Book excerpt: Everything about work changed in 2020. Billions of people were sent home from the office, unsure of what they'd be coming back to, or when. Organizations crammed decades of transformation into weeks. And every leader was asked for the same, impossible thing: clarity. Bestselling authors and management experts Johnathan and Melissa Nightingale capture a year of leadership lessons, from the first COVID lockdowns to the first anniversary. Unmanageable is the definitive read on how it felt to adapt, reinvent, and lead during the most tumultuous time in a generation. From the early chaos, to unending burnout, and the unprecedented turnover that followed, the pandemic laid bare the cracks in the old rules of work. Unmanageable introduces the new rules, and offers a practical and essential guide for what comes next.
