Teamsters Local 453 and Potomac Farms Dairy have signed a new contract after a nine-week strike that kept milk from area schools, according to the Cumberland Times-News in Maryland.

At the time of the strike, the union represented 55 workers at the dairy in Cumberland and others working in Oakland, Moorefield, W.Va., and Culpeper and Broadway, Va. Overall, Local 453 represents more than 500 workers at about 35 employers in the four-state region.

At issue was Potomac Farms Dairy’s desire to end contributions to workers’ pension plans. It is unclear if the ratified contract is the same as the final offer made by the company in June. Details of the agreement have not been released.

The Galliker Dairy Co. of Johnstown, Pa., owns the Potomac Farms Dairy operation.
