The research on successfully returning to work after TBI doesn't tell us a great deal beyond returning to your old job and the degree of injury are two important factors.
Headway has fantastic information concerning returning to work.
I wonder have you succeeded, if so what difficulties did you experience in the workplace and did you use the Headway guidance.
I ask because I offered to have a chat with a friend's friend who was returning to work but they sent a message saying they had worked there for 13 years and they were an Equal opportunity employer so he was confident it would be fine.
Now 6 months later I've just been told it was a disaster, off with stress and eventually resigned. I also understand his "friends" had been the worst part taking against him causing depression and hence off with stress.
Of course that appears scary but I also know of some great success stories, did it work for you?
