The threshold that sneaks up on a growing company
The Family and Medical Leave Act (FMLA) is the federal law that gives eligible employees up to 12 weeks of unpaid, job-protected leave in a 12-month period for specific family and medical reasons. The reason it surprises small employers is that it switches on quietly: a private company becomes a "covered employer" once it has 50 or more employees for at least 20 workweeks in the current or preceding calendar year. A startup that hires steadily can cross that line mid-year without anyone noticing — and the obligations attach whether or not anyone in HR realized the company tipped over the threshold.
This is general HR education, not legal advice. The FMLA is a detailed federal statute with its own regulations, and several states layer their own (often more generous) family-and-medical-leave laws on top. Confirm the specifics for your headcount and every state where you have workers before you act on any individual leave request.
Two thresholds, not one: covered employer vs. eligible employee
The single most common FMLA mistake is conflating being covered with every employee being entitled. They are separate tests, and an employee only has FMLA rights when both are satisfied.
First, is the employer covered? Fifty or more employees for 20+ workweeks in the current or prior year. Below that, the federal FMLA generally does not apply at all — though a state law might.
Second, is the specific employee eligible? Even at a covered employer, an individual must meet all three of these:
- Worked for you for at least 12 months (they need not be consecutive).
- Worked at least 1,250 hours in the 12 months before the leave starts — roughly 24 hours a week averaged over the year.
- Works at a site with 50+ employees within 75 miles. This worksite rule is what trips up distributed teams: a remote employee's "worksite" is generally the office they report to or take assignments from, not their home — but you have to apply the test deliberately rather than assume.
A brand-new hire, a part-timer well under 1,250 hours, or someone at an isolated small site may not be eligible even though the company is covered. Run both tests before you grant or deny anything.
What the leave actually covers
FMLA leave is available for a defined set of reasons, not general personal time:
- The employee's own serious health condition that makes them unable to perform their job.
- Caring for a spouse, child, or parent with a serious health condition.
- The birth of a child and bonding, or placement of a child for adoption or foster care.
- Qualifying exigencies arising from a family member's military deployment, plus an extended military caregiver leave (up to 26 weeks) for the serious injury or illness of a covered servicemember.
"Serious health condition" is a term of art — it generally means inpatient care or continuing treatment by a health provider, not a one-day cold. You are allowed to require medical certification to support a leave request, and to require periodic recertification, but within the limits the regulations set.
Intermittent leave: the part that's hard to administer
FMLA leave does not have to be taken in one continuous block. When medically necessary, an eligible employee can take it intermittently — a few hours for recurring treatment, or reduced-schedule weeks — which is administratively the hardest version to track. You are entitled to require that the employee follow your normal call-in procedures and, where foreseeable (a scheduled surgery, a planned course of treatment), to give reasonable advance notice. But you cannot count protected FMLA absences against an employee under a no-fault attendance policy — the same anti-retaliation principle that governs paid sick leave. If your points system dings a legally protected absence, that is itself a violation.
Accurate hours tracking is what makes intermittent leave survivable. You need to know precisely how much of the 12-week entitlement each increment consumes, which is the same daily-hours discipline that timekeeping for exempt and non-exempt classification already demands.
The promise at the center of the law: job restoration
The reason FMLA leave is called job-protected is the restoration right. When an employee returns from FMLA leave on or before the end of their entitlement, you must generally restore them to the same job, or an equivalent one — equivalent pay, benefits, and terms — not a lesser role. You also must maintain their group health coverage during the leave on the same terms as if they were working.
There is a narrow exception for certain highly compensated "key employees," and restoration is not absolute — if the position would have been eliminated regardless of the leave (a genuine reduction in force the employee would have been part of anyway), the law does not freeze it in place. But the default is strong, and the burden is on the employer to show an exception applies. Treat the returning employee's old job as reserved unless you have a documented, leave-independent reason it no longer exists. If a separation does become necessary, run it through the same disciplined offboarding process you'd use for anyone, with the timing and rationale documented.
Notice and paperwork run both ways
The FMLA imposes notice duties on the employer, not just the employee:
- A general notice of FMLA rights, typically a workplace poster and a statement in your employee handbook.
- An eligibility and rights-and-responsibilities notice to the employee within a few business days of learning a leave may be FMLA-qualifying.
- A designation notice telling the employee whether the leave is being counted as FMLA and how much of their entitlement it uses.
Recordkeeping matters: the FMLA requires you to keep leave records for several years, which overlaps with the broader recordkeeping discipline you already maintain. The recurring failure pattern is not denying valid leave outright — it's missing the designation paperwork, mistracking the 12-week balance, or quietly disadvantaging someone on return. All three are avoidable with a written process.
A small-employer checklist
- Watch the 50-employee line as you grow, and know the date you crossed it — coverage is not optional once you're over.
- Run both tests — employer covered and employee eligible (12 months, 1,250 hours, 50-in-75-miles) — before granting or denying.
- Get the notices and designation out on time, and require certification within the rules.
- Track intermittent leave precisely and never count protected absences against attendance.
- Reserve the job. Restore to the same or an equivalent role and maintain health coverage throughout.
- Check state law, which may cover smaller employers, add paid benefits, or extend reasons beyond the federal floor.
The FMLA is not a small-employer problem until, suddenly, it is — the moment you cross 50 employees. Build the eligibility tests, the notice timeline, and the job-restoration promise into a written process before you get there, and a leave request becomes a workflow you execute rather than a panic. When a specific situation is genuinely ambiguous — a contested "serious health condition," a key-employee question, a multi-state overlap — that is the moment to confirm with counsel rather than guess. The entitlements are federal, the penalties attach per violation, and the restoration right is the part courts take most seriously.
