I've found out about a job that could very well be opening up soon in a district that I'm interested in. The position hasn't been posted yet, but I've been told to be proactive and apply early. I'm planning on contacting HR and the principal, but how do I go about doing it? In other words, how do I say, "I hear that there might be a position opening soon," without saying that? It's been five years since I've job hunted, so I'm a little rusty.
