350+ CalPortland Drivers Go on Strike Across Northern California Over Contract Dispute
August 10, 2026 // The union said bargaining efforts began on June 8, with the locals calling for simultaneous negotiations on new agreements. However, the Teamsters alleged that CalPortland, instead, scheduled separate bargaining sessions for each local. It claimed that only two bargaining days per month from August to November were allotted. The union argued that the proposed schedule delays negotiations until after the busy summer construction season, when many ready-mix projects have already been completed.
