Underperformance in the workplace costs your business more than you realise.
It isn’t just about one employee missing a target. The ripple effect can be significant: deadlines are missed, customer service slips, projects stall, team morale drops, and managers spend valuable time fixing issues instead of driving growth.
As an SME owner, you can’t afford to let underperformance slide. Acting early, identifying the root causes, and putting the right systems in place will protect productivity, strengthen your culture, and improve retention.
At HR Results Ltd, we specialise in helping small and medium businesses manage underperformance effectively, in line with UK employment law. Here’s our expert advice.
What does underperformance look like?
Underperformance isn’t always obvious. Yes, missed deadlines or customer complaints are clear warning signs, but often the decline starts more subtly.
Look for early signs such as:
🟢 A previously engaged employee becoming withdrawn or quiet in meetings.
🟢 Small but frequent errors creeping into reliable work.
🟢 Slower response times to requests or tasks.
🟢 Hesitation or reluctance to take on new responsibilities.
🟢 Tension or conflict with colleagues.
You can back up your observations with simple data:
🟢 Are they completing tasks on time and to the required standard?
🟢 Have sickness absences or lateness increased?
🟢 What feedback is coming from clients or customers?
🟢 How do their results compare with agreed objectives?
Regular one-to-ones are essential. They allow you to spot changes in engagement or capability before they escalate into serious performance problems.
Why employee performance drops
Poor performance rarely stems from laziness or lack of effort. More often, the root cause lies elsewhere.
Common causes include:
➡️ Role confusion – unclear responsibilities or job creep.
➡️ Inefficient systems – processes, tools, or resources not fit for purpose.
➡️ Skills gaps – roles evolve but training doesn’t keep up.
➡️ Personal circumstances – health, family, or financial pressures.
➡️ Hiring mistakes – the wrong skills or cultural fit.
➡️ Weak culture – lack of accountability leading to lowered standards.
Understanding the root cause is essential to managing underperformance fairly and effectively. Jumping to discipline without diagnosis can create legal risks and damage employee morale.
Managing underperformance effectively
To handle underperformance properly, you need to balance clear expectations with the right support. Four areas are critical:
1. Clear Roles and Expectations - eEmployees must know exactly what’s expected of them.
Actions to take:
🟢 Update job descriptions so they reflect current reality.
🟢 Set measurable, achievable performance targets.
🟢 Share performance metrics openly and consistently.
🟢 Review internal systems before blaming individuals.
2. Training and Development - skills gaps are usually fixable — attitude problems are not.
Actions to take:
🟢 Identify specific skill gaps rather than applying generic training.
🟢 Use coaching and mentoring to build confidence and capability.
🟢 Encourage peer-to-peer learning for practical skills.
3. Right People, Right Roles - not everyone thrives in the role they’re in.
Actions to take:
🟢 Assess whether success is realistic with the right support.
🟢 Consider alternative roles better suited to their strengths.
🟢 Make decisive calls where necessary to protect the wider team.
🟢 Review recruitment processes to avoid repeat mistakes.
4. Culture and Accountability - performance management is as much about culture as it is about individuals.
Actions to take:
🟢 Set and enforce clear performance standards.
🟢 Normalise regular, constructive feedback.
🟢 Recognise and reward strong performance.
🟢 Ensure underperformance isn’t hidden by colleagues covering gaps.
Taking action
Managing underperformance in the workplace is not about blame - it’s about building a culture of accountability, clarity, and support. For SMEs, where every employee makes a big impact, the stakes are even higher.
When you handle underperformance correctly, you don’t just improve results for one employee - you strengthen your whole business.
