Book excerpt: Most learning on the job is informal. This book offers advice on how to support, nurture, and leverage informal learning and helps trainers to go beyond their typical classes and programs in order to widen and deepen heir reach. The author reminds us that we live in a new, radically different, constantly changing, and often distracting workplace. He guides us through the plethora of digital learning tools that workers are now accessing through their computers, PDAs, and cell phones.
