While the nation is enjoying its longest economic expansion on record and its lowest unemployment rate in 50 years, anxiety persists about how American businesses and workers will be affected by future changes in the labor market. Speculation about the "future of work" is typically centered on how new or emerging technologies could potentially change which skills are in demand, what jobs exist, which sectors will thrive or shrink, and how employee-employer relationships may shift. But changes in demographics and globalization, as well as in politics, culture, and society, will also be critical in determining where the world of work is headed. Public policy commentary on how to prepare for the uncertain future of work is neither new nor limited to the US. But given both potential opportunities and downside risks, as well as the long-term consequences of a failure to prepare, business leaders and policy makers must better position US workers to contribute to and share in growing prosperity in the years ahead. Today, efforts to better position US workers are being approached and funded in disparate ways. What is urgently needed is for public and private sector leaders to devise a comprehensive, collaborative strategy centered around forecasting skill needs, partnerships between business and academia, better matching supply and demand, job training, retraining, and upskilling. This report helps to lay out reasoned analysis and approaches for delivering a US job training system that more effectively helps workers achieve their goals and helps the nation field a more modern, highly skilled workforce.
