Certain people face a greater chance of severe harm from an exposure: pregnant and breastfeeding women, infants, older people, people with disability, and people medically prone to infection or allergy, including immunocompromised workers; an asthmatic is more susceptible to organic dust, and a person on cancer treatment struggles to fight off everyday infections. Such people are present in every workplace, not just hospitals and aged care homes. Extra thought may also be needed for workers who are young or from culturally and linguistically diverse backgrounds and need tailored communication, and for workers who would be hit harder in other ways, for example because they have no paid sick leave. The PCBU must do everything it reasonably can to manage the risks to workers and others, including vulnerable people whose needs it knows of or has been told about: a pregnant veterinary nurse, for example, needs extra precautions such as changed duties or more PPE against toxoplasmosis. During an outbreak that spreads easily, measles in a school say, or when a worker's circumstances change so that an exposure would hurt them more, temporary adjustments such as working from home or a different role may be called for, within the limits set by industrial relations, equal opportunity and disability discrimination law. Adjusting for individuals never replaces the duty to reduce risk for the whole workforce, and any medical history a worker provides stays confidential under privacy and anti-discrimination rules.
