About this Sick Leave Email template
A sick leave email notifies; it does not ask permission. That is the real difference from a leave application, which requests planned time off in advance and can be turned down. Send yours as early as you can, ideally before the working day starts, and to whoever your policy names — many employers want the manager called and HR emailed, and a message dropped into a chat channel is not a record.
Keep it short and keep your diagnosis to yourself. “I am unwell and unable to work today” is a complete sentence and a complete explanation; you do not owe your symptoms to a group inbox. What genuinely helps is when you expect to be back, what is time-critical this week, and who can pick it up. Leave out the apology spiral, the promise to work from bed, and the martyrdom — offering to be “available all day” undercuts the whole message and teaches your team that your sick days are negotiable.
The common mistake is assuming one universal rule about sick notes and pay. Certification requirements, paid sick entitlement and how many days you can self-certify vary enormously by country, contract and employer. Check your handbook, and if you will be out more than a day or two, ask HR what they need rather than guessing.
Frequently asked questions
How much detail do I have to give?
Very little. Saying you are unwell and unable to work is enough; your health information is private and most employers neither need nor want the specifics.
Do I need a doctor’s note?
It depends entirely on where you work. Some employers require certification after a set number of days, others never ask, and the rules differ by country and contract — check your handbook or ask HR.
Should I check email while I am off sick?
You are off sick, so no. If you are well enough to hand one urgent thing over, a single short message is plenty — do not turn a sick day into a half day.
What about a mental health day?
The same email works — “unwell” covers it, and you are not obliged to specify. How much you disclose depends on how much you trust your manager and your employer’s culture.
What if I am still ill on my expected return date?
Send a short update before the day starts rather than letting the date pass in silence. A one-line message keeps things calm and keeps you in line with any absence policy.
