The name Radnički means " Labourers " in Serbian and its roots come from the relation with the Labour movement that the clubs had during the first half of the 20th century . Their often mentioned slogan is : ' '' " Radnička deca , radnička braća " ' '' , which translates to " Workers children , workers brothers " . Another connection is their anti-fascist attitude through similar tragedies which took place in both cities during the World War II . In Niš the Bubanj massacre and in the city of Kragujevac the Kragujevac massacre , both committed by Nazi German soldiers , which had in both cities a significant influence on subsequent generations . All reasons , why the first top tier match between these clubs ended during the 2012 – 13 season especially in a respectful and peaceful atmosphere for each other , although they not played against each other for a long time
