Intermittent FMLA in Ohio works entirely under federal law, because Ohio has no state-level family or medical leave statute. The federal Family and Medical Leave Act gives eligible employees up to 12 weeks of unpaid, job-protected leave per year, and that leave can be taken in separate blocks of time rather than all at once when a medical need supports it.1U.S. Department of Labor. Fact Sheet 28 – The Family and Medical Leave Act For Ohio workers managing chronic conditions, recurring treatments, or caregiving duties, that intermittent option is often the only realistic way to hold a job while handling health needs.
Who Is Eligible
Three conditions all have to be met before you can request any FMLA leave in Ohio, intermittent or otherwise. Your employer must have at least 50 employees within 75 miles of your worksite. You must have worked for that employer for at least 12 months, though the months do not have to be consecutive. And you must have logged at least 1,250 hours of actual work during the 12 months before your leave starts.2eCFR. 29 CFR 825.110 – Eligible Employee
Those 1,250 hours count only time you were actually working. Paid holidays, vacation, and sick leave where you were off the clock do not add to the total. Payroll records are the definitive source if you need to check, and your employer is required to maintain them.
When You Can Use Leave Intermittently
Intermittent leave is available when a medical need makes it necessary and periodic absences fit that need better than one long stretch away from work.3eCFR. 29 CFR 825.202 – Intermittent Leave or Reduced Leave Schedule The common qualifying reasons:
- Your own serious health condition, including chronic conditions like migraines, diabetes, epilepsy, or depression that cause unpredictable flare-ups, and conditions requiring scheduled treatments like chemotherapy, dialysis, or physical therapy.
- Caring for a spouse, child, or parent with a serious health condition who needs help with appointments, treatment, or episodes of incapacity.
- Military caregiver leave for the spouse, child, parent, or next of kin of a current servicemember with a serious injury or illness, which allows up to 26 weeks in a single 12-month period (that 26-week cap includes any other FMLA leave used during the same period).4U.S. Department of Labor. Military Caregiver Leave for a Current Servicemember under the Family and Medical Leave Act
- Qualifying exigencies tied to a family member’s active-duty military deployment, such as attending military briefings, arranging childcare, or handling related financial and legal matters.
Bonding leave with a newborn or newly placed child is the one notable exception. You can only take bonding leave intermittently if your employer agrees. If a medical complication for the mother or child makes periodic absences necessary, the leave shifts into the serious-health-condition category and employer agreement is no longer required.5U.S. Department of Labor. Fact Sheet 28Q – Taking Leave from Work for the Birth, Placement, and Bonding with a Child under the FMLA
What Counts as a Serious Health Condition
Not every illness qualifies. A serious health condition under FMLA generally involves either inpatient care, or a period of incapacity lasting more than three consecutive full calendar days combined with ongoing treatment. To meet the incapacity-plus-treatment test, the person must see a health care provider within seven days of the first day of incapacity, and then either follow a prescribed course of treatment such as prescription medication or have at least one additional provider visit within 30 days.6U.S. Department of Labor. Taking Leave from Work When You or Your Family Member Has a Serious Health Condition under the FMLA
Chronic conditions have their own path. A condition like asthma, Crohn’s disease, or epilepsy qualifies when it requires periodic visits for treatment, continues over an extended period, and may cause episodic rather than continuous incapacity. Most intermittent-leave users rely on this provision, because chronic conditions by nature involve unpredictable flare-ups followed by stretches of normal function.
How to Request It
Requests center on a medical certification form your health care provider completes. For your own condition, use Department of Labor Form WH-380-E. For a family member’s condition, use Form WH-380-F. Both are available from HR or directly from the Department of Labor website.7U.S. Department of Labor. FMLA Forms
The certification asks your provider to describe the condition, when it started, its probable duration, and the medical facts supporting why you need time away from work. For intermittent leave, the critical section is the one asking for expected frequency and duration of episodes. A vague “as needed” invites problems. What works is concrete: “approximately two episodes per month, each lasting four to six hours,” or “weekly physical therapy appointments of one hour.” The more specific your provider is, the smoother the approval.
Your employer should request the certification when you first give notice of the need for leave, or within five business days. Once asked, you have at least 15 calendar days to return the completed form.8eCFR. 29 CFR 825.305 – Certification If the form comes back incomplete or unclear, the employer must tell you in writing exactly what is missing and give you seven calendar days to fix it. An employer cannot deny leave simply because a first submission was imperfect.
What Happens After You Submit
Within five business days of receiving your certification, the employer must issue a Designation Notice telling you whether your leave is approved and how it will count against your 12-week entitlement.9eCFR. 29 CFR 825.300 – Employer Notice Requirements
If the employer doubts your certification, it can require a second opinion from a provider of its choosing (not one it regularly uses), at the employer’s expense. A conflicting second opinion can trigger a third, binding opinion from a provider both sides agree on, again at the employer’s expense.10eCFR. 29 CFR 825.307 – Authentication and Clarification of Medical Certification While this plays out, you are provisionally entitled to leave and continued health benefits.
Once approved, recertification can be requested no more often than every 30 days, and only when it coincides with an actual absence. If your certification states a minimum duration longer than 30 days, the employer must wait until that minimum expires.11eCFR. 29 CFR 825.308 – Recertification This is a common friction point. Some employers push for recertification more aggressively than the rules allow, so knowing the 30-day floor matters.
Calling In Each Absence
Approval is only the first step. Every time you use the leave, you have to notify your employer, and the rules differ depending on whether the absence is planned or unexpected.
For foreseeable absences like a scheduled treatment, give at least 30 days’ advance notice when possible. If 30 days is not practical, give notice as soon as you can. For unforeseeable flare-ups or emergencies, you must notify your employer as soon as practicable, which usually means following the company’s normal call-in procedure.12eCFR. 29 CFR 825.303 – Employee Notice Requirements for Unforeseeable FMLA Leave
One detail trips people up. The first time you take leave for a particular qualifying reason, you do not need to mention FMLA by name; you just need to give enough information for the employer to recognize that the absence might qualify. But if you have previously taken FMLA leave for the same condition, later call-ins must specifically reference the qualifying reason or state that you need FMLA leave. Simply calling in “sick” is not enough to trigger your employer’s obligations. Getting this wrong can mean absences get counted against you under a regular attendance policy, so build the habit of referencing your condition or FMLA status every time you call in.
How Your Hours Get Counted
Your 12-week entitlement converts into hours based on your normal workweek. A 40-hour-per-week employee has 480 protected hours. At 30 hours per week, your entitlement is 360 hours. Every intermittent absence chips away at that total.
Employers must track intermittent leave in increments no larger than the shortest increment they use for any other type of leave, and that increment can never exceed one hour.13eCFR. 29 CFR 825.205 – Increments of FMLA Leave for Intermittent or Reduced Schedule Leave If vacation is tracked in 15-minute blocks, FMLA leave must be tracked the same way. An employer that deducts a half-day for a 45-minute doctor visit is violating the rules.
Mandatory overtime adds a wrinkle. If your condition prevents you from working required overtime, those missed overtime hours can be counted against your FMLA balance. Voluntary overtime you skip cannot be counted.14U.S. Department of Labor. Fact Sheet 28I – Counting Leave Use under the Family and Medical Leave Act The distinction matters most in manufacturing and healthcare settings where mandatory overtime is routine.
Employers use one of four methods to measure the 12-month period in which your entitlement runs: a calendar year, a fixed 12-month period such as a fiscal year, a rolling 12 months measured backward from any leave date, or a rolling 12 months measured forward from your first day of leave. Which method applies can significantly affect how much leave you have at any given time, so ask HR which one your employer uses.
Temporary Transfer to Another Position
This catches many employees off guard. If your intermittent leave is foreseeable and based on planned medical treatment, your employer can temporarily transfer you to a different position that better accommodates your absences. The alternative position must provide equivalent pay and benefits, but it does not have to involve the same duties.15eCFR. 29 CFR 825.204 – Transfer of Employee to an Alternative Position
An employer could, for example, move a front-line worker whose scheduled treatments require leaving at noon every Tuesday to a back-office role where midday absences cause less disruption. The employer can also shift you to part-time work at the same hourly rate, as long as you are not forced to take more leave than medically necessary. The transfer lasts only for the duration of the intermittent leave arrangement, and you return to your original position or an equivalent one once the need ends.
This option does not apply to unforeseeable intermittent leave. If your absences are triggered by unpredictable flare-ups rather than a planned treatment schedule, the employer cannot use the transfer provision.
Pay and Health Insurance While on Leave
FMLA leave is unpaid by default, but you will not necessarily go without a paycheck. You can choose to use your accrued paid time off, vacation, or sick leave at the same time as FMLA leave. Your employer can also require you to use accrued paid leave before or alongside unpaid FMLA time.16eCFR. 29 CFR 825.207 – Substitution of Paid Leave The leave still counts as FMLA-protected. Using PTO does not add extra weeks to your entitlement; it just means you get paid during weeks that would otherwise be unpaid.
Your employer must keep your group health insurance in place during FMLA leave on the same terms as if you were still working. If the employer normally covers 80% of the premium, that continues. You remain responsible for your usual employee share.17eCFR. 29 CFR 825.209 – Maintenance of Employee Benefits For intermittent leave this is rarely disruptive since you are still working most of the time, but if your absences stretch enough that payroll deductions get complicated, work out a payment arrangement with HR early so coverage does not lapse.
Returning to Your Job
When your intermittent leave ends, or between periods of leave, you are entitled to return to the same position you held before, or to an equivalent position with the same pay, benefits, and working conditions. This applies even if your employer filled your role or restructured your duties while you were out.18eCFR. 29 CFR 825.214 – Employee Right to Reinstatement
There is one narrow exception. If you are a salaried employee among the highest-paid 10% within 75 miles of your worksite, your employer may classify you as a “key employee.” Key employees can be denied reinstatement, but only if the employer shows that restoring you would cause “substantial and grievous economic injury” to operations. That is a high bar. Minor inconvenience or ordinary replacement costs do not meet it.19U.S. Department of Labor. Family and Medical Leave Act Advisor – Key Employees and Their Rights Even then, the employer has to notify you in writing when you request leave that you qualify as a key employee and explain the potential consequences, and must send a second written notice if it later decides to deny reinstatement, giving you a reasonable opportunity to return. An employer that skips these notice steps loses the right to deny reinstatement entirely.
Protection From Retaliation
Federal law prohibits employers from interfering with your FMLA rights or retaliating against you for using them. Interference includes obvious moves like denying a valid request, and subtler ones: discouraging you from taking leave, manipulating your schedule to keep you below the eligibility threshold, counting FMLA absences under a no-fault attendance policy, or using your leave as a negative factor in hiring, promotions, or discipline.20eCFR. 29 CFR 825.220 – Protection for Employees Your employer also cannot fire you, demote you, or take any adverse action against you for exercising FMLA rights, filing a complaint, cooperating with an investigation, or testifying in a related proceeding.21U.S. Department of Labor. Fact Sheet 77B – Protection for Individuals under the FMLA
If your employer violates the FMLA, you can recover lost wages and benefits plus an equal amount in liquidated damages, effectively doubling the recovery. A court can also award attorney fees and order reinstatement or promotion. Employers avoid liquidated damages only by proving the violation was made in good faith with reasonable grounds for believing it was lawful.22Office of the Law Revision Counsel. 29 USC 2617 – Enforcement
Filing a Complaint in Ohio
If you believe your employer violated your FMLA rights, you have two paths. You can file a complaint with the U.S. Department of Labor’s Wage and Hour Division by calling 1-866-487-9243 or visiting your nearest WHD office. The agency can investigate and, if it finds a violation, bring a court action to compel compliance.23U.S. Department of Labor. How to File a Complaint Or you can file a private lawsuit directly.
The general statute of limitations is two years from the date of the violation, or three years if the violation was willful. For intermittent leave disputes, pinpointing the violation date matters because each denied absence or retaliatory action may start its own clock. Document everything: save emails, note the dates and times you called in, and keep copies of your medical certifications. In the disputes that go somewhere, paperwork is what separates a strong claim from a frustrating one.
