The Cost of Keeping Poor Performers Too Long and Why This Is the Moment Leaders Need to Act

In Edition 8 we explored why top performers are beginning to look outward. The conversations that followed made something else clear: retention is only half the equation. The other half, the one leaders rarely discuss openly.. is the cost of keeping poor performers in senior roles for longer than the organisation can afford.

So what is a “poor performer”? This doesn’t just mean the obviously failing leader, it also means those who are underperforming.. the one who is fine, but not good enough for where the business needs to go next.

Every CEO and MD knows the feeling of having a senior leader who is capable enough to avoid immediate intervention, but not strong enough to drive the business forward. Someone who delivers just enough to stay in post, but not enough to raise standards. Someone who absorbs time, energy and attention that should be directed elsewhere. Someone who is not failing, but is certainly not leading.

And because the past three to five years have been defined by volatility, perhaps many organisations have tolerated this dynamic for longer than they would have in a more stable market. Although the risk of change can often feel greater than the cost of inaction.

1. The Real Cost of Keeping Poor Performers Too Long

They drain the energy of your top performers

High performers do not leave because of workload; they leave because of standards. When they see weaker leaders being protected, carried or excused, their confidence in the organisation erodes. This is the link back to Edition 8: retention risk is often created by the people you keep, not the people you lose.

They slow decision making at the exact moment the market requires pace

Poor performers rarely make catastrophic decisions. Instead, they make slow ones. They create drag, ambiguity and organisational friction that compounds over time and becomes visible only when it is removed.

They lower the bar for those beneath them

When a senior leader operates below the required standard, the layers beneath them recalibrate their own expectations accordingly. This changes the culture all within their leadership.

They block progression for stronger people who are ready for more

One of the most common frustrations among top performers is the sense that their next step is being held back by someone who is not delivering at the level required. This is where retention and performance management intersect most sharply.

They absorb disproportionate leadership attention

CEOs and MDs often spend more time managing around a poor performer than developing their strongest people. The opportunity cost is significant, and rarely acknowledged.

2. The Red Flags That Signal It Is Time to Act

These are the patterns CEOs and MDs mention most often when they know, deep down, that a senior leader needs to move on:

• You are spending more time managing around them than leading through them.

• Their team is performing despite them, not because of them.

• You have lowered the standard of what “good” looks like to accommodate them.

• You hesitate before giving them anything critical because you’re unsure how they will handle it.

• You are having more conversations about their behaviour than their impact.

• Your strongest people avoid involving them in work that matters.

• You cannot articulate a credible future for them that aligns with where the business is going.

• You would feel relief, not loss, if they resigned.

Leaders often describe these red flags as “manageable”, but manageable is not the same as acceptable and it is certainly not the same as strategic.

3. Why CEOs Delay the Decision (And Why They Shouldn’t)

Because the individual is loyal

Loyalty is valuable, but it cannot compensate for capability.  And loyalty from the wrong person can cost you loyalty from the right ones.

Because the market has been unstable

This was a legitimate reason for caution between 2021 and 2024.  It is less legitimate now.

Because the replacement feels like a risk

The greater risk is allowing the organisation to coast.

Because the individual is not failing but just not leading

This is the hardest and most damaging category, because it’s the easiest to tolerate.

4. Why This Is the Moment to Make the Change

The market is selective, not slow so the best candidates are not applying; they are being approached.
The organisations that will move fastest in the next cycle are the ones that have the courage to upgrade their leadership now, not when performance forces their hand.

A well‑run executive search is not about replacing a problem.  It is about raising the standard of the leadership environment so that your strongest people can operate at the level the market now demands.

A Closing Observation

Underperformance at senior level is often a gradual loss of momentum that and becomes part of the background until the cumulative effect is impossible to ignore.
