Who is MCO

Michigan Corrections Organization, Service Employees International Union, Local 526M, proudly represents 6,000 Corrections Officers and Forensic Security Assistants working inside Michigan’s prisons and the Center for Forensic Psychiatry. MCO also represents Absconder Recovery Unit investigators and other Michigan Department of Corrections employees.

MCO isn’t your typical labor union. We proudly hold the highest membership density of any state of Michigan employee union. Members own the union and are engaged on the things that matter most to them. Our leaders (who are members themselves) and staff listen to members intently, and that input guides the union as we work to transform corrections. We take our messages beyond just state politics and are leading a nation-wide campaign to raise the professional profile of corrections officers. We engage our members through initiatives like our Officer Dignity initiative, Military Members Committee and many others. We design and deliver world-class trainings and believe in creating opportunities for members to become directly involved.
