This website is created in cooperation with Local 143, International Union of Operating Engineers, who operate and maintain the schools of the Chicago Public School system. Local 143 engineers have proudly served the citizens of Chicago and their children for over 85 years. Through this site we hope to bring together school operating personnel from around the globe to share ideas, information, and opinions. We welcome your participation and input.
