Job security used to mean working at the same company for a lifetime and retiring with a well-funded pension. These days, the concept of a secure job has morphed into something much more fundamental: one that's less susceptible to layoffs.
That's obviously more likely if you're employed in an in-demand field. With the help of PayScale and Bureau of Labor Statistics data, AOL Jobs has compiled a list of the year's most secure jobs. The list includes a wide range of positions -- from those that require little training to highly skilled, professional jobs.
