An occupational health doctor or other doctor responsible for your care assesses the need for rehabilitation and issues a statement including a recommendation for vocational and medical rehabilitation: in other words, rehabilitation to improve functional capacity, and the doctor advises you on how to apply for different benefits.
The occupational health doctor is familiar with your illness, conditions at your workplace and the demands of your job, and assesses the need for rehabilitation within the earnings-based pension scheme. It is usually necessary to arrange a joint meeting where the employee, supervisor, personnel management representative and occupational health doctor and nurse assess work arrangements and agree on trial work when necessary.
An occupational health nurse can help you to fill in an application for rehabilitation.
