Worse yet, I am almost five years older than when I last was in the available labor pool. Back when I first got into computer networking as a career, that five years would have made little or no difference. Today, however, I'm finding that it is a significant barrier to re-employment. No, potential employers do not come right out and say, "You're too damned old." Rather, they apply the label of "over-qualified" for whatever position you are seeking.
One would think that qualifications beyond their stated minimums would be an advantage, since they would be getting a more capable worker for lower wages. But, no, they're afraid that you will "jump ship" at the first opportunity for higher wages. Perhaps this fear is rationalized by their past experiences. However, as they have no past experience with me personally it is, at best, a form of prejudice.
