These unions merged into the one larger union to pool their expertise and resources, so they could provide members with a larger range of quality services.

[2] In June 2019, the Fair Work Commission approved a vote on the proposed merger between the two unions which will be held in August.

[3] On 30 August 2019 the Australian Electoral Commission declared the result of the vote, with just over 95% of members supporting the amalgamation.

As a result of the amalgamation, the National Union of Workers will be deregistered as part of the merger and its members folded into the larger United Voice.
