I'm always hedging against my current employer by having a public presence and building my personal brand. I don't need to be rich. But I want to have a job I like and work on interesting work. If my current employer has layoffs, my boss is bad, or I have to deal with some crappy situation - I'm always in a position to leave. I like to regularly interview (well really 'take calls/offer advice/talk to people') and get into the habit of advertising my skills. During a recession this is more important than ever...
