A lot of the challenges come out of the specifics of the laws surrounding unions. They were written in a much rougher era, where corporations and unions were very much in direct opposition. If we could re-write those laws, we could open the door to much more cooperative relationships between unions that the current laws do not allow. Unfortunately, there's no sign of the republican and democratic parties getting together to make a grand bargain on the laws, so we're stuck with them as they are today.
