Questions to Ask During a Workplace Investigation
Questions to ask during an investigation at work, for an HR investigator or a manager who has to look into a complaint of harassment, bullying or other misconduct and interview everyone involved. They follow the order an investigation usually runs: openers for every interview, then the person who complained, witnesses, the person accused, evidence and closing. Each has a note on what to listen for or what to do with the answer, and because the rules on companions, recording and confidentiality differ by country and employer, check how each works where you are; none of it is legal advice.

The questions
Each question, and why to ask it
Opening
Do you understand why I have asked to speak with you today?
Why ask it
Let them answer before you explain, because a guess shows how much of the story has already traveled around the office. Then say only what this person needs: that a concern was raised, that you are gathering facts, and that nothing has been decided.
What is your job here, who do you report to, and who do you work alongside most days?
Why ask it
Easy ground first, and it is not filler. Reporting lines show who holds power over whom, and the people someone works beside most days are the ones placed to have seen something. Check titles and dates against the HR record afterward instead of trusting memory.
Who have you already talked to about this, and what was said?
Why ask it
Two accounts that match word for word mean less if the two people compared notes over lunch. Write down names and rough dates, without scolding, and weigh later agreement between those people with that in mind.
Can you keep what we discuss to yourself while the investigation is open?
Why ask it
Give the reason with the request: each account should be that person's own. Avoid promising secrecy in return, since what they tell you may have to reach the other party and the decision-maker. How far an employer can require silence differs by place and policy, so settle the wording with your HR or legal lead first.
Has anyone pressured you about what to say, or treated you differently since this came up?
Why ask it
A worrying answer is concrete: shifts cut, a meeting invitation withdrawn, a manager stopping by to ask what they plan to tell you. Take the details and report them the same day to whoever your policy names, without waiting for the original complaint to be finished.
Do you know of any reason I should not be the one looking into this?
Why ask it
Put this to the person who complained and to the person accused. A friendship with either side, or a boss you share with one of them, is better heard now than in an appeal. If the objection is real, stop and hand the file to someone else before you go further.
Would you like someone with you in these meetings?
Why ask it
Know the answer to the follow-up before you ask. Who may bring a coworker, a union representative or a lawyer depends on the country, any union agreement and the employer's policy, so look it up for your workplace beforehand and offer the same thing to both sides.
I will be taking notes as we go. Is there anything you want to ask about how they will be used?
Why ask it
Say plainly who will read them, which your process should spell out, so the person is not left guessing. Wanting to record instead is a separate matter: consent to recording is handled differently from place to place and policy to policy, so get that answered before the meeting, not in it.
The complainant
Starting with the first thing that troubled you, what happened?
Why ask it
Then stop talking. The first telling, uninterrupted, shows what mattered most to them and in what order, and you can go back for dates and gaps afterward. Interrupting for detail early tends to produce short answers for the rest of the hour.
When and where did each incident take place?
Why ask it
Build a timeline together on paper. An approximate date anchored to something checkable, such as the week of the offsite or the day payroll ran, is perfectly usable. A date that moves each time you return to it deserves a gentle second pass, not a conclusion.
What exactly was said or done, in the actual words if you can?
Why ask it
'He was inappropriate' is a conclusion, and a finding needs the sentence, the gesture or the message behind it. Say out loud that you need the real words even if they are crude, and that repeating them will not be held against the person repeating them.
Who saw or heard it, and who did you tell soon afterward?
Why ask it
You are collecting two lists. The second is easy to skip, yet a coworker or relative who heard about it that same evening can tell you whether the account has stayed the same since. No witnesses at all is common for this kind of conduct and settles nothing by itself.
How did you respond in the moment?
Why ask it
Ask it as curiosity, never as a test. Laughing along, freezing and saying nothing are all ordinary reactions, so avoid any follow-up that begins 'why didn't you'. What they did next, such as leaving early or messaging a friend, may be something you can check.
Has it happened more than once, and has it changed over time?
Why ask it
One remark and a six-month pattern call for different interviews and different witness lists. For a pattern, get the first occasion, the most recent and the worst in detail, then ask roughly how often it happened in between.
Do you know of anyone else this has happened to?
Why ask it
Separate what they saw from what they heard secondhand, and take names for both. Do not promise that those people will be interviewed or that they will want to talk. If several names come up, tell whoever set your scope, since the investigation may need to widen.
Did you raise this with anyone before making the complaint, and what did they do?
Why ask it
An earlier report to a supervisor that went nowhere is a second matter to look into, and that supervisor is now a witness. Get the name, the approximate date and whether anything was put in writing.
Is there any history between you and this person that I am likely to hear about from someone else?
Why ask it
A past friendship, a relationship, a dispute over a promotion or a poor review belongs in your notes from them first. History does not cancel a complaint. It does tell you which dates to compare and which points the other side will raise.
How has this affected your work?
Why ask it
Listen for changes that leave a trace: swapped shifts, skipped meetings, a transfer request, sick days. Those can be compared with records. You are not there as a counselor, so if they are struggling, point them to whatever support the employer offers.
What do you need in order to work safely while this is open?
Why ask it
Common requests are a different schedule, a temporary change of reporting line or working from another site. Say you will take it to the person with authority to decide, and watch that any change does not land as a penalty on the one who spoke up.
What would you like to see happen as a result of this?
Why ask it
Some people want an apology, some a move, some only that it stops. Hearing it helps you understand the complaint, but make clear that the outcome is not theirs or yours to promise. It is also a poor guide to truth: wanting someone fired does not make an account false.
Witnesses
What did you see or hear yourself?
Why ask it
Mark each part of your notes as firsthand or passed along, because witnesses blend the two without noticing. 'Everyone knows what he is like' is worth one more question: what did you personally watch happen?
Where were you at the time, and what else was going on around you?
Why ask it
A witness two desks away on a call with headphones on saw less than they believe. Have them describe distance, noise and what they were doing, and consider visiting the spot if two accounts of what could be heard disagree.
What happened just before it, and what did each of them do right afterward?
Why ask it
A witness may have missed the remark itself and still have seen one person walk out or the other carry on with the meeting as if nothing had been said. Take what they watched happen and leave aside what they concluded from it.
How did the two of them get along before this?
Why ask it
Compare the answer with how each party described the relationship to you. A witness who says they ate lunch together until the spring has handed you a date to ask both of them about, and one who has rarely seen them in the same room can say little on the point.
Did you notice any change in either of them afterward?
Why ask it
Keep them to what could be observed: she stopped coming to the Friday meeting, he began sending everything by email. Their theory about why is less useful than the change and roughly when it started.
Has either of them talked to you about it, then or since?
Why ask it
Timing is the point. Something said the same afternoon carries different weight from something said after the complaint was filed, and a request to 'back me up' is worth writing down exactly as it was put.
What is your own relationship with each of them?
Why ask it
A close friend, a direct report or a rival for the same promotion can still be an accurate witness. You simply weigh the account knowing it. Someone who reports to the accused may also be afraid, so ask about that openly.
Have you seen this person act that way toward anyone else?
Why ask it
Hold it to occasions they witnessed, with a rough date and who was there. Disclose no more of the allegation than this witness needs in order to answer, or you will be the one spreading it.
How do people on your team usually talk and joke with one another?
Why ask it
It shows whether the conduct stood out or blended in. If the answer is that everyone talks like that, you have learned something about the team that belongs in your report, and it rarely settles the question about one person.
Is there anything you are holding back because you are worried about what happens next?
Why ask it
Say what the policy offers anyone who takes part, and do not promise anonymity you cannot deliver, since their account may reach the accused in some form. Ask how your process handles that before the interview so you can answer straight.
The accused
It has been reported that on [date] you [specific conduct]. What happened from your point of view?
Why ask it
Put each allegation separately and in plain terms, with enough detail that the person can answer it. A blanket 'none of it happened' to a blurred summary tells you little. Whether you may name the person who complained is a question for your policy and your HR or legal lead.
Which parts of that account are accurate, and which are not?
Why ask it
Most responses are neither a full denial nor a full admission. Go line by line and note what is agreed, what is disputed and what is 'I do not remember', then spend your remaining time on the disputed lines only.
What did you mean by it, and how do you think it came across?
Why ask it
For when the conduct is admitted and the meaning is disputed. Record both halves in their words. Many conduct policies look at the effect as well as the intent, so read yours before the interview and do not tell the person which one counts.
Do you supervise, schedule or evaluate [name] in any way?
Why ask it
Authority changes what the same remark means and what the other person could safely say back. Ask about informal power too: who assigns the good shifts, who is consulted on promotions, who signs off on time away.
Can you think of any reason someone would report this if it did not happen?
Why ask it
A specific answer, such as a denied request three weeks earlier, can be checked against dates and documents. 'That is just how she is' cannot. Ask it neutrally, and keep in mind that a motive and a true complaint can exist together.
Has a manager or coworker ever told you that something you said or did made them uncomfortable?
Why ask it
Broader than asking about formal complaints, which many people have never had. A yes gives you someone else to interview. A firm no that a manager's notes later contradict will affect how you weigh the rest of what they said.
I am showing you a message dated [date] that appears to come from your account. What can you tell me about it?
Why ask it
Hand over the document and let them read all of it before answering. Describing it from memory invites an argument about your summary. Ask whether they sent it, what came before it in the thread, and whether anything is missing.
Who can confirm your account, and what would each of them be able to tell me?
Why ask it
Follow up every name, or write down your reason for leaving one out. An investigation that heard only the complaint's witnesses is easy to attack. Being unable to name anybody does not sink their account, because private conversations have no audience.
Have you had any contact with [name] about this since you learned of the complaint?
Why ask it
'I only wanted to clear the air' is the answer to worry about. State plainly what you are asking of them from here on: no approaching the person, no asking colleagues who said what. Note that you said it and when.
Evidence
Do you have any texts, emails, chat messages, photos or voicemails connected to this?
Why ask it
Ask for the whole thread, not the one message that stands out, with the sender, date and time showing. A screenshot cropped to a single line is a reason to ask for what sits above and below it.
Did you write anything down at the time?
Why ask it
Diaries, a notes app, an email to themselves, a message to a friend that night. Find out when each record was made and label it, since something written within hours and a list compiled last week are both useful in different ways.
Is any of it on a personal phone or account, and are you willing to share it?
Why ask it
Request, do not demand, until you know the rules. What an employer may ask for from a personal device depends on local law and its own policies. Either way, ask the person to keep everything and delete nothing.
Has anything been deleted, edited or lost since this happened?
Why ask it
Put it plainly and without accusation, because disappearing-message settings and phone upgrades explain a good deal. If work systems are involved, speak to IT that day about what is retained and for how long.
Is there anything that would show who was where that day: a schedule, badge records, a calendar invitation, a camera?
Why ask it
Footage is often overwritten on a cycle, so ask facilities straight away how long theirs is kept. What you are allowed to view, cameras and private messages especially, depends on privacy rules where you are and on policy. Ask before you pull it.
Can you show me where it happened, or sketch it?
Why ask it
A quick drawing with each person marked on it exposes disagreements that words hide. Standing in the room settles small disputes quickly, such as whether the door has a window or whether a voice carries to the next desk.
Is there anything I am likely to find that needs explaining?
Why ask it
Friendly messages sent after an incident, a deleted post, a joke that reads badly out of context. Hearing the explanation before you find the item lets you weigh both together, and friendliness afterward does not by itself show that nothing happened.
Closing
What have I not asked you that I should have?
Why ask it
Count to five before you move on. This is the point where a second incident or a name nobody has given you tends to surface, and when it does it needs the same dates, words and witnesses you asked for the first time around.
Who have we not mentioned that I ought to speak to, and why them?
Why ask it
Put it to every interviewee and compare the lists. A name three people offer goes to the top of your schedule. Someone both sides leave out, though the roster puts them in the room, is worth a call as well.
Do you know who to tell if anyone treats you badly for taking part?
Why ask it
Give a name and a direct way to reach that person, and offer examples so they recognize it: a worse schedule, being frozen out, pointed comments. Promise what the employer's policy promises and no more. What the law adds on top differs by place, so get that from your HR or legal lead and not from memory.
If you remember something later, will you contact me directly instead of telling coworkers?
Why ask it
Details surface on the drive home. Hand over a phone number or address that only you read, and date anything that arrives afterward so the file shows when it was added.
Will you read my written summary of your account and confirm that it is accurate?
Why ask it
Send it within a day or two while memory is fresh. When a correction comes back, file it next to your first version so both can be read. Whether statements are signed, and who gets to read them later, is set by your process, so tell the person honestly who may see it.
What questions do you have about what happens next?
Why ask it
Describe the steps without dates you cannot keep: remaining interviews, a report, a decision by someone named. How much of the outcome each person will be told varies by employer and location, so check before the interview and do not promise more than that.
Running a fair workplace investigation
Practical guidance for the conversation itself
Before the first interview
Write the scope down
Put the allegations in a few plain sentences: who, what, roughly when, and which policy they fall under. Agree it with whoever commissioned the investigation. When a new allegation appears halfway through, go back to that person and ask whether the scope widens instead of deciding alone.
Check that you are the right person
An investigator who manages one party, is friends with the other or will also decide the outcome invites doubt about the result. If any of that applies, say so before you start. For a complaint about someone senior, ask whether a person from another team or an outside investigator should take it.
Secure the records first
Before anyone is interviewed, ask IT and facilities what exists and how long it is kept: email, chat logs, door records, camera footage, schedules. Some of it is overwritten on a short cycle. What you are permitted to look at depends on local privacy rules and the employer's policies, so ask before you open anything.
Decide the order of interviews
A common order is the person who complained, then witnesses, then the person accused, so that every allegation can be put to them in full. There are reasons to vary it, such as a risk that evidence will disappear. Whatever you choose, expect to go back to at least one person a second time.
Find out the local rules
Three things vary by country, state, union agreement and employer: who may bring a companion, whether interviews can be recorded, and how far you can require confidentiality. Get answers from your HR or legal lead before the first meeting. Guessing in the room is how a sound investigation gets undone.
Running each interview
Start open, then narrow
Begin each topic with a question the person can answer at length, and save who, when and where for afterward. Closed questions asked too early teach people to give short answers.
Keep your own words out of their account
'Did he shout at you?' puts shouting into the record whether it happened or not. 'What did his voice sound like?' does not. Read your notes afterward and check that the strong words in them came from the interviewee.
Ask everyone the same core questions
The opening, evidence and closing questions on this page go to every person, including the one accused. Treating people the same way is the simplest sign that the process was even-handed.
Write down words, not impressions
Note what was said, as near to verbatim as you can on the points that matter, with the date, the time and who was present. 'Seemed evasive' is your opinion. 'Paused, then said he could not recall the meeting' is a record.
Bring a second person if you can
One of you asks and the other writes. The note-taker can also speak to how the interview was conducted if the process is challenged later.
Tell witnesses only what they need
A witness can be asked about a meeting on a given day without hearing the whole allegation. The less you disclose, the less there is to repeat, and the more their account is their own.
Weighing accounts that conflict
Look for what can be checked
Start with the parts of each account that touch a record or a third person: a time, a message, who was on shift. An account that holds up wherever it can be tested earns more weight on the parts that cannot.
Compare each account with itself
Small differences between tellings are normal and can be a sign that nobody rehearsed. A change on a central point, or a detail that appears only after the person learns what others said, calls for a follow-up question.
Be careful with demeanor
Nervousness, anger, tears and calm all show up in people telling the truth and in people who are not. Note what you observed if you wish, and base the finding on something sturdier.
Ask which standard applies
Your finding answers whether the conduct happened, measured against the standard your policy sets. How sure you have to be, and who makes the final call, differ between employers and places, so confirm it before you write. 'Could not be substantiated' is a legitimate result and is different from 'did not happen'.
Keep findings apart from consequences
The report says what you found and why. What follows from it usually belongs to someone else. Mixing the two makes a report read as though the outcome was chosen first.
Protecting people while it is open and after
Interim arrangements
Two people can be kept apart during an investigation by schedule, seating, reporting line or time away from work. Who can authorize each, and what the accused is told, depends on the employer. Look again at any arrangement that puts the cost on the person who complained.
Check in on retaliation
Asking once at the interview is not enough. Go back to the person who complained and to key witnesses a few weeks in and again after the outcome, and ask what has changed in their schedule, their assignments or how people treat them.
Keep both sides informed
Silence breeds rumor. A short message that the investigation is still open and roughly what stage it has reached costs little, and it goes to the accused as well as to the person who complained.
Closing it out
Each party should hear that the investigation has ended. How much of the result, and of any action taken, can be shared with whom varies by employer and location, so ask before you speak to either of them.
The file
Keep notes, summaries, evidence and the report together, stored where only the people who need them can reach them. How long they have to be kept is another thing to ask your HR or legal lead.
