Family and Medical Leave Act (FMLA)

The Family and Medical Leave Act (FMLA) gives eligible employees of covered employers up to 12 workweeks of unpaid, job-protected leave in a defined 12-month period for a set list of family and medical reasons. A separate entitlement of up to 26 workweeks applies to military caregiver leave.

During FMLA leave the employer must maintain the employee's group health coverage on the same terms as if the employee were still working, and at the end of the leave the employee is generally restored to the same or an equivalent job.

Coverage and eligibility are two different tests

An employer is covered if it is a private employer that had 50 or more employees on the payroll in 20 or more workweeks in the current or preceding calendar year. Public agencies and schools are covered without regard to size.

An employee at a covered employer is eligible only if all three of the following are true on the date the leave starts: the employee has been employed by that employer for at least 12 months, the employee worked at least 1,250 hours in the 12 months immediately before the leave, and the employee works at a worksite where the employer has 50 or more employees within a 75-mile radius.

The 12 months of employment do not have to be consecutive. The 1,250 hours are hours actually worked, so paid time off, holidays, and prior leave do not count toward the threshold. The 50-in-75 test is measured from the employee's worksite, which is why a remote employee is generally assigned to the site they report to rather than to their home address.

Qualifying reasons and how much leave each one carries

All FMLA leave draws from the same 12-week bank in the employer's chosen 12-month period, except military caregiver leave, which has its own larger entitlement.

What job protection actually means

• Restoration to the same position or an equivalent one with equivalent pay, benefits, and other terms and conditions of employment.
• Continuation of group health coverage on the same terms, with the employee still responsible for their share of the premium.
• No loss of any employment benefit accrued before the leave began.
• No interference with, restraint of, or denial of the exercise of FMLA rights, and no retaliation for taking leave.
• Leave taken does not have to be paid, but an employer may require, and an employee may elect, to run accrued paid leave concurrently with FMLA.

Where leave administration goes wrong

Most FMLA problems are administrative rather than substantive. The leave was owed, and the paperwork or the clock is what failed.

• Never choosing a 12-month method. The regulations allow a calendar year, any fixed 12-month year, a period measured forward from first use, or a rolling 12 months measured backward. If the employer does not select and apply one consistently, the method most favorable to the employee applies.
• Waiting for the employee to say "FMLA". The obligation to designate leave starts when the employer has enough information to know the absence may be FMLA qualifying, whatever words the employee used.
• Missing the notice clock. The employer generally has five business days to provide the eligibility and rights and responsibilities notice, and five business days after receiving enough information to provide the designation notice.
• Failing to designate. Leave that qualifies must be designated and counted against the entitlement. Declining to designate does not preserve goodwill, it extends the exposure.
• Mishandling intermittent leave. Increments must follow the employer's normal timekeeping increment, and the employer cannot require the employee to take more leave than needed.
• Treating certification as optional or as unlimited. Certification may be requested, recertification is allowed on defined intervals, and second and third opinions have rules attached.
• Letting health premiums lapse. If the employee's share is not collected during unpaid leave, coverage and the recovery of those premiums both become messy.

Why it matters operationally

FMLA turns an absence into a tracked case with dates, documents, and deadlines attached. The employers that handle it well are the ones that centralize the intake, run the notice clocks automatically, keep medical certifications out of the personnel file, and can reconstruct a year later exactly what was designated, when, and on what basis.

It also drives real staffing decisions. A 12-week protected absence, or an intermittent schedule spread across months, changes coverage planning, backfill budgets, and how performance is evaluated for the period.
