The midterm elections of 1946 had an unfavorable impact on organized labor as they marked a shift in the balance of power in Congress towards conservative anti-labor forces. The Republicans gained control of both the House and the Senate, leading to the passage of anti-labor legislation such as the Taft-Hartley Act of 1947, which weakened unions' power and put restrictions on their ability to strike. This marked a setback for organized labor and hindered their ability to protect workers' rights and improve working conditions.
