You can self-certificate yourself for the first 6 days of any absence from work through illness. Self-certification forms are available from either your employer or any DSS office. They are particularly appropriate for minor illnesses which do not necessitate a visit to your GP.
It is also possible in some circumstances for your doctors to issue a fit note without using up an appointment, ie. if you are already under care of the hospital. The receptionist will be able to discuss this with you; this may save both you and the doctor time. Hospital doctors and nurses can, where appropriate, also issue fit notes.
You can also request fit notes via eConsult. Please click here to access this service.
