NJAB & Dispute Resolution


The National Joint Adjustment Board for the Sheet Metal Industry (NJAB) serves as an arbitration board to resolve grievance and contract renewal disputes after they have been processed through the local level.

The operation of the NJAB is to promote, improve and maintain peaceful labor-management relations by creating this medium for adjudication of locally deadlocked disputes and to discourage strikes, lockouts and work stoppages in the entire sheet metal industry. The board is comprised of labor and management panelists from the International Association of Sheet Metal, Air, Rail and Transportation Workers (SMART) and SMACNA, respectively.

Questions regarding the NJAB should be directed to the NJAB administrator, Maggie Powers.
