[OBJECTIVE] You will be able to use AI to summarise investigation notes, draft hearing invitations, produce outcome letters, and maintain ACAS Code compliance throughout an ER case.
Every HRBP knows the feeling. A grievance investigation has produced 60 pages of interview notes, witness statements, and email chains. The hearing is in 48 hours. The hearing chair is a line manager who has never conducted a hearing before. And the outcome letter needs to be bulletproof — because one wrong word could become exhibit A at an Employment Tribunal.
LEGAL DISCLAIMER: Nothing in this course constitutes legal advice. All prompts and templates must be reviewed by a qualified employment law solicitor before use in live ER cases. Your organisation policies and legal counsel take precedence.
Using AI to Summarise Investigation Notes
The most immediately time-saving use of AI for grievance and disciplinary cases is turning a large volume of investigation material into a concise, structured fact summary that the hearing chair can actually use.
The key principle before you do anything: anonymise. Replace real names with role labels — Employee A, Manager B, Witness C. Remove specific dates if they are not relevant to the substance. Remove personal details that are not germane to the allegation. You are not losing information — you are protecting it.
PROMPT: Grievance Investigation Summary
Act as a senior UK HR Business Partner with expertise in employment law and ACAS compliance. I am going to provide you with summarised notes from a grievance investigation. Your task is to produce a structured Fact Summary for use by the hearing chair. Include: 1) The nature of the grievance as alleged, 2) Key factual findings with supporting evidence, 3) Any contradictions or inconsistencies, 4) Points that remain unresolved, 5) Relevant policies that apply. Keep the summary factual and neutral. Do not reach conclusions. Here are the anonymised investigation notes: [PASTE NOTES]
[TIP] Ask the AI to produce a second version formatted as a one-page briefing note for a line manager who has never chaired a hearing before. The AI will adjust the language and level of explanation automatically.
Drafting Hearing Invitations — ACAS Code Compliant
A disciplinary or grievance hearing invitation is not just an email. Under the ACAS Code of Practice on Disciplinary and Grievance Procedures, the invitation must meet specific requirements. Failure to comply with the Code can result in Employment Tribunal uplifts of up to 25 percent on any award.
The invitation must include: the nature of the allegation in sufficient detail, the date, time and location of the hearing, the right to be accompanied under Section 10 of the Employment Relations Act 1999, the potential outcome if the allegation is upheld, and information about how the employee can submit evidence or witnesses.
PROMPT: Disciplinary Hearing Invitation
Act as a UK Employment Law expert and HR professional. Draft a formal invitation to a disciplinary hearing that complies fully with the ACAS Code of Practice. Include: Employee role: [ROLE], Allegation: [DESCRIBE ALLEGATION], Hearing date/time/location: [DETAILS], Hearing chair: [NAME AND ROLE]. The letter must: confirm the right to be accompanied under Section 10 of the Employment Relations Act 1999, state the potential outcomes including [POTENTIAL SANCTION], confirm the employee may submit written evidence or request witnesses, provide a deadline for submitting additional evidence. Tone: formal, neutral, legally compliant.
[WARNING] Since April 2026, the ERA 2025 has strengthened employee protections. Ensure your disciplinary process documents are reviewed against your current policy and any updated ACAS guidance.
Drafting Outcome Letters
Outcome letters are where HRBPs spend disproportionate amounts of time — and where the stakes are highest. A poorly worded outcome letter can suggest predetermination, breach natural justice principles, or create inconsistency arguments in tribunal proceedings.
The outcome letter must: summarise the allegation and evidence considered, explain the findings of fact, give reasons for the decision, state the sanction and its rationale for proportionality, and explain the appeal process with timescales.
PROMPT: Disciplinary Outcome Letter — First Written Warning
Act as a UK HR Business Partner drafting a formal disciplinary outcome letter confirming a First Written Warning. Include: 1) A brief summary of the allegation, 2) A summary of the evidence considered, 3) The findings of fact, 4) The decision and reasoning including why a First Written Warning is proportionate, 5) The duration of the warning and what it means, 6) The improvement required, 7) The consequences of further misconduct, 8) The right of appeal including who to contact, the timeframe, and that the appeal must be in writing. Tone: formal, clear, legally defensible.
PROMPT: Grievance Outcome Letter — Partially Upheld
Act as a UK HR Business Partner. Draft a grievance outcome letter where the grievance has been partially upheld. The grievance related to [DESCRIBE GRIEVANCE]. Finding: [FINDING A] was upheld because [REASON], but [FINDING B] was not upheld because [REASON]. The letter must: acknowledge what the employee raised, explain which elements were upheld and which were not with clear reasoning, outline what action the organisation will take, and explain the right of appeal. Tone: professional, empathetic, clear.
Coaching Line Managers for Hearings
One of the most undervalued parts of an HRBP role is preparing line managers to chair hearings they have never chaired before. The manager is usually anxious, sometimes defensive, and frequently unclear on what they can and cannot say. AI can produce a manager briefing script in minutes.
PROMPT: Manager Hearing Briefing Script
Act as a senior UK HRBP coaching a line manager chairing a disciplinary hearing for the first time. The allegation is [DESCRIBE ALLEGATION]. Produce a step-by-step script covering: 1) Opening the hearing and confirming the purpose, 2) Presenting the management case and evidence, 3) Inviting the employee to respond, 4) Handling common responses including denial, mitigation, and counter-allegations, 5) Adjourning to consider the decision, 6) Reconvening to deliver the decision. Include specific phrases the manager should use and phrases they should absolutely avoid. Tone: practical, plain English, reassuring.
