By 2025, two million jobs will be unfilled because U.S. companies won't be able to find the skilled labor they need. Many of these jobs provide a middle-class salary — some pay six figures annually — and don't require a four-year degree. How to get one of these jobs? Apprenticeships. Economists and corporate leaders say they can lead to interesting and stable careers, ranging from robotics and mechanical design to medical sciences and high-end gourmet cuisine. Today, we explore finding an apprenticeship and the pros and cons. Our guests are Nicholas Wyman, author of "Job U: How To Find Wealth And Success By Developing The Skills Companies Actually Need;" Christine Scullion, director of human resources policy for the National Association of Manufacturing; Robert Lerman, founder, American Institute for Innovative Apprenticeship; Ken Hitchcock, director, Pickens County Career and Technology Center, Liberty, S.C.; and Cory McCray, electrician and member of the Maryland House of Delegates.
