full_context: Document 1: Inauguration of Herbert Hoover: The inauguration of Herbert Hoover as the 31st President of the United States was held on Monday, March 4, 1929, at the east portico of the United States Capitol in Washington, D.C.. The inauguration marked the commencement of the only four-year term of Herbert Hoover as President and of Charles Curtis as Vice President. Chief Justice and former President William H. Taft administered the presidential oath of office to Hoover. This was the first time a Presidential inauguration to be recorded by sound newsreels. It was also the second (and most recent) time that a former president administered the oath of office to a new President.
Document 2: Warren G. Harding: Warren Gamaliel Harding (November 2, 1865 – August 2, 1923) was the 29th President of the United States, serving from March 4, 1921, until his death in 1923. At the time of his death, he was one of the most popular presidents, but the subsequent exposure of scandals that took place under his administration, such as Teapot Dome, eroded his popular regard, as did revelations of an affair by Nan Britton, one of his mistresses. In historical rankings of the U.S. presidents, Harding is often rated among the worst.
Document 3: Railway Labor Act: The Railway Labor Act is a United States federal law on US labor law that governs labor relations in the railroad and airline industries. The Act, passed in 1926 and amended in 1934 and 1936, seeks to substitute bargaining, arbitration and mediation for strikes as a means of resolving labor disputes. Its provisions were originally enforced under the Board of Mediation, but were later enforced under a National Mediation Board.
Document 4: Herbert Hoover: Herbert Clark Hoover (August 10, 1874October 20, 1964) was an American engineer, businessman, and politician who served as the 31st President of the United States from 1929 to 1933 during the Great Depression. A Republican, as Secretary of Commerce in the 1920s he introduced Progressive Era themes of efficiency in the business community and provided government support for standardization, efficiency and international trade. As president from 1929 to 1933, his ambitious programs were overwhelmed by the Great Depression, which seemed to get worse every year despite the increasingly large-scale interventions he made in the economy. He was defeated in a landslide in 1932 by Democrat Franklin D. Roosevelt, and spent the rest of his life as a conservative denouncing big government, liberalism and federal intervention in economic affairs, as Democrats repeatedly used his Depression record to attack conservatism and justify more regulation of the economy.

Arthur: Chester Alan Arthur (October 5, 1829 – November 18, 1886) was an American attorney and politician who served as the 21st President of the United States (1881–85); he succeeded James A. Garfield upon the latter's assassination. At the outset, Arthur struggled to overcome a slightly negative reputation, which stemmed from his early career in politics as part of New York's Republican political machine. He succeeded by embracing the cause of civil service reform. His advocacy for, and subsequent enforcement of, the Pendleton Civil Service Reform Act was the centerpiece of his administration.

Document 7: National Labor Relations Act of 1935: The National Labor Relations Act of 1935 (49 Stat. 449) (also known as the Wagner Act after New York Senator Robert F. Wagner) is a foundational statute of United States labor law which guarantees basic rights of private sector employees to organize into trade unions, engage in collective bargaining for better terms and conditions at work, and take collective action including strike if necessary. The act also created the National Labor Relations Board, which conducts elections that can require employers to engage in collective bargaining with labor unions (also known as trade unions). The Act does not apply to workers who are covered by the Railway Labor Act, agricultural employees, domestic employees, supervisors, federal, state or local government workers, independent contractors and some close relatives of individual employers.
Document 8: 1919 Actors' Equity Association strike: The 1919 Actors' Equity Association (AEA or “Equity”) strike officially spanned from August 7, 1919 to September 6, 1919. The AEA had, only a few weeks prior, become affiliated with the AFL and called the strike against the Producing Managers’ Association on August 7. Before the strike, many actors were required to give hundreds of hours of free rehearsal time, pay for their own travel and costume expenses, and could be fired immediately for not playing their roles to their managers' satisfaction. Between August 7 and September 6, hundreds of actors walked out of theaters predominantly in New York City and Chicago. As the strike gained support, other laborers in the industry walked out with them, including musicians and stagehands. During negotiations on September 6, 1919, the managers gave the actors all of their demands after losing millions of dollars.
Document 9: Railroad Labor Board: The Railroad Labor Board (RLB) was an institution established in the United States of America by the Transportation Act of 1920.

The Board was terminated on May 20, 1926 when President Calvin Coolidge signed a new Railway Labor Act into law.

The strike lasted from June 29 to August 2, 1928, and severely affected the transportation of people and goods across South India. The Madras government and the South Indian Railway Company responded with a crackdown. Most of the leaders of the strike were arrested and recognition to the union was withdrawn.
Document 14: Railway Express Agency Building: The Railway Express Agency Building was a historic building located at 1804 Western Avenue in Mattoon, Illinois. The building was constructed in 1918 to serve as the Mattoon office of the Railway Express Agency. The Railway Express Agency provided rail express shipping services to Mattoon's citizens, allowing them to ship money and packages along Mattoon's two major railways, the Illinois Central Railroad and Cleveland, Cincinnati, Chicago and St. Louis (Big Four). The agency formed in 1917, when the federal government ordered that all existing express services consolidate into a single service; this measure ensured consistent shipping of goods during World War I. The agency shipped goods to and from Mattoon until 1964, when the Big Four went bankrupt; the building served as a freight depot until 1971.
Document 15: Calvin Coolidge: John Calvin Coolidge Jr. ( ; July 4, 1872 – January 5, 1933) was the 30th President of the United States (1923–29). A Republican lawyer from Vermont, Coolidge worked his way up the ladder of Massachusetts state politics, eventually becoming governor of that state. His response to the Boston Police Strike of 1919 thrust him into the national spotlight and gave him a reputation as a man of decisive action. Soon after, he was elected as the 29th vice president in 1920 and succeeded to the presidency upon the sudden death of Warren G. Harding in 1923. Elected in his own right in 1924, he gained a reputation as a small-government conservative, and also as a man who said very little, although having a rather dry sense of humor.
