How Do I Stop Good Employees Becoming Frustrated by Poor Performers?

Good people notice unfairness very quickly

Strong employees are usually not asking everybody to be perfect. They understand that people learn. Mistakes happen. People have bad weeks. What frustrates them is a repeated pattern where one person contributes less and everyone else quietly compensates.

Especially when leadership appears to do nothing about it. They notice: who misses deadlines; who gets away with poor behaviour; who never prepares; who is always rescued; who carries the extra work. And they notice whether the manager notices.

Poor performance creates hidden redistribution

When somebody does not do their share, the work rarely disappears. It moves. A customer still needs an answer. The order still has to ship. The report still needs completing. The shift still needs covering. So somebody else carries it.

That redistribution is often invisible on the organisational chart. But employees know exactly who is carrying whom.

Your most reliable people are at particular risk

The strongest employees often make the problem less visible. They care about the result. So they compensate. They pick up the slack. That may protect the business in the short term. But it also enables management to avoid dealing with the original performance problem. Eventually the strong employee learns:

“If I am reliable, I get more work.”

That is a terrible lesson to teach.

Do not punish competence

This happens more often than leaders realise. A manager thinks:

“Give it to Sarah. She’ll get it done.”

Yes. She probably will. Again. But if Sarah continually receives the work other people fail to complete, reliability becomes a punishment. Be careful. Your best people should not become the organisation’s permanent shock absorbers.

Ask who is carrying the extra weight

When somebody is underperforming, ask:

“Who is compensating for this?”

That question often changes the urgency of the issue. Perhaps another employee is staying late. Perhaps a manager is doing work that belongs to their team. Perhaps another department is constantly fixing errors. Now you can see the real cost.

Fairness does not mean identical performance

People have different experience. Capability. Development needs. That is normal. A new employee may need more support than an experienced one. Fairness is not everybody producing exactly the same thing.

Fairness is the organisation responding appropriately to the different situations rather than indefinitely pretending a clear performance gap does not exist.

Define the standard

Before judging poor performance, make sure expectations are clear. What should the person be doing? What does good look like? What is the agreed standard? Without that, frustration can become subjective. Your high performer may think:

“They’re useless.”

Perhaps. But management needs more than irritation. Clarify the standard. Then compare behaviour and results with it.

Use evidence

Do not manage from:

“Everyone thinks they’re underperforming.”

Track what matters. Missed deadlines. Errors. Attendance. Commitments. Customer impact. Required behaviour. Now you can determine whether there is actually a pattern. Evidence protects everybody. Including the employee being assessed.

Distinguish one bad week from a pattern

A good employee can have a bad month. Someone can make a mistake. Do not overreact. But repeated misses tell a different story. That is why evidence over time matters. One incident deserves curiosity. A repeated pattern deserves management.

Address the gap early

One reason good employees become frustrated is that managers wait far too long. They notice the issue. Say nothing. Hope. Compensate. Wait. Then everyone else spends months living with a problem management already knows exists. Have the smaller conversation earlier.

“This is what we agreed.”

“This is what happened.”

“This is the gap.”

“What do you think is going on?”

Much better than letting resentment build.

Support genuine improvement

Poor performance does not automatically mean somebody should leave. Perhaps the person needs: clarity; training; better priorities; more authority; different resources; coaching; or a reasonable opportunity to improve. Provide that where appropriate. Good people can see the difference between genuine support and endless avoidance.

Do not let support become compensation

There is a point where help becomes something else. The manager constantly fixes the work. Colleagues cover. Deadlines are extended. Standards are lowered. Now the organisation is not supporting improvement. It is compensating for the absence of it. Ask:

“Is this person becoming more capable because of the support?”

If not, the conversation needs to change.

Tell the difference between progress and completion

Someone may genuinely be improving. Recognise that. But improvement does not automatically mean the required standard has been reached. Be clear about both.

“This is better.”

And:

“This is still the gap.”

That is fairer than either ignoring progress or pretending partial improvement has solved the issue.

Protect confidentiality without pretending nothing is happening

Other employees do not need the details of someone's performance-management process. But that does not mean leaders must behave as though they have noticed nothing. You can say:

“I am aware of the issue and I am dealing with it.”

Then actually deal with it. What frustrates employees is often not the lack of private detail. It is apparent leadership inaction.

Do not turn high performers into the performance police

Your strongest employee should not have to manage the weaker one by proxy. They can give appropriate feedback. Help. Coach. But the formal accountability belongs with the manager. If colleagues are constantly trying to enforce standards management is avoiding, something is backwards.

Watch resentment before it becomes disengagement

A strong employee may not complain immediately. They just keep doing the work. Then something shifts. Less enthusiasm. Less willingness to help. More cynicism. Perhaps:

“Why should I stay late? Nobody else does.”

That is important information. Do not dismiss it as a bad attitude without asking what produced it. “Why do I bother?” is a dangerous sentence When your reliable people start thinking this, leadership should pay attention. They may still be performing. For now.

But psychologically they are beginning to detach. Eventually another employer may offer them an environment where standards feel fairer. And then the person you wanted to keep leaves while the person whose work they were carrying remains. That is a poor outcome.

Poor performance can lower the standard for everyone

People watch what happens. If repeated non-delivery has no consequence, the practical standard changes. Employees learn:

“Apparently this is acceptable.”

Some will maintain their own high standard anyway. Others will adjust downward. Why work harder than the organisation actually requires? That is how tolerated poor performance spreads.

Your response teaches the culture

This links directly to culture. You may say:

“We value accountability.”

But what happens when somebody repeatedly does not deliver? You may say:

“We value teamwork.”

But what happens when one person continually leaves the team carrying their work? Your response teaches what the business really values.

Do not confuse kindness with avoidance

Having an honest performance conversation can be uncomfortable. Managers sometimes avoid it because they want to be kind. But what about the people carrying the extra work? What about the customer? What about the employee themselves, who may have no idea how serious the gap has become? Clarity can be kinder than prolonged ambiguity.

Good employees need to see that standards mean something

They do not need theatrical punishment. They need evidence that: commitments matter; poor behaviour is addressed; reliable performance is recognised; and the same basic standards apply consistently. That creates trust.

Recognise the people doing the right thing

This matters enormously. Reliable employees can become invisible because they create few problems. Don't let that happen. Notice: the person who prepares; the person who keeps promises; the person who warns you early; the person who helps the team; the person who consistently delivers. Say:

“I see it.”

Recognition is not a substitute for dealing with poor performance. You need both.

Do not let recognition become “Here’s more work”

This is an easy trap. Every time someone performs well, they receive another difficult task. Development opportunities are good. Permanent workload dumping is not. Ask whether your reward system actually feels like a reward.

Look at workload distribution

If one person is underperforming, examine what has happened to workload across the team. Has someone else inherited: more customers; more admin; more shifts; more responsibility? Make those effects visible. Otherwise management may underestimate the real cost.

Sometimes poor performance is actually wrong-role performance

A person may be trying. They care. They are simply in a role that does not suit their capability. That is different from somebody who does not care. The answer may be: training; role redesign; a different position; or eventually a different decision. But leaving somebody indefinitely failing in the wrong role is not kind to them or the team.

Effort matters, but results matter too

You can appreciate someone's effort and still recognise that the role requires an outcome they are not achieving. “They try really hard” cannot be the entire performance standard. Likewise, a person producing the number while damaging everyone around them may also be a performance problem. Performance is broader than a single result.

Ask whether they give a fuck

I use the term GAF'er for someone who gives a fuck. That does not mean they never struggle. It means you can see care. They prepare. They try. They respond to feedback. They flag risk. They take responsibility. If somebody is underperforming but genuinely engaged in improving, that matters. If they repeatedly show little ownership despite support, that also matters.

Make improvement expectations specific

Do not say:

“You need to improve.”

Improve what? By how much? By when? What evidence will show it? What support will be provided? When will you review it? The clearer the improvement expectation, the fairer the process is for everybody.

Put a timeframe around improvement

Endless informal coaching creates uncertainty. If there is a genuine performance gap, agree a review period. What needs to change? What will demonstrate progress? When will you look again? There is no universal magical number of weeks. The right period depends on:

seriousness; risk; role; experience; training needs; and how quickly change could reasonably be visible. But there should be a point at which you review the evidence.

Good employees notice endless rollover too

If every performance conversation ends: “Let's give them a bit more time,” the team eventually notices. Sometimes more time is justified. But repeated extensions without meaningful progress teach everyone that the standard is negotiable.

Be consistent across people

Nothing creates frustration faster than two standards. One employee is challenged for something. Another is allowed to do it because they have been there longer. Or because they are more difficult. Or because the manager likes them. Or because nobody wants the confrontation. People notice. Consistency matters.

Do not tolerate a high performer who damages everyone else either

The problem can work in reverse. Someone produces enormous commercial results. But behaves badly. The leader tolerates it because they are valuable. The good employees pay that cost too. High performance does not buy exemption from behavioural standards.

Ask what total contribution looks like

An employee's contribution includes more than their headline number. Think about: quality; reliability; behaviour; team impact; customer impact; follow-through; ownership; development. A person can hit one number while costing the organisation elsewhere.

Managers must model the standard

If leaders miss commitments without consequence, nobody takes accountability language seriously. If managers tolerate in themselves what they challenge in employees, resentment grows. The standard applies upwards too.

Use one-on-ones to surface frustration

A good one-on-one can reveal this before it becomes a resignation. Ask:

“What's frustrating you at the moment?”

Then listen. Perhaps the issue is workload. A colleague. A broken process. Do not automatically accept every complaint as fact. But investigate. Evidence again.

Do not promise what you cannot disclose

If an employee raises a colleague's poor performance, avoid saying:

“I'll sort them out.”

Instead:

“Thank you for raising it. I'll look at what is happening and deal with anything that needs addressing.”

Then follow through appropriately.
