Every strike brings thoughts of socialism very forcibly to the worker’s mind, thoughts of the struggle of the entire working class for emancipation from the oppression of capital.
A strike teaches workers to understand what the strength of the employers and what the strength of the workers consists in; it teaches them not to think of their own employer alone, but of all the employers, the whole class of capitalists and the whole class of workers.
V.I.Lenin, On Strikes
