I've been with the same organization for about six years now and I've decided it's time for me to move on. I've done well in my time with them and I've been promoted 4 times and am ended up in a reasonably senior role. The only problem is I'm doing a technical role in a public service organization that's in a very small niche. For that reason, I'm worried about the marketability of my "skills" in any context other than one I've spent the last six years working in. Has anyone ever been in a similar scenario? Is there any advice anyone can offer?
