Take a moment to review the revised procedural rules that dictate the process of the National Joint Adjustment Board for the Sheet Metal Industry.

Parties wishing to appear before the NJAB should familiarize themselves with the Procedural Rules. Revised rules for 2026, featuring changes in the submission process are now available.
The Standard Form of Union Agreement for the Sheet Metal Industry provides that grievances, as well as disputes over the failure to negotiate the renewal of a collective bargaining agreement, shall be heard under such procedures as may be established by the National Joint Adjustment Board.
In circumstances where the National Joint Adjustment Board has revised its Procedural Rules, the revised procedures have been applied to any dispute submitted to the National Joint Adjustment Board on or after the effective date of those revisions.
