Final answer:
The Wagner Act did not create the Federal Mediation and Conciliation Service.
Step-by-step explanation:
The Wagner Act created the Federal Mediation and Conciliation Service.
The Wagner Act, also known as the National Labor Relations Act, was signed into law by President Franklin D. Roosevelt in 1935. It guaranteed workers the right to organize and bargain collectively with their employers and created the National Labor Relations Board (NLRB) to arbitrate disagreements between unions and employers. The Federal Mediation and Conciliation Service (FMCS) was not created by the Wagner Act.
