Workplace Harassment · Investigation Operation Checklist

Under investigation for workplace harassment
Please manage the standards for preventing secondary damage as well.

Preventing secondary harm during workplace harassment investigations is a management item as important as the investigation itself. HR personnel must ensure that whistleblowers and victimized employees do not experience disadvantages, rumors, pressure, retaliation, deterioration of relationships, or excessive repetitive testimony during the investigation process. Separation measures, confidentiality protection, interview methods, scope of information sharing, record management We need to check together.

short answer

We must manage not only the fairness of the investigation but also the additional burdens incurred during the investigation process.
The core flow is: initiation of investigation → verification of need for protection → limitation of information sharing scope → refinement of interview methods → monitoring for disadvantages and pressure → record keeping → post-investigation recovery support.

🕒 When will it be applied?

The checklist for preventing secondary harm during a workplace harassment investigation is necessary in the following situations.
situation
Items to check by the person in charge
Workplace harassment report received
Confirmation of the need for protection of whistleblowers and victimized workers, etc.
Launch of official investigation
Investigator, interview schedule, and scope of information sharing
The complainant and the accused are in the same department.
Review of the necessity of separating workspaces, reporting lines, and work touchpoints
Conducting interviews with witnesses
Information on the intent of confidentiality protection and prohibition of disadvantage to witnesses
Spreading rumors within the department
Check if investigation-related information is being shared unnecessarily
Occurrence of protest or pressure by the accused
Verify whether additional burdens are placed on the whistleblower, victimized workers, etc.
Investigation schedule displayed on calendar/messenger
Adjustment of disclosure scope for event name, attendees, and venue information
Before and after notification of investigation results
Check for retaliation, exclusion, or deterioration of relations during the follow-up process
After the conclusion of the investigation
Confirmation of return to work, job reassignment, psychological burden, and organizational recovery support
Preventing secondary damage is not a measure necessary only after a report has been confirmed as fact. It is advisable to manage the situation at all stages—before, during, and after the investigation—to ensure that the reporter and the victimized worker do not suffer additional disadvantages or psychological burdens.

🧭 What an HR Manager Should Do

STEP 01

We first determine whether protection is necessary before commencing the investigation.

When a report of workplace harassment is received, the HR representative must investigate the facts and simultaneously determine whether protection is necessary.
Even before the investigation results are released, additional burdens may arise if the complainant and the accused continue to work in the same space, or if the accused can influence the complainant's performance evaluation, approvals, attendance, or reporting lines.
Confirmation items
Confirmation question
Business contact points
Must the complainant and the respondent continue to perform the same duties?
Report line
Does the accused have the authority to approve, evaluate, or direct the complainant?
spatial contact point
Do you keep running into each other in the same office, meetings, or group messenger?
psychological burden
Do the complainants or affected workers, etc., complain of difficulties in performing their duties?
Concerns about retaliation
Is there a possibility of disadvantage, pressure, coercion, or rumors occurring after reporting?
Personal choice
Was the opinion of the affected workers, etc., regarding the method of protective measures confirmed?
Protective measures must not isolate affected workers or relocate them against their will. While various options should be considered, a process to confirm the wishes of the affected workers is necessary.
STEP 02

Limit the scope of information sharing from the beginning.

Secondary damage can occur from the moment investigation details are unnecessarily shared. Therefore, it must be determined who can know what information immediately after a report is received.
Shared with
Examples of shareable scope
Points to note
investigator
Report details, interview records, and related evidence
Access restriction
HR Manager
Status of investigation, whether protective measures are necessary
Minimize sharing detailed statements
Department Head
Request for cooperation regarding work schedule adjustment and meeting
Caution regarding the sharing of details of reports and statements
witness
Personal Interview Schedule and Confidentiality Notice
Prohibition of sharing information with other reference persons or parties
The person reported
Fact verification items within the scope necessary for the investigation
Considering the balance between whistleblower protection and the right to defense
Management
Significant risks, action directions, and decision requirements
Minimizing personally identifiable information
In particular, you must be careful to prevent information from being exposed in group messengers, public calendars, shared drives, and email CC settings.
STEP 03

Ensure that the interview method does not cause secondary harm.

While investigation interviews are a procedure for verifying facts, the way questions are asked can place an additional burden on the complainant or the victimized worker. It is advisable to ask questions in a way that confirms the situation rather than assigning blame.
division
Recommended direction
Interview location
A quiet place not exposed to the outside
Schedule name
A neutral name that does not reveal the details of the investigation on the calendar
participant
Limited to the minimum number of people required
Questioning method
Focus on fact-checking rather than blame and interrogation
Repetitive statement
Organize the record sharing system to avoid having to repeat the same information multiple times.
rest
Provide breaks during long consultations
soapstone
Review the availability of a reliable companion if necessary.
Check records
Providing an opportunity to verify the gist of the statement
If emotions become heightened or anxiety reactions occur during the interview, it is advisable to consider taking a break, rescheduling, or referring the patient for counseling rather than forcing the interview to continue.
STEP 04

We also provide confidentiality standards to witnesses.

While witness interviews are crucial for verifying facts in workplace harassment investigations, widely sharing the investigation details with witnesses can lead to the spread of rumors.
Guide Items
Information
Purpose of the interview
Limited interview to verify facts
Confidentiality
Instructions to avoid unnecessarily sharing investigation details and interview facts.
Prohibition of disadvantage
The point of managing the situation so that participation in the interview does not result in disadvantages.
No speculation
Instructions not to make assumptions or convey unverified information
Prohibition of retaliation and pressure
Instructions to avoid pressuring the whistleblower, victimized workers, and other witnesses.
Additional reporting channels
If you remember anything additional after the interview, please convey it to the designated person in charge.
You must distinguish between information that a reference needs to know and information that they do not need to know.
STEP 05

We verify that no adverse changes occur for the whistleblower and the victimized worker, etc.

Secondary harm does not only manifest as major measures such as clear-cut disciplinary action or dismissal. It can also appear in forms such as exclusion from work, exclusion from meetings, pressure regarding performance evaluations and attendance, rumors, and deterioration of relationships.
Confirmation items
example
Task assignment
Whether excluded from key duties after the report
Working environment
Is the psychological burden significant from constantly running into each other in the same space?
Meetings and communication
Whether to be excluded from meeting invitations and work sharing
Evaluation and attendance
Whether evaluations or attendance management have become excessively strict since the report
Rumors and criticism
Whether words blaming the whistleblower are spreading within the department
Coercion and pressure
Whether being asked to withdraw the report, reach a settlement, or remain silent
Deterioration of relationship
Whether colleagues or managers are overtly distancing themselves
If such changes are confirmed, it is advisable not to view them merely as a "culture issue," but to re-examine investigative protection measures and standards for preventing adverse treatment.
STEP 06

We also clearly inform the accused of the investigation principles.

Preventing secondary harm does not mean protecting the whistleblower alone. The accused must also be clearly informed of investigation procedures, confidentiality, prohibition of retaliation, restrictions on contacting witnesses, and methods of verifying facts.
Guide Items
Information
Purpose of investigation
Procedure to objectively verify the facts
Opportunity to make a statement
The fact that an opportunity for explanation is provided to the extent necessary
Confidentiality
Instructions not to share investigation details and party information externally
Contact restriction
Instructions not to directly contact or pressure reporters, victimized workers, etc.
Prohibition of retaliation
The point that no disadvantages should be imposed for reasons of reporting, making statements, or cooperating.
Submission of materials
Method of submitting materials to support your explanation
When notifying the accused of the fact of an investigation, care must also be taken to ensure that unnecessary personal information or sensitive statements of the complainant are not excessively conveyed.
STEP 07

Investigation records are kept based on facts, and access rights are restricted.

Workplace harassment investigation materials may contain sensitive information, such as reports, statements, supporting evidence, allegations of psychological distress, and relationship conflicts. Therefore, records should be fact-based and kept to the extent necessary, and access permissions must be restricted.

⚠️ Common mistakes

POINT 01

Delayed review of protective measures based solely on investigation fairness

Even if the facts have not been established, it is advisable to first verify the work contacts, reporting lines, and psychological burdens of the complainant and the victimized worker during the investigation period.
POINT 02

Excessive sharing of investigation details with the department head

While a department head may need to know everything for work coordination, they do not need to know all the details of the report and statement. The purpose and scope of sharing must be limited.
POINT 03

Meeting schedules being exposed on public calendars or as meeting room names

If the details of the investigation are revealed in the event name, the fact of the investigation may become known to those around you. It is recommended to use a neutral event name and set it to private.
POINT 04

Explaining too much of the investigation details to the witness

A witness is someone who simply needs to state the facts they know; they are not someone who needs to be shared with the entire structure of the case.
POINT 05

Not providing the reported party with guidelines on contact restrictions and prohibitions on retaliation

Directly contacting the complainant or witness to ask for clarification or pressure them may lower the credibility of the investigation and cause secondary harm.
POINT 06

Stopping management after the investigation is concluded

Since concerns regarding exclusion from work, deterioration of relationships, rumors, and retaliation may persist even after the investigation results are notified, follow-up verification may be required for a certain period.

💬 When EAP support is needed

Investigating workplace harassment and taking measures to prevent secondary harm are not areas that an EAP can replace. Fact-finding, protective measures, disciplinary reviews, prevention of adverse treatment, and record keeping must be conducted in accordance with the company's official procedures and legal standards.
However, during the investigation process, complainants, affected workers, witnesses, managers, and investigators may experience significant psychological burden. In cases of anxiety, sleep problems, difficulty concentrating on work, interpersonal tension, or a heavy burden of participating in the investigation, EAP may be recommended as a supplementary channel.

Emergency response
Prioritize the company's crisis response procedures and appropriate emergency support channels in the event of an immediate safety risk.
If you require counseling due to psychological burden, anxiety, sleep problems, or relationship difficulties during the workplace harassment investigation process, 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.
If an immediate safety risk is suspected, do not respond solely with general EAP guidance; instead, you must first identify the company's internal crisis response procedures and appropriate emergency support channels.

❓ Frequently Asked Questions

Q1. Should separation measures be taken even before the investigation results are released?

Even before the investigation results are finalized, appropriate measures such as changing the workplace, providing paid leave, or adjusting duties may be considered if there is a need for protection. However, it is advisable to determine the method of action by confirming the wishes of the affected workers and their work situation together.

Q2. Is it permissible not to take protective measures if the affected workers, etc. do not want them?

It is important to confirm the wishes of the affected workers. However, since the company must consider both safety and the possibility of further damage, it is advisable to explain various options and review the method with the least burden rather than unilaterally applying unwanted measures.

Q3. Is it permissible to reveal the identity of the informant to the witness?

Although the witness may already be aware of the information, it is advisable for investigators to avoid unnecessarily sharing information about the complainant or victimized workers. It is safer to have the witness provide information only to the extent necessary for their statement.

Q4. To what extent must the reported details be disclosed to the accused?

You may provide the accused with information within the scope necessary for verifying the facts and providing clarification. However, considering the protection of the whistleblower, the safeguarding of sensitive information, and the prevention of obstruction of the investigation, you must exercise caution to avoid excessively conveying unnecessary personal information or detailed statements.

Q5. What should I do if the department head keeps asking about the investigation status?

Department heads must distinguish between information they need to know due to work adjustments and information they are simply verifying out of curiosity. It is advisable for HR to provide only the fact that an investigation is underway, matters requiring cooperation, and confidentiality standards, while limiting detailed statements or information that constitutes evaluations of the parties involved.

Q6. What needs to be verified when the whistleblower returns to the team after the investigation?

Upon returning, it is advisable to check for exclusion from work, exclusion from meetings, rumors, an uncomfortable atmosphere, contact with the reported individual, and the department head's management style. If necessary, HR or a designated person may schedule follow-up verifications for a certain period.

    조사 종료 후에도 업무 배제나 소문, 관계 악화가 없는지 확인해야 한다는 부분에 공감됩니다. 결과 통보로 끝내기보다 일정 기간 사후 점검이 필요해 보입니다.

    참고인 면담을 진행할 때 비밀보호 기준을 어디까지 안내하시나요? 참고인에게 너무 많은 정보를 주면 조사 내용이 퍼질 수 있고, 너무 적게 안내하면 면담 취지를 이해하기 어려울 것 같아서 궁금합니다.

    안녕하세요, 넛지EAP입니다.

참고인 면담을 진행할 때는 “왜 면담하는지”는 이해할 수 있을 정도로 안내하되, 신고자·피신고자 정보나 구체적인 신고 내용까지 자세히 공유하지 않는 것이 좋습니다.

예를 들어 “직장 내 괴롭힘 관련 내부 확인 절차에서 사실관계 확인을 위해 면담을 요청드린다”는 정도로 안내할 수 있습니다. 다만 어떤 사람이 신고했는지, 누구에 대한 조사인지, 다른 참고인이 어떤 진술을 했는지는 알려주지 않는 것이 안전합니다.

참고인에게는 면담 내용이 조사 목적 범위에서만 활용된다는 점, 면담에서 알게 된 내용을 다른 직원에게 공유하면 안 된다는 점, 진술했다는 이유로 불이익을 받아서는 안 된다는 점을 함께 안내하는 것이 좋습니다.

또 면담 기록을 남길 경우에는 참고인에게 기록 목적과 활용 범위를 간단히 설명하고, 진술 내용은 필요한 범위에서만 정리하는 것이 좋습니다.

정리하면, 참고인에게는 면담 목적·비밀유지 기준·불이익 금지 정도는 명확히 안내하되, 사건의 세부 내용이나 다른 사람의 진술은 공유하지 않는 방식이 가장 무난합니다.

    캘린더 일정명이나 회의실명 때문에 조사 사실이 노출될 수 있다는 부분이 현실적으로 와닿았습니다. 작은 조직에서는 일정 제목 하나도 조심해야 할 것 같아요.
  • Unknown User1
    2차 피해 예방은 조사 결과가 나온 뒤가 아니라 조사 시작 단계부터 봐야 한다는 점이 중요해 보입니다. 정보 공유 범위나 면담 방식만 잘못돼도 부담이 커질 수 있겠네요.
