The Leadership Blind Spot That Allows Bullies to Thrive

Most of us have encountered them at some point in our careers. The colleague who undermines others behind closed doors, the person who quietly manipulates relationships, the one who seems to leave a trail of frustrated teammates while somehow continuing to advance.

We tell ourselves that eventually the system will correct itself, someone will notice, and the behavior will catch up with them.

And yet, surprisingly often, it doesn’t. In fact, workplace bullies sometimes thrive.

At first glance, that seems difficult to explain. But when you look closely at how organizations actually function, the pattern begins to make more sense.

Several years ago, I compared this dynamic to something gardeners understand well.

Gardeners often choose plants like ivy or other hardy varieties because they can survive almost anything: flooding, drought, poor soil, unpredictable weather. When conditions become difficult, these plants continue to grow while more delicate varieties struggle.

In the short term, this can seem like a smart choice. Hardy plants ensure the garden survives.

But over time, those same plants begin to dominate the space. They spread quickly, block the sunlight, and crowd out more thoughtful, balanced growth.

Workplace dynamics can unfold similarly.

Research published in the Journal of Managerial Psychology found that workplace bullies often receive strong performance evaluations and achieve significant career success. The reason is not necessarily that leaders support bullying behavior. More often, it is these individuals who possess strong social and political awareness. They know how to manage perceptions upward while directing very different behavior toward peers or subordinates.

In other words, they are strategic. Clever. Conniving.

They rarely create visible conflict for the leader who oversees them. Their behavior tends to occur out of view, behind the scenes, and in moments where it is difficult for others to prove or explain what is happening without sounding like whiners.

This creates a difficult dynamic for leaders.

Many leaders genuinely dislike conflict. Complaints about interpersonal behavior can feel messy and ambiguous; one person’s experience versus another’s interpretation. It requires investigation, emotional energy, and sometimes uncomfortable decisions.

By contrast, individuals who behave aggressively toward peers often present themselves to leadership as loyal, dependable, and fiercely committed to the organization’s success. They rarely bring problems to their manager’s door. Instead, they appear calm, capable, and unbothered when complaints about their behavior surface.

In uncertain environments, that kind of apparent stability can be appealing.

Like the hardy plant in the garden, they seem to thrive during difficult conditions. But allowing this dynamic to continue comes with long-term costs.

Over time, environments dominated by intimidation, manipulation, or quiet hostility begin to push out many of the people organizations need most - those who contribute thoughtfully, collaborate generously, and focus more on collective success than personal advancement.

Healthy teams depend on trust, psychological safety, and the ability to challenge ideas without fear of retaliation. When those conditions disappear, innovation and resilience tend to follow.

There is another irony as well.

Individuals who manipulate systems for personal advancement are rarely loyal to any single

leader or organization. Their primary loyalty is to their own trajectory. If circumstances change and a more advantageous opportunity appears, they will move just as strategically toward the next source of influence. And when that happens, the same behaviors once directed at others may eventually be directed upward.

The lesson for leaders is not simply to eliminate difficult personalities. Every organization contains strong personalities and ambitious individuals. The real challenge is recognizing the difference between strength and intimidation, between loyalty and manipulation, and between confidence and control.

The most resilient organizations are not the ones that tolerate the toughest personalities. These are the ones that create environments where people can do their best work without fear, where healthy disagreement is encouraged, and where leadership is measured not only by results, but by the culture those results create.

Because in the long run, the health of the garden depends on more than which plants grow the fastest.

It depends on which ones allow everything else to grow as well.
