FMLA Intermittent Leave: The Employer’s Survival Guide

Ask any HR manager what their biggest FMLA headache is and intermittent leave tops the list almost every time. It is unpredictable. It disrupts operations. It is difficult to track. And the rules around it are strict enough that mistakes create real liability.

The good news is that intermittent leave is manageable. Understanding the rules clearly is the first step. Building a system around those rules is the second. Here is everything employers need to know.

What intermittent leave actually is

Intermittent FMLA leave means an employee takes leave in separate blocks of time rather than all at once. The blocks can be hours, days, or weeks. They can be scheduled in advance or completely unpredictable.

A cancer patient who takes every Friday off for chemotherapy is on intermittent leave. An employee with migraines who calls in sick two or three times a month is on intermittent leave. An employee with a chronically ill child who occasionally needs to leave early for medical appointments is on intermittent leave.

All three situations qualify for FMLA protection as long as the underlying condition meets the definition of a serious health condition. The fact that the leave is sporadic does not make it any less protected.

When intermittent leave is allowed

Employees can take intermittent leave in three situations. First, when medically necessary for their own serious health condition. Second, when medically necessary to care for a family member with a serious health condition. Third, for the birth or placement of a child — but only if the employer agrees to intermittent leave for bonding purposes.

That third situation is important. For baby bonding leave, the employer has the right to require that leave be taken in a continuous block rather than intermittently unless the employer agrees otherwise. This gives employers some scheduling flexibility for bonding leave that does not exist for medical leave.

The minimum increment rule

Employers can set a minimum increment for intermittent leave tracking. However, that increment cannot exceed the shortest period of time the employer’s payroll system uses to account for absences.

If your payroll system tracks time in one-hour increments, you can require intermittent leave to be taken in one-hour minimum blocks. If your system tracks in 15-minute increments, your minimum increment for FMLA leave must also be 15 minutes.

This matters because employees on intermittent leave for conditions like migraines or chronic pain may need to leave for shorter periods. Requiring them to take a full day when they only need two hours can constitute FMLA interference.

Notice requirements for intermittent leave

Notice requirements for intermittent leave depend on whether the need is foreseeable or unforeseeable.

When the need is foreseeable — scheduled treatments or predictable flare-ups — employees must provide advance notice as soon as practicable. They should also make reasonable efforts to schedule treatments at times that minimize disruption to operations.

When the need is unforeseeable — a sudden migraine or an unexpected flare-up — employees must notify you as soon as practicable. For unforeseeable intermittent leave, following your normal call-in procedures is generally required unless unusual circumstances prevent it.

An employee who fails to follow your call-in procedures for unforeseeable intermittent leave can be disciplined for the procedural violation. However, you cannot deny FMLA protection for the underlying absence simply because the employee did not call in correctly.

Tracking intermittent leave accurately

Accurate tracking is where intermittent leave administration breaks down for most HR teams. Every instance of intermittent leave must be recorded — the date, the duration, and the reason. Running totals must be maintained against the employee’s 12-week annual entitlement.

The tracking must use the correct 12-month period method your organization has adopted. Rolling backward is the most common method because it prevents employees from taking back-to-back 12-week blocks. However, it also requires recalculating each employee’s available leave every time they request an absence.

Manual tracking of intermittent leave across multiple employees creates serious error risk. A missed entry means your records are wrong. Wrong records mean your entitlement calculations are wrong. Wrong calculations mean you may deny leave an employee is entitled to or fail to count leave that should have been counted.

Addressing suspected intermittent leave abuse

Intermittent leave abuse is a genuine concern for employers. Patterns of absences on Mondays and Fridays, absences that coincide with sporting events or holidays, and sudden increases in intermittent leave before scheduled discipline are all patterns that raise legitimate questions.

However, addressing suspected abuse requires careful handling. You cannot deny FMLA protection simply because you suspect abuse. You have specific tools available to you.

Recertification is the most powerful tool. You can request recertification of the underlying condition every 30 days in connection with an absence. If the medical certification does not support the frequency or duration of absences, you can request clarification from the healthcare provider.

Second opinion examinations are also available. When you have reason to doubt the validity of a medical certification, you can require the employee to obtain a second opinion from a healthcare provider of your choosing at your expense.

Fitness for duty certifications can require the employee to provide medical clearance before returning from each intermittent absence when the condition involves a chronic condition that may affect their ability to perform their job.

Building a sustainable intermittent leave process

The employers who manage intermittent leave most effectively share one thing in common. They have a systematic process that applies consistently to every employee on intermittent leave.

That process includes clear call-in procedures that employees acknowledge in writing. It includes a tracking system that records every absence and maintains running totals automatically. It includes regular reviews of certifications and timely recertification requests when appropriate. And it includes documentation of every conversation and every decision related to intermittent leave.

FMLAPro Tracker Pro was built specifically around the complexity of intermittent leave tracking. It records every instance, maintains running totals automatically, and alerts you when an employee is approaching their entitlement limit. It runs inside Microsoft Excel so your team can start using it immediately. Visit our store to learn more or contact us with any questions.
