First of all, congratulations ! Good for you! Your manager will probably be surprised at first if she doesn't suspect, but will then probably offer you her best wishes. It's by trying different things that you'll be able to learn about them, as well as learn where you want to be 20 years from now. I was worried about that when I first started trying different specialties, but over the years the comments became more and more positive about "all the experience I have".

It's really a win-win situation for all involved.
Best Wishes,
Sue
