SZNO (Stalnija-Zelezhna Novi Otonik, English: Steel and Iron of Novi Otonik) is a Kresimirian trade union headquartered in Novi Otonik, focusing on steel and ironworks. It is a regulated and permitted union under the constitution, which forbids non-sanctioned trade unions from operating.
It was founded in 1956, coinciding with the increasing industrialisation of the Kresimirian economy, especially in Novi Otonik and the surrounding eastern towns.
Possibly the most well-known member of SZNO is Ljubo Sanjakorin, leader of Blue Dawn from 1982 to 2002. Sanjakorin refused to quit his union membership when elected as a Senator in 1979, something that then-Chair of the Assembly Ante Brov supported and defended. Under pressure from Chancellor XXXX, Sanjakorin later left the union in 1984, but under his leadership Blue Dawn nevertheless implemented many worker-friendly policies, and SZNO remained strongly aligned with Sanjakorin throughout his tenure.
