Workers' movement

[Tower of Bebel]

What defines the workers' movement? Which organizations are part of it and which are not?

[Yehuda Stern]

All organizations whose membership base is the working class - the trade unions, reformist parties that still have some connection to the class (for example, definitely the British LP, but not the Greek Synaspismos), and of course the revolutionary party. Centrist parties can also sometimes be part of the workers movement, but more often than not their base is in the middle class.
