In My What actually happens in an HR investigation
Whether you raised a grievance or an allegation was made about you, the word "investigation" lands heavily. Knowing the shape of the process — what happens, in what order, and what your rights are at each stage — takes a lot of its power to frighten away.
The stages, in order
- 1. Commissioning. Someone (usually HR or a manager) is appointed to investigate. Good practice: the investigator is not the person the complaint is about, nor the complainant's close ally. An investigator with an obvious stake in the outcome is a procedural failing worth noting.
- 2. Scoping. The investigator defines what questions they're answering. You're entitled to know, at least broadly, what is being investigated — especially if it's about you.
- 3. Evidence gathering. Documents, emails, records — and interviews. Witnesses are usually interviewed separately and asked for their own recollections in their own words.
- 4. Your interview. If the matter concerns you, you'll be interviewed. In the UK, an investigation interview is not usually a formal disciplinary hearing — but if it might lead to one, prepare as if it matters, because it does. Notes will be taken; ask to see them and correct inaccuracies before signing anything.
- 5. The report. Findings of fact and (usually) a recommendation: no case, informal resolution, or a formal hearing. You will not always see the full report — but if an outcome affects you, you're entitled to enough of the evidence to answer it.
- 6. The outcome letter. Whatever the result, a fair outcome letter tells you what was found, what happens next, and how to appeal. Check the appeal information every time — its absence is itself a failing.
How long should it take?
The honest answer: "without unreasonable delay" (the ACAS standard) — which in practice means weeks, not days, and not months without explanation. Long silences are common and corrosive. A polite written check-in ("could you let me know the expected timescale?") is always legitimate, and the reply — or its absence — goes in your log.
Being a strong witness in your own case
- Bring documents, not adjectives. "On the 14th, this email" beats "constant undermining" every time. Let the pattern emerge from dated facts.
- Stay factual under provocation. Investigators weigh credibility; calm specificity is the most credible register there is.
- Never guess. "I don't recall — I can check my notes" is a strong answer, not a weak one.
- Take your companion. If the meeting is one where the right to be accompanied applies, use it — a second pair of ears matters more than the moral support, and the moral support matters.
- Afterwards, write it down — who asked what, what you said, anything that surprised you. Same-day notes are gold if the process later goes wrong.
What bad process looks like
Vague allegations you can't answer. Evidence you're never shown. An investigator with a stake in the outcome. Witnesses who were obviously coached or never interviewed. Outcomes that arrive pre-decided. Delays with no explanation. If you recognise several of these, document them precisely — procedural failings are not just unfair, they're leverage: in the UK, a tribunal can adjust compensation where an employer unreasonably ignored the ACAS Code, and an appeal built on specific process failures is far stronger than one built on disagreement with the outcome.
