Investigation Outcome Letter Templates & Samples
Last updated 2026-07-30
The outcome letter carries more legal risk per sentence than the report does. It goes directly to a party, it is read closely and often shared, and it is the document most likely to be produced in a subsequent claim. A letter that states more than the findings support, or that discloses the respondent's disciplinary outcome to the complainant, creates exposure the report itself would not.
The recurring judgment is how much to tell each party. Tell the complainant too little and the process feels like a black box, which drives escalation; tell them too much about the respondent's consequences and you risk a defamation or privacy problem. The workable middle is to tell each party the outcome on the allegations, confirm that action has been taken where it has, and withhold the specifics of another employee's discipline.
Jurisdiction
Written primarily against US federal standards — EEOC guidance, NLRB decisions and Title VII case law — and against general investigative practice. State law, sector rules (public employers, education, regulated industries) and collective agreements impose additional requirements this page does not cover. Where a page borrows a concept from another jurisdiction it says so explicitly. Outside the US, treat the structure as transferable and the legal references as not.

When to use this document
- At the close of every formal investigation, to both parties.
- Where an investigation is discontinued before findings, with the reason.
Worked example
Fictional scenario, continuing the dispatch-team matter. The two letters side by side on the same findings — the pair is the lesson, because the difference between them is the entire judgement this document exists to make.
Complainant version
Dear Ms Okafor,
I am writing to confirm that the investigation into your complaint of 29 May 2026 has concluded. It was conducted by R. Hall between 2 June and 14 July 2026.
Three allegations were investigated. The findings are:
1. That comments were made about your appearance on repeated occasions between February and May 2026 — SUBSTANTIATED.
2. That comments continued after you asked for them to stop — SUBSTANTIATED.
3. That you were physically prevented from passing in the corridor in April 2026 — INCONCLUSIVE.
On the third allegation, 'inconclusive' means the available evidence did not allow the investigator to determine what happened either way. It is not a finding that the incident did not occur, and it is not a finding that you were untruthful. The corridor is not covered by working CCTV and there was no other witness.
Where allegations were substantiated, the company has taken appropriate action. I am not able to share the details of that action, because it concerns another employee's confidential information.
Retaliation for having made this complaint is prohibited. If you experience anything you believe may be retaliation, contact me directly on the number below — not your line management.
You may request a review of this outcome within 10 working days.
Yours sincerely,
Director of Human Resources
Respondent version — same findings, different letter
Dear Mr Whelan,
I am writing to confirm that the investigation into the complaint of 29 May 2026 has concluded. It was conducted by R. Hall between 2 June and 14 July 2026.
The findings are:
1. That you made comments about a colleague's appearance on repeated occasions between February and May 2026 — SUBSTANTIATED.
2. That those comments continued after she asked you to stop — SUBSTANTIATED.
3. That you physically prevented her from passing in a corridor in April 2026 — INCONCLUSIVE. No finding has been made against you on this allegation.
On the facts found, the investigator concluded that section 4.1 of the Respectful Workplace Policy was breached.
This letter concludes the investigation. It is not a disciplinary decision. A separate disciplinary process will now be convened, at which you will be given the findings in full, an opportunity to respond on the question of sanction, and the right to be accompanied.
You are reminded that any contact with the complainant or with witnesses about this matter, or any detriment to them, would be treated as a serious separate matter in its own right.
You may request a review of these findings within 10 working days.
Yours sincerely,
Director of Human Resources
What differs, and why
The findings are identical and stated in the same words. Four things differ:
The complainant is told action was taken but not what it was — that is another employee's confidential information, and stating it is the most common route to a privacy or defamation problem in this document.
The respondent is told that the outcome letter is not the disciplinary decision. Merging the two removes his opportunity to be heard on sanction.
The inconclusive finding is explained to the complainant (so it is not read as disbelief) and stated protectively to the respondent (so it is not read as a finding against him). Same outcome, two readers, two risks.
The non-retaliation paragraph is a route to help in one letter and an instruction in the other.
Section-by-section guide
What each section is for, what a good one contains, and where they typically go wrong.
1.Letter header and recipient
Two versions of this letter exist. Prepare them separately and check which one you are sending — sending the respondent's version to the complainant is a live and recurrent error.
2.Confirmation the investigation is complete
That it has concluded, who conducted it, and the period it covered.
3.Outcome on each allegation
State the outcome for each numbered allegation using the same wording as the report. Where an allegation was inconclusive, say so and explain briefly what that means — parties routinely read 'inconclusive' as 'disbelieved', and a sentence of explanation prevents that.
4.What happens next (complainant version)
Confirm that appropriate action has been or will be taken where allegations were substantiated — without specifying another employee's discipline. Confirm the non-retaliation position and how to report any retaliation.
5.What happens next (respondent version)
The findings, what follows procedurally, and any separate disciplinary process with its own rights. Keep the investigation outcome and the disciplinary decision clearly distinct — they are separate processes and merging them removes a step the respondent is entitled to.
6.Appeal or review rights
What review is available, to whom, in what timeframe, and how to invoke it.
7.Support and closing
Support available and a named contact.
Common mistakes
The failure modes that show up most often when this document is reviewed later.
Telling the complainant what discipline the respondent received
It is another employee's confidential information and creates privacy and defamation exposure. Confirm that action was taken, not what it was.
Stating conclusions the report does not support
The letter is read far more often than the report. Any gap between them will be found and used.
Letting 'inconclusive' stand unexplained
Parties read it as disbelief. One sentence distinguishing 'the evidence did not permit a determination' from 'we did not believe you' prevents a large amount of escalation.
Merging the outcome letter with a disciplinary decision
They are separate processes with separate rights. Merging them removes the respondent's opportunity to be heard on sanction.
Questions
- The complainant is asking for the full report. Do we provide it?
- Usually not in full, because it contains third-party witness accounts that are not the complainant's to receive. Most organisations provide the findings rather than the report. Whatever your approach, apply it consistently to both parties and set the expectation at the acknowledgment stage rather than at the end, when refusing looks like concealment.
- How much detail should the complainant be told about the outcome?
- The outcome on each allegation they raised, and confirmation that appropriate action has been taken where allegations were substantiated. Not the specifics of another employee's discipline, which is that employee's confidential information.
- Should the parties receive a copy of the investigation report?
- Practice varies with policy and jurisdiction. Many organizations provide the findings rather than the full report, because the report contains third-party witness accounts. Whatever the approach, apply it consistently and set the expectation at the acknowledgment stage.
- What do we write when the investigation was inconclusive?
- State the outcome plainly, explain that it means the available evidence did not permit a determination either way, and confirm it is not a finding that the complainant was untruthful. Then set out any steps being taken regardless, such as refreshed training or ongoing monitoring.
