Our History

Our Past Makes Our Future


Union organizers come to Flint, Michigan to organize the auto plants.

February 11, 1937 - The Great Sit Down Strike in Flint at the Fisher Body #1 and #2 plants ends with the first contract between General Motors and the UAW.

January 4, 1939 - Local 598, representing Fisher 2 workers, is granted its charter. Up until now, all plants in the Flint area have been represented by Local 156.


February 1, 1942 - Due to World War II, the Fisher 2 plant is temporarily shut down and the workers are transferred to other Flint area plants. A special arrangement is made with the International Union to keep our charter active as long as at least 12 members pay union dues. As the war continues, Local 598 is chosen to represent many of the small parts plants that have sprung up as a result of the war.

Early 1945 - The war ended and General Motors announces that it will build a new plant on Van Slyke Road that will house both Fisher Body 2 and Chevrolet Assembly facilities.

February 11, 1948 - As a result of a suggestion from Bert Christensen, a member of the Education Committee, Local 598 members begin what has become a UAW tradition, honoring those who sat down in 1936-37 (the Great Sit-Down strike) by wearing white shirts into work on the day that the first UAW-GM agreement was reached. Brother Chistensen felt that by wearing white shirts (traditionally worn by management) we would show that we were as good as white collar workers and also when management walked up and down the factory floor and saw everyone wearing white shirts , it would demonstrate the strength and unity of UAW workers, as well as the dignity of all UAW working men and women.


January 1950 - A one acre plot of land on Van Slyke Road is purchased for $750.00 so we can finally have a union hall of our own.

Summer 1954 - A second shift is added and many people are hired into the plant through 1955.


Sam Duncan was elected to his first full term as President (he would go on to serve eight consecutive terms.) The size of our membership passed the 2,000 mark for the first time ever.

November 1965 - A 30 day strike is called over job standards. The resulting time-study agreement marked the first time that both management and union used the time-study procedure to settle job disputes.

June 22, 1969 - Groundbreaking ceremonies were held and construction of a new union hall was begun. Shortly after that management informed our bargaining committee that it would no longer abide by the Job Standard or Comparison agreements (that we won in 1965) for the 1970 model year. A strike vote was taken and approved. As the strike deadline neared, no progress was reported in negotiation of over 1,200 Paragraph 78?s and over 500 penalties.

September 24, 1969 - At 4:45 p.m., 15 minutes after the second shift had begun, Local 598 Fisher Body workers took on GM in the longest strike by the UAW in GM history.


February 6, 1970 - After 136 days on strike, Fisher Body workers ratified a new agreement.

March 20, 1970 - GM announced that all Fisher Body 2 workers would be permanently laid off and that side of the plant would be turned over to Chevrolet for the building of light trucks. The future of our workers and our Local was uncertain, and it seemed like an obvious retaliation for the 1969 strike.

June 11, 1970 - The International Union announced that Local 598 would represent the workers at the Truck Plant and the seniority lists of the two plants (which had been represented by Local 659 and Local 598) would be merged as one.

June 24, 1970 - Fisher Body 2 goes out of existence.

March 1971 - Our new Union Hall is completed.
