Summary
In July 1927, Austrian Social Democrats called a general strike in Vienna to prevent further violence after a controversial acquittal sparked riots. The strike lasted from July 15 to July 18 and successfully prevented open civil war between Viennese workers and the national government. The Social Democrats also gained votes and representation in the 1928 elections.
Background
In Vienna in 1927, the Social Democrats held a local majority but faced opposition from the federal government and rural fascist-leaning areas. A federal court acquitted three members of the militaristic Front-Fighters for murdering a worker and a boy, sparking outrage among Viennese workers. The Social Democrats called a general strike to prevent the resulting protests from escalating into civil war.
What happened
On July 15, 1927, workers learned of the acquittal and left their posts, marching on Parliament. [source: nv-database] Power station workers struck, stopping trolleys. [source: nv-database] Police attacked with sabers and revolvers, and protesters built barricades, stormed the Ministry of Justice, and set fires. [source: nv-database] At 7pm, the Social Democratic Party and Trade Union Council called a general strike, demanding workers stay home and avoid violence [source: nv-database]. On July 16, the strike continued successfully, though six communist youth were killed, possibly by the Socialist Republican Guard [source: nv-database]. On July 17, the general strike ended after news that the fascist-leaning Heimwher militia planned to come to Vienna if the communications strike continued [source: nv-database]. The communications strike ended at noon on July 18, and the Social Democrats entered parliamentary talks.

Outcome
Verdict: partial.
The strike prevented open civil war between Viennese Social Democrats and the national government, and the Social Democrats gained votes and representation in the 1928 elections. However, the strike did not achieve broader political change, and violence had already caused significant loss of life and property. [source: nv-database]
