Every team has them. The unwritten rules that nobody enforces and nobody questions and that silently determine what gets said, withheld and who feels safe enough to contribute fully.

These aren’t the rules in the employee handbook, they’re older than that. They come from family, from culture, from every room a person had to learn to navigate before they got to yours. And according to Denise Soler Cox, they are the single most under diagnosed source of performance loss in organizations today.

Denise is an award-winning filmmaker, keynote speaker, and author of the forthcoming Simon & Schuster book What Will They Say? Her keynote gives leaders a framework for doing something most organizations have never attempted: naming the hidden rules that are running their culture, understanding where those rules came from, and deciding deliberately, together, which ones still serve the team and which ones are costing it.

The result is not a belonging initiative. It is a performance intervention. When people stop spending energy on managing the gap between who they are and who they think they need to be at work, that energy goes somewhere else. It goes into ideas, into collaboration, into the kind of contribution that doesn’t show up when people are performing instead of participating.

Cox has delivered this keynote to audiences ranging from 4,000 attendees at the annual convening of Meeting Professionals International to employees to intimate leadership offsites, and the response is consistent: leaders leave with a new diagnostic for what’s actually happening on their teams, and people leave feeling like something that had been unnamed finally has a name.
