FMLA (Family and Medical Leave Act): Quick Definition

The Family and Medical Leave Act (FMLA) is a US federal law that gives eligible employees up to 12 weeks of unpaid, job-protected leave per year for specific family and medical reasons. Enacted in 1993, FMLA ensures that workers do not lose their jobs or employer-sponsored health coverage when they need time off for serious health conditions, family caregiving, or the arrival of a new child.

For HR teams, FMLA compliance is non-negotiable. Violations can trigger Department of Labour investigations, back-pay awards, and lawsuits. Understanding eligibility rules, qualifying events, and employer obligations protects both your employees and your organisation.

Key Takeaways

• FMLA provides up to 12 weeks of unpaid, job-protected leave per 12-month period.
• Employees must have worked for the employer for at least 12 months and logged 1,250+ hours in the preceding 12 months.
• Covered employers include private-sector companies with 50+ employees and all public agencies.
• Leave can be taken intermittently, and employer-sponsored health coverage must continue during FMLA leave.

What Is FMLA?

The Family and Medical Leave Act is a federal statute administered by the US Department of Labour’s Wage and Hour Division. It requires covered employers to provide eligible employees with:

• Up to 12 weeks of unpaid, job-protected leave during a 12-month period.
• Continuation of group health insurance coverage during the leave on the same terms as if the employee had continued working.
• Restoration to the same or an equivalent position upon return from leave.

FMLA applies to all public agencies, public and private elementary and secondary schools, and private-sector employers with 50 or more employees within a 75-mile radius. Roughly 56% of US employees work for employers covered by FMLA.

Who Is Eligible for FMLA Leave?

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

1. Employment duration — The employee has worked for the employer for at least 12 consecutive months.
2. Hours worked — The employee has logged at least 1,250 hours of service during the 12-month period immediately preceding the leave.
3. Employer coverage — The employer has 50 or more employees within a 75-mile radius of the employee’s worksite.

Employees on intermittent leave or reduced schedules still accumulate hours. The 12-month period can be defined by the employer as a calendar year, a fixed 12-month period (e.g., fiscal year), a rolling 12-month period, or a rolling forward 12-month period — as long as the method is applied consistently.

Qualifying Reasons for FMLA Leave

FMLA covers leave for the following purposes:

Qualifying Reason	Maximum Leave
Serious health condition of the employee	12 weeks
Caring for a spouse, child, or parent with a serious health condition	12 weeks
Birth and care of a newborn child	12 weeks
Placement of a child for adoption or foster care	12 weeks
Qualifying exigency arising from a family member’s military service	12 weeks
Care for a covered servicemember with a serious injury or illness (spouse, parent, child, or next of kin)	26 weeks

A “serious health condition” is defined as an illness, injury, impairment, or physical or mental condition that involves either inpatient care or continuing treatment by a healthcare provider. Common examples include cancer, chronic conditions requiring ongoing treatment, and conditions that render an employee incapacitated for more than three consecutive days.

FMLA Pay and Benefits

FMLA leave is unpaid. However, several financial protections apply:

• Health insurance continuation — The employer must maintain group health insurance coverage on the same terms as during active employment. If the employee would have paid a portion of premiums, the employee continues to owe that share.
• Accrued paid leave — Employers may require or allow employees to substitute accrued paid leave (vacation, sick, personal) for unpaid FMLA leave. This is often called “stacking.”
• State paid leave programs — Many states offer paid family or medical leave that runs concurrently with FMLA. States like California, New York, New Jersey, and Washington have active programmes that provide partial wage replacement during FMLA-qualifying leave.

Employer Obligations Under FMLA

Covered employers have specific responsibilities:

1. Post required notices. Display the official Department of Labour FMLA poster in a conspicuous location where employees can see it. Employers with remote workers must provide electronic or mail copies.
2. Respond to leave requests within five business days. When an employee requests FMLA leave or when the employer has enough information to determine the leave may qualify, the employer must notify the employee of eligibility and rights and responsibilities within five business days.
3. Designate qualifying leave as FMLA leave. The employer must designate leave as FMLA-qualifying and notify the employee of the amount of leave counted against the 12-week entitlement.
4. Maintain records. Keep FMLA-related records for at least three years, including payroll records, employee requests, notices, and health insurance documentation.
5. Avoid interference or retaliation. Employers cannot discourage employees from taking FMLA leave, count FMLA leave against employees in performance reviews, or terminate employees for exercising FMLA rights.

FMLA vs State Leave Laws

Several states have leave laws that exceed FMLA protections:

Factor	FMLA (Federal)	California CFRA	New York Paid Family Leave
Employer size	50+ employees	5+ employees	All private employers
Paid or unpaid	Unpaid	Unpaid (PFL provides partial pay)	Partial pay (up to 67% of wages)
Duration	12 weeks	12 weeks	12 weeks
Own serious health condition	Yes	Yes	No (only family care)

Employees may be entitled to leave under both FMLA and state law simultaneously, with state law filling gaps where FMLA does not apply — particularly for smaller employers.

Frequently Asked Questions

Does FMLA leave have to be taken all at once?

No. FMLA leave can be taken intermittently — in separate blocks — or on a reduced schedule when medically necessary. For example, an employee recovering from surgery might take three days per week for six weeks. The employer must allow intermittent leave for the employee’s own serious health condition or to care for a family member with a serious health condition, provided it is medically necessary.

Can an employee be fired while on FMLA leave?

No. FMLA prohibits retaliation and interference. An employer cannot terminate an employee for taking or requesting FMLA leave. However, an employer can terminate an employee during FMLA leave if the termination would have occurred regardless — such as during a documented layoff planned before the leave began.

What happens to my health insurance during FMLA leave?

Your employer must continue your group health insurance coverage on the same terms as if you were actively working. If you were paying a share of premiums, you must continue paying that share. If you fail to pay your share, the employer may still maintain coverage but can recover the unpaid portion from you upon your return.

Does FMLA apply to part-time employees?

Yes, if the employee meets the eligibility requirements: 12 months of employment and 1,250 hours worked in the preceding 12 months. Part-time employees who work a consistent schedule can accumulate the required hours, though those working very few hours per week may not reach the 1,250-hour threshold within 12 months.

How does FMLA interact with state paid family leave programmes?

In states with paid family leave programmes (such as California, New York, New Jersey, and Washington), paid leave runs concurrently with FMLA when both apply. The employee receives partial wage replacement from the state programme while FMLA protects their job. Employees may still owe the unpaid balance of FMLA leave if the state programme covers fewer weeks than FMLA provides.
