Why Culture Change Fails—and How Leaders Can Actually Drive It

Earlier in my career, I worked for a global company. I passed my manager in the hallway and wanted to ask a question. She was stressed and cut me off before I finished speaking. I tried again. She interrupted once more. On the third attempt, I said, “Can you please be quiet until I have finished my question?” She stopped. I completed my question. She answered and rushed away. Five minutes later, I did the exact same thing to one of my own team members.

That moment has stayed with me for decades. It wasn’t dramatic, but it was embarrassing. I’d like to think I’ve learned from it. Yet even the best intentions can slip back into old habits. Most leadership communication failures are unconscious.

And here’s the hard truth: you can’t train culture away. Culture isn’t something you fix with values workshops, culture decks, or offsite strategy days. It’s too abstract. Culture emerges from thousands of daily conversations—in meetings, hallways, and one-on-ones—and shapes how people behave, day after day.

How Communication Drives Culture—and Results

Communication shapes behavior. Behavior drives results. That’s the sequence.

Every instruction, presentation, piece of feedback, or hallway exchange—whether stressed or friendly—moves people toward a desired behavior or away from it. If you want to know the true state of an organization—its culture, energy, and direction—listen to its everyday conversations. Strategy documents reveal leadership intent. Conversations reveal what’s actually happening. And every conversation either builds or breaks engagement.

The Link Between Engagement, Communication, and Performance

Engagement is the bridge between communication and behavior. When people feel genuinely engaged, they act because they want to, not because they have to. That’s the difference between high performance and quiet quitting.

Yet global employee engagement has declined. In 2024, it fell from 23% to 20%—the second drop in twelve years, matching the decline seen during the COVID-19 lockdowns. Manager engagement dropped even more sharply, from 30% to 22%, over the same period.

Here’s the concerning pattern: the people most responsible for driving team engagement are themselves disengaging. The ripple effect is clear. Gallup’s data shows that 70% of the variance in team engagement can be attributed to the manager. In other words, the single largest lever for organizational performance is how the team leader communicates.

Highly engaged teams deliver measurable results: a 23% increase in productivity and a 51% reduction in turnover compared to disengaged teams.

The Three Communication Superpowers of High-Performing Leaders

After two decades working with leaders across industries and continents, I’ve identified three capabilities that set apart those who build high-performing cultures from those who erode them. I call them the Three Communication Superpowers.
