Final answer:
Unions experienced gains and setbacks during the New Deal era, while the CIO influenced union strategies with its aggressive tactics and focus on worker rights.
Explanation:
Unions during the New Deal era experienced both gains and setbacks. They gained momentum and support due to labor protections and organized major strikes like the UAW strike at GM. However, setbacks arose post-World War II due to the decline in political backing and a shift towards more moderate strategies by unions.
The Congress of Industrial Organizations (CIO) had a significant impact on union strategies by adopting more aggressive tactics, such as sit-down strikes, and pushing for worker rights and better conditions through collective bargaining. The CIO's actions reshaped the labor movement and influenced the approach of other unions.
