouldn't have to choose between their job and their family. Before 1993, there was no federal protection. An employer could legally fire someone for taking time off to have a baby, care for a dying parent, or recover from surgery. The law provides the leave, but it doesn't pay for it. FMLA leave is unpaid unless the employer has a policy providing paid leave or the employee is covered by a state paid family leave program. Employers can require (and most do require) employees to use accrued PTO, sick leave, or vacation time concurrently with FMLA leave. The practical challenge for HR teams isn't understanding that FMLA leave exists. It's administering it correctly. FMLA administration involves eligibility determinations, notice requirements, medical certification, intermittent leave tracking, benefits continuation, reinstatement rights, and documentation at every step. Getting any of these wrong can turn a routine leave request into a lawsuit.
FMLA Eligibility Requirements
Three conditions must be met for an employee to be eligible for FMLA leave. All three are required.
Employer coverage
Private employers are covered if they employ 50 or more employees in 20 or more workweeks in the current or preceding calendar year. The 50-employee count includes all employees on the payroll, including part-time, temporary, and employees on leave. Public agencies (federal, state, local government) and public and private elementary and secondary schools are covered regardless of size.
Employee eligibility
The employee must have worked for the employer for at least 12 months (doesn't have to be consecutive; any employment within the past seven years typically counts). The employee must have worked at least 1,250 hours during the 12 months immediately before the leave begins. That's roughly 24 hours per week. And the employee must work at a location where the employer has at least 50 employees within a 75-mile radius. That last requirement means an employee at a small satellite office may not be eligible even if the company has thousands of employees elsewhere.
Airline crew exception
For airline flight crew employees, the hours-of-service requirement is different: they must have worked or been paid for at least 60% of the applicable monthly guarantee and at least 504 hours during the previous 12 months (not including personal commute time or vacation, medical, or sick leave). This special rule recognizes the unique scheduling patterns in the airline industry.
Qualifying Reasons for FMLA Leave
Not every absence qualifies for FMLA protection. The law specifies five categories of qualifying reasons.
| Qualifying Reason | Leave Available | Who Can Take It | Key Details |
|---|---|---|---|
| Birth of a child and bonding | 12 weeks | Mother or father | Must be taken within 12 months of birth, both parents can take leave simultaneously if they work for the same employer (limited to 12 weeks combined for bonding only) |
| Placement of child for adoption or foster care | 12 weeks | Adoptive or foster parent | Same 12-month window as birth; includes pre-placement activities if required by the adoption/foster care agency or court |
| Serious health condition of the employee | 12 weeks | The employee | Inpatient care, incapacity of 3+ consecutive days with treatment, chronic conditions, pregnancy, permanent/long-term conditions |
| Serious health condition of a family member | 12 weeks | Spouse, child, or parent (not in-laws, siblings, grandparents, or domestic partners unless covered by state law) | Same definition of serious health condition; leave to care for the family member, not just be present |
| Military qualifying exigency | 12 weeks | Spouse, child, or parent of covered military member | Short-notice deployment, military events, childcare, financial/legal, counseling, rest and recuperation, post-deployment activities |
| Military caregiver leave | 26 weeks in a single 12-month period | Spouse, child, parent, or next of kin of covered servicemember | Care for servicemember with serious injury or illness; this 26-week entitlement is a one-time, per-servicemember, per-injury benefit |
Employer Obligations Under the FMLA
The FMLA creates detailed obligations for employers at every stage of the leave process.
Notice obligations
Employers must post the FMLA general notice in a conspicuous location and include FMLA information in the employee handbook. When an employee requests leave or the employer learns of a potentially qualifying reason, the employer must provide two written notices: (1) an eligibility/rights and responsibilities notice within 5 business days telling the employee whether they're eligible and what's expected, and (2) a designation notice within 5 business days of having enough information to determine if the leave qualifies, telling the employee whether the leave is FMLA-protected.
Medical certification
Employers can require employees to provide a medical certification from a healthcare provider supporting the need for FMLA leave. The employer must allow at least 15 calendar days for the employee to provide the certification. If the certification is incomplete or insufficient, the employer must give the employee 7 days to cure deficiencies. The employer can contact the healthcare provider for clarification or authentication (but only through HR, not the employee's direct supervisor). The employer can require a second opinion at the employer's expense and a third opinion (also at the employer's expense) if the first two disagree.
Benefits continuation
Employers must maintain the employee's group health insurance coverage during FMLA leave on the same terms as if the employee hadn't taken leave. The employee remains responsible for their share of premiums. If the employee doesn't return from leave for a reason other than the continuation of a serious health condition or a circumstance beyond their control, the employer can recover its share of the health insurance premiums paid during the leave.
Reinstatement rights
When the employee returns from FMLA leave, the employer must restore them to the same position or an equivalent position with the same pay, benefits, and terms and conditions of employment. An equivalent position must have the same shift, schedule, geographic location (commuting distance), and duties. The employer can't take the employee's return as an opportunity to restructure their role, reduce their authority, or eliminate their position (unless the elimination would have occurred anyway for legitimate business reasons unrelated to the leave).
Intermittent and Reduced Schedule FMLA Leave
Intermittent leave is the most administratively challenging aspect of FMLA compliance. It allows employees to take leave in separate blocks of time rather than one continuous period.
When intermittent leave applies
Employees can take FMLA leave intermittently (in separate blocks) or on a reduced schedule (reducing normal weekly or daily hours) when medically necessary for a serious health condition. Common examples include chemotherapy sessions, dialysis treatments, chronic migraine episodes, physical therapy appointments, and mental health treatment. For bonding with a newborn or newly placed child, intermittent leave is available only if the employer agrees. The employer doesn't have to approve intermittent bonding leave.
Tracking intermittent leave
The FLSA's FMLA regulations require employers to track intermittent leave in increments no greater than the smallest increment the employer uses to track other forms of leave, with a maximum increment of one hour. If your time system tracks in 15-minute increments, you can track FMLA in 15-minute increments. Accurate tracking requires a reliable timekeeping system and manager compliance in recording FMLA absences. Many organizations use dedicated leave management software (AbsenceSoft, LeaveLogic, FMLASource) to track intermittent leave rather than relying on payroll systems.
Employer rights during intermittent leave
The employer can temporarily transfer an employee on intermittent or reduced schedule leave to an available alternative position with equivalent pay and benefits that better accommodates the recurring periods of leave. The employer can also require the employee to use accrued paid leave (PTO, sick leave, vacation) concurrently with FMLA leave. If intermittent leave for planned medical treatment is foreseeable, the employer can require the employee to make a reasonable effort to schedule treatment so it doesn't unduly disrupt operations.
FMLA Interference and Retaliation
The FMLA prohibits two types of employer misconduct, and both generate significant litigation.
Interference
FMLA interference occurs when an employer prevents or discourages an employee from exercising FMLA rights. Examples include denying a valid FMLA request, failing to provide required notices, counting FMLA absences as attendance violations, requiring employees to find their own coverage before taking leave, discouraging employees from requesting leave, or failing to restore the employee to an equivalent position. The employee doesn't need to prove intent. If the employer's action interfered with FMLA rights, that's enough.
Retaliation
FMLA retaliation occurs when an employer takes an adverse action against an employee because they took or requested FMLA leave. Termination during or shortly after FMLA leave is the most obvious example, but retaliation also includes demotion, reduced hours, negative performance reviews timed to coincide with leave, exclusion from projects or opportunities, and hostile treatment upon return. Courts look at timing (adverse action shortly after FMLA leave is suspicious), comments by supervisors expressing frustration about the leave, and departures from normal employer practices.
State FMLA and Paid Leave Programs
Many states have family and medical leave laws that exceed the federal FMLA in coverage, duration, or benefits.
| State | Program Name | Key Difference from Federal FMLA |
|---|---|---|
| California | California Family Rights Act (CFRA) + Paid Family Leave (PFL) | Covers employers with 5+ employees. PFL provides up to 8 weeks at 60-70% pay |
| New York | Paid Family Leave (NY PFL) | 12 weeks at 67% of average weekly wage (capped). Covers bonding, family care, military qualifying exigency |
| Washington | Paid Family and Medical Leave (PFML) | 12 weeks family leave + 12 weeks medical leave (combined 16-week max). Up to 90% wage replacement |
| Massachusetts | Paid Family and Medical Leave (PFML) | 12 weeks family leave, 20 weeks personal medical leave. Up to 80% wage replacement |
| Colorado | FAMLI | 12 weeks at up to 90% of wages. Covers employers of all sizes. Funded by 0.9% payroll tax |
| Oregon | Paid Leave Oregon | 12 weeks (14 for pregnancy-related conditions). 100% wage replacement up to cap for low earners |
| Connecticut | CT Paid Leave | 12 weeks at up to 95% of minimum wage workers' pay, decreasing tiers for higher earners |
| New Jersey | Family Leave Insurance (FLI) | 12 weeks for bonding/family care at 85% of average weekly wage (capped) |
