If you have been off work for up to 7 days, you do not need to see your GP for a Med3 Sickness Certificate, you may use an SC2 form (self-certification form).
You can download an SC2 form here – SC2-Form
If you are off work for longer than 7 days, your employer may ask for a Doctors Statement. To request, please complete an administration PATCHS, ensuring all of the relevant details including dates are noted.
If you have been in hospital during your sickness absence, the ward will provide you with a sickness certificate.
