A union organizer (or union organiser) is a type of trade union official. In most unions, the organizer's role is to hire groups of workers under the organizing model. In other unions, the organizer's role is largely that of servicing members and enforcing work rules, similar to the role of a shop steward. In some unions, organizers may also take on industrial/legal roles such as making representations before Fair Work Australia, tribunals, or courts.
