“Prosperity for all” cannot occur when millions are impacted by a criminal justice system that imprisons hundreds of thousands of people—in the name of privitization—violates a public trust to enrich the private prison industry. According to the Population Reference Bureau, the United States has the largest prison population in the world and the highest rate of incarceration (number of prisoners per 100,000 persons). This reality of mass incarceration brings irrevocable harm to working people, as families with loved ones who are either behind bars or who cannot find decent employment upon release, and as taxpayers who see their tax dollars put into jails instead of schools, affordable housing, better transportation and a cleaner environment. The reality of states subcontracting what should be a public system to the for-profit prison industry incentives profits over justice and leads to overcrowding and inhumane conditions. This Action Session will begin the process of developing a labor movement analysis of mass incarceration that outlines how union members are affected by mass incarceration outside the workplace as their families and neighborhoods are impacted, and inside the workplace as their unions are involved in the criminal justice system or perform work that can address the causes and consequences of mass incarceration.
