Your health and wellbeing are actually improved if you can stay at work during your recovery, or if you can return to work as soon as possible.
You don't have to be fully recovered or to have finished medical treatment before you can go back to work. In fact
- a complete recovery is not often achieved before return to work
- the longer you are away from work, the less chance you have of ever returning
- work is generally good for your health and wellbeing
