They don’t make labor law like they used to, unfortunately. The Supreme Court has steadily been gutting it for 40+ years now, and unionism has unfortunately been subsumed into culture war politics so that even a bare acknowledgement of the imbalances in negotiating power between management and labor is impossible without getting entangled in tribal-political ideology. Which means there’s equally no hope that Congress will reverse any of the erosion of labor rights inflicted by the courts.
