FMLA Leave: 12 Weeks Unpaid Leave Rights & Employer Obligations

Quick Answer: What Is FMLA Leave?

The Family and Medical Leave Act (FMLA) is a federal law enacted in 1993 that provides eligible employees with up to 12 workweeks of unpaid, job-protected leave per 12-month period for specified family and medical reasons. During FMLA leave, employers must maintain the employee's group health insurance coverage under the same terms as if they had continued working.

The FMLA also provides 26 workweeks of leave in a single 12-month period for military caregiver leave (caring for a covered servicemember with a serious injury or illness).

Employer Coverage: Which Employers Are Subject to FMLA?

The FMLA applies to:

• Private-sector employers with 50 or more employees in 20 or more workweeks in the current or preceding calendar year
• All public agencies (state, local, and federal government), regardless of the number of employees
• All public and private elementary and secondary schools, regardless of the number of employees

The 50-Employee Threshold

The 50-employee count includes:

• All employees on the payroll, including part-time and temporary workers
• Employees on leave of any kind (paid or unpaid)
• Joint employees and employees of related entities in some circumstances

Once an employer reaches 50 employees and triggers FMLA coverage, they remain a covered employer for the remainder of that calendar year and the following calendar year, even if headcount drops below 50.

Employee Eligibility: Who Can Take FMLA Leave?

To be eligible for FMLA leave, an employee must meet all three requirements:

1. Employer Requirement

The employee works for a covered employer (50+ employees for private sector).

2. Tenure Requirement

The employee has worked for the employer for at least 12 months. The 12 months do not need to be consecutive -- a break in service of up to 7 years can be bridged (longer breaks are bridged if the break was due to military service or was governed by a collective bargaining agreement).

3. Hours Requirement

The employee has worked at least 1,250 hours during the 12-month period immediately preceding the start of leave. This averages to approximately 24 hours per week.

4. Worksite Requirement

The employee works at a location where the employer has at least 50 employees within a 75-mile radius. This means an employee at a small remote office may not be eligible even if the overall company employs thousands.

Special Rules for Airline Flight Crew

Airline flight crew employees have a modified hours requirement: they must have worked or been paid for at least 60% of the applicable total monthly guarantee (or its equivalent) AND must have worked or been paid for at least 504 hours (not counting personal commute time or vacation, medical, or sick leave).

Qualifying Reasons for FMLA Leave

Eligible employees may take FMLA leave for the following reasons:

1. Serious Health Condition (Employee's Own)

A serious health condition is an illness, injury, impairment, or physical or mental condition that involves either:

• Inpatient care: An overnight stay in a hospital, hospice, or residential medical care facility, including any period of incapacity or subsequent treatment in connection with the stay
• Continuing treatment by a health care provider, which includes:
  • A period of incapacity of more than 3 consecutive full calendar days plus two or more treatments by a health care provider (or one treatment plus a continuing regimen)
  • Any period of incapacity due to pregnancy or prenatal care
  • Any period of incapacity or treatment for a chronic serious health condition (e.g., asthma, diabetes, epilepsy)
  • A period of incapacity that is permanent or long-term due to a condition for which treatment may not be effective (e.g., Alzheimer's, terminal cancer)
  • Any period of absence for multiple treatments for a condition that would likely result in incapacity of more than 3 days if not treated (e.g., chemotherapy, physical therapy, dialysis)

Common conditions that do not typically qualify include colds, flu (unless complications arise), earaches, upset stomach, minor ulcers, headaches (other than migraines), and routine dental or orthodontic problems.

2. Birth and Bonding

• The birth of a child and to bond with the newborn within 12 months of birth
• Both mothers and fathers are eligible for bonding leave

3. Placement for Adoption or Foster Care

• The placement of a child for adoption or foster care and to bond with the newly placed child within 12 months of placement

4. Care for a Family Member

To care for a spouse, child, or parent (but not parent-in-law) with a serious health condition. "Child" includes a biological, adopted, or foster child, a stepchild, a legal ward, or a child of a person standing in loco parentis who is either under 18 or an adult child incapable of self-care because of a mental or physical disability.

5. Qualifying Exigency (Military Families)

For a qualifying exigency arising from the foreign deployment of a spouse, child, or parent who is a member of the Armed Forces (including the National Guard and Reserves). Qualifying exigencies include:

• Short-notice deployment (7 or fewer days notice)
• Military events and related activities
• Childcare and school activities
• Financial and legal arrangements
• Counseling
• Rest and recuperation (up to 15 days per instance)
• Post-deployment activities (up to 90 days after deployment ends)
• Parental care when the military member's parent is incapable of self-care

6. Military Caregiver Leave (26 Weeks)

To care for a covered servicemember (spouse, child, parent, or next of kin) with a serious injury or illness incurred in the line of active duty. This provides up to 26 workweeks of leave in a single 12-month period -- this is the only FMLA provision that exceeds 12 weeks.

Intermittent Leave and Reduced Schedule Leave

FMLA leave does not have to be taken all at once. Employees may take leave:

Intermittent Leave

Leave taken in separate blocks of time for a single qualifying reason. For example, an employee undergoing chemotherapy might take leave for treatment every other Friday.

Reduced Schedule Leave

A reduction in the usual number of working hours per workday or workweek. For example, an employee recovering from surgery might work 6-hour days instead of 8-hour days for several weeks.

Rules for Intermittent/Reduced Schedule Leave

• For serious health conditions: Available when medically necessary. The employee does not need employer approval for the intermittent schedule, but the employer may require certification
• For bonding leave (birth, adoption, foster care): Available only with employer agreement. Employers can refuse intermittent bonding leave
• Transfer to an equivalent position: If intermittent leave is foreseeable and based on planned medical treatment, the employer may temporarily transfer the employee to an alternative position that better accommodates the recurring leave, provided the position has equivalent pay and benefits
• Minimum increment: Employers cannot require employees to take more FMLA leave than necessary. The minimum increment should generally be no more than one hour (or the shortest period the employer's payroll system uses to track attendance)

Employer Notice Requirements

General Notice

Every covered employer must display the FMLA poster (WH-1420) in a conspicuous place where employees and applicants can see it. If the employer has any eligible employees, this information must also be included in the employee handbook or other written guidance.

Eligibility Notice

Within 5 business days of an employee requesting leave or the employer learning that leave may be FMLA-qualifying, the employer must notify the employee whether they are eligible for FMLA leave. If not eligible, the notice must state at least one reason why.

Rights and Responsibilities Notice

Along with the eligibility notice, the employer must provide a Rights and Responsibilities notice informing the employee of:

• Specific expectations and obligations
• Any requirement to provide medical certification
• The employee's right to substitute paid leave
• Whether the employer requires fitness-for-duty certification before returning
• Whether the employee is a "key employee" who may not be restored

Designation Notice

Within 5 business days of having enough information to determine whether leave qualifies as FMLA leave, the employer must provide a Designation Notice informing the employee:

• Whether the leave is designated as FMLA leave
• The amount of leave counted against the entitlement (if known)
• Whether the employer requires a fitness-for-duty certification to return to work
• Whether a substitute paid leave will run concurrently

---

Medical Certification

Employers may require employees to provide a medical certification from a health care provider to support a request for FMLA leave due to a serious health condition. The DOL provides optional forms:

• WH-380-E: Certification of Health Care Provider for Employee's Serious Health Condition
• WH-380-F: Certification of Health Care Provider for Family Member's Serious Health Condition

Certification Rules

• The employer must allow at least 15 calendar days for the employee to provide certification
• If certification is incomplete or insufficient, the employer must advise the employee in writing what additional information is needed and allow 7 calendar days to cure the deficiency
• The employer may contact the health care provider for authentication or clarification only through HR personnel, a leave administrator, or a management official -- never the employee's direct supervisor

Second and Third Opinions

If the employer has reason to doubt the validity of the initial certification:

1. The employer may require a second opinion at the employer's expense from a health care provider of the employer's choosing (who is not regularly employed by the employer)
2. If the second opinion conflicts with the first, the employer may require a third opinion at the employer's expense from a provider jointly agreed upon by both parties
3. The third opinion is final and binding

Recertification

For leave taken for a chronic or long-term condition, employers may request recertification every 30 days in connection with an absence (unless the initial certification specifies a longer minimum duration of the condition).

Returning from FMLA Leave

Job Restoration

Upon returning from FMLA leave, an employee must be restored to:

• The same position they held before leave, OR
• An equivalent position with equivalent pay, benefits, and other terms and conditions of employment

"Equivalent" means virtually identical in terms of pay, schedule, working conditions, and location. The position must involve the same or substantially similar duties and responsibilities.

Fitness-for-Duty Certification

Employers may require a fitness-for-duty certification before allowing an employee to return from leave taken for their own serious health condition. The employer must notify the employee of this requirement in the Rights and Responsibilities notice provided at the start of leave. The certification must be from the employee's health care provider and must certify that the employee is able to resume work. The employer may require that it specifically address the employee's ability to perform essential functions of the job (the employer must provide a list of essential functions).

Key Employee Exception

A key employee is a salaried FMLA-eligible employee who is among the highest-paid 10% of all employees within 75 miles. An employer may deny job restoration (but not the leave itself) to a key employee if:

• Restoration would cause substantial and grievous economic injury to the employer's operations
• The employer notifies the employee of their key employee status when leave is requested
• The employer notifies the employee when it determines restoration will be denied
• The employee is given a reasonable opportunity to return to work after receiving notice

Interaction with Paid Leave and Other Laws

Substitution of Paid Leave

Employers may require (or employees may elect) to substitute accrued paid leave (vacation, sick, PTO) for unpaid FMLA leave. When paid leave is substituted, the employer must follow both the paid leave policy and FMLA requirements simultaneously. The FMLA leave and paid leave run concurrently, not consecutively.

Workers' Compensation

When an employee's workers' compensation absence also qualifies as FMLA leave, the employer may designate the absence as FMLA leave running concurrently with workers' compensation leave.

ADA Interaction

The Americans with Disabilities Act (ADA) and the FMLA overlap but serve different purposes:

• FMLA provides a fixed amount of leave (12 weeks) with job restoration rights
• ADA may require additional unpaid leave as a reasonable accommodation beyond the 12-week FMLA period
• When an employee exhausts FMLA leave but cannot return to work, the employer must consider whether additional leave is a reasonable accommodation under the ADA before taking adverse action

State FMLA Laws

Many states have enacted their own family and medical leave laws that provide greater protections than federal FMLA. When state and federal laws apply simultaneously, the employee is entitled to the more generous provision. Notable state laws include:

These state programs are typically paid (funded through payroll taxes or employee contributions), unlike federal FMLA which is unpaid.
