Trade and labor unions are a vital part of Chicago’s history. Despite its slow decline in recent years, Chicago remains one of the most unionized cities in the U.S. The 5 largest labor unions continue to fight not just for the benefit of union members, but non-union members alike.
Illinois Labor Union Statistics
In 2023, Illinois had 708,000 union members and 47,000 wage and salary workers who were represented by a union or covered by a contract but were not union members themselves. The unionization rate in Chicago is 12.8%, which is notably higher than the national rate of 10%.
Other Illinois labor union statistics include:
- 15% men
- 11% women
- 19% Black workers
- 13% White workers
- 9% Hispanic workers
- 14% military veterans
Although the approval rating for unions is at an all-time high, union member rates in Illinois and Chicago have steadily decreased in recent years for several reasons such as fewer manufacturing jobs, faster overall employment growth compared to union membership, and more low-union density careers.
