To prove asbestos exposure, you need to show where you worked, when, what you did, and which asbestos products were present. Employment records answer the first three questions, and they point investigators toward the fourth. Because mesothelioma appears decades after exposure, these records often matter more than memory.
At Throneberry Law Group, rebuilding a client’s work history is where every case begins. Michael Throneberry has done this for about two decades, and he lost his own father-in-law to mesothelioma. We know which agencies, unions, and pension plans still hold records after an employer is long gone, and we use them to support mesothelioma litigation and trust claims.
What Can Employment Records Show
Employment records can establish the basic facts of a work history that a company cannot easily dispute. Personnel files, payroll records, job descriptions, union dispatch records, pension documents, worksite assignments, and Social Security earnings statements each fill in part of the picture. Together they can establish:
- Employer and job title: Who employed you and what position you held, such as pipefitter, machinist, or maintenance worker.
- Dates of employment: Start and end dates that show how long you were at a site.
- Work locations: The specific plant, shipyard, refinery, or building where you worked.
- Job duties: Descriptions of tasks that could have disturbed asbestos materials.
- Full career history: Records from several jobs that let us investigate exposure at more than one workplace.
Public health researchers rely on the same information. The National Institute for Occupational Safety and Health explains that detailed occupation and industry data is how researchers learn whether illnesses run higher in certain jobs, and notes that work is often overlooked as a source of health problems.
How Do Records Connect to Asbestos Products
An employment record does not prove asbestos exposure by itself. It proves you were at a place during a period, and from there we investigate what was in the building. A record showing that you were an insulator at a power plant from 1968 to 1979 tells us which boilers, turbines, and pipe systems to research and which manufacturers supplied them.
Other evidence then strengthens the connection. Company purchasing records, product catalogs, prior testimony from the same site, and coworker accounts can confirm that specific asbestos materials were used while you were there. Our research on asbestos companies often matches a worksite to several manufacturers at once.
Where Do Old Employment Records Come From
Many clients assume their records are gone because the employer closed. In our experience that is rarely the whole story.
Sources That Outlast Employers
Unions keep dispatch and membership records for decades. Pension administrators keep service histories. The Social Security Administration can provide an itemized earnings statement that lists every employer who paid you. Successor companies, state licensing boards, and workers’ compensation files can add more.
Why Short Jobs Still Count
A job you held for six months in 1974 can matter as much as a career position. Short-term work at a shipyard, refinery, or construction site frequently involved the heaviest exposure. Our occupational exposure pages describe the trades where this was common.
Why a Complete Work History Matters
A complete work history can reveal exposure sources that would otherwise be missed, and more sources usually mean more responsible parties. Each additional defendant or trust can add to the compensation available in a mesothelioma lawsuit or trust claim.
We review employment records alongside medical records, witness accounts, and product evidence to build a clear account of how, when, and where exposure happened. That account is what the companies have to answer.
