Coping with Asperger's in the workplace
I work with people who have Asperger's Syndrome every day and have had no major problems at all.  The reason is that I do indeed follow some documented strategies, particularly those outlined in "Working with a Person with Asperger’s Syndrome" (Autism Victoria, 2007). A brief list of strategies suggested by that document suggest that workers with Asperger's Syndrome need:


consistency  
predictability
a calm and controlled supervisor (this also applies to coworkers)
an organised workplace


Most of all, don't make a big deal of their condition, just be aware of what is needed.
