Sick certificates can be provided, if medically appropriate, for employment purposes only.
For the first calendar week of an illness a patient can sign a self certification form (SC2) which can be obtained from his/her employer. Following this period, if it is appropriate, an NHS certificate is needed which has to be signed by your GP for any further absence from work due to illness.
As from April 2010 these have changed slightly and are now called Fitness to work Certificates. This allows your Dr to suggest possible alternatives to being off work such as light duties or a phased return to work. These will be discussed with you where appropriate and can then be used as a guide for your employer although it does not bind your employer to offering such options.
We are not required to provide sick notes in your self certification period and we are not able to provide sick notes for non medical problems. More guidance about sick notes is available through the link below.
