How Long Should I Tolerate Poor Performance?

First, work out what kind of problem you actually have

Before deciding that somebody is a poor performer, ask: What exactly is not happening? Not:

“They're not stepping up.”

Not:

“They're not good enough.”

Not:

“They don't seem committed.”

What specifically is the gap? What was expected? What actually happened? What evidence do you have? Then ask the next question: Why? Because poor performance can have very different causes. It may be:

• unclear expectations;
• lack of skill; inadequate training; lack of authority;
• conflicting priorities;
• a broken process;
• insufficient resources;
• poor judgement;
• poor behaviour;
• lack of effort;
• or simply the wrong person in the wrong role.

Those are not the same problem. So they should not all receive the same response.

Clarify before you criticise

If the employee genuinely did not understand what success looked like, fix the clarity. If they have never been trained, train them. If they do not have the authority required to deliver, address that. If the system itself is preventing success, fix the system.

Managers have responsibilities here too. You cannot reasonably tell somebody they are failing to hit a target they were never shown. That is why I keep returning to the same questions: What did we agree? What did success look like? What actually happened? What is the evidence?

Only once those things are reasonably clear can you start having a meaningful conversation about responsibility.

Give support where support is genuinely needed

If the problem is capability, help build capability. If a manager has never had a difficult conversation before, coach them through one. If somebody has just stepped into a new role, give them room to learn. If knowledge is missing, provide it.

If they need practice, create opportunities to practise. That is development. But support should have a purpose. It should be helping the person become increasingly able to meet the standard without the same level of support. Otherwise support can quietly become compensation.

The manager starts doing parts of the employee's job for them. Colleagues start covering. Deadlines are continually moved. Expectations are watered down. And everyone begins pretending the situation is improving because the organisation has become better at carrying the gap. That is not development.

Ask whether anything is actually changing

This is one of the most useful questions in performance management. After the conversation... after the coaching... after the training... after the extra support... What changed? Not:

“Did we have the meeting?”

What actually changed? Is the result improving? Is the behaviour different? Are commitments now being met? Is the employee demonstrating the skill? Can you see movement? Development does not have to be instant. But there should eventually be evidence of it. If weeks and months pass with no meaningful change, that matters.

One missed commitment is not a pattern

Real life happens. Someone has a bad week. A customer crisis appears. An assumption turns out to be wrong. A deadline slips for a legitimate reason. Fine. Do not turn every miss into a character judgement. But one missed commitment and eight missed commitments are not the same thing. This is where evidence becomes so useful. Instead of saying:

“I feel like this keeps happening.”

you can say:

“Here are the last eight weeks. Here is what was agreed. Here is what happened.”

Now you can see the pattern. And patterns deserve management attention.

Repeated misses change the conversation

The first time, the conversation might be: What happened? The second time: What have we learned? The third or fourth time may need to become: Why is this still happening? Have we got the right expectation? Does the person have the skill? Do they genuinely understand what is required?

Do they have the authority? Are they avoiding something? Are they choosing not to prioritise it? Does this role fit them? At some point, the question is no longer:

“How do we help them with this one action?”

It becomes:

“What does this repeated pattern tell us?”

That is a different conversation.

Don't endlessly roll dates forward

I see this constantly. An action is due Friday. Friday becomes Tuesday. Tuesday becomes the end of the month. Then next month. The action survives indefinitely. Nobody wants to have the harder conversation, so they just keep moving the date. Eventually the date means nothing.

The action means nothing. And everyone watching learns: Commitments are optional here. If a commitment genuinely needs renegotiating, renegotiate it. But do it consciously. Why is the date changing? What has changed? What is the new commitment? What support is required? Then come back to it.

Do not use the calendar as a way of avoiding the underlying issue.

Non-negotiable has to mean something

Leaders sometimes love the phrase:

“This is non-negotiable.”

Be careful. If you call something non-negotiable and it repeatedly does not happen without consequence, you have not created a non-negotiable standard. You have created a suggestion with dramatic language.

If something genuinely matters, repeated failure eventually has to produce a different response. Perhaps more support. Perhaps formal warning. Perhaps reassignment. Perhaps a role change. Perhaps termination. The correct response depends on the circumstances and applicable employment obligations.

But what cannot continue indefinitely is pretending that an important minimum standard matters while demonstrating through leadership behaviour that it does not.

Think about who else is paying the price

This is the part leaders often miss. Who suffers when poor performance is tolerated? Yes, the business may lose money. Customers may suffer. Deadlines may slip. But there is another group paying the price: your good people. The reliable employees. The people who turn up.

The people who do what they said they would do. The people who care about the team. The people I call the GAF'ers — those who give a fuck. When somebody else continually underperforms, who usually picks up the extra work? Your good people. They cover. They stay back. They fix mistakes.

They absorb the customer problem. They compensate for the gap. And after a while, they start asking:

“Why do I bother?”

That is a dangerous question.

Tolerating poor performance can drive away good performance

Imagine being the reliable person on the team. You consistently do what is required. Someone beside you does not. You are regularly asked to cover. Leadership knows. Nothing really changes. What lesson do you take from that? Perhaps: The standard isn't real. Or:

Doing a good job simply earns me more work. Or: Leadership doesn't care enough to address this. Eventually your good employee may decide that another business will value their effort more. And then the person you lose is not the poor performer. It is the GAF'er who was carrying everybody else.

That is why leadership is not only about dealing fairly with someone who is struggling. It is also about protecting the people who are consistently doing the right thing.

Fairness is not endless tolerance

Managers sometimes worry that taking formal action is unfair. Fairness matters. Absolutely. People deserve clarity. They deserve a genuine opportunity to improve. They deserve proper support where support is needed. They deserve to understand the concern. But fairness applies to everybody.

It applies to the employee whose performance is being discussed. It also applies to: their colleagues; their manager; their customers; the business; and the people continually carrying the extra load. Endless tolerance is not automatically kindness.

Sometimes it is simply unfairness distributed across everybody else.

Don't wait for the annual review

Poor performance rarely improves because everybody quietly waits for the next formal appraisal. Address issues while they are manageable. Small conversations. Clear expectations. Evidence. Follow-up. If somebody misses an important standard, discuss it. If it happens again, come back to it.

Performance management should be a rhythm. Not one enormous annual ambush. Regular one-on-ones are useful because they allow issues to be seen early. What is working? What is not? What does success look like? What are you working on? What happened to the last commitment?

Now performance is being managed while there is still time to improve it.

Don't rescue the person from the consequences of their own gap

This one is uncomfortable. Managers often compensate. The employee misses a deadline. The manager stays late and finishes it. The employee avoids a conversation. The manager has it for them. The employee does not prepare. The manager prepares everything.

The employee cannot solve a recurring problem. The manager solves it again. Now the business keeps functioning. But what evidence do you have that the employee's performance has improved? Very little. You may simply have become excellent at hiding the gap. Support people.

But be careful about repeatedly removing the weight they are supposed to learn to carry.

Ask whether they give a fuck

There is a difference between someone who is struggling and someone who simply does not care. The person who cares usually shows you something. They try. They ask. They prepare. They tell you early when something is at risk. They respond to feedback. They make changes.

They may still make mistakes, but you can see effort and ownership. Someone else may continually wait to be chased. Offer excuses. Repeat the same behaviour. Show little curiosity. Take little ownership. At some point, effort and attitude become relevant evidence too.

This is what I mean when I talk about GAF'ers. People who genuinely give a fuck. They care whether their word can be relied upon. They care about the effect they have on everybody else. That matters enormously.

Use a clear improvement period

When a performance issue has become significant, do not let improvement remain vague. Agree: What specifically must improve? What evidence will demonstrate improvement? What support will be provided? By when should we reasonably expect to see movement? When will we review it?

Now both people understand the process. The period should be sensible for the issue. Some changes can be visible quickly. Others require practice. The important thing is that the improvement process itself has clarity. Not:

“Let's see how things go.”

What does that mean? Define the improvement you need to see.

Distinguish progress from completion

Someone may genuinely be improving without yet reaching the full standard. Notice that. If they are making meaningful progress, recognise it. The objective is not to engineer failure. It is to see whether the person can successfully perform the role.

But also do not confuse tiny gestures with meaningful improvement. Ask: Is the gap closing? Is the new behaviour becoming consistent? Can we reasonably see a trajectory towards the required standard? That is a much more useful judgement.

Sometimes the answer is the role

Not every performance issue is about somebody being a bad employee. Sometimes they are simply in the wrong role. A technically brilliant person may struggle in management. Someone who was excellent in a small business may struggle when the role becomes more structured.

Someone may be perfectly capable but poorly matched to the work. That still needs a decision. Could the role change? Is there a better fit? Can responsibilities be redesigned? Sometimes yes. Sometimes no.

But endlessly pretending someone will eventually fit a role they repeatedly cannot perform helps nobody.

There is no magic number of weeks

So how long should you tolerate poor performance? There is no universal answer. It depends on:

the seriousness of the gap; the role; the risk; the employee's experience; whether expectations were clear; whether training was adequate; whether improvement is happening; and whether the behaviour is within their control. A safety breach may require immediate action.

A newly promoted manager learning delegation may reasonably need time. A repeated refusal to follow a clear standard is different from somebody developing a complex new skill. The key question is not:

“Has enough time passed?”

It is:

“What does the evidence now tell us?”

Know when support has become avoidance

At some point, leadership has to make a judgement. We made the expectation clear. We provided support. We allowed reasonable time. We followed up. We collected evidence. The gap remains. Now what? Continuing exactly the same cycle is not neutral. It is a decision.

You are deciding to tolerate the current performance. And everybody else will experience the consequences of that decision. Leadership eventually requires choosing.
