FK Radnik was founded in 1948 in the town of Hadžići. In the following years the club played variably until the season 1971–72, when led by manager Ivica Petković took the first place in the Sarajevo zone, gaining the right to play in the Yugoslav Second League (Group South). In the 1973–74 season, the club got relegated back to the republic league.
Golden years
At the beginning of the Bosnian War, the club stopped all of its activities. Finally in 1994, in the free part of Hadžići, in Pazarić, former club players started an initiative to restart the club.
In the 1995–96 season, the club finished in 1st place in the Second League of Bosnia and Herzegovina (Group South) and got promoted to the First League. In its only top tier season, the 1996–97 season, Radnik finished in last place, recording 1 win, 1 draw and 28 losses. In those two seasons, Radnik managed club legend Sedik Fejzić (1995–96 season) and former Radnik Hadžići player Abdulah Oruč (1996–97 season).[1]
Present
Since the 1996–97 relegation, the club had its ups and downs, got relegated from the First League of FBiH in the early 2000s and had played in the Second League of FBiH (Group Center), though they were one of the best clubs in the league and on several occasions were close to promotion.
In the 2009–10 season, Radnik won the Second League of FBiH (Group Center) and got promoted back to the First League of FBiH, but after only one season of First League football since 2005, the club got relegated from the league in the 2010–11 season.
After nine years of their first promotion, in the 2018–19 season, under the guidance of local manager and also former club player Damir Beća, Radnik got once again promoted to the First League of FBiH two games before the end of the season, beating Pobjeda Tešanjka 6–0 at home on 22 May 2019, securing that spot.[2]
