Workplace Investigation

A workplace investigation is a method used to determine what happened, whether a university policy has been violated, and who, if anyone, is responsible—it is not a legal proceeding. The Human Resources Business Partner (HRBP) will determine if a workplace investigation is necessary in order to address a staff member's complaint based on the nature and severity of the complaint and the information provided. In unique circumstances, the HRBP, in conjunction with the department and/or Behavioral Consultation Team (BCT), will evaluate whether an administrative leave is appropriate in circumstances which are deemed to be egregious or a safety concern (e.g. fitness for duty).

What follows is information about what to expect if you are a participant in a workplace investigation.

Workplace Investigation Roles

A workplace investigation generally includes the following roles:

Staff members are generally expected to participate in an investigation if requested. Non-participation in an investigation by a respondent or a witness will not prevent the investigation from proceeding. 

Northwestern policy prohibits the taking of retaliatory action against anyone who files a complaint or participates in a workplace investigation.

Investigation Process

The exact steps involved in any given workplace investigation may vary based upon the specificities of the case. What follows is an example of steps taken in a typical workplace investigation, but note that the process could vary based on each specific case.

  1. HRBP conducts intake interview with the complainant and reviews supporting evidence, if provided. If the HRBP determines that an investigation is necessary, the HRBP will notify the complainant and the appropriate department leadership accordingly.
  2. If it is determined that an investigation is not necessary, the complainant will be notified.
  3. HRBP collects information by interviewing the respondent and witnesses.
  4. HRBP determines findings after reviewing information collected in the interviews and the evidence provided by participants.
  5. HRBP communicates findings to appropriate department/unit leadership along with recommendations for next steps.
  6. The complainant and respondent are made aware of the findings and next steps.

Investigation Interviews

During investigation interviews, the complainant, respondent, and witnesses will have the opportunity to present information and material related to the situation. The investigator will ask questions related to the complaint, listen, and take notes. They will ask for the names of any other individuals who may have information or knowledge of the situation and about what happened. If necessary, the interviewee will also have the opportunity to respond to the information that will be relied upon and other information gathered.

In order to protect the integrity of the investigation, the investigator will request that you keep the information you share confidential until the investigation had concluded. 


The exact timeline is case-specific. Workplace investigations are approached as expeditiously as possible while completing the necessary due diligence. Complainants may contact the investigator to receive updates regarding the timeline.


The findings will be determined based upon a preponderance of the evidence, which is what more likely occurred than not, based on the information made available and that the investigator was reasonably able to gather.

The HRBP will first discuss the findings with appropriate department/unit leadership and will provide consultation in determining appropriate next steps. Recommendations, which are generally provided regardless of the outcome of the investigation, may include but are not limited to, training, adjustments to protocol/procedures, a facilitated meeting, corrective action, etc.

The complainant and respondent are made aware of the findings and next steps as it relates to each of them specifically, meaning that if the findings are substantiated and corrective action is sanctioned, the other party will not be made aware of the specifics.
