This is probably the biggest reason why I just like the idea of Syndicalism and don't call myself a Syndicalist. Another means for Syndicalism is to work through the Union, by general strikes. History has shown many examples of Syndicalist strikes which have been, at least partly, sucessful. When the Fascists began their revolution in Spain in the 1930s and the politicians and company leaders flead from the country, it were the Syndicalists who made resistance, by strikes, taking controll over factories, and arming themselves. In the 1920s the Kapp government in Germany was removed in a coup, and the politicians ran away, but it were the Syndicalists who made resistance by a general strike which forced the coup-makers to resign and reinstall the legal government.
Syndicalism is also anti-nationalistic.
It is a super-national organisation, which wants to unite all poeple in the world. The loyalty for a Syndicalist is not towards people of an arbitrarily defined nation or people, but to people with similar ideas all over the world. There are neither any reasons for a syndicalist to make war or use any other violence, unless his rights are threatened. Before WW1 the French Syndicalists wanted to make a deal with the largest Union in Germany that both would make a general strike if the countries would declare war against each other. The Germans refused, but it is an interesting thought to ponder what would have happened if some of the European unions would have made such a treaty before the great war.
