Disciplinary and Performance Management
Managing employee behaviour and performance is one of the most sensitive aspects of employment law. At Thrive Law, we understand that employees may sometimes fall short of expected standards, and how an employer responds can significantly impact both the individual and the wider workplace.
A careful, fair, and legally compliant approach not only protects your business from potential claims but also preserves workplace morale and trust.
Why Effective Management Matters
Disciplinary and performance issues, if handled poorly, can escalate unnecessarily. Mistakes in process or communication can lead to:
- Unfair dismissal claims
- Discrimination or disability-related claims
- Reduced team morale and engagement
- Negative reputational impact
Conversely, addressing concerns thoughtfully and proactively can maintain a positive workplace culture, safeguard your business, and give employees a clear path to improvement.
How We Support Employers

- Step-by-step guidance: We help managers understand how to handle disciplinary or performance concerns sensitively and effectively. This includes coaching on communication, documentation, and decision-making.
- Investigation and hearings: As part of our Outsourced HR Support, we can provide a dedicated team member to conduct formal investigations or hearings, ensuring procedures are thorough and impartial.

Best Practice in Disciplinary and Performance Management
A fair and structured approach requires both legal compliance and human sensitivity:
- Early intervention: Address issues promptly before they escalate.
- Clear communication: Set expectations, provide feedback, and document conversations.
- Consistency: Apply policies fairly across all employees.
- Support and adjustments: Consider whether factors such as disability, health, or personal circumstances affect performance. Reasonable adjustments may prevent unfair treatment claims.
- Formal processes: If improvement does not occur, follow a structured disciplinary or performance management process, including warnings, improvement plans, and review meetings.
By combining legal expertise with practical guidance, employers can resolve issues proactively, reducing the risk of claims and maintaining a motivated workforce.
Common Pitfalls and Tips for Avoiding Employment Tribunal Claims
Even experienced employers can make mistakes in disciplinary or performance management. Awareness of these pitfalls and proactive planning can significantly reduce legal risk:
- Failing to Document Clearly
Pitfall: Decisions made without written records of meetings, warnings, or performance discussions.
Tip: Keep clear, contemporaneous notes. Document expectations, conversations, agreed actions, and timelines.
- Ignoring Early Warning Signs
Pitfall: Waiting too long to address performance or conduct issues.
Tip: Act promptly. Early intervention often resolves issues informally and prevents escalation.
- Inconsistency in Application
Pitfall: Treating employees differently for similar issues.
Tip: Apply policies consistently across the team.
- Neglecting Reasonable Adjustments
Pitfall: Overlooking potential disability, health, or personal factors affecting performance.
Tip: Assess whether reasonable adjustments are required under the Equality Act 2010.
- Failing to Follow Policy and Procedure
Pitfall: Skipping steps outlined in the employee handbook.
Tip: Ensure every stage – investigation, meetings, warnings, and reviews – follows the documented process.
- Poor Communication and Feedback
Pitfall: Providing vague or infrequent feedback, leaving employees unclear about expectations.
Tip: Deliver constructive, specific feedback and encourage dialogue.
- Overlooking Employee Engagement and Morale
Pitfall: Handling issues purely procedurally, without considering human impact.
Tip: Balance legal compliance with empathy to maintain motivation and trust.
By proactively avoiding these pitfalls, employers can manage disciplinary and performance matters fairly, reduce the risk of tribunal claims, and maintain a high-performing, engaged workforce.

FAQs
Disciplinary processes deal with conduct: behaviour that falls short of what’s expected, such as persistent lateness, misconduct, or a serious one-off incident.
Performance management deals with capability: where someone is not meeting the standard required for their role or is not able to perform that role to that standard.
The distinction matters because the processes are different. Performance management, done properly, involves setting clear targets, providing support, giving regular feedback, and allowing a reasonable opportunity for improvement before any decision is made. Running a conduct process when the real issue is performance, or vice versa, tends to go wrong and can give rise to unfair dismissal claims. Our disciplinary and performance management page covers both in detail.
The ACAS Code of Practice on Disciplinary and Grievance Procedures sets out the standard framework, and Tribunals take it seriously: a failure to follow the Code can result in an uplift of up to 25% on any compensation awarded. The core steps are:
- a proper investigation before any formal action is taken;
- written notification to the employee of the allegations and the potential outcome;
- a meeting at which the employee can respond (with the right to be accompanied);
- a decision that is reasonable and proportionate; and
- a right of appeal.
Procedural shortcuts are one of the most common reasons disciplinary decisions are challenged at Tribunal, even where the underlying conduct clearly warranted action. Document each stage carefully. Our team supports employers through disciplinary processes and can advise on managing complex or sensitive cases.
Yes, capability is one of the five potentially fair reasons for dismissal under the Employment Rights Act 1996. But the process matters enormously. A dismissal for poor performance will only be fair if the employer set clear and achievable standards, communicated those standards to the employee, provided appropriate support and time to improve, and warned the employee that dismissal was a possible outcome if performance didn’t meet the required level.
Under ERA 2025, the qualifying period for unfair dismissal is reducing to six months from January 2027. That changes the risk calculation for performance management during the early months of employment, and employers should be reviewing their probation processes and documentation now. Dismissal without a fair capability process, however frustrating the performance issue, remains a significant legal risk.
The right to be accompanied is the most significant: employees have a statutory right to be accompanied by a trade union representative or a fellow worker at any disciplinary hearing. That right can’t be waived by the employer. Beyond that, the employee is entitled to see the evidence against them in advance of the hearing (not the investigation), to respond to the allegations, and to put their case.
After the hearing, the employee must be given the outcome in writing, along with the right to appeal. Appeals should be heard by someone who wasn’t involved in the original decision, where possible. The appeal is not a formality: it should be a genuine reconsideration, and taking it seriously is important both as a matter of fairness and in managing Tribunal risk.
Before formal performance management begins, and throughout the process. If an employee is underperforming, the first question should always be whether there are any underlying health or personal factors that might be contributing. If there’s a disability involved (including mental health conditions and neurodivergent conditions), the employer has a legal duty to make reasonable adjustments, and that duty applies in performance management just as it does in any other employment context.
Failing to explore whether adjustments are needed before launching into a performance improvement plan is one of the more common errors we see. If it later emerges that the employee had a disability (which the employer knew or should have known of) which the employer failed to properly consider, the performance management process may give rise to discrimination claims as well as unfair dismissal. Taking a short pause to ask the right questions at the outset is almost always worthwhile. Our team can advise on managing performance where health or disability is a factor.
