United Trade Unions of Serbia "Sloga" was formed in 2008 by
Željko Veselinović. It had regularly organised
International Workers' Day walks. USS Sloga later organised media campaigns regarding workers' conditions, and had also criticised the economic model that has been pursued by
Aleksandar Vučić. It participated as a political organisation in the
2014 parliamentary election as part of the
Democratic Party (DS) coalition list. Veselinović became a member of the
National Assembly afterwards. USS Sloga regained its seat in the National Assembly following the
2022 general election. == Ideology ==
