Firm, Not Harsh

Gentle Assertiveness: A Manager’s Real Power

There comes a moment in a leader’s career when they realise something uncomfortable: raising your voice doesn’t increase your authority; it only raises the noise.

Somewhere along the way, “being firm” started to be confused with sounding sharp, intense, or unapproachable. And yet, the most respected leaders, the ones people follow even in silence, rarely sound harsh. They don’t pressure. They don’t intimidate. They don’t rush to prove their position.

They speak clearly. They decide calmly. And their firmness lands with more weight than any loud tone ever could.

This newsletter is about that shift: the moment when authority stops coming from intensity and starts coming from clarity. The moment when you no longer need to push to be heard because the way you speak already carries enough presence.

If you’ve ever wondered why harshness gets compliance but firmness gets commitment, or why your calm voice has more impact than your strongest argument, then this edition is for you.

The Blind Spot

When most leaders step into their first management role, they cling to a simple belief: authority is something you show. So they speak more firmly, sit more upright, and adopt a “managerial” tone. And for a while, it works. Teams respond because they’re still looking at the role, the stance, the seriousness.

But something subtle happens as leaders grow into more senior positions — and many never notice the shift. At higher levels, people no longer respond to tone. They respond to clarity, emotional steadiness, and the quiet confidence behind a decision. The room listens not because you sound firm, but because you are anchored.

And this is where the blind spot begins.

Some senior managers keep using the same tools that served them early in their career: intensity, pressure, and a sharpened tone meant to create urgency. They may not be harsh by nature. They’re simply leaning on the behaviours that once delivered results.

But at senior levels, harshness no longer signals authority. It signals strain. It reveals the moments when the mind is tired, when expectations outpace clarity, when a leader tries to regain control through volume rather than presence.

Many grew up in cultures that whispered, as “serious business requires a serious tone.” Yet the reality of modern leadership tells another truth:

Harshness makes people defensive.
Firmness makes people aligned.

Harshness gets the quick nods, the quiet room, the superficial yes. Firmness earns the kind of commitment that holds even when you’re not in the room. And for a senior leader, it is commitment - not compliance - the real measure of influence.

What “Firm, Not Harsh” Actually Means

Every leader says they want to be “clear and firm,” but only a few can describe what firmness actually looks like in practice. Most people confuse it with intensity: a sharper tone, a tighter posture, a sense of pressure that fills the room. But firmness is not a performance. It’s a discipline.

The leaders who master it do something counterintuitive: they reduce force to increase impact. Firmness is quiet. It’s measured. It’s deliberate. It doesn’t need to rush, justify, or dominate. Harshness, on the other hand, is reactive. It often looks like a spike of emotion disguised as decisiveness.

The difference is visible immediately:

     Firm leaders speak in short, clean sentences.

     They say exactly what needs to be said, nothing more.

     Harsh leaders push for control.

     They add pressure because clarity hasn’t done its job.

     Firm leaders create boundaries without apology.

     Their consistency makes people feel safe.

     Harsh leaders create tension, at times even without meaning to.

     Their intensity shifts the focus from the issue to the reaction.

     Firm leaders think while they speak.

     You can feel the stability underneath their words.

     Harsh leaders speak before they think.

     You can feel the urgency of someone trying to regain footing.

Managers often confuse showing a tough character with behaving in a pushy, noisy or even bullying way. Only to understand later that people fear them instead of respecting them. Because people always follow clarity.

What many leaders discover is that the moment they lower their voice, their team starts listening with twice the attention. Not because the message changed, but because the energy behind it did.

The Psychology Behind Gentle Assertiveness

“Strong leaders don’t raise their voice; they raise their standard.”

Firmness doesn’t overpower. It aligns. It removes confusion, not confidence. It resets direction, not dignity. And most importantly, it gives authority a new dimension, one that doesn’t need volume to be heard.

Why does this work so powerfully? Because the human brain is wired to thrive in stability and to fight back, fight or freeze under acute stressful intensity.

When a leader speaks with calm firmness, something shifts in the room. People stop scanning for danger and start scanning for direction. Their nervous system relaxes enough to access reasoning, not defending. And suddenly, your message lands with clarity instead of resistance.

A calm leader creates a calm mind in others, and calm minds make better decisions.

Harshness, however unintentional, disrupts that equilibrium. It triggers micro-defensive reactions: people shut down, become transactional, avoidant, resistant, ultra-competitive, or purely complacent without engaging their intelligence. They may do what they are asked, but they disconnect from the bigger purpose. This is the survival behaviour. Strategic reaction for survival in the jungle, but utterly non-strategic for collaboration within any organisational environment.

This is the way the human brain prioritises safety (survival) over anything else (i.e. a management meeting where consensus should be reached). And to be effective, leaders need to know how they employ human psychology.

Firmness does the opposite. It sends a signal that the leader is anchored, thinking clearly, and not threatened. That safety gives people permission to contribute, challenge, and collaborate at a higher level. 

Senior executives often underestimate this dynamic because they imagine authority as an external asset (a tone, a stance, a way of taking space). But true authority is internal regulation made visible. The more stable you are inside, the more influence you project outside. This is why gentle assertiveness is not soft, it’s not passive, nor a compromise.

This is the psychological advantage of a leader who can stay composed while others escalate. In time that composure becomes contagious: it cascades through teams, shapes culture, and elevates performance.

A harsh tone may force silence. But a calm, firm presence changes how people think in your presence. And this, more than any loud instruction, is the signature of a truly senior leader.

But How to Be Assertive and Remain Gentle?

Beyond being an attitude, gentle assertiveness is a set of behaviours that can be practised, refined, and strengthened. And once you learn them, you realise something surprising: firmness is not effortful. It’s efficient.

Here are five senior-level behaviours that create firmness without even a hint of harshness:

1. Use direct language, delivered in a warm tone.

Firmness doesn’t require dramatic phrasing or narratives. It requires precision.  Instead of: “Why isn’t this done yet?” Say: “I need this by 4 pm. What’s required to make it happen?” You remove pressure and replace it with clarity that invites responsibility.

2. Speak in shorter sentences.

And stop explaining so much. Harshness creeps in when the leader over-talks. Firmness appears when the leader knows exactly where the sentence ends. The more concise you are, the more authority your words carry.

3. Set boundaries without emotional packaging.

A boundary is not a negotiation; it is information that looks like this:

“This meeting ends in 20 minutes.”
“I’m not available for this today.”
“I need you to own the next steps.”
No justification. No apology. The consistency, not the tone, creates respect.

4. Hold your line calmly, even when challenged.

Pressure tests your real authority. Anyone can be firm when everyone agrees. A senior leader is firm when the stakes rise and emotions climb. The moment you raise your voice, you give away your power. The moment you stay anchored, the dynamic shifts in your favour.

5. Replace emotional pressure with structural clarity.

When leaders feel under stress, they unintentionally use tone to create urgency. High-level firmness avoids this trap by using structure instead of emotion: clear deadlines, defined ownership, explicit expectations, and decision checkpoints. Structure makes people act. Tone makes people react.

A technique elite leaders use:

Lower your voice. Raise your impact. When a senior leader speaks more quietly, teams listen more closely. Calm creates gravity. Confidence creates silence. And silence creates space for authority to land.

The paradox of firmness: When you stop trying to sound firm, you finally become firm. When you stop pushing for respect, people start giving it freely. Because what they feel in your presence is certainty.

Final word

The real difference between being firm and being harsh is not linguistic; it’s neurological. A leader who can self-regulate under pressure naturally speaks with clarity, stability, and intention. A leader who cannot will instinctively lean into intensity, even when the words are correct. Self-regulation is the internal architecture that supports mature authority: it keeps your thinking available when others shut down, it keeps your tone steady when complexity rises, and it gives your decisions a weight that no volume can imitate.

This is why senior leadership is not a test of skills, but a test of presence. Your impact is decided not at the moment you speak, but in the half-second before, in the internal pause where you choose clarity over impulse, direction over reaction, and firmness over harshness. When that space collapses, tone takes over. When that space expands, authority becomes effortless.

And this brings us to a more honest question:
How well do you know your own internal space?

If you want to assess whether this capability is an area for growth, here are five questions designed to make the invisible visible:

1. In moments of pressure, do I respond or do I react?
2. Does my presence calm the room or amplify its tension?
3. How often do I raise my tone instead of raising my clarity?
4. Do people follow my direction because they trust my steadiness or because they want to avoid my intensity?
5. Where in my leadership do I rely on force instead of self-regulation to create alignment?

These aren’t performance questions. They are awareness questions, and awareness is the inflexion point where senior leaders grow beyond their own patterns.

If these questions revealed tension, curiosity, or an inner “yes, this might be me,” then this is the exact work I help senior managers strengthen: the shift from emotional reactivity to strategic self-regulation, from intensity-powered leadership to presence-powered influence.
