Prison labor is literally central to maintaining incarceration and mass incarceration in the United States. [...]

The historical record tends to favor the powerful, and we're talking about people who by just about every definition lack power. And so their materials, their records tend not to be preserved in archives, but they are still out there in smaller fragments. And so what I've been doing over the past several years is really piecing together from a variety of sources, everything I can find to sort of build a body of materials that are written by and represent and reflect the words and the priorities of these prison labor organizers

So my goal is to sort of add additional angles to understanding what went on and how did the people who were at the heart of these battles for prisoner labor rights, how did they see and understand what they were doing? How did they strategize, how did they react to and engage with people in power or other people on the ground? And what can that teach us about this really influential time in American prison history."

PERSONAL BIO 
I am an Associate Professor of Sociology & Criminology at the University of Denver. Through my research, I investigate the obscured experiences and struggles of working prisoners through ethnographic observations, interviews, and historical and archival analyses. I also engage with local, national, and international advocacy groups to help improve prison policy.

​My current research investigates the prison labor movement of the 1970s, through which American prisoners sought to unionize in pursuit of improved rights and protections. I document the rise and fall of this labor struggle behind bars, tracing its impacts on evolving penal policy, with insights for policymaking and organizing today. Future phases of this work will interrogate such organizing across international contexts.

RESEARCH FOCUS
History of prison labor, prisoner unions in the 1960s–1970s, underground newspapers (The Outlaw), labor organizing behind bars, cross-racial solidarity movements, legal battles over incarcerated workers’ rights, and the socio-legal roots of prison labor policy.

What this prison labor movement in the 1970s reveals is that disenfranchised workers, disenfranchised people in general, can actually generate very significant change. [...] 

Along the way, they had many, many, many successes. They combated prison censorship, they had dangerous work sites closed down completely, they prevented the opening of potentially dangerous new institutions. They fought for, and in many times secured, concessions from prison administrators to respect the rights that they were supposed to be legally guaranteed, and also to enshrine new rights along the way. And they generated unity and solidarity within prisons in ways that actually reduced violence and reduced tension behind bars that led to safer environments in the prison for everyone involved, for themselves as well as for the officers. 

These victories I think are hugely important, and they reveal that these subaltern groups can bring about massive change. It can be easy, especially looking back historically at a story like this, to see it as the story of a failed movement. And I want to make the case that this is not a failed movement. [...]  It's still going on today in different forms, and it's motivated by the same sorts of principles and needs that have persisted for now the better part of the century."
