Answer:
The upsurge of strikes during that time period.
Step-by-step explanation:
The Act was approved in 1947 against President Truman's veto by the 80th Congress, the first to be elected after World War II ended, with strong Republican/Southern Democratic majorities taking control of both chambers. Its intention and outcome were to repeal labor-friendly laws passed during the New Deal era (1933–1966). It resembled the "Right-to-work" legislation that were implemented in southern and midwestern states quite a bit. It made it more difficult for a union to become a bargaining unit and increased management's ability to obtain antilabor injunctions with waiting periods and other tools. It also outlawed the closed shop and some types of strikes and boycotts.
Its namesake, Senator Robert A. Taft, was descended from a well-known political family; his father served as President before becoming an Associate Justice of the US Supreme Court and ultimately its Chief Justice. He was a brilliant scholar as well as a very elitist and conservative isolationist before World War II. In the Republican primary of 1952, he was Dwight Eisenhower's main rival.
