Here is a document created by something called the Job Accomodation Network (ultimately part of the US Department of Labor) entitled "Employees with Asperger Syndrome". It looks like it could be very useful for employers who might not know much about AS. It's full of simple, specific suggestions for supervisors. This could be a great help for parents of young adults trying to ensure a positive first experience for someone with AS.
I found this via the PDF Search Engine. Just type in a term like "Asperger" and you will find all sorts of interesting things. You will need a PDF reader like Adobe Acrobat in order to view these documents.
