You mean autistic employee, singular.

Whether the behaviour "comes from" his autism or not should not have any bearing on how you deal with it. (This is not legal advice)

Do you not have a code review step to prevent bad code from entering the repository?

OP didn’t say he was the one responsible for bad code. Autistic here probably means that he seems better than most people and most engineers can’t compete with his output
