Divisions organise workers in a specific areas of the economy, allowing for greater coordination of activities and the pooling of information across industries and services. Each Division is led and coordinated by a Divisional Organiser and an elected Divisional Committee.

Within each Division activities are further divided into Sectors dealing with Union operations in similar employments and associated services. Each Sector is led and coordinated by a Sector Organiser and an elected Sector Committee.

The work of Division and Sector Organisers is assisted by Industrial Organisers and Assistant Industrial Organisers as well as Union Administrative staff.

Each individual Union Section, with its own Section Committee and Shop Steward based on individual places of employment is assisted in its activities directly by the Sector Organiser and their staff.
