Germany has a concept called Krankschreibung.
Literally: sick writing. A doctor's note that says you cannot work.
When that note lands on your employer's desk, it is not a request. It is a legal shield.
Your boss cannot fire you. Your boss cannot demand you come in. Your boss cannot call you during your recovery.
In some countries calling in sick feels like asking permission. In Germany it is stating a medical fact.
That is not just good labor law. That is human decency. 🇩🇪
