Waukegan Plant List of Red Slip Pneumoconiosis Cases, with Dates Diagnosed and Dates Informed (1972)

A five-page list headed "Information on 'Red Slip' Cases, Waukegan Plant," dated May 1972 and copied to Dr. T. H. Davison, R. F. Winkworth, H. M. Jackson and the medical department. It numbers 174 workers at J-M's Waukegan, Illinois, plant who had been given "red slips" for dust disease, with each man's clock number, department, diagnosis (pneumoconiosis, mixed pneumoconiosis or asbestosis, by stage), the date the disease was diagnosed, from 1945 to 1971, and the date he was informed. Three mesothelioma cases from 1971 are listed separately at the end.

What it shows

The "informed" column records when each worker was told. In the early entries it often falls years after the diagnosis (a case diagnosed in October 1950 was informed in January 1955); by 1969 to 1971 the gap is mostly weeks or months. The list belongs with J-M's internal correspondence on the red slip system: R. C. Smith's 1963 memo, with which the same list was filed, Dr. Davison's 1963 letter on untold red slip cases, and C. L. Hite's 1971 letter on the red slip cases and the union.

In Johns-Manville's chronology

Johns-Manville's own chronology of what the company knew describes this document as follows:

This is a list of Waukegan plant employees, clock numbers, department numbers, diagnoses, date of diagnosis, and date informed for 173 pneumoconiosis and asbestosis cases for which "red slips" were given at the Waukegan plant. Three mesothelioma cases are also listed separately. In most instances, the time lag between the date of diagnosis and the date informed is one or two years or more. The time period of diagnosis dates ranges from 1945 to 1971.
