Shop Distributive and Allied Employees Association

The Shop, Distributive and Allied Workers' Union (SDA) is one of Australia's largest trade unions, representing workers across various sectors including retail, fast food, and logistics. Formed through significant mergers in the 1980s, the union has grown under notable leaders like Joe de Bruyn, known for his influence within the Labor Party.

The SDA operates with a moderate approach to industrial relations, focusing on growth and responsible negotiations. It has faced criticism for underpayment issues following legal rulings and allegations of maintaining close ties with employers. Politically aligned with the Australian Labor Party's Right faction, the union holds significant influence, contributing substantial financial support and having key representatives in federal parliament.

Despite its progressive stance on many labor rights, the SDA historically took socially conservative positions but has since adopted neutrality on issues like same-sex marriage. Overall, the SDA remains a pivotal force in shaping Australia's industrial and political landscape through advocacy and policy influence.
