This is a guide for those who want to leave a positive environmental impact at their workplace by becoming an employee activist. It offers tools, not just inspiration, providing employee activists with insights into how power works and how change spreads. “This timely and hopeful guide reminds us that change begins within, showing how employees, through everyday actions, can shape the culture, pace, and purpose of the transition our world needs.” Sophie Lambin, Founder and CEO of Kite Insights and creator of Hurd "A wake-up call for everyone who believes real change can only come from the top. This book shows how every employee can become a catalyst for transformation – turning frustration into action and workplaces into engines of sustainability. It’s both practical and deeply empowering.” Ingmar Rentzhog, Founder and CEO of wedonthavetime.org “Offers actionable strategies and tactics while underscoring a simple truth: when employees organize, they can transform the future.” Maren Costa, tech-worker organizer, climate-justice advocate and Board President of Amazon Employees for Climate Justice "This book helps us tap into the positive values we want to work from.
