You don’t need to explain your symptoms, justify your stress level, or share a diagnosis. Calling out for a mental health day is, in most workplaces, no different from calling out sick. A short, professional message to your manager is all that’s required. The part that feels hardest, finding the right words and hitting send, is simpler than you think once you know what you’re actually obligated to share (very little) and what you’re not.
What to Say When You Call Out
Keep your message short, professional, and focused on logistics. You don’t owe anyone a detailed explanation of how you’re feeling. Here are some straightforward options that work over text, email, or a quick phone call:
- “I’m not feeling well enough to work today, so I need to take a sick day. I appreciate your understanding.”
- “I need to use a personal/sick day today as I am unwell. Thank you for your understanding.”
- “I need to take a sick day today. I expect to be back tomorrow. Please let me know if you need anything else.”
If your workplace culture is open about mental health, you can say “mental health day” directly. If it’s not, “sick day” or “not feeling well” covers it completely. Neither version requires follow-up details. The word “unfortunately” at the start of your message softens the tone without over-apologizing.
For email specifically, a version like this works well: “Unfortunately, I am not feeling well enough to work today and need to take a sick day. I appreciate your understanding. I expect to be well enough to work by [tomorrow/date], depending on my recovery. I’ll make sure to keep you updated. Please let me know if you need any other information.” That’s the entire email. Subject line: “Out sick today.” Done.
You Don’t Have to Share a Diagnosis
One of the biggest barriers to calling out is the fear that you’ll be asked to explain what’s wrong. Legally, your employer has limited ground to push for specifics. Under the Family and Medical Leave Act, employers can request a healthcare provider’s certification to support the need for leave, but a diagnosis is not required. The certification just needs to show enough information to support the need for time off, not name your condition.
Your employer is also prohibited from disclosing or threatening to disclose information about your mental health condition to discourage you from using leave. Medical records related to your absence must be kept confidential and stored separately from your regular personnel file. The ADA and other federal laws reinforce these protections.
In practical terms, this means if your manager asks “What’s going on?” a response like “I’m dealing with a health issue and need the day to recover” is a complete answer. You’re not being evasive. You’re exercising a normal boundary.
Recognizing When You Need One
Most people who search for how to call out already know they need the day. But if you’re second-guessing yourself, certain patterns signal that pushing through will cost you more than pausing. Are you dragging yourself to work and struggling to start tasks? Have you lost patience with coworkers or clients in ways that feel out of character? Is it genuinely hard to focus, not just boring but cognitively difficult?
Physical signs matter too. Unexplained headaches, stomach problems, disrupted sleep, and feeling physically drained without a clear medical cause are all ways your body registers emotional overload. If you’ve started numbing with food, alcohol, or scrolling just to get through the evening, that’s another clear signal. The point of a mental health day is to interrupt the cycle before it becomes a longer problem, not to wait until you’re in crisis.
Timing and Logistics
Notify your manager as early as possible, ideally before your shift starts or at the beginning of the workday. The same window you’d use for a stomach bug applies here. If your company has a formal call-out system (an HR portal, a specific phone number), use it the same way you would for any other sick day. Text or email is fine if that’s how your team normally communicates absences.
Before you sign off, handle the basics quickly: flag any urgent deadlines, set an out-of-office reply if needed, and let a teammate know if something time-sensitive needs coverage. This isn’t about earning permission to rest. It’s about making the day genuinely restorative instead of spending it anxious about loose ends.
If You Work Remotely
Taking a mental health day when your office is also your living room requires deliberate separation. The temptation to “just check one email” can erode the entire purpose of the day. Close your laptop, silence work notifications, and physically step away from your workspace.
Research on remote work well-being suggests creating clear transitions helps your brain register the shift. Change out of whatever you’d normally wear while working. Step outside, even briefly, at the start of your day off. These small rituals create a boundary that remote work otherwise blurs. The goal is to be fully off, not half-working from the couch, which leaves you neither rested nor productive.
Making the Day Actually Count
A mental health day isn’t just a day off. It’s a reset, and how you spend it matters. Lying in bed doom-scrolling for eight hours might feel like rest in the moment, but it rarely leaves you feeling better. Instead, aim for a mix of genuine rest and low-effort activities that recharge you: sleep in if you need to, go for a walk, cook a meal you enjoy, spend time outside, or do something creative with no stakes attached. The bar is low. You’re not trying to solve your burnout in a day. You’re trying to break the momentum of exhaustion.
Avoid using the day to run errands, clean the house, or catch up on personal admin. Those things are productive, but they don’t address the mental load that made you need the day in the first place. Protect the hours for activities that feel restorative rather than obligatory.
When One Day Isn’t Enough
A single mental health day works well for acute stress, a rough week, a bad night, or the kind of emotional fatigue that sleep and stillness can meaningfully dent. If you’re taking mental health days frequently, or if one day off barely makes a difference, that’s a signal of something deeper than a bad week.
Persistent feelings of emptiness, ongoing loss of motivation, or the sense that your work has no value are hallmarks of burnout, which doesn’t resolve with a day off. At that point, the mental health day was the right first step, but it points toward bigger changes: a conversation with a therapist, a serious look at your workload, or an honest assessment of whether the job itself is sustainable. The day off buys you the clarity to figure out which of those comes next.
