Book excerpt: Underpinned by the fact that the globalization process and the subsequent increased level of market uncertainty have paved the way for employment flexibility in modern societies, this book examines the labor market chances of young adults in the US and in ten European societies over the past three decades. As young adults represent a very vulnerable labor market group, flexible and insecure employment tends to be pronounced especially at labor market entry. The contributors therefore explore which groups of young adults are especially affected by increasing employment insecurities.
