What name of note from the doctors to say, that you are unit to get a job or work long term

The document you are referring to is typically called a "medical certificate" or "fit note." In some regions, such as the UK, it is specifically known as a "fit note" (also referred to as a Statement of Fitness for Work). This document is issued by a healthcare professional and serves to indicate whether an individual is fit to work or if they require adjustments to their role due to health reasons. If the doctor believes that the individual is unfit for work long-term, they may specify that in the note.
