Quick checklist
Start with these
Identify The Investigation Stage
Start by explaining whether the issue is disciplinary, grievance, whistleblowing, discrimination, performance, misconduct or another workplace process. Identify whether you are the employee, employer, investigator, witness or another affected person.
Acas describes an investigation as the process used to find out the facts in a possible disciplinary or grievance issue. A useful enquiry should show what facts were investigated, what evidence was considered and what decision is now being contemplated.
- Terms of reference, allegation letter or grievance letter.
- Investigation plan, report, appendices and decision letter.
- Interview notes, witness statements and evidence relied on.
- Disciplinary, grievance, whistleblowing, equality or sickness policies.
- Suspension letter, meeting invites, appeal papers and current deadlines.
Organise Evidence Fairly
Separate documents that support the allegation from documents said to answer it. Mark missing documents, disputed notes, confidentiality concerns and any request for adjustments or companion arrangements.
If there is potential tribunal context, include Acas Early Conciliation dates, ET1 or ET3 papers, dismissal or resignation letters and the remedy or risk issue being considered.
Scope The Barrister Request
A barrister may be asked to advise on procedure, merits, disciplinary outcome risk, grievance response, appeal grounds, tribunal pleadings or hearing preparation. Be clear whether you need oral advice, written advice, drafting or representation.
Some matters need solicitor or HR support for ongoing correspondence, evidence gathering, privilege management, settlement negotiation or workplace implementation.
