You don’t need a lengthy explanation or a doctor’s note to tell your boss you have a migraine. A brief, direct message that states what’s happening and what you need is the most effective approach. The key is framing it around your work plan, not your symptoms, so the conversation stays professional and productive.
What to Say in the Moment
When a migraine hits during the workday, keep your message short and focused on logistics. Your boss needs to know three things: that you’re dealing with a health issue, how it affects your availability, and what your plan is for your current responsibilities. You don’t owe a detailed description of your symptoms.
A straightforward message might look like this: “I’m experiencing a migraine and need to step away for the rest of the day. I’ve finished [task] and will follow up on [task] tomorrow morning.” If you’re hoping to push through with some flexibility, try something like: “I’m dealing with a migraine right now. I can keep working on [priority task], but I may need to take a break or work from a quieter space if symptoms get worse.”
Text or email often works better than a phone call or face-to-face conversation when you’re in pain. It also creates a record, which matters if you ever need to document a pattern for leave purposes. If your workplace culture expects a phone call for sick days, keep it to 30 seconds. You’re not asking permission to be sick. You’re informing your manager of the situation.
Why “Migraine” Is Worth Saying
Many people default to “I have a bad headache” because it feels less dramatic. But this actually works against you. A headache sounds like something you can push through with a couple of ibuprofen. A migraine is a neurological condition, and using the correct term helps your boss understand why you can’t just power through it.
Migraine is a brain disorder involving disrupted sensory processing. During an attack, normal light becomes painful, routine sounds feel unbearable, and even moving your head can intensify the pain. About 14% of the global population experiences migraine, so there’s a reasonable chance your boss either has personal experience with it or knows someone who does.
If your boss seems skeptical, one useful clarification: migraine isn’t caused by stress or a low pain threshold. It’s an inherited neurological condition that temporarily changes how the brain handles sensory input. You don’t need to deliver a biology lesson, but a single sentence like “Migraine is a neurological condition I manage, not just a headache” can shift the conversation.
Having the Bigger Conversation
If migraines affect your work more than once or twice a year, it’s worth having a separate, proactive conversation with your boss outside of an active episode. This is very different from the in-the-moment notification. You’re setting expectations and building a plan so future absences don’t catch anyone off guard.
Choose a calm moment, ideally during a regular one-on-one or a scheduled check-in. You might say: “I want to let you know that I manage a chronic migraine condition. Most of the time it doesn’t affect my work, but occasionally I’ll need flexibility, like working from home or adjusting my schedule on a difficult day. I wanted to be upfront so we can plan for it.”
This framing accomplishes several things at once. It positions you as responsible and solution-oriented. It normalizes the occasional disruption before it happens. And it opens the door for accommodations without making it feel like a formal HR complaint. Research on migraine self-management in the workplace consistently shows that employees who have supportive supervisors and some control over their tasks and environment manage their condition far more effectively at work.
Dealing With Stigma
Workplace stigma around migraine is real. Studies on migraine self-management find that many employees feel their condition is dismissed as trivial, that colleagues expect full performance whenever they’re physically present, and that the invisible nature of the condition makes it harder to be taken seriously. Some people avoid disclosing entirely because they’ve been brushed off before.
The most effective counter to stigma is consistency. If you say you’ll make up the work, make it up. If you say you’ll be back tomorrow, be back tomorrow. Over time, your track record speaks louder than anyone’s assumptions about migraine. People with migraine lose an estimated 10 productive days per year to the condition, between missed days and days where productivity drops by half or more. That’s significant, but it’s also manageable when your employer understands the pattern.
If a particular coworker or manager is dismissive, you don’t need to convince them migraine is real. Redirect the conversation to work output: “I understand it’s inconvenient. Here’s my plan for making sure nothing falls through the cracks.” You’re not seeking sympathy. You’re managing a logistics problem.
Accommodations You Can Request
If migraine substantially limits your ability to work, you may be entitled to reasonable accommodations under the Americans with Disabilities Act. You don’t need to be disabled in the traditional sense. The standard is whether the condition substantially limits a major life activity, and chronic migraine often qualifies.
The Job Accommodation Network, a resource funded by the U.S. Department of Labor, lists several specific accommodations for migraine that have proven effective in workplaces:
- Flexible scheduling to allow for late starts or early departures during an attack
- Remote work options so you can manage symptoms in a controlled environment
- Modified break schedules to rest in a dark, quiet space when symptoms escalate
- Alternative lighting such as anti-glare filters on fluorescent lights or task lighting instead of overhead fixtures
- Noise-canceling headphones or sound-absorbing panels to reduce auditory triggers
- Cubicle shields or doors that provide a semi-private space to limit sensory input
To request accommodations formally, you typically go through HR rather than your direct manager. Your employer can ask for medical documentation from your healthcare provider confirming the condition and the need for adjustments. They can’t ask for your full medical history or details about your treatment.
FMLA Leave for Chronic Migraine
If you work for an employer with 50 or more employees and you’ve been there at least 12 months, the Family and Medical Leave Act may apply. FMLA provides up to 12 weeks of unpaid, job-protected leave per year for serious health conditions, and the U.S. Department of Labor specifically names migraine as a qualifying condition.
What makes FMLA especially useful for migraine is that the leave doesn’t have to be taken all at once. You can use it intermittently, taking individual days or even partial days when an attack prevents you from working. Your employer can require a healthcare provider’s certification to support the leave request, but once approved, you’re protected from being penalized for those absences.
This matters because one of the biggest fears around telling your boss about migraine is the accumulation of sick days and the perception that you’re unreliable. FMLA intermittent leave creates a formal framework that separates migraine absences from your general attendance record.
What Not to Disclose
You’re not obligated to share your medication list, your migraine frequency, your triggers, or your full medical history. During hiring, employers can’t legally ask about disabilities or health conditions at all. Even after you’re hired, you only need to share enough information to justify the specific accommodation or leave you’re requesting.
If your boss asks intrusive questions out of curiosity rather than malice, a simple redirect works: “I’d rather keep the medical details private, but I’m happy to talk about how we can make the work schedule function when I have a bad day.” This keeps the boundary clear without creating conflict.
