The USX National-Duquesne Works records offer an unusual richness of documentation on the workforce at a major steel producer in operation for over a century. Inactive pension files reflect job and wage progressions of native and immigrant workers, as far back as the 1870s. Statistical breakdowns of mill accidents according to occupation, nationality, department, severity, cause, and part of the body affected are present for the 1912-1918 period, while individual case files as well as periodical statistical reports of injuries commence in 1930. An extensive set of grievance records documents shop floor relations from the 1930s to 1980s. Also of interest are the more than 12,000 employee National Defense cards from the 1940s and a smaller set for the 1950s. Approximately 30% of the early 1940s card series contain thumbnail photographs of the employees. Ledgers dating from 1941 to 1966 recorded citizenship verification information and address listings. Management and clerical personnel are also documented in the collection in various ways. There are binders which contain photographs of supervisory personnel at National Works (1950s) and Duquesne Works (1980), and employment records for foremen and other salaried workers. Videotape safety programs, safety posters and numerous primarily safety-related 35 mm slides, document the company approach to accident prevention, while minutes of company-union safety meetings, along with grievance records, show the points of contention and correspondence in the approach to plant safety. Corporate public relations films are also of interest. A microfilmed set of company filmed employment records provides additional demographic information on employees, while some other employment related files, including some pension files, which were water damaged when accessioned, have been microfilmed by the University Library System for the Archives. Finally, company subject files on strikes and work stoppages from the post-union period are significant in their detail, while some manuscript narratives from pre-union period strikes at National Tube (1891, 1904, and 1919) are colored by their author's management perspective.
