Whether relating to abuse and harassment, or systemic doping, you may wonder how some issues remain open secrets in organizations where multiple stakeholders know about a problem or a concern, but no one publicly brings it up.

To address this phenomenon, leaders must encourage stakeholders to speak up, change organizational culture that encourages passing the buck, and reward acts of individual courage.
