Welcome to the Amalgamated Transit Union Local 308.
ATU Local 308, chartered on December 1, 1902, represents the dedicated men and women who keep Chicago’s transit system moving. Our mission is to strengthen public transit while improving the wages, benefits, and working conditions of our members, and to uphold the Constitution and By‑Laws that protect their rights.
As the exclusive bargaining agent for Chicago Transit Authority employees amongst our 27 classifications. Local 308 is led by elected officers, executive board members, and assistants, all who serve 3-year terms. We are also supported by a full‑time office manager and in‑house attorney.
For more than a century, thousands of members have fought to secure the protections and progress we benefit from today. Through collective bargaining and solidarity, Local 308 members have helped shape the modern transit system and the quality of life it supports.
Our history is a reminder that the work we do today will shape the future for the next generation of transit workers—just as past members shaped it for us.
