The Service Employees International Union (SEIU) Illinois Council joins more than 150,000 members who power a wide variety of industries across the region.  The Council is widely regarded as an ardent champion of working people; representing members in child care, property services, the public sector and health care related industries—fields that contribute to the overall prosperity of state and local economies. (Learn more about SEIU’s healthcare workerspublic service workers, and property service workers.) The Council exists to protect and bolster a standard of living for members and their families by bargaining for good labor contracts and bringing the benefits of SEIU membership to non-union employees. We advocate to affirm the dignity of each worker, the services they provide and to promote fairness in the workplace.

Our work is guided by a simple vision: Give each worker a voice in decisions that affect them.

SEIU, the largest union in the nation, was founded in Chicago nearly 100 years ago. Today, our locals carry on a proud tradition of advocacy that stretches from the Illinois General Assembly to the U.S. Congress.  Our members are located across Illinois, Indiana, Southern Wisconsin, Ohio, Michigan, Kansas and in St. Louis, Missouri.

Our mission is accomplished through several interrelated activities:

  • Voter registration
  • Political action fundraising
  • Lobbying
  • Member and public education
  • Coalition building
  • Member mobilization
  • Political activists’ training
  • ‘Get Out the Vote’ efforts
