Angela Cornell, a Cornell Law School labor law professor, called it "another decision that undermines the capacity of unions to function." MORE STRIKESThe ruling comes at a time of increasing strikes called by U.S. labor unions. Some experts pointed out that the ruling largely preserved the existing legal scaffolding for deciding labor law preemption cases of this kind. The Supreme Court, with its 6-3 conservative majority, has dealt setbacks to organized labor in key cases in recent years. Brudney said Thursday's ruling "was not comparable to that broader trendline" of decisions weakening labor unions.
