In Part 3, we argue for three principles to guide our organizing. First, we need action. In taking action we change the world, but this struggle also changes us. Action should furthermore be a core part of what we do rather than a last resort. Second, we need to find ways to build a rank and file that keeps union bureaucracy in check, developing methods and skills to apply pressure inside unions as well as the confidence to act for ourselves. Third, enacting democracy means understanding organizing as a process. We want to win, and this necessitates having as many co-workers involved in our struggle as possible. This might mean decisions not going our way or having to learn hard lessons. Struggle is not only about winning, it is also a process that builds new leaders and a confident rank and file. It is through struggle that we become a force capable of changing the world. We also introduce the idea of workers’ inquiry. This builds upon the idea that we, as workers, are best placed to both understand and change our own work.
