Underperformance occurs when an employee consistently falls short of the standards expected in their role. This may involve missed deadlines, declining work quality, reduced productivity or behaviour that negatively affects colleagues and the wider team.
Performance issues should be addressed early. Left unresolved, they can damage morale, increase pressure on other employees and reduce overall business performance. However, underperformance does not always indicate a lack of ability or commitment. It may be caused by unclear expectations, insufficient training, excessive workload, poor management, health concerns or difficult personal circumstances.
A fair and constructive approach can help identify the cause, provide appropriate support and give the employee a genuine opportunity to improve.
Managers need to remain alert to meaningful changes in behaviour, attitude and output.
Common indicators include:
One isolated mistake does not necessarily indicate a wider performance issue. Managers should look for recurring patterns and assess the evidence objectively before drawing conclusions.
The first step is to recognise that an issue exists rather than hoping it will resolve itself.
Document specific examples of where performance has fallen below the expected standard. Focus on observable facts, such as missed deadlines, incomplete work or agreed procedures not being followed.
Avoid vague statements such as:
“Your attitude has been poor.”
Instead, explain the behaviour and its effect:
“The last three monthly reports were submitted after the agreed deadline, which delayed the finance team’s review.”
Where appropriate, involve HR to ensure the process follows company policy and that the employee is treated consistently and fairly.
Underperformance can sometimes result from unclear or changing expectations.
Review the employee’s:
Explain clearly what is expected, where the current performance falls short and what acceptable performance looks like.
This conversation should leave no uncertainty about the required standard.
Before deciding how to respond, give the employee an opportunity to explain their perspective.
Useful questions include:
Possible causes may include:
Understanding the cause helps ensure the response is proportionate and effective.
Once the issue has been discussed, agree a practical action plan.
The plan should include:
Specify exactly what needs to change.
Use clear measures such as deadlines, quality requirements, output or service levels.
Allow enough time for improvement while maintaining appropriate urgency.
This may include:
Schedule regular meetings to monitor progress.
Explain what may happen if the required improvement is not achieved, in line with company policy and employment law.
Involving the employee in the plan encourages ownership and makes the process feel supportive rather than imposed.
Performance improvement requires ongoing attention.
Regular check-ins allow the manager and employee to:
Avoid waiting until the end of the agreed period to raise further concerns. Feedback should be timely so the employee has a reasonable opportunity to respond.
When performance begins to improve, acknowledge it.
Specific praise is more effective than a general compliment. For example:
“The last two reports were completed accurately and on time, which helped the team meet its monthly deadline.”
Recognition reinforces the desired behaviour, builds confidence and demonstrates that the process is genuinely focused on improvement.
Delaying the conversation often allows the problem to become more serious and increases frustration within the team.
Do not decide that the employee is lazy, disengaged or incapable without first understanding the circumstances.
Unless the matter involves serious misconduct or a clear policy breach, the initial response should usually focus on clarification, support and improvement.
Employees cannot improve if they do not understand what needs to change.
Performance conversations should be held privately and handled confidentially.
Stress, burnout, disability or personal difficulties may be contributing factors. Managers should respond sensitively and involve HR or occupational health where appropriate.
It is unreasonable to demand improvement while withholding the training, tools or guidance needed to achieve it.
Despite appropriate support, some employees may not reach the required standard.
Where performance remains inadequate, the organisation may need to move to a formal capability or disciplinary process, depending on the circumstances and internal policy.
Any formal action should be:
The employee should understand the concerns, the support already provided and the possible outcomes.
Performance management is not only about responding when something goes wrong.
Managers can reduce the likelihood of underperformance by:
A supportive management culture makes employees more likely to raise difficulties before they become serious.
Underperformance does not have to become a purely negative experience.
Handled well, it can create an opportunity to clarify expectations, resolve underlying problems and support meaningful development. The most effective approach combines honesty, fairness, evidence and practical support.
By recognising the warning signs early, discussing concerns directly and agreeing a clear improvement plan, employers can help people return to strong performance while protecting productivity, morale and trust across the wider team.
