Massive strikes that are hard to contain got use the 8 hour work day, weekends and a lot of labor rights. Civil right movements won only because a huge portion of them were militant (back then even the National Rifle Association supported banning guns).
A violent status quo necessitates violence to achieve change.
The suffrage movement in the UK also had a militant component:
> The tactics of the [Women’s Social and Political Union] included shouting down speakers, hunger strikes, stone-throwing, window-smashing, and arson of unoccupied churches and country houses. In Belfast, when in 1914 the Ulster Unionist Council appeared to renege on an earlier commitment to women's suffrage,[27] the WSPU's Dorothy Evans (a friend of the Pankhursts) declared an end to "the truce we have held in Ulster." In the months that followed WSPU militants (including Elizabeth Bell, the first woman in Ireland to qualify as a doctor and gynaecologist) were implicated in a series of arson attacks on Unionist-owned buildings and on male recreational and sports facilities.
This influenced the US suffrage movement, like https://en.wikipedia.org/wiki/Women%27s_suffrage_in_the_Unit... , even during WWI: "groups like the National Woman's Party that continued militant protests during wartime were criticized by other suffrage groups and the public, who viewed it as unpatriotic."
