The union representing Streets ice-cream factory workers will urge the public to boycott its products including Paddle Pop, Golden Gaytime and Magnum over the summer if the company terminates their agreement on pay and conditions.

The Australian Manufacturing Workers Union said it was planning to organise a boycott of Streets ice-creams including the icon Paddle Pop if multinational Unilever, which owns Streets, proceeded with its application in the Fair Work Commission to terminate the current enterprise agreement.

Unilever, the multinational company that owns Streets, wants to terminate an expired enterprise agreement covering factory workers in Sydney's Minto.

The boycott would be similar to the one imposed on beer giant Carlton and United Breweries products in 2016 during a long-running industrial dispute. The public supported the boycott on products including Carlton Draught, Carlton Dry, VB, Crown Lager and Pure Blonde.

AMWU secretary Steve Murphy said Streets workers in the Sydney suburb of Minto had raised serious concerns about the threat of a significant pay cut if their enterprise agreement was terminated and they were forced back onto the award safety net.
