James Detert, a professor at the University of Virginia Darden School of Business, studies acts of courage in the workplace. His most surprising finding? Most people describe everyday actions — not big whistleblower scandals — when they cite courageous (or gutless) acts they’ve seen coworkers and leaders take. Detert shares the proven behaviors of employees who succeed at speaking out and suffer fewer negative consequences for it. He’s the author of the HBR article “Cultivating Everyday Courage.”
