FMLA administration is a process with defined stages and deadlines. Employers who run it as a process comply; employers who handle each request as a one-off eventually miss a step. This is the framework.
1. Determine Coverage and Eligibility
Two separate questions. Employer coverage depends on employee count thresholds. Employee eligibility requires 12 months of employment, 1,250 hours worked in the preceding 12 months, and 50 employees
...An employer may require a fitness-for-duty certification before restoring an employee whose FMLA leave was for the employee's own serious health condition, but only under a uniformly applied policy for similarly situated employees, and only if it said so in the designation notice. The certification can address only the condition that caused the leave. It may be required to address the employee's ability to perform the job's essential functions if the employer supplied a list of those ...
During FMLA leave, an employer must keep the employee's group health plan coverage in place on the same terms as if the employee had continued working, and the employee remains responsible for their usual share of the premium. On return, the employee is entitled to the same or an equivalent job and to have benefits restored without having to requalify. Benefits other than group health coverage follow the employer's rules for other types of leave.
The restoration rules themselves are ...
FMLA eligibility turns on three separate tests. An employee must satisfy all three, and each is measured in a specific way that is easy to apply loosely. Getting eligibility wrong in either direction creates exposure — denying leave to an eligible employee is interference, and granting FMLA-designated leave to an ineligible one can create entitlements the employer did not intend.
Test 1: Twelve Months of Employment
The employee must have been employed by the employer for at
...An employee returning from FMLA leave is entitled to the same or an equivalent job, but that right has defined exceptions. Restoration is not required when the job would have ended anyway (a layoff, a completed project or term), when a qualifying key employee's restoration would cause substantial and grievous economic injury, when the employee cannot perform an essential function of the job, when leave was obtained by fraud, or when the employee breaches a uniformly applied ...
The FMLA gives employers real tools, not just obligations. An employer may require medical certification and, within limits, recertification; ask employees to schedule planned treatment to reduce disruption; temporarily transfer an employee on foreseeable intermittent leave; require paid leave to run concurrently; require status reports and a fitness-for-duty certification; and recover health premiums from an employee who does not return. Each right comes with conditions, and most FMLA ...
FMLA claims rarely arise because an employer refused leave outright. They arise from administrative failures — notices sent late, certifications mishandled, intermittent leave miscounted — each of which looks minor in isolation and compounds into an interference or retaliation claim.
These are the failures that recur.
1. Not Recognizing an FMLA Request
Employees are not required to say "FMLA". They are required to provide enough information for the employer to know
...FMLA rarely operates alone. A single absence can engage federal FMLA, a state family and medical leave law, a paid family leave program, short-term disability, workers' compensation, the ADA and a company policy — each with its own eligibility rules, durations and obligations.
Getting the coordination wrong produces one of two errors: granting more leave than required, or denying leave that was owed. The second is considerably more expensive.
Decide Concurrency in
...FMLA failures are almost never decisions. They are handovers — a conversation that was not escalated, a notice generated but not evidenced, a certification requested but not diarised, an exhaustion date that triggered a system rule.
Building a process around those handover points is more effective than trying to be careful in general.
Intake: Where It Starts Going Wrong
The obligation begins when an employee provides enough information for the employer to know leave
...Intermittent leave creates more administrative difficulty than any other part of FMLA, and the difficulty is genuine rather than a failure of organization. Absences are unpredictable, increments are small, and the tracking burden sits with the employer.
The Increment Rule
Intermittent leave must be counted in increments no greater than the shortest period the employer uses to account for other forms of leave. An employer tracking other leave in fifteen-minute increments
...FMLA denials are legitimate in defined circumstances and indefensible outside them. The risk is not in denying leave that does not qualify — it is in denying for a reason that sounds sensible but is not one the statute recognizes.
The Legitimate Grounds
The employee is not eligible
Eligibility requires twelve months of employment, 1,250 hours worked in the preceding twelve months, and fifty employees within seventy-five miles of the worksite. Failing any of the
...The FMLA guarantees job protection. It does not guarantee a paycheck. That gap is what state paid family and medical leave programs exist to close — and over the last decade enough states have built them that "we follow FMLA" is no longer a workable leave strategy for any employer operating in more than one state.
For HR and payroll teams, these programs create three distinct obligations that are easy to conflate: a payroll tax obligation, a notice and posting obligation, and a job ...
The Threshold Question: Are You a Covered Employer?
Every FMLA question downstream — how much leave, what certification, what job restoration is owed — depends on one threshold determination: is this employee eligible? Get it wrong in one direction and you deny protected leave. Get it wrong in the other and you can create an entitlement that did not legally exist but that you are now estopped from taking back.
Here is how the determination actually works, in the order
...Continuous FMLA leave is straightforward: the employee is out, you backfill the role, they return. Intermittent leave is where FMLA administration actually gets hard. The employee is at work — until suddenly they aren't, for two hours on a Tuesday, or every third Thursday, or for a week whenever a chronic condition flares. Your timekeeping system wasn't built for it, your managers resent it, and the regulations governing it are unforgiving of shortcuts.
