When dealing with reports and incidents of workplace violence it is important that the investigative process is commenced in a timely manner and is properly documented, appropriately communicated to all necessary parties, and protects the privacy and confidentiality interests of the parties directly involved and results in suitable disciplinary action. A seriously flawed or negligent investigation can be significant and costly to employers. Workplace investigations relied upon by employers, and subsequent civil or human rights proceedings, will be subject to intense scrutiny.
The key to an effective workplace investigation is to obtain as much information as possible. The investigation should include interviews with every person identified as potentially having information. The investigation should follow up on every lead or related allegation. This may result in people being interviewed on multiple occasions.
