Local 81 organizes the Heat & Frost Insulators across Eastern Iowa and the Iowa-Illinois Quad Cities region — historically a major center of agricultural-equipment manufacturing (John Deere), aluminum and steel work, and the Mississippi River industrial corridor.

Notable workplaces in Local 81 territory
Through the asbestos era (roughly 1920s through early 1980s), Local 81 members were dispatched to facilities throughout the jurisdiction — many of which are now documented in federal NESHAP filings, state regulatory databases, and public asbestos litigation records. Major workplaces in the Local 81 historical territory included:
John Deere plants (Davenport Works, Harvester Works, Engine Works, Foundry) · Rock Island Arsenal · Alcoa Davenport · MidAmerican Energy Walter Scott and Louisa generating stations · Quaker Oats Cedar Rapids · ADM Cedar Rapids · Cargill Cedar Rapids · the major Quad Cities hospitals (Genesis Medical, UnityPoint Trinity) · Mercy Medical Center Cedar Rapids · St. Luke’s Cedar Rapids.
These are categories of workplace, not an exhaustive list. Local 81 dispatch records held by the Local’s business office contain the specific job-by-job assignments for individual members. For an active or retired member pursuing an asbestos claim, those dispatch records are typically the foundational evidence establishing which jobsites the member was on and when.
Why this Local matters for asbestos claims
Local 81’s cross-state jurisdiction means members can have viable claims under either Iowa or Illinois law. Iowa’s 2-year SOL versus Illinois’s 2-year SOL with broader venue options — an experienced attorney can analyze where a specific case best fits. The John Deere manufacturing complex was one of the most extensively insulated agricultural-equipment facilities in the country.
