I Need Advice

So I work with a gal who is extremely rude and insensitive. She is the "Program Coordinator" for our area and works with all of the staff, balancing vacation days, sick days, and staffing the rooms that are without a teacher. I realize her job is difficult and she deals with whiners and wimps who call in sick at the drop of a hat, but I am not one of those people. I am always at work. I rarely call in sick. I am a nice person who focuses on doing my job and giving my best every day. I was sick this past weekend with a stomach virus, and told by the nursing supervisor I could not come to work Monday despite feeling well. (They have to have the strictest of rules about viruses as we work with the vulnerable population of elderly adults.) So now I'm on the PC"s black list. I called her at home (her policy) to tell her I wouldn't be at work Mon. She was rude on the phone to me, even as I pointed out that it wasn't my choice to stay home. I really think she shouldn't be in a position where she works with people (since she seems to dislike people so much.) What is the best way to deal with her?
