Series 3: Interpretation of Rules, 1911-1935

This series consists of a general index and thirteen volumes of Rulings and Interpretations on Shop Craft Rules, as were agreed on in 1935. In these volumes, the work rules and agreements between the ICRR and all non-operating shop-craft employees and their unions are filed along with correspondence, interpretations, rule applications, any minutes of meetings held regarding that rule, any subsequent interpretations, as well as charts and graphs containing quantitative data regarding the work rules. The unions involved in these agreements include: International Association of Machinists; International Brotherhood of Blacksmiths; International Brotherhood of Boilermakers; International Brotherhood of Electrical Workers; International Association of Railway Carmen; International Brotherhood of Sheetmetal Workers; and Brotherhood of Railway and Steamship Clerks. Many of the documents used in these volumes are duplicates of records found in the Subject Files, though these are marked "Reader Copy."
