The FMLA Eligibility Test Managers Get Wrong

A manager hears that an employee needs time off for a parent's surgery and assumes the Family and Medical Leave Act automatically applies. It might not. The FMLA is not a blanket entitlement that follows every worker at every company — it is a three-part test, and missing any one part means the leave in question is not FMLA leave, whatever the employer decides to call it.

The first part is about the employer, not the employee. The law only reaches companies of a certain size: it applies to any employer in the private sector who has 50 or more employees each working day during at least 20 calendar weeks in the current or preceding calendar year. A small business under that line has no FMLA obligation at all, however sympathetic the situation looks. That threshold catches out a surprising number of growing companies, which assume a federal leave law must apply to them simply because they run payroll, and then discover either that they are not covered, or that they crossed the line a while back and have been out of compliance since.

Coverage is not the same as eligibility

Even inside a covered company, not every employee qualifies. The individual has to clear service and hours thresholds of their own, and the hours test is strict: the employee must work 1,250 hours in the previously 12 months. A worker hired recently, or one who has been on reduced hours, can fail this test even at a company that is fully covered. It is estimated that only about 50 percent of U.S. employees are covered by the FMLA. That share surprises most managers, who tend to assume the law is close to universal once the employer-size test and the individual eligibility test are both applied.

Employment lawyers describe the same handful of mistakes coming up again and again. One is timing: eligibility should be checked the first time an employee takes leave for a particular qualifying reason within the employer's FMLA year, not re-checked on every later request for that same reason. Once eligibility is established, it holds for the rest of the year, and treating each request as a fresh question creates inconsistency that looks, from the outside, a lot like favoritism or its opposite.

Service time hides in unexpected places

The tenure test trips people up in a different way. Months worked in previous periods of employment must be counted, unless there has been a break in service of more than seven years. That means a boomerang hire who left the company and later returned may already have cleared the service-time bar on the first day back, well before a manager would expect it. HR systems built around a single continuous hire date can miss this entirely, quietly denying leave to someone who is, on paper, already eligible.

Remote work adds its own wrinkle. An employee's home is not treated as their FMLA worksite; eligibility instead runs against the office they report to and receive assignments from, and a separate headcount rule applies to that location rather than to the employee's kitchen table. A company with remote staff scattered nationally, all nominally assigned to one small office, may find that none of them clear this part of the test even though the company overall is large.

What the eligibility call is actually worth

None of this means an employer should refuse leave the moment eligibility looks doubtful. An eligible employee with a qualifying reason is entitled to 12 weeks of leave in a 12-month period. Getting the eligibility call wrong in either direction carries a real cost: wrongly granting FMLA-protected leave sets a precedent that is hard to walk back later, while wrongly denying it exposes the company to a claim that it interfered with a right the employee actually had.

The safer habit is to run the same three checks every time — employer size, individual tenure and hours, and worksite — and to write down the answer along with the reasoning behind it. A short checklist beats an assumption, and a paper trail is worth far more than a guess once the decision is questioned months later, after the employee has already returned to work or, worse, already left. None of this requires a lawyer for every case, just a habit of checking rather than guessing, and a manager willing to say plainly that the answer needs confirming instead of answering on the spot.
