Intermittent FMLA Leave

What is Intermittent FMLA Leave?

Intermittent FMLA leave is leave taken in separate blocks of time for a single qualifying reason, rather than as one continuous absence. It's most often used for chronic or recurring conditions like migraines, asthma flare-ups, or ongoing treatments such as dialysis or physical therapy, where a full block of leave of absence isn't medically necessary.

How Does Intermittent Leave Differ From a Reduced Schedule?

The two are related but distinct. Intermittent leave covers separate, unpredictable absences, like a few hours off for a flare-up. A reduced schedule instead lowers an employee's regular weekly or daily hours for a defined period, such as returning from surgery on a gradually increasing schedule. Indeed confirms employees can take FMLA leave intermittently or reduce their usual schedule to manage a medical condition, and employers cannot require staff to work while on either type of approved leave.

How is Intermittent Leave Calculated?

Unlike a single continuous leave with clear start and end dates, intermittent leave is tracked in small increments that get deducted from an employee's total 12-week entitlement.

How Can Employers Address Suspected Abuse?

Medical certification is the primary tool for keeping intermittent leave honest. SHRM describes a scenario where an employee certified for one four-hour absence per month for migraines instead takes an entire Monday and Friday off; that pattern alone can justify a recertification request without violating the employee's underlying rights.

Employers can also request a new certification at the start of each new FMLA year and seek second or third medical opinions when a certification raises doubts. What employers cannot do is assume abuse from a pattern alone or discipline without an individualized review, since doing so risks interference and retaliation claims. Documenting suspected job abandonment separately from a protected intermittent leave pattern is essential, since conflating the two is a common and costly mistake.

Why Does Intermittent Leave Create Administrative Challenges?

Unpredictable, minute-by-minute tracking is difficult to manage manually, and the stakes of getting it wrong are real. Forbes notes that the average cost of defending a single FMLA lawsuit runs around $80,000, a figure that makes consistent, well-documented administration a financial priority as much as a compliance one.

Purpose-built systems help close this gap. AI leave management software can track hourly increments accurately against a running entitlement balance, while AI absence management software flags patterns worth reviewing without leaving that judgment call entirely to an untrained frontline manager.

Bonding leave adds another wrinkle: intermittent leave for a new child generally requires mutual agreement between employer and employee, unlike medical intermittent leave, which the employee is entitled to whenever medically necessary. Distinguishing this from maternity and parental leave policies helps keep expectations clear before a new parent requests a non-continuous schedule. Keeping absence tracking data organized across every leave type also makes it far easier to spot when an employee is nearing exhaustion of their entitlement, before a difficult conversation becomes an urgent one.

Frequently Asked Questions

Q: What is the smallest increment of intermittent FMLA leave an employer can require?

A: The increment must match whatever unit the employer uses for other forms of leave, but it cannot exceed one hour under federal regulation.

Q: Can an employer deny an intermittent leave request?

A: Not if the employee is eligible and the leave is medically necessary for a qualifying reason. Employers can request certification and recertification but cannot outright deny a legitimate request.

Q: How is intermittent leave different from a reduced schedule?

A: Intermittent leave covers separate, often unpredictable absences, while a reduced schedule lowers an employee's regular hours for a defined period on a consistent basis.

Q: Does intermittent leave for bonding with a new child work the same as medical intermittent leave?

A: No. Intermittent leave for bonding with a newborn or newly placed child generally requires the employer's agreement, unlike medical intermittent leave, which is available whenever medically necessary.

Q: Can an employer request recertification for intermittent leave?

A: Yes, particularly if the employee's absence pattern doesn't match the original certification, at the start of a new FMLA year, or when circumstances described in the certification change significantly.
