In the not-too-distant past, the scenario of unemployment dipping below 5 percent was unthinkable. Well, think again. It's nightmare time in the human resources department. Finding and keeping good employees has never been a higher priority than it is right now, and all indicators show it's not going to get better. With more than 76 million baby boomers either opting out early or poised to take the retirement plunge starting in 2011, and 20 million fewer Generation Xers stepping into the breach, employment is extremely tight. This series explores how to recruit and, perhaps more important, how to retain great employees. It investigates strategies for identifying and meeting the needs of businesses as well as the needs of shifting generations, and it shows how those needs can be met with a creativity and sensitivity that considers not only the human factor but also the bottom line.
