Picketing
Picketing is a form of labor protest in which workers engaged in a dispute assemble outside an employer's place of business, typically carrying signs to advertise their grievances, inform the public, and discourage patronage or the entry of non-striking personnel.[1] This tactic serves as a means of exerting economic pressure on the employer by disrupting normal operations through peaceful persuasion, though it has historically involved varying degrees of confrontation.[2] Under the U.S. National Labor Relations Act, primary picketing—directed at the disputing employer—is generally lawful when conducted peacefully, but it is circumscribed by prohibitions on violence, blocking access, or extending to secondary targets like neutral businesses, which could constitute unlawful boycotts.[3] Prior to the 1930s, courts routinely issued injunctions against picketing, viewing it as a restraint of trade or conspiracy, until the Norris-LaGuardia Act limited such judicial interventions and facilitated its use during the expansion of union organizing.[2] Empirical analysis reveals picketing's potential effectiveness in curtailing business activity, with a recent study of grocery strikes finding it caused substantial reductions in store foot traffic, thereby amplifying the strike's leverage.[4] Notable controversies surrounding picketing stem from its coercive elements, including mass assemblies that impeded access and escalated to violence in some disputes, prompting reforms like those in the 1947 Taft-Hartley Act to curb secondary activities and ensure public order.[5] While instrumental in advancing worker demands in key historical confrontations, such as early 20th-century industrial strikes, picketing's role has diminished amid declining union density and legal safeguards for employers, reflecting a balance between expression rights and economic continuity.[2]
