Guidance for England, Scotland and Wales. Northern Ireland employment rules can differ.

Decide which process fits the concern

Understand whether the issue concerns conduct, capability, sickness or something else before beginning a formal disciplinary procedure. Some matters can be resolved informally; serious or unresolved concerns may require a formal process.

The Acas Code is the minimum framework for discipline and grievance cases. Acas is consulting on an updated Code, so use the current published Code and procedure rather than assuming a draft has replaced it.

Investigate and explain the allegations

Gather relevant evidence and establish the facts without deciding the outcome in advance. Keep the investigation proportionate and identify information that may support the employee's account as well as the allegation.

If a formal hearing is needed, explain the issue, possible consequences and relevant evidence with enough time to prepare. Check the right to be accompanied and any reasonable adjustments. Where practical, different people should investigate and make the disciplinary decision.

Hear the response and give a reasoned decision

Give the employee an opportunity to answer the allegations and discuss the evidence. Adjourn for further investigation where new information needs checking. Do not use a prewritten outcome as a substitute for considering the response.

Confirm the decision in writing, including the reasons and any required improvement, timescale or warning. Explain how to appeal. An appeal should be handled impartially, where possible by someone not previously involved.

In practice

An attendance score is a starting point, not a verdict

A manager sees a high absence score and suspects misconduct. Before taking disciplinary action, they check the underlying dates and reasons and discover that some absences relate to an agreed disability adjustment.

The next step is to correct the record and consider the appropriate support or process. A numerical threshold alone does not establish misconduct or justify a predetermined sanction.

Your next steps

  1. Identify the concern and choose the appropriate process.
  2. Gather evidence fairly and record the investigation.
  3. Give clear notice, preparation time and the applicable accompaniment rights.
  4. Consider the response, explain the outcome and provide an impartial appeal route.
