Kellogg workers ratify a revised contract after being on strike since October.

About 1,400 striking Kellogg workers have ratified a new contract, their union said Tuesday, ending a strike that began in early October and affected four of the company’s U.S. cereal plants.

“Our striking members at Kellogg’s ready-to-eat cereal production facilities courageously stood their ground and sacrificed so much in order to achieve a fair contract,” Anthony Shelton, the president of the workers’ union, the Bakery, Confectionery, Tobacco Workers and Grain Millers International Union, said in a statement. “This agreement makes gains and does not include any concessions.”
