Which groups were most by the wagner act and the fair labor standards act, passed during the new deal?

Individuals who worked in the private sector (for businesses/corporations) benefited most from the Wagner Act and Fair Labor Standards Act.

In the Wagner Act, workers are granted several different rights they did not have before. This includes the power to join a union without penalty, collectively bargain with their employer over wages, and the ability to strike if needed.

The Fair Labor Standards Act establishes a minimum wage, a scale for overtime pay, a record keeping system to ensure they are getting their correct pay, and child labor laws to protect young children.

As you can see, both of these positively impacted laborers/workers during the era of the New Deal.
