Phil walked out of the meeting feeling pretty good. He had buried the new CEO under a mountain of data and a mile-long list of his wins as President of the distribution arm of a large investment firm. Mission accomplished. Territory defended.
A week later, he was packing his desk. He asked his team to stay quiet as he left. His second-in-command was down the hall getting fired at the same time, and Phil wanted to reach his car without another conversation.
The rebuild took 18 months. New head of distribution. New management team. New strategy. The organization stagnated as the work to repair it progressed.
Here is the part Phil never saw.
The behaviors that got him to the presidency are actually the same behaviors that walked him out the door. Thorough. Hard-driving. Fluent in data. On a normal Tuesday, those traits made him effective. The day a new CEO arrived, something else shifted under him. He needed to feel secure in his role. He needed to know his standing was not in question.
But when those needs went unmet, his usual strengths intensified.
His thoroughness became overwhelming. In being data-driven, he became defensive under stress. And his confidence became combativeness.
The CEO saw a leader under stress whose behavior felt guarded, territorial, and uncomfortable with direct feedback.
Leaders have always operated in a VUCA environment: volatile, uncertain, complex, and ambiguous. Markets shift quickly. But with the heightened integration of artificial intelligence, the world is changing even faster and more dramatically.
AI transformation is altering workflows, decision rights, and business outcomes. Organizational change is no longer a discrete initiative. It is the operating reality many teams inhabit every day.
That is why change fatigue has become a defining leadership challenge.
Change fatigue is not simply resistance to change. It's the cumulative strain, disengagement, and depletion that can set in when people absorb too much workplace change too quickly. It affects employee engagement, mental health, organizational culture, and performance.
For leaders, the risk is personal. In uncertainty, behaviors that once created success can become liabilities. Strengths do not disappear under pressure. More often, they become louder, more rigid, and harder for others to navigate.
At Birkman, we often see that people do not become entirely different under pressure. They become amplified versions of themselves. The same behaviors that help someone succeed can create friction when underlying needs go unmet.
Behavior is what others see. Needs are what sustain the behavior.
Stress Behavior is often what emerges when that need goes unnoticed for too long.
That is the human dimension of change management and is why leadership self-awareness is essential to leading through change.
Practice 1: Know Your Baseline Behavior
Phil’s first failure happened earlier, on the ordinary Tuesdays when he never paused to name the way he worked.
Pressure did not change Phil’s behavior as much as it magnified it. The baseline stayed the same, but the volume increased. He could not feel the difference because he had never defined the starting point.
Many leaders assume their behavior is obvious because it feels obvious from the inside. But behavior often looks different from the outside, especially to a team member experiencing it in a high-pressure moment.
A leader may believe they are creating clarity when they are actually creating pressure. They may think they are moving decisively when others experience impatience. They may believe they are strengthening the management process, while the team experiences scrutiny.
Leadership self-awareness begins with naming observable patterns. Not “I am strategic,” but “I move fast and ask questions later,” or “I look for data before making a decision.”
What to do this week: Write down the three behaviors you default to on a calm, productive day. Ask two colleagues whether the description matches what they see. When work feels heavy, return to the list. If your behavior has become sharper, faster, more controlling, or more withdrawn, that shift may be your earliest warning signal.
Practice 2: Know What Fuels You
Phil walked into that meeting needing security in his role and confirmation that his standing was not in question.
He never said either out loud.
Underneath behavior is need. The need is not a weakness. It is the fuel.
When the fuel is present, your Usual Behaviors work for you. When the fuel runs low, those same Behaviors can begin working against you.
Phil’s need for security met a CEO who was assessing the team. The fuel ran dry. His response was self-protection dressed as preparation.
This is why managing change fatigue requires more than communication plans, timelines, and management strategies. Effective change management also requires leaders to understand what people need to stay engaged and productive through uncertainty.
People do not move through change as job titles. They move through change as human beings with distinct needs, stress patterns, and thresholds for ambiguity.
One team member may feel energized by possibility. Another may need clear expectations. One person may want autonomy. Another may need reassurance before moving forward.
The mistake is assuming everyone needs the same thing from change.
When needs remain unspoken, they often surface as Stress Behavior. A team member who needs clarity may appear resistant. A leader who needs respect may become combative. An employee who needs time to process may seem disengaged.
What looks like resistance is often an unmet need trying to get attention.
What to do this week: List three things that energize you and three things that drain you. Ask which list has shown up most in the last 30 days. Then ask the same question of your team. Leaders who understand those differences are better equipped to build trust, support employees, and protect employee engagement.
Practice 3: Know Your Stress Tells
By the time Phil walked into the meeting, the tells were already loud.
He just could not hear them.
Thoroughness became overwhelming.
Data-driven became defensive.
Confident became combative.
Every leader has stress tells. The settings differ, but the pattern holds: strengths under stress often do not disappear. They overrun the room.
A leader’s Stress Behavior becomes part of the team’s working environment. A leader who becomes controlling may reduce problem solving. A leader who withdraws may leave employees without context. A leader who moves too quickly may create confusion.
This is how leadership in uncertainty can either build resilience or drain it.
That matters during AI transformation and other workplace change, where ambiguity is high and the path forward may keep changing. Teams look to leaders for cues about how to interpret change.
- Is this manageable?
- Are we safe enough to ask questions?
- Can we name what is not working?
- Is continued improvement part of the culture?
Leaders answer those questions through behavior.
What to do this week: Identify your three stress tells. Then build a reset protocol: a walk before a difficult conversation, a pause before a triggering email, or a team norm that allows people to say, “We may be reacting from stress right now.”
Leading Through Change
Phil walked out of a building.
You walk into work on a Monday.
Same setup, different ending, if you are willing to do three things he never did:
- Know your baseline behavior.
- Know what fuels you.
- Know your stress tells.
That is the work of VUCA leadership: not pretending uncertainty does not affect you, not forcing your team through change with more pressure and less recovery, and not relying only on a process when the real issue is human.
The real work is learning to see behavior clearly, understand the needs beneath it, and respond before Stress Behavior becomes the culture.
For 75 years, Birkman has helped leaders and teams understand the human dynamics that shape performance, collaboration, and change. Usual Behavior, underlying needs, and stress responses are foundational to The Birkman Method.
