How to Manage Poor Performance

Practical Solutions That Improve Performance, Accountability and Workforce Effectiveness

Poorly managed performance is a common and costly challenge facing every organisation.

Managing Performance
In Short

Most poor performance is fixable, and most of it is fixable informally. Organisations that handle it well set clear expectations early, deal with problems in weeks rather than months, keep a simple written record, and separate “can’t do” from “won’t do” before deciding next steps. Formal capability procedures should be the last step, not the first.


Common Signs Your Organisation May Have a Performance Management Problem

Many organisations tolerate underperformance for longer than they should. Often it’s because managers lack the confidence or tools to address it effectively.

Persistent underperformance that is not being addressed
Managers avoiding or delaying difficult performance conversations
Inconsistent standards and expectations across teams
Appraisal processes that feel like a tick-box exercise
Increasing employee conflict, frustration or disengagement
High-performing employees becoming frustrated by poor levels of accountability
Rising absence levels or conduct concerns
Less clarity around roles, responsibilities or expectations
Lack of structured feedback, coaching or development conversations
Performance issues escalating into formal HR procedures which could have been prevented

What Causes Ineffective Performance Management?

Organisations typically struggle to manage performance effectively due to a combination of poor leadership / management, cultural and structural factors. Issues include:

Limited Management Capability and Confidence

Many managers are promoted for technical expertise rather than their people management skills.

Unclear Expectations and Accountability

When roles, responsibilities and performance standards are not clearly defined, employees may not fully understand what is expected of them.

Inconsistent Feedback and Coaching

Employees need regular, honest feedback to understand how they are performing and where they need to develop.

Outdated or Ineffective Appraisal Processes

Annual appraisal cycles that are compliance orientated rather than development focused rarely help improve performance for the long term.

Avoidance of Difficult Conversations

Many managers avoid addressing underperformance because they are scared to tackle it head on.

Workplace Culture

Cultures where low accountability is tolerated, where standards are applied inconsistently, or where feedback typically is seen as negative rather than constructive or developmental, can significantly undermine the effectiveness of performance management.

Insufficient Development and Support

Employees who lack access to development opportunities, coaching or other adequate support may struggle to perform at the level required, even where motivation and intent is high.


Managing Poor Performance Step by Step

A practical sequence that keeps most issues informal, fair and quick to resolve.

  1. Be Specific About the Performance Gap

    Write down what the person is expected to deliver, what they are actually delivering, and the evidence for the difference. If you cannot describe the performance gap in two or three plain sentences, you may not be ready to raise it.

  2. Work Out Why

    Performance problems usually have one of four causes: the person does not know what is expected, does not know how to do it, cannot do it because of something outside their control, or does not want to do it. Each requires a different response, and the wrong diagnosis is a common reason improvement plans fail.

  3. Have an Informal Conversation First

    A private, early, one-to-one conversation can normally resolve the majority of performance issues. Describe the performance gap, ask for the person’s view, agree what changes are needed and by when, and note it in an email afterwards. Do not skip this step to get to a formal process faster.

  4. Agree a Short Improvement Period and Provide Support

    Set two or three clear, measurable objectives over four to eight weeks, and be explicit about the support you will provide: training, coaching, a mentor, clearer priorities or more regular check-ins. Schedule review meetings in the diary.

  5. Review With Honesty

    At the end of the period, compare performance against the objectives you set, not against a general impression. If the person has improved, say so and close the matter. If they have partly improved, extend once with revised objectives, targets and a new timeline. If nothing has changed, move to a more formal performance management process.

  6. Follow Your Capability Procedure

    A fair formal process should include written notice of the concerns, a meeting where the person can respond, the right to be accompanied, a written outcome, further improvement periods with warnings, and the right of appeal. The ACAS Code of Practice on disciplinary and grievance procedures applies, and a tribunal can increase compensation by up to 25 per cent if it is not followed.

  7. Only Then Consider Dismissal

    Dismissal for capability is a potentially fair reason under the Employment Rights Act 1996, but only after a fair process and a genuine opportunity to improve have taken place. Before any final decision, consider whether an alternative role, adjusted duties or a further period would be reasonable in the circumstances. Take HR or legal advice at this point if you have not already.


Ten Practical Tips for Managing Poor Performance

Act in Weeks, Not Months

The longer a problem is tolerated, the harder it becomes to raise, and the more the person can reasonably say, “nobody told me”.

Describe Behaviour and Results, Not Personality

“The last three reports were late and two contained errors that clients noticed” can be discussed and fixed. “You are not committed enough” cannot.

Check the Whole Team Knows What Good Looks Like

If standards have never been written down or discussed, the problem may be the standard rather than the person. Also check whether standards are applied consistently across the team or organisation.

Ask Before You Tell

Open the conversation with a question about how the person thinks things are going. You will often learn something that changes your view, and the person is more likely to own the solution if their view is sought first.

Look for What Changed

Someone who performed well for years and has dipped recently almost always has a reason behind it. Workload, a new manager, a change in role or something outside work are all worth asking about before assuming a capability issue.

Distinguish Capability From Conduct

A person who cannot meet the standard despite trying may need support and a capability process. A person who has the capability but chooses not to use it is a conduct matter. Mixing the two can undermine both.

Keep Simple, Up-to-Date Records

A short email after each conversation, sent to the person, is worth more than a detailed note written from memory three months later.

Make the Support Real

An improvement plan that promises coaching support that never happens is unfair to the individual and will not survive scrutiny.

Do Not Let the Process Replace the Conversation

Forms and templates are there to record what was discussed. Managers who complete a form without having the honest conversation may struggle to improve performance.

Prepare the Manager, Not Just the Paperwork

Many managers have never been shown how to conduct a performance conversation. An hour of preparation or a practice run-through with HR can make a measurable difference to how the meeting goes, now and in future.


When to Handle It Yourself and When to Bring In Support

Handle It Yourself

Most performance issues should be handled by the line manager, and handling them effectively is a core management skill, not an HR task. The informal conversation, the improvement plan and the review meetings are yours to manage.

Bring In HR Support When

  • The manager has never run a capability process before, or the matter is likely to become formal
  • The individual has raised a grievance or a health issue, or the matter relates to a protected characteristic
  • The person is senior, long-serving or in a role that is hard to replace
  • Several managers are handling similar issues differently and you need a consistent framework
  • You are considering dismissal

In each of these situations, an hour of HR advice at the right time can save time and problems further down the line.

Common Mistakes We See

!

Jumping to the Formal Process

Going straight to a capability hearing because the manager finds the informal conversation uncomfortable. It can signal a lack of management skills, damage the working relationship and make improvement more challenging.

!

Improvement Plans With No Measurable Objectives

“Improve communication with the team” cannot be assessed at the review meeting. “Send the weekly update to the team by Friday midday each week for six weeks” can.

!

Inconsistency Across Managers

One team tolerates what another would escalate. When this is raised in a grievance meeting or at a tribunal, it can be hard to defend.

!

Raising a Long List of Historic Issues in One Meeting

If something mattered, it should have been raised at the time. A backlog of complaints suggests the manager has been avoiding the issue, and it can overwhelm the person rather than focusing on a practical fix.

!

Treating Every Dip as a Straightforward Capability Matter

A performance issue that started after a return from absence, a change of manager or a flexible working request needs care and usually professional advice, because other factors such as employment rights may be in play.

!

Ignoring the Effect on Everyone Else

Colleagues notice when poor performance goes unaddressed. Unresolved performance problems are one of the more common reasons good employees give for leaving.

Frequently Asked Questions

What is performance management?

Performance management is the ongoing process of setting clear expectations, providing regular feedback, supporting development and addressing performance concerns constructively. Effective performance management helps organisations get the best from their people by creating the clarity, accountability and development support that consistent high performance requires.

How can organisations improve performance management?

Improving performance management usually requires stronger management capability, clearer expectations, more consistent feedback, better-designed review processes and a culture where accountability and development are both valued. The essential starting point is an honest diagnosis of the specific causes of underperformance rather than the assumption that a new appraisal form or HR policy will address what are almost always more human or culturally based challenges.

Can psychometric assessments support performance management?

Yes. Behavioural and psychometric assessments can be used to help improve self-awareness, communication, development planning and management effectiveness. All of which support stronger performance management by helping individuals and managers understand how they work, what drives their behaviour and where the most important development opportunities lie.

Is poor performance always a capability issue?

Not always. Poor performance can relate to capability, motivation, clarity of expectations, management support, personal circumstances or organisational factors. Understanding the real cause is essential before deciding on the most appropriate response. The most effective intervention for a capability gap can be very different from the most effective intervention for a motivational or situational one.

Improve Performance. Build a Culture of Accountability.

Whether you are facing persistent underperformance, inconsistent management standards, outdated appraisal processes or a need to strengthen leadership capability, White Cube Consulting can help you identify practical solutions that improve performance and organisational effectiveness.
