We value training and have a growing apprenticeship facility, providing apprenticeship entry level training and journeymen upgrade training to all members.

We understand that organizing increases our clout at the bargaining table and work closely with our surrounding sister locals and other crafts. We are a strong community based organization and provide support to our area charities. We have established a scholarship fund that helps to support the dependents of Local 318’s members to give them a helping hand with college tuition.
