Probably not. First, find out if the law where you live covers you and your job (see the question just before this one). If it does, your company or boss can't change your job just because they're afraid of people with HIV. They can't change your job just because they think customers or co-workers are afraid of HIV. But, they can change your job if it's dangerous for you to do it. That means if you could infect other people, or if you could get hurt because of your HIV. But there aren't many jobs like that.
