If you're off work sick for seven days or less, your employer should not ask for medical evidence that you've been ill.
If you're off work sick for more than seven days, your employer will usually ask you to provide proof that you've been ill. They will normally ask for a fit note from your GP. Fit notes may also be called medical statements or a doctor's note.
The seven days includes days that you don't normally work. When you work out how long you've been off sick, you should include weekends and bank holidays.
Sickness of seven days or less:
Your employer can ask you to confirm that you've been ill. You can do this by filling in a form yourself when you return to work. This is called self-certification.
Self-certification forms usually include details such as:
•information about your sickness or illness
•the date your sickness started
•the date your sickness ended
These dates may be days that you don't normally work. For example, your sickness could start or end on a Saturday, Sunday or bank holiday.
Some employers may request a fit note from employees who repeatedly take time off sick, even if each time they're off work it's for seven days or fewer.
For sickness of seven days or fewer, your GP practice may charge you to provide a fit/sick note as this would be considered a private sick note.
