Summary
Question: Does the NLRA preempt the state's authority to enjoin a marine engineer union's picketing where the marine engineers are defined as supervisors and not employees? Conclusion: No. In a 9-0 decision Justice John M. Harlan wrote for the majority. While a state may not regulate conduct arguably protected or prohibited by the NLRA, the Supreme Court found that Hanna's engineers were supervisors, not employees, and were not covered under the Act. The NLRA did not preempt Wisconsin's authority in this situation. The Court reversed the lower court decision and remanded the case to the Supreme Court of Wisconsin.
