Legislative findings and declaration.The General Assembly finds that a union, union members, sympathizers, and an employer’s employees have a right to communicate their dispute with a primary employer to the public by picketing the primary employer wherever they happen to be. The picketing may take place not only at the employer’s main facility, but at job sites as well. The General Assembly recognizes that peaceful primary picketing of any type is explicitly permitted by statute pursuant to the National Labor Relations Act, 29 U.S.C. § 151 et seq., and the Labor Management Relations Act, 29 U.S.C. § 141 et seq., including the right to engage in other concerted activities for the purpose of collective bargaining or other mutual aid or protection as provided in 29 U.S.C. § 157 et seq.
