This work is a historical overview of trade unionism in Mexico, specifically in the period from 1914 to 1917.

Its particular relevance lies in being that necessary antecedent to know for an oppressed class since the times of the nascent industrialization in our country, the proletarian. Because it is not possible to understand the present if we do not take hold of our history, of the abuses committed against the labor sector, a reason that gives ample space to the birth of trade unionism.

In these pages is also the piece that would give the foundation to the electrical trade unionism, of vital importance as the axis of resistance of the Mexican working class. For this reason, in this book there is a key passage to understand both the struggles undertaken by the workers, as well as their absolute importance in these days to understand the attacks of neoliberalism against a class, since past times, hurt, such as the worker.
