As evilkimevil, said, it is best to get a job where you work alone.
I'm really sorry to hear this is happening to your daughter, and I've been through this a couple times, and it's terrible. It blows knowing that everyone but you fits in fine at work, everyone's buddy buddy, and you're just the "weird girl" no one talks to (my first job at a grocery store, also known as HELL).
I've found that the key is to a)work with as few people as possible, and most importantly b)to find a reasonable, down to earth boss. Short of that, if I were your daughter I'd quit. But that's just me. Most people wont change opinions like that, and there usually isn't a way around those situations. If it's of any consolation, I'm only 19 and so far I've found two bosses that were carefree, reasonable, accommodating, and accepting, which is just beautiful. I clean banks right now... I make good money, work alone with my fiance, and my boss treats us amazingly.
What I really want to say is "sue that b****es pants off", but that's pretty unrealistic. I wish the best for you and your daughter, and just remind her that there are people with AS who both enjoy their jobs and make a decent living. The key is to be patient and understanding, not hard on yourself, when looking for the right job for you.
