Questions and Recording Standards for Workplace Harassment Witness Interviews

The questions and recording standards for witness interviews regarding workplace harassment are items that investigators must organize to verify the facts. A witness interview is not a procedure to confirm the position of the complainant or the accused on their behalf, but rather a process of verifying the facts directly seen or heard by the witness and recording them in the investigation.

short answer

The witness interview for workplace harassment is A method of confirming facts directly experienced or perceived by a witness It is recommended to proceed in this manner. The investigator should avoid explaining the entire case to the witness, asking questions based on a specific conclusion, or requesting an evaluation of the complainant or the accused.

The information that can be verified during a witness interview primarily includes the date and time of the incident, the location, the situation at the time, statements or actions, people present, the context, subsequent changes, and any materials that can be submitted. Conversely, it is advisable to avoid questions that induce evaluation or speculation, such as “Who do you think is right?”, “Is the accused person inherently like that?”, or “Is the complainant overly sensitive?”

Records should be organized around the facts necessary for the purpose of the investigation, rather than transcribing everything the interviewer heard. In particular, access rights must be restricted to prevent the unnecessary sharing of the witness's identity, statement content, circumstances of the report, and information about other witnesses.

The key point is Information on the purpose of the interview → Information on confidentiality → Verification of directly perceived facts → Restriction on speculative or evaluative questions → Confirmation of the gist of the statement → Record storage and access control management → Additional verification if necessary It is to create a flow.

When will it be applied?

Standards for questions and records regarding witness interviews for workplace harassment are required in the following situations.

situation	Items to check by the person in charge
The statements of the complainant and the accused differ.	Confirming facts directly seen or heard by the witness
There were several people at the meeting and conversation at the time.	Check attendees, remarks, atmosphere, and context
There is data such as messenger messages, emails, and recordings.	Check if the reference person can explain the context of the material
Rumors are spreading within the department	Distinguishing between facts and speculation and confidentiality guidelines
The witness feels burdened by the interview.	Guide to Interview Purpose, Confidentiality, and Prevention of Disadvantage
The witness is in the same department as the party involved.	Concerns over retaliation and pressure confirmed due to leaked meeting schedule
Interviewed several witnesses in sequence	Prevention of statement contamination and management of interview order
Before writing the investigation results report	Summary of the facts and supporting evidence in witness statements
Follow-up management after the investigation is completed	Check if the witness suffered any disadvantage or burden of the relationship.

Witness interviews are a procedure designed to enhance the fairness of an investigation, but inappropriate interviewing methods can lead to secondary harm or the spread of rumors. Therefore, it is advisable to define the scope of questions and the recording method before the investigation begins.

What HR and Research Managers Should Do

1. We will first explain the purpose of the interview and the confidentiality standards.

Since the witness is neither the complainant nor the accused, they may feel burdened by why they are being interviewed. It is advisable to explain the purpose of the interview and the standards of confidentiality before starting the interview.

Example guidance text can be used as follows.

Today's meeting is a procedure to objectively verify the facts regarding the workplace harassment report. This is not an occasion to assign blame to the witness, but rather to confirm what was directly seen or heard. We kindly ask that you refrain from unnecessarily sharing the details of the meeting or information related to the investigation.

The items to be provided before the interview are as follows.

Guide Items	Explanation
Purpose of the interview	Interview with a witness to verify the facts
witness status	They are not the complainant or the accused, but are subjects of reference statements.
Question range	Verify based on facts directly seen or heard
Confidentiality	Instructions to avoid unnecessarily sharing interview facts and investigation details
Prevention of disadvantages	Manage to ensure no disadvantages arise for participating in the interview
Additional tips	If you remember anything after the interview, please convey it to the designated person in charge.
Record management	Interview records are retained to the extent necessary for the purpose of the investigation.

Explaining too much case information to a witness may reveal the direction of the investigation or influence their statement. It is advisable to guide them on the purpose of the interview only to the extent necessary.

2. Questions are structured around facts directly perceived.

It is better to ask witnesses “what they saw or heard” rather than “what they think.” The investigator must review the entire set of materials to make a judgment, and should not let the witness determine whether something constitutes harassment.

Confirmation area	Question example
date	Do you remember when that situation occurred?
location	Where did this take place at the time?
participant	Who was there?
Direct perception	What did you see or hear firsthand?
Content of the remarks	Do you remember any specific expressions or the intent behind the words?
action	What actions or situations occurred at that time?
Context	What happened before and after that situation?
Repeatability	Have you seen a similar situation before?
data	Are there any related messengers, emails, meeting materials, etc.?
Subsequent changes	Has there been any change in the work atmosphere or relationships since then?

It is best to start with open-ended questions to avoid leading to a conclusion all at once, and then proceed with clarification questions if necessary.

3. Avoid questions that speculate, evaluate, or take sides.

The most important thing to avoid during witness interviews is prompting the witness to evaluate the person involved. Such questions lower the credibility of the statement and can lead to a deterioration of the relationship or the spread of rumors after the investigation.

Questions to Avoid	Questions to change
Who do you think is lying?	What facts did you verify firsthand?
Is the person reported by the police originally that kind of person?	Have you ever seen a similar situation firsthand?
Is the reporter on the sensitive side?	What was the caller's reaction at the time?
Do you consider that to be harassment?	Do you specifically remember the remarks or actions at the time?
Was the team atmosphere always bad?	Were there any changes in work before or after that situation?
Everyone else knows that too, right?	Was there anyone else who saw the same situation?
Whose side are you on?	Please tell me only what you know personally.

Even when a witness says, “In my opinion…”, it is advisable for the investigator to record facts and opinions separately, rather than unconditionally excluding the opinion.

4. Allows the witness to state that they do not know what they do not know.

A witness may not be aware of the entire situation. They may have seen only a part of it or be unaware of the full context. In such cases, it is important to guide the witness so that they do not fill in the blanks based on speculation.

You may use the following guidance phrases during the interview.

It is okay to say that you do not know about matters you do not remember or have not seen firsthand. It is more helpful for the investigation if you only provide information you have personally verified, rather than speculation.

It is also recommended to distinguish them as follows when recording.

division	Recording method
I witnessed it firsthand	“The witness stated that they directly heard remark A during the meeting.”
Listen directly	“The witness stated that they heard the relevant details from the complainant on the day of the incident.”
Indirect message	The witness explained that the information was heard from another employee.
calculation	The witness stated that they do not know the exact circumstances but presume them to be so.
Memory unclear	Stated that he could not remember the exact date.
Unknown	Stated that they were unaware of the relevant matters

If you record things by mixing what you witnessed firsthand, what you heard, and speculation, it may become difficult to determine the facts later.

5. Interview records are kept based on facts.

When recording witness interviews, it is better to structure the information necessary for the investigation rather than writing it in as much detail as possible. However, if the record is written too briefly, it becomes difficult to verify later what questions were asked and what answers were received.

The record may include the following items.

division	Record contents
Interview Information	Date of interview, location, interviewer, witness, attendees
notification	Information on the purpose of the meeting, confidentiality, and prevention of disadvantage
Summary of the question	Key questions identified by the investigator
Summary of the answer	Key points directly stated by the witness
Cognitive pathway	Distinction between direct eyewitnessing, direct hearing, and indirect word.
Submission materials	Messenger, email, meeting materials, photos, etc.
Additional verification	Other references, verify materials necessary whether
Check records	Whether the witness confirmed the gist of the statement

It is best to write sentences based on facts rather than emotional evaluations or assertions. For example, rather than “the witness said that the accused is very bad,” it is appropriate to record it as, “The witness stated that the accused made remarks publicly pointing out issues to the complainant at least three times during the meeting.”

6. Restrict access to interview schedules and records.

Rumors about witness interviews can spread simply by the exposure of the schedule. It is advisable to avoid marking public calendars as “Harassment Investigation Witness Interview” or sharing the interview schedule in department group chats.

Management Items	Recommended direction
Schedule name	Use neutral expressions such as individual interviews and HR meetings.
location	A quiet space not exposed to the outside
participant	Minimum number of personnel required for the investigation
Invitation method	Private individual schedules or individual notifications
Archives	Event-specific restricted folders or secure storage
Access permissions	Necessary personnel such as investigators and HR managers
Sharing method	Restricted links or in-person viewing rather than email attachments
Copy management	Organize personal PC, messenger, and downloaded files

Since witness interview records may contain third-party statements and personal information, access rights must be managed to ensure they are not retained even after the investigation is concluded.

7. Check whether witness protection is provided after the interview.

Witnesses may feel burdened after the interview, worrying, "Will it become known that I cooperated with the investigation?" or "Will I face difficulties within the department?" Therefore, it is advisable to verify, if necessary, that there is no disadvantage or pressure even after the interview.

Confirmation items	Confirmation details
Exposure of the interview	Whether the interview schedule or the fact of attendance was known to those around you
Coercion and pressure	Whether the party or a colleague asked about or pressured the content of the statement
Work disadvantage	Whether there was exclusion from work, pressure regarding evaluations, or unfair instructions
Relationship burden	Whether there were rumors, distancing, or conflicts within the team
Additional statement	Is there anything additional you remember after the interview?
Need support	Whether HR/EAP guidance is necessary in cases of significant anxiety or burden

Although witness protection may not have the same structure as whistleblower protection, it may be necessary for the purpose of managing the situation to ensure that no disadvantages or pressure arise from cooperating with the investigation.

Common mistakes

The first mistake is Explaining the entire case in detail to a witness If you provide more information than the witness needs to know, the direction of the investigation may be exposed or the statement may be influenced.

The second mistake is Requesting a judgment from a witness Rather than asking questions like, “Do you think this is harassment?” or “Who do you think is right?”, it is better to verify the facts the witness directly saw and heard.

The third mistake is Recording a witness's conjecture as if it were a fact You must distinguish between what you witnessed firsthand, what you heard secondhand, what you estimated, and what you cannot remember.

The fourth mistake is Exposing the interview schedule as is on a public calendar Since the fact of an investigation can spread even with just the event name, it is recommended to use a neutral event name and private settings.

The fifth mistake is Widely sharing witness records with department heads or parties involved Witness statements must be managed only to the extent necessary for the purpose of the investigation, and the purpose of work coordination and the purpose of sharing statements must be distinguished.

The sixth mistake is Leaving the witness as they are after the interview This is because the witness may be pressured if the fact of their participation in the interview becomes known or if the party asks about the contents of their statement, so subsequent verification may be necessary if required.

If EAP support is needed

Witness interviews regarding workplace harassment are not an area that can be replaced by an EAP. Witness questioning, verification of facts, recording of statements, assessment of investigation results, protective measures, and follow-up personnel actions must be conducted in accordance with the company's official investigation procedures and legal standards.

However, the witness may feel burdened by participating in the interview, or may report anxiety, sleep problems, difficulty concentrating on work, or relationship tension after witnessing the incident. In such cases, the witness may be referred to an EAP as a supplementary channel.

division	role
Workplace harassment investigation	Verification of facts, review of protective measures, and follow-up personnel actions
Witness interview	Confirmation of facts and records based on direct observation and listening
HR & Grievance Handling Procedures	Interview scheduling, confidentiality, record management, prevention of disadvantage
EAP counseling	Support for witnesses' psychological burden, anxiety, and relationship difficulties
Emergency Route	Response to suicide/self-harm suggestions, risk of violence, and immediate safety risks

EAP guidance text can be used as follows.

If participating in witness interviews during a workplace harassment investigation causes psychological burden, anxiety, or relationship difficulties, you may utilize the EAP counseling channel. EAP does not replace the workplace harassment investigation or official company measures; it is a supplementary channel designed to support employees' psychological well-being.

However, in cases involving suggestions of suicide or self-harm, immediate safety risks, or risks of violence, do not respond solely with general EAP guidance; instead, you must first check emergency channels such as 119, 112, or the suicide prevention hotline 109.

Frequently Asked Questions

Q1. To what extent should I explain the details of the report to the witness?

It is advisable to explain only the scope necessary for the witness to state the facts. Sharing the entire structure of the case or the statements of others in detail may expose the direction of the investigation or influence the witness's statement.

Q2. What should I do if a witness refuses an interview?

Rather than proceeding with the interview coercively, it is advisable to reiterate the purpose of the interview, confidentiality standards, and principles for preventing disadvantage, and to request cooperation in a manner that is feasible. If participation is difficult until the end, you can record the history of the interview request and the reason for non-participation, and review whether the facts can be supplemented with other materials or witnesses.

Q3. May I ask the witness whether it appeared to be harassment?

It is best to avoid this if possible. The investigator must comprehensively review the full facts, legal standards, and company regulations to determine whether harassment has occurred. For witnesses, it is appropriate to ask about remarks, actions, situations, and the context they directly witnessed or heard.

Q4. Is it permissible to share the witness's statement with the complainant or the accused?

It may be necessary to verify facts and provide opportunities for clarification to the extent required by the investigation procedure. However, care must be taken to ensure that the identities of witnesses, original statements, and unnecessary personal information are not shared verbatim. It is advisable to review the scope of sharing based on the specific case and procedure.

Q5. How detailed should the records of witness interviews be?

It is advisable to record the date and time of the interview, attendees, prior notice, main points of questions and answers, how you learned of the situation, submitted materials, and any additional verification items. However, it is safer to avoid excessively recording personal information, health details, speculative evaluations, or emotional comments about the person concerned beyond what is necessary.

Q6. Can witnesses also use EAP counseling?

Depending on the scope of EAP operations, reference persons may also utilize counseling. If a reference person experiences anxiety, burden, or relationship difficulties due to participation in the investigation, they may be referred to EAP counseling as a supplementary channel. However, it is recommended to manage counseling content separately from the investigation data.

Next step

While interviewing witnesses in workplace harassment cases is a procedure that enhances the credibility of an investigation, inappropriate questioning and recording methods can lead to secondary harm and the spread of rumors. HR and investigation personnel must first organize what to ask the witness, what to record, and who will have access to the records.

First, it is recommended to check the following three things.

Priority check items	Confirmation details
Question criteria	Is there a fact-based questionnaire based on direct observation and hearing?
Recording standards	Do you distinguish and record direct cognition, indirect message, presumption, and unclear memory?
Confidentiality	Are interview schedules, statements, and access to records restricted?
