Kelvin

I believe the answer you are looking for is: "a violent or destructive protest." The government would be most likely to become involved in a union protest that is violent or destructive.
This is strictly my opinion but I believe it was a failure. It's original goal was the revitalize the American economy and pull us out of the Great Depression and get American's working again. In this it succeeded to an extent lowering the unemployment rate significantly however it still did not completely work since 15% of the United State's population was still jobless and in poverty. It won't be until WWII and the building of the arms industry as well as army that we will pull ourselves from the Great Depression.
I believe it would be the Jim crow law
The jim crow law is a set of regulations that is aimed to racially segregate the infrastructure that can be used by black and white citizens after the reconstruction.
The laws prohibit blacks citizens to use the same schools, public transportation, restaurants, or hospital as the white citizens.
Since the infrastructures that can be used by black citizens typically lower in quality, it really limited the chance that black people have to advance and prosper in the society.
