As my dad said...
..."I was looking for a job when I found this one." I've worked at over 20 different places, I've been laid off many times, and as long as I was flexible, I was able to find another job. I've never been on unemployment--there was always something available. Three things will help you: 1. Be flexible. The chronically underemployed people are what I call the not-willings: not willing to work weekends or evenings, or work in certain industries, or move where their prospects would be better. 2. Don't stay around too long. I recently quit a job after a day--I knew I was going to be unhappy there and it was going to be better for my employer. Staying makes the bad job the devil you know. Besides, if your performance is poor, you could end up being fired: your boss and your coworkers don't want to work with a complaining sad sack. 3. Do your best while you're there. It'll make the time go faster and you'll be more likely to leave on good terms.
