Common Pitfalls in FMLA Administration

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 the leave may be FMLA-qualifying. An employee who says they will be out because their mother is having surgery has triggered the employer's obligation to inquire further.

The failure mode is a supervisor treating that conversation as a routine absence request and never passing it to HR. Training supervisors to escalate is the single highest-value control available.

2. Late or Missing Designation

The FMLA imposes notice obligations with defined timeframes — eligibility notice, rights and responsibilities notice, and designation notice. Employers who provide leave but never designate it as FMLA create two problems: the entitlement is not counted against the employee's allowance, and the failure itself can support an interference claim.

Designating leave is not optional or discretionary. Where leave qualifies, it must be designated.

3. Mishandling Medical Certification

Certification has its own rules and they are frequently ignored:

• Employees must be given a reasonable period to return certification.
• Where a certification is incomplete or insufficient, the employer must identify what is missing in writing and allow an opportunity to cure — not simply deny the leave.
• The direct supervisor must not contact the health care provider.
• Second and third opinions are available in defined circumstances and at the employer's expense.

Denying leave on an incomplete certification without giving a cure opportunity is among the most common procedural failures.

4. Miscounting Intermittent Leave

Intermittent leave must be counted in increments no greater than the shortest increment used for other forms of leave. Employers who deduct a full day for a two-hour absence are over-counting the entitlement, which reduces the employee's remaining leave and creates exposure.

The record-keeping burden here is real, and it is the employer's burden, not the employee's.

5. Applying the Wrong 12-Month Method

The FMLA permits several methods of measuring the 12-month period — calendar year, fixed year, measured forward, or rolling backward. The employer must choose one, apply it consistently, and communicate it. Employers who never chose, or who apply different methods to different employees, cannot defend their leave calculations.

6. Treating FMLA Exhaustion as the End of the Analysis

When FMLA entitlement runs out, the ADA analysis often begins. Additional leave can be a reasonable accommodation. Terminating at FMLA exhaustion without considering accommodation is a well-established route to liability — and it frequently happens automatically through a system rule rather than a decision.

See light-duty assignments under FMLA, ADA and workers' compensation for how the laws interact.

7. Inconsistency

Granting leave readily to one employee and scrutinizing another creates a discrimination claim independent of the FMLA itself. Consistency is defensible; discretion applied unevenly is not.

8. Poor Documentation

The employer bears the burden of showing it met its obligations. Notices generated but not evidenced, conversations not recorded, and certifications filed without tracking dates all leave the file unable to demonstrate compliance.

Controls That Prevent Most of This

1. Train supervisors to escalate any absence that might qualify, without assessing it themselves.
2. Use a checklist tied to the statutory notice deadlines.
3. Track certification request, receipt, cure and expiry dates.
4. Count intermittent leave in the smallest increment you use for other leave.
5. Document the 12-month method and apply it uniformly.
6. Build an ADA review into the FMLA exhaustion process rather than an automatic termination.

The Supervisor Problem

Most FMLA failures begin with a conversation HR never hears about. An employee mentions a medical issue to their manager, the manager treats it as a routine absence request, and the employer's notice obligations start running without anyone knowing.

No amount of HR diligence compensates for this. The control is supervisor training with one clear instruction: you are not required to assess whether leave qualifies, and you are required to report anything that might. Removing the judgment from supervisors removes the failure mode.

System-Driven Terminations

A related failure is automated. Absence management systems configured to trigger termination at FMLA exhaustion will do exactly that, without anyone considering whether additional leave is a reasonable accommodation under the ADA.

Configure the system to flag rather than to act. The exhaustion date should generate a review, not an outcome.

Frequently Asked Questions

Can an employee decline FMLA designation?

No. Where leave qualifies, the employer must designate it.

Can we require a fitness-for-duty certification?

Where the policy is uniformly applied and the requirement was stated in the designation notice.

What if the employee will not return certification?

Leave may be denied, provided the employee was given a reasonable period and written notice of what was required.
