With a projected elimination of one out of two production shifts in a car plant in Detroit, General Motors Company have told state officials that it has plans to dismiss almost 1,300 workers beginning March 6, 2017.

Nearly half of the affected employees are temporary workers at Detroit-Hamtramck Assembly, which specifically builds the Chevrolet Volt and Impala, Cadillac CT6 and Buick LaCrosse, according to a letter from the carmaker. The letter was to comply with the federal mass-layoff requirements.
