People like this -- and I've known several -- are suffering from an acute case of knowing their situation perfectly well. They know that they don't warrant the salaries they're receiving for the work they do. They fight against any improvement to their systems because the inefficiency is their job security. They feel constantly threatened because they understand that people coming up behind them just don't need them. That's why their nervous and irritable. The biggest problem with these folks is that they grew old between the ears, and think they can't adapt to their changing circumstances. If they would, they could learn to be more valuable in other ways.
