Answer: Your insurer may coordinate what is known as a graduated return to work program with your employer. A graduated return to work is a schedule that gradually increases the number of hours and days you work until you reach full time hours and days at work.
Usually your insurer will write to your treating physician to get approval for the graduated return to work plan.
If the graduated return to work plan and returning to work increases your symptoms and you are unable to continue working, you must provide supportive medical evidence to your insurer. If you are unable to participate in the program entirely, you would also need to provide supportive medical evidence, which has to show that your symptoms would be made worse if you participated.
