About Us

About CBG

In 1992, Construction Business Group was established and a charter agreement was signed creating our Joint Labor-Management (JLM) organization.

The Joint Labor-Management charter provides for a Board of Trustees consisting of six labor trustees and six management trustees. Both labor and management have equal representation and voting authority. The Board of Trustees meets at least quarterly and is charged with the responsibility of managing the JLM Fund and directing operations.


Our Mission Statement

Our purpose, as a Joint Labor-Management company, is to enhance business opportunities and a quality of life by ensuring fairness, equity and standards of excellence in the construction industry of Wisconsin.
