FMLA Intermittent Leave Notice Requirements for Employers
A practical employer guide to intermittent FMLA notice requirements, including employee call-ins, certification, frequency and duration, absence tracking, recertification, and common employer mistakes.
Intermittent FMLA Quick Facts
Use this section as a quick employer reference for intermittent leave communication and tracking.
What Is Intermittent FMLA Leave?
Intermittent FMLA leave is leave taken in separate blocks of time for a single FMLA-qualifying reason.
Separate Blocks of Time
Intermittent leave may involve occasional absences, medical appointments, flare-ups, treatment, recovery periods, or other qualifying absences.
- Separate absences for one qualifying reason
- May include appointments or flare-ups
- May vary by frequency and duration
- Requires accurate time tracking
Different From Reduced Schedule Leave
Reduced schedule leave changes the employee’s normal work schedule for a period of time, such as moving from full-time to part-time temporarily.
- Temporary schedule reduction
- Usually planned in advance
- May require medical necessity
- Should be tracked separately from random intermittent absences
What Should Employers Communicate?
Intermittent FMLA communication should explain the employee’s responsibilities and the employer’s tracking expectations.
Call-In and Reporting Rules
Employees should understand how to report each intermittent absence and whether normal attendance procedures still apply.
- Who to notify
- How to report the absence
- When notice is due
- How to identify the absence as related to approved FMLA
Frequency and Duration
Certification should support the expected frequency and duration of intermittent leave when applicable.
- Expected episodes per week or month
- Expected duration per episode
- Treatment schedule
- Need for follow-up if usage exceeds certification
Leave Usage Tracking
Employers should track intermittent FMLA usage in the smallest increment allowed by policy and FMLA rules.
- Date of absence
- Hours used
- Reason code
- Remaining entitlement
Intermittent FMLA Workflow
Employers should build a repeatable workflow for every intermittent absence.
Receive Leave Request
Employee reports a need for intermittent leave, treatment, appointments, flare-ups, or recurring absences.
Send Required Notices
Provide eligibility, rights and responsibilities, and certification request when appropriate.
Review Certification
Confirm whether certification supports intermittent leave frequency, duration, and medical necessity.
Designate Leave
Send the Designation Notice once enough information is available to determine whether leave qualifies.
Track Each Absence
Track date, hours used, call-in compliance, payroll coding, and remaining FMLA entitlement.
Review Patterns
Review usage against certification and consider recertification when allowed by FMLA rules.
FLARE™ Insight
Intermittent FMLA becomes difficult when employers approve the leave but fail to build the tracking system. The approval is only the beginning. Employers need absence codes, manager instructions, payroll alignment, recertification triggers, and a clear process for reviewing usage that exceeds the certified frequency or duration.
Common Intermittent FMLA Mistakes
These are the mistakes employers should audit when managing intermittent leave.
No Frequency or Duration Review
Employers should compare actual usage to the certified frequency and duration.
Managers Coding Time Incorrectly
Managers should know how to report intermittent FMLA without receiving unnecessary medical details.
No Payroll Coordination
Intermittent leave can affect pay, accruals, attendance points, deductions, and timekeeping.
Not Enforcing Call-In Rules
Employees should generally follow normal call-in procedures unless unusual circumstances apply.
Ignoring Pattern Concerns
Usage patterns may support review or recertification when allowed, but employers need documentation.
No Entitlement Balance
Employers should track remaining FMLA entitlement accurately, especially when leave is used in hours.

| Item | Employer Action | Why It Matters | Documentation to Keep |
|---|---|---|---|
| Leave Reason | Confirm whether the intermittent absence relates to the approved FMLA reason. | Prevents miscoding unrelated absences as FMLA. | Call-in notes, absence reason, approved leave file. |
| Certification Limits | Review certified frequency, duration, treatment schedule, and estimated need. | Supports usage review and recertification decisions. | Certification copy, review notes, designation record. |
| Call-In Compliance | Confirm the employee followed normal reporting procedures when applicable. | Supports consistent attendance administration. | Call logs, attendance system, manager notes. |
| Time Used | Track date, hours, and increments of FMLA used. | Maintains accurate entitlement balance. | Time records, payroll codes, leave tracker. |
| Pattern Review | Compare usage to certification and review significant changes. | Helps identify when recertification may be appropriate. | Absence pattern report, HR review notes. |
| Remaining Entitlement | Update the employee’s remaining FMLA balance after each absence. | Prevents exhaustion and payroll errors. | Entitlement balance, employee communication, leave calendar. |
