Health and safety obligations in relation to fatigue
Under health and safety legislation, you have an obligation to take all reasonably practicable steps to ensure the safety of your workers. Therefore, causing or permitting workers to perform work in a fatigued state could expose you to liability for breaching health and safety legislation.

Tip: The Western Australian code of practice, Psychosocial hazards in the workplace, states that fatigue can be both a psychosocial hazard and the outcome of being exposed to psychosocial hazards, and it is a state of mental or physical exhaustion.
Important: Workers also have a responsibility to avoid putting themselves or others at risk from their work activities, including not performing work while fatigued.
