One of the life lessons the universe seems determined to teach me, over and over again, is the importance of boundaries.

Just when I think I’ve mastered them, another situation presents itself. A client request arrives at an inconvenient time. A commitment expands beyond what was originally agreed. A relationship becomes unbalanced. Or I find myself saying “yes” when every part of me knows I should have said “not this time.”

Perhaps you can relate.

Many leaders I work with are exceptionally capable, committed and caring. They take pride in being reliable, responsive and available. Yet these very strengths can become liabilities when boundaries are absent.

The challenge is that poor boundaries rarely show up as a dramatic event. They creep in gradually. One late-night email becomes a habit. One extra responsibility becomes five. One difficult conversation avoided becomes a source of frustration and resentment.

Before long, we find ourselves exhausted, overwhelmed and wondering why leadership feels so heavy. All of the above I have learnt the hard way, so my gift to you is how to read the warning signs and what you can do about it before choices are limited and there is little to no fuel left in the tank!

Why Boundaries Matter in Leadership

When people hear the word “boundaries”, they often think of saying no or creating distance. In reality, healthy boundaries create clarity.

They help others understand:

• What is expected
• What is acceptable
• Where responsibilities begin and end
• How we work best together

Research consistently shows that clear boundaries contribute to psychological safety, accountability, trust and sustainable performance. When leaders communicate expectations clearly and model healthy limits, teams experience less confusion, greater ownership and reduced risk of burnout.

A Harvard Business Review article on leadership effectiveness highlights that leaders who establish clear expectations and priorities create greater focus and reduce unnecessary stress within teams. Similarly, workplace wellbeing research consistently identifies poor boundary management as a significant contributor to employee burnout.

In other words, boundaries don’t weaken leadership.

They strengthen it.

Yet if you are anything like what I was, you are asking what boundaries are? It’s almost something no one (until recently) has talked about, and how to set healthy boundaries has not been part of the Leadership Programs I delivered before 2020!

The Oxygen Mask Principle

A great metaphor for boundaries is the airline safety briefing.

“Put your own oxygen mask on before assisting others.”

We hear it every time we fly, yet many leaders operate in the exact opposite way. (Me included!)

We take care of everyone else’s needs first.

We respond to every request.

We absorb every problem.

We carry everyone else’s emotions.

And then we wonder why we’re running out of energy ourselves.

Strong leaders understand that boundaries are not selfish. They are a responsibility.

Because the quality of your leadership is directly linked to the quality of your energy, focus and well-being.

A Lesson from Brené Brown

Researcher and author Brené Brown captures this beautifully:

“Daring to set boundaries is about having the courage to love ourselves even when we risk disappointing others.”

Many leaders fear that boundaries will disappoint people.

Yet what I’ve observed is the opposite.

When leaders consistently communicate what is and isn’t okay, what they can and cannot commit to, and what standards they expect, people often trust them more—not less.

Predictability creates trust.

Clarity creates confidence.

Consistency creates respect.

What Boundaries Look Like

Leadership boundaries are not only about protecting personal time.

They show up in:

• Saying not at the minute to work that doesn’t align with priorities.
• Refusing to tolerate behaviours that undermine team culture.
• Clarifying decision-making responsibilities.
• Protecting time for strategic thinking.
• Not rescuing team members from every challenge.
• Being clear about what support you can and cannot provide.
• Creating space for recovery and wellbeing.

Every boundary sends a message about what matters.

And every boundary you fail to set teaches others what they can expect from you, which turns into the new baseline expectation, the new normal.

How Do I Set Boundaries?

Here’s something I have found helpful in setting boundaries

Not all boundaries are created equal. Psychologists often describe boundaries as falling into three broad categories: rigid, porous, and flexible.

Reflection for Leaders

When under pressure, many of us move away from flexible boundaries.

Some become more rigid, withdrawing and controlling.

Others become more porous, taking on too much and trying to rescue everyone.

The invitation is to notice your default response.

When stress increases, do you build walls or open the gates?

The most effective leaders don’t have the strongest boundaries. They have the most adaptable ones.

They know when to lean in, when to step back, and how to protect what matters without disconnecting from the people they lead.
