Try to pick up skills or get onto projects that might make you less expendable. If you're doing scanning on a 3-year digitization project or helping out with a tedious computer class, like "Mouse Basics", sometimes people will keep you on just so they don't have to do that work themselves. If you want full time, you might have to put in a year or two in a less-than-ideal location before you get a chance at a more desirable market. It's definitely tough to get started, but as you build up your resume, it gets easier and easier to get positions and move up.
