Roosevelt turned left in 1935-36, building up labor unions through the Wagner Act.

The Wagner Act was the most important labor law in American history and earned the nickname "labor's bill of rights."

The Wagner Act, in particular, legally protected the right of unions to organize.

The Wagner Act of 1935 integrated labor into the nascent system.

This executive order was a breakthrough for public sector workers, who were not protected under the 1935 Wagner Act.

However, the order does not require "good faith negotiations", as the Wagner Act does.

During the 12-year administration of the Wagner Act, unions won victories in over 80 percent of elections.

Also known as the "Wagner Act", the bill provided $500 million for farm relief.

In 1935, Congress passed the Wagner Act to free unions from company domination.

Many of the labor provisions reappeared in the Wagner Act of 1935.
