Fatigue and shift-work incident: NSW workers compensation guide

Shift start and finish, overtime, breaks, on-call periods and turnaround time. Task demand, night work, heat, noise, commute and sleep opportunity. The task history should quantify force, weight, repetition, duration, posture or exposure rather than rely on a label such as “overuse”.

Transport, healthcare, emergency and security workers on nights or rotating shifts. Construction, mining, manufacturing and warehouse workers on long shifts or overtime. Rosters and role records can identify who performed or observed the same work cycle.

Injury in a fatigue-related incident. Psychological injury. A symptom label does not replace a diagnosis or a reasoned opinion linking that diagnosis to the measured work history.

Rosters, timesheets, overtime, on-call and swipe records. Vehicle, machine or system event data and CCTV where relevant. Early records should show when symptoms began, changed and were reported, even where there was no single accident date.

• Near-miss, incident, supervisor and fatigue reports.

Rosters, timesheets, overtime, on-call and swipe records. Vehicle, machine or system event data and CCTV where relevant. The strongest task history connects objective work records with the symptom and treatment chronology.

• Near-miss, incident, supervisor and fatigue reports.
• Medical history of sleep, medication, illness and post-incident diagnosis.

Diagnosis of the injury or illness rather than fatigue alone. Clinical history of sleep, roster, medication and symptoms. Medical causation evidence should address the diagnosis, measured work exposure, pre-existing conditions and relevant non-work factors.

• Opinion connecting fatigue or shift work to the event where medically relevant.

Rosters allowed adequate rest and the worker did not report fatigue. Personal sleep, medication, alcohol, illness or another job caused fatigue. The insurer’s written reasons should be answered with evidence directed to the actual causation or eligibility issue.

Treatment follows the diagnosed physical, psychological or sleep-related condition. Roster change may be part of rehabilitation but is not itself proof of the claim. Treatment and restrictions should be tied to the accepted diagnosis and the work factor that needs to be reduced or avoided.

Restrictions may concern night shift, shift length, overtime, driving and safety-critical work. Capacity should consider cumulative roster and recovery, not one isolated shift. Sustainable capacity depends on the complete shift and repeated exposure, not whether one movement can be demonstrated once.

Fatigue itself is not a WPI category. Any stable accepted physical, neurological or primary psychological impairment is assessed under its own method. The assessment must follow the method for the accepted diagnosis, such as Injury in a fatigue-related incident, Psychological injury, Head injury. WPI is assessed after stabilisation using the NSW method for the accepted diagnosis; exposure duration or pain alone does not set a percentage.

A road accident during work may also require CTP investigation depending on the circumstances; commuting rules should not be assumed. Any employer-negligence, TPD, CTP, dust-disease or other pathway is separate and depends on its own facts and eligibility rules. Any other compensation or insurance pathway remains separate and has its own eligibility rules.

Organise a task-by-task exposure chronology with weights, repetitions, duration, posture, equipment or contaminant details. Compare the insurer’s written reasons with the medical diagnosis, prior history and contemporaneous workplace records. The purpose is to match the disputed decision to reliable work and medical evidence, not to promise an outcome.
