This is definitely interesting. While I don't have an exact answer for you I can tell you just 2 days ago that my boss found out I am an alcoholic through a conversation we were having. She then related to me that she and her partner are both alcoholics also. Then we had a long conversation about alcoholism. I was afraid of her finding out and then it came to pass that she and I weren't so different after all and she is the last person to judge me.
I guess, in my opinion, that it isn't something to be ashamed of since you are actively seeking recovery. I can't believe that someone would hold it against you, but then I can't speak for what other people think or what not. I am sure someone that is more knowledgeable with come along with a better answer. Thought I would relate my experience because something I feared in my head turned out to be just that - in my head!
