What is a Medical Certificate in Belgium?
A medical certificate (also known as a sick note or certificate of incapacity for work) is a document issued by a doctor confirming that a person is temporarily unable to work due to illness or injury. If you are sick and cannot resume work or attend classes, these medical certificates let you avail leaves without any further delays. So head on to our website and apply now!
When Do You Need a Certificate?
Sick Leave
| Absence Duration | Requirement |
|---|---|
| Day 1 | Inform employer |
| Day 2+ | Medical certificate required |
If you don’t feel good for one day, informing your employer is more than enough. This is termed as self-certification and is suitable if you are calling out for a sick leave on day 1.
However, when you see that your health is not getting better and you realise you might need an extended leave, a medical certificate is required to ensure your employer has knowledge of the same. Having a medical certificate also ensures that you receive sickness benefits via health insurance.
