There isn’t a recommended set amount of time to take off work, it very much depends on when you feel ready. Try not to rush going back to work and give your body time to recover. You may find that some symptoms, like fatigue, resolve themselves after the first month.
The amount of time you take off may be influenced by the sick leave you get from your employer and other financial considerations.
If your job involves driving you must not drive for at least one month. Visit the driving page for more information.
Talk to your employer about a gradual “phased” return to work to ease yourself in gently.
