As for the NRLB, they aren't particularly powerful anyway. They don't even have they authority to execute their own decisions, everything has to be signed off on by a federal judge and is subject to appeal. Which is probably the reason nobody has bothered to fill any of the vacancies on it for the last 4 years.
That being said, I've seen a lot of crazy things in the last couple months with Obama and the democrats. So it wouldn't surprise me if they tried anything at this point.
