Did the new deal NRA work and how?

The NRA you are taking about here is the (National Recovery Administration), not the (National Rifle Association).

The (National Recovery Administration), did not work well because it did not provide enough protection for labor to bargain with management, and it failed to enforce the restraints on wages, hours, and working conditions, plus the fact that the Supreme Court unanimously ruled it unconstitutional in 1935, although its provisions would be included in later legislation.
