On December 27, 2018, the National Labor Relations Board enforced a decades old policy that a union’s unqualified threat to picket a neutral employer at a “common situs” a/k/a a construction site is a violation of the National Labor Relations Act.

Background

The case involved area standards picketing by the IBEW of a project owned by the Las Vegas Convention and Visitors Authority (LVCVA). The IBEW sent a letter to various affiliated unions who were working on the project advising them of its intent to engage in area standards picketing at the project directed to the merit shop electrical subcontractor performing work there. The IBEW also sent a copy of the letter to the LVCVA.
