Word just came in from General Motors that the automaker will be reducing shifts at four different plants that produce its full-size trucks and SUVs in an effort to bring production "in line with market demand". The output slowdown will begin on July 14th at GM's Flint, Janesville and Pontiac assembly plants, which produce the Chevy Heavy-Duty Silverado, Tahoe, Suburban, Silverado and GMC Yukon, Yukon XL and Sierra. The Oshawa truck plant will also be affected starting Sept. 8th. All told, the shift reductions will nix 80,000 full-size pickups and 50,000 full-size SUVs from GM's North American production capacity.

According to GM, both vehicles have lost ground in the market across the industry, with sales of full-size pickups dropping 15-percent and SUVs down 26-percent for the first quarter of 2008. This isn't surprising considering the cost of fuel right now and the subsequent reduced demand for larger vehicles. GM didn't provide specifics about how this would affect workers, only saying that it will "result in lower staffing requirements at all four plants," and that the details "would be worked out over the next several weeks with the UAW and CAW."

Naturally, GM felt the need to brighten up the lackluster announcement by highlighting that car and CUV sales are up. However, it hasn't made a decision to boost output of either type of vehicle in lieu of said increased demand. Check out GM's full press release after the jump.
