Anytime I hear "we have a shortage of workers" my first thought is, "for what jobs, and at what wage/working conditions?"
Usually when a person says "I have a shortage of workers" they mean "I can't find enough chumps/desperate people to work for the ridiculously low wage I want to pay."
There is also the difference between jobs and careers. For many it is not enough to have a job that pays decently. They need one that is stable. Preferably with benefits that can make future planning easy. (And, by easy, I mean possible.)
