Leadership is What You Tolerate: What Are You Allowing?

“The culture of your team is not defined by what you preach, but by what you allow.”

Leadership isn’t just about vision, strategy, or motivation—it’s about boundaries. The behaviors you tolerate, whether consciously or unconsciously, shape the culture of your team more than any speech or mission statement ever could.

The Silent Culture Builders

It’s easy to think that team culture is created by what we actively promote. But in reality, the culture is shaped just as much—if not more—by the things we let slide.

Consider these scenarios:

• A team member consistently shows up late, and nothing is said. Soon, others do the same.

• Negative attitudes creep into meetings, but they go unchallenged. Morale drops.

• Performance expectations lower over time because poor results aren’t addressed.

It happens subtly. But over time, a lack of action becomes an endorsement.

 

The Data Tells the Story

– A Harvard Business Review study found that leaders who tolerate toxic behaviors see a 25% drop in team productivity and a 40% increase in turnover.
– According to a study by McKinsey, 70% of workplace culture is driven by leadership behavior—both what is actively encouraged and what is passively tolerated.

What does this mean for you? Every action—or inaction—has consequences.

 

Your Leadership Audit: What Are You Allowing?

Take a moment to reflect:
1. What behaviors are currently happening in your team that you would rather not see?
2. What excuses have you made for not addressing them?
3. What one thing will you commit to no longer tolerating?

Great leaders set the tone—not just with the

ir words, but with their actions. If you want a culture of accountability, excellence, and respect, you must be willing to address what threatens it.
