How to Conduct a Fair Disciplinary Process: A Step-by-Step Guide for UK Employers

One of the most significant, and least discussed, sources of Employment Tribunal liability for UK employers is the failure to follow a procedurally fair disciplinary process. This obligation affects all employers regardless of size and applies each time formal disciplinary action is taken. This article explains how the disciplinary framework operates in practice, what the ACAS Code of Practice requires of employers at each stage, and what the consequences are for businesses that fail to follow a fair procedure.

What This Means for UK Employers

Managing a disciplinary process is one of the most challenging tasks a manager can face. However, following a fair and transparent procedure is not just a matter of good management; it is a legal necessity. In the UK, failing to follow a fair process can lead to successful claims for unfair dismissal at an Employment Tribunal, even if the underlying reason for the disciplinary action was entirely valid.

The following steps align with the ACAS Code of Practice on Disciplinary and Grievance Procedures and should be followed in every case.

1. Conducting a Thorough and Impartial Investigation

The goal of an investigation is to establish the facts. It is not about proving guilt; it is about gathering all relevant evidence, both for and against the employee.

• Appoint a separate investigator: the person investigating should not be the person who will later conduct the disciplinary hearing, to avoid allegations of bias or pre-determined outcomes.
• Gather all relevant evidence: this includes emails, CCTV footage, documents, and witness statements.
• Hold an investigation meeting if necessary to obtain the employee's account. This is not a disciplinary hearing, and there is no statutory right to be accompanied at this stage, though company policy and individual circumstances should be considered.
• The investigator must determine whether there is a case to answer before the matter proceeds to a formal hearing.

2. Notifying the Employee of the Disciplinary Hearing

If the investigation establishes a case to answer, the employee must be notified in writing before any hearing takes place. The notification letter should include:

• The specific allegations being made.
• The potential consequences, including whether dismissal is a possible outcome.
• Copies of all evidence gathered during the investigation.
• The date, time, and location of the hearing.
• A reminder of the employee's right to be accompanied.

3. The Right to Be Accompanied at a Disciplinary Hearing

Employees have a statutory right to be accompanied at a formal disciplinary hearing. Failure to permit accompaniment is a breach of the statutory right and can result in a separate tribunal award.

• A companion must be one of the following: a fellow worker, a trade union representative, or an official employed by a trade union.
• Managers must be flexible if a companion cannot attend on the original date, and should permit a postponement of up to five working days.
• Postponements should not be allowed indefinitely; this right cannot be used as a tactical delaying mechanism.

4. Conducting the Disciplinary Hearing and Reaching a Decision

The hearing is the employee's opportunity to state their case. The process must be conducted fairly and with an open mind; a decision should never be made before the hearing is concluded.

• Open the hearing by setting out the allegations and presenting the evidence.
• Allow the employee to respond fully, ask questions, and present their own evidence or witnesses.
• Adjourn before reaching any decision to allow time for proper deliberation.
• When deciding on a sanction, apply the reasonableness test: is this outcome within the range of reasonable responses given the facts, the employee's record, any mitigating factors, and how comparable cases have been handled?

The outcome must be communicated in writing and must include the findings, the sanction imposed, the reasons for the decision, and the employee's right to appeal.

5. Managing the Appeals Process Fairly

A fair process must provide the employee with a genuine right of appeal. An appeal that is heard by the same manager who conducted the hearing, or that is treated as a formality, will undermine the fairness of the overall procedure.

• The appeal hearing should be conducted impartially and, wherever possible, by a manager who was not previously involved in the case.
• The final decision following the appeal must be communicated to the employee in writing.
• The appeal should consider whether the original decision was correct on the facts and whether the procedure was followed properly.

Why This Matters in Practice

• Unfair dismissal liability, procedural failures can render an otherwise valid dismissal unfair, even where the substantive reason was sound.
• Tribunal uplift, failure to follow the ACAS Code of Practice can result in a tribunal increasing any compensation award by up to 25 per cent.
• Accompaniment breach, denying an employee their statutory right to be accompanied is an independent breach attracting a separate award.
• Bias findings, using the same manager for investigation and hearing creates a risk of the process being found procedurally unfair.
• Appeal failures, conducting an appeal as a formality, rather than a genuine reconsideration, will be scrutinised and can undermine the overall fairness of the dismissal.

Why Work with a Specialist Employment Lawyer

Employment law is complex, and every disciplinary case presents unique risks that require tailored legal advice.

• Advise on whether the facts support a disciplinary process or whether an alternative procedure is more appropriate.
• Review investigation outcomes and hearing letters to ensure they are legally compliant and procedurally sound.
• Provide guidance on the appropriate sanction, including whether the facts support summary dismissal for gross misconduct.
• Assist with appeals and advise on litigation risk where a tribunal claim has been threatened or issued.

Following a Fair Disciplinary Process to Protect Your Business

Businesses should be aware of their obligations under the ACAS Code of Practice on Disciplinary and Grievance Procedures and begin ensuring their processes are compliant now. Ensuring you are ready to conduct a fair, documented, and procedurally sound disciplinary process is not optional, it is a legal obligation that applies to every employer in the UK.
