FMLA in Plain Language — Who Qualifies, What's Covered, and What Your Employer Must Do

The Family and Medical Leave Act — the FMLA — has been federal law since 1993. And yet, in 2025, most employees still don't fully understand what it covers, whether they qualify, or what their employer is actually required to do.

That gap in knowledge costs people. They don't request leave they're entitled to. They return to work before they're ready. Or they accept denials that shouldn't have happened.

This post is here to change that.

What the FMLA Is

The FMLA is a federal law that allows eligible employees to take up to 12 weeks of unpaid, job-protected leave per year for qualifying reasons — without fear of losing their job.

Job-protected means your employer must hold your position — or an equivalent one — for you while you're on approved leave. They cannot demote you, eliminate your role, or retaliate against you for taking it.

Who Qualifies

Not every employee is automatically covered. To be eligible for FMLA, you must meet all three of the following:

• You work for a covered employer — generally a private employer with 50 or more employees, or any public agency or public school regardless of size

• You have worked for that employer for at least 12 months

• You have worked at least 1,250 hours during the 12 months before your leave begins

If you meet all three, you are eligible. Your employer does not get to decide otherwise.

What FMLA Covers

Qualifying reasons for FMLA leave include:

• The birth, adoption, or foster placement of a child

• Caring for a spouse, child, or parent with a serious health condition

• Your own serious health condition that makes you unable to perform your job

• Qualifying military exigencies related to a family member's active duty service

A serious health condition includes illness, injury, impairment, or physical or mental conditions that involve inpatient care or continuing treatment by a healthcare provider. This includes chronic conditions, pregnancy complications, and mental health conditions that meet the threshold.

What Your Employer Must Do

This is the part most employees don't know — and employers are counting on that.

When you request FMLA leave, or when your employer has reason to believe your absence may qualify, they are required to:

• Notify you of your eligibility within five business days

• Provide you with a notice of your rights and responsibilities

• Designate your leave as FMLA-qualifying once they have enough information to make that determination

Your employer cannot deny your request simply because the timing is inconvenient, your team is short-staffed, or your manager doesn't want to deal with the absence. If you qualify, the law applies.

A Few Things Worth Knowing

FMLA leave does not have to be taken all at once. In many situations, you can take it intermittently — a few hours at a time, or a few days per week — when medically necessary.

FMLA leave is unpaid at the federal level, but your employer may require — or you may choose — to run it concurrently with any accrued paid leave you have available.
