"Minor acts of political sabotage" include such actions as excessive use of electricity or short-circuiting of telephone equipment, immobilizing vehicles (stealing parts, puncturing tires, contaminating gas tanks), material spoilage, and crop burning.
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.
