Court decisions citing the 2 opinions that defined “concerted activities” — 1,326 in all, by decade. Counts are citations to the defining cases as a whole, not verified uses of the term. The dip in the most recent years is a data-coverage gap, not a real trend — our corpus holds fewer opinions from the latest years.

Section 7 of the Labor Relations Act took this conspiracy weapon away from the employer in employment relations which affect interstate commerce. No longer can any state, as to relations within reach of the Act, treat otherwise lawful activities to aid unionization as an illegal conspiracy merely because they are undertaken by many persons acting in concert. But because legal conduct may not be made illegal by concert, it does not mean that otherwise illegal action is made legal by concert.
