Job for acquaintances?

I'm currently looking for a light office job for my friend. He is, I believe, very mentally handicapped, in the past he had a pronounced speech disorder and as far as I know he went to a special school, later to a secondary school. He has an apprenticeship as a qualified office worker. He lives very withdrawn and is very shy, can imagine that he would rather work alone than in a team.

Which light office activities would be suitable for him? He can handle the PC, is enthusiastic about console games (Nintendo, XBOX, Playstation), but has difficulties in dealing with people. He seems tense and nervous when talking to people he does not know.

Then he can only work from home

The employment office will certainly be happy to help

There goes the chance to 0

Letters are light office activities

where you do not have to think, just write on dictaphone or something
