" The sound that surrounds a successful regimen of one-on-ones is silence. All of the listening, questioning, and discussion that happens during a one-on-one is managerial preventative maintenance. You’ll see when interest in a project begins to wane and take action before it becomes job dissatisfaction. You’ll hear about tension between two employees and moderate a discussion before it becomes a yelling match in a meeting. Your reward for a culture of healthy one-on-ones is a distinct lack of drama.
