An HSR is a worker who has been elected by the members of their work group to represent them in health and safety matters.

Any business can choose to have HSRs and they are a well-established way to support worker engagement and participation.

HSRs are elected by a work group, which is a defined group of workers who work for the PCBU. The work group can be the whole workplace or it can be workers grouped by work areas, occupations, work sites or other arrangements. How a work group or work groups are organised will depend on what is effective for the PCBU and the workers, given the structure of the business or undertaking.
