Jurisdictional strike is a worker’s strike resulting from a dispute between the members of different unions over work assignments. The Taft-Hartley amendments to the National Labor Relations Act empowered the National Labor Relations Board to resolve such jurisdictional disputes. The Act also authorized the General Counsel of the NLRB to seek an injunction barring such strikes.
The following is an example of a state statute (California)defining the term:
Cal Lab Code § 1118. Jurisdictional strike
As used in this chapter, "jurisdictional strike" means a concerted refusal to perform work for an employer or any other concerted interference with an employer's operation or business, arising out of a controversy between two or more labor organizations as to which of them has or should have the exclusive right to bargain collectively with an employer on behalf of his employees or any of them, or arising out of a controversy between two or more labor organizations as to which of them has or should have the exclusive right to have its members perform work for an employer.
