Overview
Intermittent leave — when an employee takes short, irregular periods of time off for a qualifying health reason — creates practical and compliance challenges for employers and HR teams.
This guide explains how intermittent leave typically operates, common employer options, and practical steps to manage attendance while protecting employees' rights.
Key takeaways
- Employees on intermittent leave must follow reasonable call-in and notice rules set by the employer.
- Employers can request medical recertification, require documentation, and explore reasonable accommodations to reduce disruption.
- Consistent, documented application of your policies helps avoid claims of unfair treatment.
How it works
An eligible employee may take intermittent leave for a serious health condition or to care for a covered family member, using short absences rather than a single continuous period.
Employers may require medical certification to support intermittent leave; for an overview of federal leave rules and when certification is appropriate, see Family and Medical Leave Act (FMLA) Overview.
When leave is unpredictable, employers can set reasonable call-in procedures and attendance reporting requirements so both sides understand expectations.
What it may cover (and what it may not)
Intermittent leave can cover recurring treatment, chronic conditions, or episodic flare-ups that meet the law’s definition of a serious health condition.
It usually does not cover minor, short-term illnesses or non-medical reasons unless those reasons are separately protected by company policy or another law.
For situations where medical leave intersects with short-term benefits, review guidance such as Short-Term Disability Insurance to see how wage replacement and leave may interact.
Common mistakes to avoid
Failing to apply call-in or no‑show policies consistently can expose an employer to claims of discrimination or interference; document every administration of the rule.
Another common error is not verifying medical documentation when reasonable doubts arise — employers may request recertification under appropriate circumstances to confirm continued eligibility.
Also avoid assuming intermittent leave can be ignored because it is short; frequent absences may justify a discussion about a temporary alternative position or reasonable accommodation, as explained in Family and Medical Leave Act and Health Insurance Insights.
Questions to ask an agent
- How do our absence policies align with federal and state leave requirements?
- What documentation should we request and how often can we request recertification?
- When is it appropriate to offer an accommodated position that reduces the need for intermittent leave?
If you need personalized help interpreting benefits or policy language, ask an agent.
Next steps
Review and update your written call-in and attendance policies to ensure they are reasonable, clearly communicated, and applied evenly across similar cases.
Train supervisors on how to document leave-related conversations and when to escalate requests for recertification or accommodation.
Keep records of certifications, recertifications, and any accommodations offered so you can demonstrate consistent treatment if questions arise.
Frequently Asked Questions
Can an employer require employees to follow call-in procedures during intermittent leave?
Yes. Employers may enforce reasonable call-in and notice procedures as long as they are applied consistently and do not directly conflict with required medical treatment schedules.
When can an employer request recertification for intermittent leave?
Recertification can be requested when circumstances change significantly or when the employer has reason to doubt the validity of the original certification, subject to legal limits on timing and frequency.
Does intermittent leave always come with pay?
No. Intermittent leave provides job-protected time off but does not automatically guarantee paid leave unless a separate benefit, such as short-term disability or employer policy, provides pay.
Can an employer require an employee to accept an accommodated position to reduce leave usage?
An employer may offer a reasonable accommodation or temporary reassignment, but acceptance is subject to interactive discussion and applicable accommodation laws.
