CalPortland Ready-Mix Drivers Begin Unfair Labor Practice Strike

Over 350 ready-mix concrete drivers at CalPortland in Northern California have begun an unfair labor practice strike, alleging the company has engaged in unfair labor practices. The drivers, represented by Teamsters Locals 853, 665, 315, and 150, ceased working on Monday.

The strike, which commenced in the Oakland area, is reportedly aimed directly at the company's bargaining conduct. Union representatives stated the drivers are seeking fair negotiations with CalPortland. Specific details regarding the drivers' demands or the ongoing bargaining process have not been publicly disclosed.

CalPortland is a major supplier of construction materials and services on the U.S. West Coast. The work stoppage could impact construction timelines for projects relying on the company's ready-mix concrete supply in the region.

The company has not yet issued a public statement regarding the strike. Union officials confirmed the strike's initiation and indicated they will continue efforts until a resolution is reached through fair bargaining.
