A witness may remember a conversation very differently from the worker, supervisor or manager involved. That does not automatically make one account unreliable. In complex claims, interviewing witnesses for complex workers’ compensation matters is about gathering clear, relevant evidence without assuming the outcome before the facts have been properly tested.
Witness evidence can affect how an employer, insurer or self-insured organisation understands an incident, reported symptoms, workplace interactions, notice of injury, suitable duties, or the events leading to a psychological injury claim. Handled poorly, an interview can create confusion, compromise confidence in the process and leave significant gaps in the evidence. Handled well, it gives decision-makers a reliable account of what a person directly saw, heard, did or was told.
Why witness interviews require care in complex claims
Workers’ compensation matters are often not confined to a single event. A physical injury may involve differing accounts of how work was being performed, what equipment was available, whether a hazard had been reported or what assistance was offered afterwards. Psychological injury matters may involve a sequence of workplace interactions, performance discussions, team conflict, workload changes and communications over time.
A witness interview is not an opportunity to collect opinions that support a preferred position. Its purpose is to establish the witness’s own evidence, distinguish direct knowledge from assumption or workplace hearsay, and identify material that may confirm, qualify or contradict other available information.
This distinction matters. A witness who says, “Everyone knew she was struggling”, may be expressing a genuine concern, but a useful interview needs to explore what that person personally observed. What did they see? When did they see it? What words were used? Who else was present? Did they report the concern, and is there a record? Specific detail is usually more valuable than broad characterisations.
Prepare before interviewing witnesses for workers’ compensation
A disciplined interview begins before the witness is contacted. The interviewer should first understand the issue that needs to be examined and review the available material, such as the claim form, incident report, relevant correspondence, roster information, policies, medical certificates and contemporaneous notes.
Preparation does not mean forming a conclusion. It means creating a focused line of enquiry and avoiding a conversation that is either too broad to be useful or so leading that it influences the witness’s answer. In complex matters, a chronology is particularly helpful. It can identify disputed dates, missing periods, key conversations and the people who may have direct knowledge of each event.
The interview plan should identify the witness’s connection to the events and the subjects that require clarification. It should also allow room for unexpected but relevant information. A supervisor may have been present at an incident, for example, but their evidence may also explain what was reported afterwards, what action was taken and whether suitable duties were discussed.
Confidentiality should be addressed in practical terms. Witnesses should understand that their information will be handled carefully and shared only as required for the claim process. They should not be promised absolute secrecy where the account may need to be considered by claim decision-makers or put to another person for a fair response.
Start with the witness’s own account
The strongest interviews generally begin with open questions. Asking “Please tell me what you recall about that afternoon” gives a witness space to describe events in their own words. Follow-up questions can then test the detail: “Where were you standing?”, “Who was present?”, “What was said next?” and “How do you know that?”
Leading questions can be useful for checking a specific point, but they should not be the main method of obtaining evidence. “The worker was upset after the meeting, wasn’t she?” suggests an answer. “What, if anything, did you observe after the meeting?” is more neutral and allows the witness to describe what they actually saw.
It is also essential to separate fact from interpretation. A witness may say a manager was aggressive. The interviewer should respectfully ask what conduct led them to that view. Did the manager raise their voice, interrupt repeatedly, use particular words, stand close to the worker, or make a threat? The description of conduct is evidence. The label applied to it is a viewpoint that may or may not be supported by the surrounding facts.
Where a witness cannot recall, that answer should be recorded accurately. Pressing for a more definite response can reduce the quality of the evidence. Memory is affected by time, stress, repeated conversations and exposure to other people’s accounts. A careful process recognises these limits rather than treating uncertainty as a failure.
Test the detail without treating the witness as an opponent
A respectful interview can still be thorough. If an account differs from a document or another witness’s evidence, the discrepancy should be explored in a neutral way. The interviewer might say, “The roster shows your shift started at 7.00 am. Does that assist with your recollection of when this occurred?” This gives the witness an opportunity to explain, correct or maintain their account.
The same approach applies where a witness provides second-hand information. Rather than dismissing it, clarify who made the statement, when it was made, the words used as far as the witness recalls, and whether the original source can be interviewed or located. This assists the decision-maker to give the information appropriate weight.
A written statement or detailed interview note should be reviewed for accuracy. The witness should have a reasonable opportunity to correct material errors, clarify ambiguous wording and confirm that the record fairly reflects their account. The final record should identify the date, participants, method of interview and any documents shown to the witness.
Queensland claims: identify who manages the claim early
In Queensland, the practical pathway can differ depending on whether the employer is scheme-insured or self-insured. A scheme-insured employer’s claim is generally managed through the scheme insurer, while a self-insured employer manages claims through its own approved claims function. This affects who coordinates information, communicates with stakeholders and makes claim decisions.
Workers should identify early who is managing their claim and ask for the correct contact details. This is especially useful where workplace facts, medical information and return-to-work arrangements are developing at the same time. Treating doctors and other health providers should also be given clear instructions about where reports, certificates and relevant information should be sent. Information sent to the wrong place can delay a review of the claim or leave decision-makers working from an incomplete file.
For employers and return-to-work coordinators, this clarity helps prevent witness material becoming disconnected from the broader evidence. A supervisor’s account of an incident may need to be considered alongside medical information, workplace records and the worker’s own account. Each source has a different purpose. None should be treated as conclusive in isolation.
From witness evidence to clear reasons for decision
Witness interviews are only useful if their evidence can be traced through the decision-making process. A sound Reasons for Decision document is more than a statement of the outcome. It should set out the relevant factual and medical information considered, explain the applicable scheme requirements, address material competing information and show why particular evidence was given weight.
For example, if a witness account is preferred because it was contemporaneous, detailed and consistent with objective records, that reasoning should be stated plainly. If a witness has limited direct knowledge, or recalls events only after discussing them with others, that limitation should also be explained. Transparency does not require every minor inconsistency to be given equal significance. It requires material issues to be identified and dealt with fairly.
This approach supports both workers and employers. A worker should be able to understand what information was considered, how it was assessed and what the outcome means for their claim. Employers need a clear evidentiary pathway between the information obtained and the action or decision taken. A person who was not involved in the matter should be able to follow the reasoning without having to guess at the steps in between.
When an independent process adds value
Independence can be particularly valuable where the allegations involve senior staff, multiple witnesses, entrenched workplace conflict or a significant difference between accounts. It may also assist when an existing file contains informal notes, incomplete statements or conclusions that are not clearly connected to the available evidence.
A structured review can identify who has direct knowledge, what questions remain unanswered, whether each person has been treated fairly and whether the evidence supports the conclusions being considered. MAKAL’s approach is grounded in Workplace Facts. Fair Process. Clear Outcomes.
The purpose is not to make a difficult claim feel simple. It is to make the evidence clearer, the process more respectful and the next decision easier to explain.
