Ed Stack, the chief executive of Dick's Sporting Goods, decided after the Parkland school shooting to pull assault rifles and high-capacity magazines from all of his company’s stores. The controversial choice hurt revenues. But the retailer weathered the storm, thanks to inclusive and thoughtful decision- making, careful communication with all stakeholders, and a strategic shift to new product lines. Stack explains why he chose to take such a public stance on a hot-button social issue and how it has affected him personally and professionally.
