Sabotage was adopted by the General Federation of Labor of France in 1897 as a recognized weapon in their method of conducting fights on their employers. But sabotage as an instinctive defense existed long before it was ever officially recognized by any labor organization. Sabotage means primarily: the withdrawal of efficiency. Sabotage means either to slacken up and interfere with the quantity, or to botch in your skill and interfere with the quality, of capitalist production or to give poor service. Sabotage is not physical violence, sabotage is an internal, industrial process. It is something that is fought out within the four walls of the shop. And these three forms of sabotage -- to affect the quality, the quantity and the service are aimed at affecting the profit of the employer. Sabotage is a means of striking at the employer's profit for the purpose of forcing him into granting certain conditions, even as workingmen strike for the same purpose of coercing him. It is simply another form of coercion.
There are many forms of interfering with efficiency, interfering with quality and the quantity of production: from varying motives -- there is the employer's sabotage as well as the worker's sabotage. Employers interfere with the quality of production, they interfere with the quantity of production, they interfere with the supply as well as with the kind of goods for the purpose of increasing their profit. But this form of sabotage, capitalist sabotage, is antisocial, for the reason that it is aimed at the good of the few at the expense of the many, whereas working-class sabotage is distinctly social, it is aimed at the benefit of the many, at the expense of the few.
Working-class sabotage is aimed directly at "the boss" and at his profits, in the belief that that is the solar plexus of the employer, that is his heart, his religion, his sentiment, his patriotism. Everything is centered in his pocket book, and if you strike that you are striking at the most vulnerable point in his entire moral and economic system.
