The Family and Medical Leave Act (FMLA): Who Qualifies and What It Covers

Twelve Weeks the Law Protects

Signed into law by President Bill Clinton on February 5, 1993, the Family and Medical Leave Act (FMLA) established a federal floor for job-protected leave in the United States. Before its passage, an employee could lose their job simply by needing to recover from surgery or care for a newborn. The law changed that dynamic — but only for workers and employers who meet its specific requirements.

FMLA is administered by the U.S. Department of Labor's Wage and Hour Division. It covers approximately 60 percent of American workers, though eligibility rules exclude a significant portion of the workforce.

Who Must Comply

FMLA coverage is not universal. It applies to three categories of employers:

• Private-sector employers with 50 or more employees within 75 miles of the work site
• All public agencies, regardless of size (federal, state, and local government)
• All public and private elementary and secondary schools, regardless of employee count

Small private businesses with fewer than 50 employees are exempt from FMLA. This is a significant gap: roughly 40 percent of private-sector workers are employed by businesses below the threshold.

Employee Eligibility Requirements

Even at a covered employer, individual employees must clear three hurdles to qualify:

1. Length of service: Worked for the employer for at least 12 months
2. Hours worked: Logged at least 1,250 hours during the 12 months preceding the leave
3. Work-site size: The employer must have at least 50 employees within 75 miles of the employee's work location

The 12 months of service need not be consecutive. Prior service with the same employer counts if the break was less than seven years, or resulted from military service or a collective bargaining agreement.

Qualifying Reasons for FMLA Leave

The statute specifies the conditions under which leave may be taken. Not every medical or family situation qualifies.

Defining a "Serious Health Condition"

The term "serious health condition" is a defined legal term — not every illness qualifies. Under 29 C.F.R. § 825.113, a serious health condition is an illness, injury, impairment, or physical or mental condition involving:

• Inpatient care in a hospital, hospice, or residential medical facility, or
• Continuing treatment by a health care provider (incapacity of more than three consecutive days plus follow-up visits, or a chronic condition requiring periodic treatments)

Common colds, flu, earaches, and routine dental work typically do not qualify unless complications arise. Pregnancy qualifies even before delivery because prenatal care involves continuing treatment.

How FMLA Leave Works in Practice

FMLA leave is unpaid at the federal level, though many states and employers layer paid leave on top. Employers may — and often do — require employees to use accrued paid leave concurrently with FMLA leave. This is legal and common.

Leave can be taken all at once or intermittently. Intermittent FMLA is a common source of workplace friction: an employee might take a few hours weekly for a chronic condition like migraines or rheumatoid arthritis. Employers cannot deny intermittent leave when medically necessary, but they may transfer the employee to an equivalent position better suited to intermittent scheduling.

Notice and Medical Certification

When leave is foreseeable, employees must provide at least 30 days' advance notice. For unforeseeable leave, notice must be given as soon as practicable — generally the same or next business day. Failure to provide timely notice can delay or deny leave.

Employers may require medical certification from a health care provider within 15 calendar days. The certification must confirm the serious health condition, its expected duration, and the need for leave. Employers may seek second and third opinions at their own expense.

Employee Protections

FMLA guarantees specific rights upon return from leave:

• Restoration to the same position or an equivalent position with the same pay, benefits, and working conditions
• Continuation of group health insurance on the same terms as if leave had not been taken
• Protection against interference, restraint, or denial of FMLA rights
• Protection against retaliation for exercising FMLA rights or opposing unlawful FMLA practices

Highly compensated "key employees" — salaried employees in the top 10% at the work site — may be denied restoration if reinstatement would cause substantial and grievous economic injury to the employer. This exception is narrow and rarely applied.
