4.3 High Performance Shouldn’t Mean High Exhaustion:

Rethinking How We Work and Measure Success

There’s a pattern that shows up across many organisations. It’s often unspoken. Sometimes even rewarded.

The more someone works…

The more they take on…

The more they stretch themselves…

The more they’re seen as “high performing.”

But over time, something starts to shift.

What looks like performance…

Begins to look more like:

• long hours becoming the norm
• constant availability
• difficulty switching off
• increasing pressure to keep up

And in some cases:

12-hour days become routine

14-hour days become familiar

Even 15–16 hour days are no longer unusual

And this is where we need to pause

Because working at that level - consistently - isn’t sustainable.

The issue isn’t commitment

It’s not ambition. It’s not work ethic.

It’s the assumption that:

More hours = more value

But in reality

Research and experience across organisations show that:

• performance declines with fatigue
• decision-making becomes less effective
• creativity reduces under pressure
• errors increase over time

In other words:

The very thing we’re trying to maximise…starts to decrease.

This is where a different perspective is needed

Instead of asking:

“How much can this person take on?”

We should be asking:

“What level of performance can this person sustain?”

Connecting the principles

In earlier articles, we explored:

• Lean methodology
  → removing unnecessary work
• Agile methodology
  → creating clarity and focus

Sustainable performance builds on both.

It’s about:

• reducing unnecessary demand
• clarifying priorities
• and designing work in a way that can continue over time

Where organisations often get it wrong

There’s sometimes an unspoken trade-off:

“We can’t reduce their workload right now…”

“But we still need them to take this on…”

So what happens?

The work doesn’t disappear

The expectations increase

And the gap is filled by personal time

Even if unintentionally.

The role of messaging — and what gets reinforced

Another factor that often goes unnoticed is the messaging around performance. Not just what is said explicitly — but what is reinforced through outcomes.

When someone takes on additional responsibility and delivers quickly…

It’s often seen as a positive

The output is valued- praised even

The pace is accepted

But what isn’t always visible is how that output was achieved.

In some cases:

It’s being done through extended hours

Through working beyond what’s sustainable

Or by using personal time to meet expectations

And over time, this can create an unintended signal:

That working longer is what leads to recognition

That going beyond capacity is what gets results

That this level of effort is expected — even if it’s never formally stated

This becomes more complex if it’s known

If organisations are aware that this is happening…

…and continue to accept the output without adjusting expectations…

The pressure shifts entirely onto the individual

Even if unintentionally.

Sustainable performance requires aligned messaging

It’s not just about designing roles well.

It’s about ensuring that:

What is rewarded

What is recognised

And what is expected

Are all aligned with what is actually sustainable.

Because without that alignment…

The system encourages behaviour that cannot be maintained long-term

The risk

Over time, this leads to:

• burnout
• disengagement
• reduced retention
• and loss of potential

And often, it’s not immediate

It builds slowly. A late evening here. An extra few hours there. Until it becomes the norm.

A more sustainable approach

Sustainable performance doesn’t mean lowering standards.  It means designing work differently.

What this looks like in practice:

1. Defining realistic capacity. Not theoretical — actual.

2. Designing roles around sustainability. Not just output.

3. Recognising effort without normalising overwork. There’s a difference.

4. Creating space for recovery and reflection. Not just constant delivery.

Final thought

High performance shouldn’t come at the cost of wellbeing. 

And long-term success isn’t built on short-term overexertion.

It’s built on consistency.

Clarity.

And sustainability.
