Can a term in a col­lec­tive bar­gain­ing agree­ment dis­place state law under any cir­cum­stance? How should a court bal­ance the need for con­sis­tent, nation­wide labor stan­dards with con­sti­tu­tion­al con­cerns for pre­serv­ing States’ police pow­ers? In this Con­tri­bu­tion, Micaela Heery (’19) offers an ana­lyt­i­cal frame­work for resolv­ing these pre­emp­tion issues under the Labor Man­age­ment Rela­tions Act. This Con­tri­bu­tion argues that the right legal analy­sis must con­sid­er both whether a claim aris­es inde­pen­dent­ly of the col­lec­tive bar­gain­ing agree­ment and whether pre­emp­tion would be appro­pri­ate giv­en Con­gress’ pow­er over inter­state com­merce and notions of state sovereignty.
