The single most common thing managers do badly is not what most people expect. It is not giving too much feedback, or being too demanding, or setting unrealistic expectations. It is avoiding the conversation about underperformance until the situation has deteriorated so far that a supportive development conversation is no longer possible and a formal process is the only remaining option. By that point, the underperforming employee has often been confused, demoralised, and increasingly disengaged for months, while colleagues who are performing well have watched the underperformance go unaddressed and concluded, correctly, that standards are not consistently enforced.
Managing underperformance well is one of the most important and most avoided management skills. This guide covers how to identify underperformance early, how to structure the initial conversation in a way that is honest and fair without being aggressive, how to build a Performance Improvement Plan that genuinely supports improvement, and how to manage the process through to a clear outcome without the legal, emotional, and team damage that poorly handled underperformance processes consistently produce.
Key Takeaways
|
Early Intervention is the single most important principle in underperformance management. A performance concern raised at week four is a development conversation. The same concern raised at month twelve is a formal process. The earlier the conversation, the more options everyone has. |
Cause Before response. Underperformance has causes: skill gaps, motivation issues, personal circumstances, unclear expectations, poor management, role mismatch. The right management response depends on which cause is primary. |
Specific Behavioural evidence. Effective performance conversations are built on specific examples of what the person did or did not do, not on general characterisations of their attitude or effort. “I noticed X on these three occasions” not “you always…” |
PIP Performance Improvement Plans work when they are genuine development tools with clear standards, real support, and honest review. They fail when they are documentation exercises designed to justify a decision already made. Both employee and manager must believe improvement is genuinely possible. |
- Underperformance is any sustained failure to meet the performance standard expected for the role, whether in the quality of output, the quantity of work, the behaviours demonstrated, or some combination of these.
- Before any underperformance management process begins, the manager must be able to answer three questions clearly: what specifically is the person not doing that they should be doing (or doing that they should not be doing)? Has the expected standard been clearly communicated? And has the person been given a genuine opportunity to meet it?
- The causes of underperformance are different and require different management responses: skill gaps require development; motivation issues require investigation and coaching; personal circumstances require support and adjustment; unclear expectations require clarification; and genuine role mismatch may require a different conversation entirely.
- Formal performance management processes (PIPs, disciplinary procedures) are the right tool when informal management has failed or when the performance gap is serious enough to warrant immediate formal action. Using them as the first response to underperformance, before informal support has been genuinely attempted, creates legal risk and destroys any remaining possibility of improvement.
Why Managers Avoid the Conversation and Why That Makes It Worse
The avoidance of underperformance conversations is one of the most consistent management behaviours across organisations, sectors, and cultures. The reasons are understandable: the conversation is uncomfortable, the outcome is uncertain, the manager may genuinely like the underperforming employee, they may be unsure of the legal implications, and they may have had previous conversations that went badly and left them reluctant to have another. All of these reasons are comprehensible. None of them justify avoidance.
When underperformance is not addressed promptly, several things happen simultaneously. The underperforming employee receives no signal that their performance is below standard, continues working as they are, and often becomes more entrenched in the behaviours or approaches that are creating the problem. Colleagues who are performing well observe that the underperformance is going unaddressed and draw the correct conclusion that the manager will not enforce standards, which creates resentment, disengagement, and in some cases their own performance drift. And the eventual conversation, when it can no longer be avoided, is significantly harder, more emotionally loaded, and more legally complex than it would have been at week four.
The most effective reframe for managers who avoid these conversations is this: addressing underperformance early is an act of respect and support, not an act of aggression. Telling someone honestly and specifically that their performance is not meeting the standard, and working with them to understand why and how to improve, gives them the information and the opportunity that they need and deserve. Waiting until the situation is critical before saying anything denies them that opportunity.
Our article on how to deliver feedback constructively covers the structure and approach for exactly these conversations, framing them as developmental rather than punitive and building the skills that make managers more willing and more effective in delivering difficult feedback.
🎯 Build the management skills to handle performance conversations with confidence
The Performance Appraisal Training Course for Managers develops the performance standard-setting, evidence-based feedback, performance improvement planning, and difficult conversation skills that managers need to address underperformance fairly, consistently, and effectively.
Step 1: Identify the Cause Before Designing the Response
Underperformance is not a single problem with a single solution. It has causes, and the causes determine the appropriate management response. A manager who treats all underperformance as a motivation issue and responds with pressure will make skill-gap underperformance worse. A manager who treats all underperformance as a skill issue and responds with training will fail to address motivation-driven underperformance. Getting the diagnosis right before designing the response is the most important step in the whole process.
| Cause Category | Signs and Signals | Appropriate Management Response |
|---|---|---|
| Skill or knowledge gap | Person is trying but the output quality is consistently below standard; errors occur in the same types of task; person may acknowledge struggling | Clarify the gap; identify specific development need; structured training, coaching, or mentoring; adjusted timeline with clear milestones |
| Unclear expectations | Performance was acceptable previously; gap emerged after a role change, new manager, or significant change in work scope; person may be surprised by the feedback | Acknowledge the clarity issue if it exists; set explicit, documented standards; regular check-ins to verify understanding |
| Motivation or engagement | Person has demonstrated they can perform at the required level in the past; effort has reduced; disengagement signals; possibly looking for a new role | Coaching conversation to understand what has changed; explore whether role, manager, or organisational factors are driving disengagement; be honest about the performance concern simultaneously |
| Personal circumstances | Sudden or recent performance change; may be visible changes in behaviour or demeanour; the person may or may not have disclosed a personal issue | Supportive initial conversation; acknowledge the performance without making assumptions about cause; offer EAP or other support; agree reasonable adjustments and a review timeline |
| Role mismatch | Performance consistently below standard despite genuine effort and support; skills and working style fundamentally misaligned with role requirements; no clear development path to close the gap | Honest conversation about fit; explore alternative roles where person could succeed; formal process if no suitable alternative exists and gap cannot be closed |
The Initial Underperformance Conversation
The first formal conversation about underperformance (as distinct from brief, ongoing feedback) should follow a clear structure that is fair to the employee, specific enough to be actionable, and honest enough to give them a genuine picture of the situation. A useful structure is: Share the specific concern (what I have observed, with examples) then Explore (what is going on from their perspective) then Agree (what needs to change, what support is available, and how progress will be reviewed).
The evidence must be specific. “Your work has not been up to standard recently” is not feedback; it is a characterisation. “In the three reports submitted in April, the data sources were not cited, the executive summary did not match the body of the report, and two of the three recommendations were not supported by the analysis, which is the standard required for this level” is feedback. Specific, observable, evidenced. The specificity is what makes it fair to the employee and credible to the manager.
The exploration component is as important as the evidence. Giving the employee a genuine opportunity to explain their perspective, and listening to that perspective with an open mind rather than a predetermined conclusion, serves two purposes: it may reveal information that changes the picture (a personal circumstance the manager was unaware of, a systemic barrier to performance that the manager can address), and it gives the employee a voice in a process that directly affects them, which is both fair and legally important.
Our article on the manager as a coach covers the questioning and listening skills that make the exploration part of this conversation genuinely effective rather than a formulaic step before the manager delivers a predetermined conclusion.
Building an Effective Performance Improvement Plan
A Performance Improvement Plan (PIP) is the formal tool for managing underperformance that has not been resolved through informal management. It documents what specific improvements are required, what the standard of performance looks like, what support will be provided, the timeline for review, and the consequences of continued underperformance. It provides clarity for the employee, a documented basis for decision-making for the organisation, and, crucially, a genuine structure for improvement.
PIPs fail most commonly for one of three reasons. First, the performance standard in the plan is vague: “improve communication” or “be more proactive” are not measurable standards and cannot be fairly assessed. Second, the support provided is nominal: training that does not address the actual gap, or coaching that occurs once and then stops. Third, the plan is not genuinely intended to support improvement; it is documentation designed to justify a decision already made to exit the employee. Employees usually sense this, which ensures the plan fails regardless of how it is structured.
An effective PIP has: specific, measurable performance standards (what does “meeting the standard” look like for each area of concern?), a realistic timeline (typically four to twelve weeks depending on the severity and type of underperformance), specific support actions with named owners and dates, clear review milestones with documented assessment at each, and explicit statement of outcomes (what happens if the standard is met, and what happens if it is not).
🤝 Build the coaching skills that make underperformance conversations developmental
The Coaching and Mentoring Skills Training Course develops the questioning, listening, and structured conversation skills that managers need to turn underperformance conversations from confrontational events into genuine development discussions that give employees the insight and support they need to improve.
When Informal Management Escalates to Formal Process
Not every underperformance situation resolves through informal management and a PIP. When the performance gap is severe, when it involves serious conduct issues, or when genuine support has been provided without improvement, a formal process becomes necessary. The transition from informal to formal management should be handled carefully: the employee should understand clearly that the situation has escalated and why, the formal process should follow the organisation’s documented procedure consistently, and HR should be involved from this point to ensure procedural fairness.
The legal dimension of formal performance management varies by jurisdiction and employment contract terms, but several principles are consistent: the employee must understand what standard is required, they must have been given a genuine opportunity to meet it with appropriate support, and the process must be applied consistently (the same standard must apply to all employees in similar situations, not selectively to particular individuals). These principles protect both the employee’s rights and the organisation’s legal position.
The documentation discipline that formal process requires is covered in our article on how to foster accountability in teams, which addresses the ownership and follow-through practices that create the paper trail that fair formal processes depend on, not as surveillance but as evidence that expectations were clear and consistently applied.
The Team Dimension: Why How You Handle It Matters as Much as What You Decide
How a manager handles underperformance is observed by the whole team, even when the individual conversations are private. Team members will not know the specifics, but they will notice whether underperformance is addressed or tolerated, whether the manager is consistent, and whether the person who is underperforming is treated with dignity regardless of the outcome. All of these observations shape the team’s view of the manager and the culture’s view of what standards actually mean.
The most damaging pattern is not addressing underperformance harshly or compassionately. It is addressing it inconsistently, or not addressing it at all. High performers who observe persistent underperformance going unaddressed typically draw one of two conclusions: either the manager is unaware (which reduces their confidence in the manager’s judgement) or the manager is aware and has chosen not to act (which reduces their respect for the manager’s standards and their motivation to maintain their own high performance).
Conclusion: Address It Early, Honestly, and Specifically
Managing underperformance is one of the most important management skills and one of the least developed. Most managers receive no explicit training in how to have these conversations, how to structure a Performance Improvement Plan, or how to distinguish between a development need and a conduct issue. They learn by trial and error, which usually means learning late and expensively.
The managers who handle underperformance most effectively share three habits: they address it early, before avoidance becomes the default; they ground their feedback in specific, observable evidence rather than general characterisations; and they genuinely try to understand the cause before designing the response, because the cause determines whether the right intervention is development, coaching, role adjustment, or formal process. These habits are learnable. The organisations that invest in developing them in their managers consistently perform better, retain high performers longer, and build the accountability culture that high performance requires.
