Sdružení československých horníků ('Czechoslovak Miners Association', abbreviated SČH) was a Syndicalist mine workers trade union in Czechoslovakia.
[2] Whilst initially the revolutionary syndicalists of SČH had operated more or less independently, the union was tied closer to the Czechoslovak Socialist Party as it faced police repression and its members struggled with economic hardship.
[2] When Stanislav Kostka Neumann led a split in the Czechoslovak Socialist Party in 1920 and organized the Union of Communist Groups, a minority of SČH members joined him.
[2] On December 11–15, 1920 workers across Czechoslovakia organized a general strike in response to the police attack on the Rudé právo newspaper office in Prague.
[5] SČH took part in the general strike of miners in Bohemia that lasted from the end of August to early October 1923.
