There just isn't enough demand for the Saturn Outlook, GMC Acadia and Buick Enclave. So General Motors will not add a planned third assembly shift to its Lansing Delta Township plant, where the three are made.

"Before you go to holiday break, it's not a pleasant feeling," UAW Local 602 President Doug Rademacher told News 10.

The third assembly shift at Lansing Delta Township was supposed to have started already, but earlier this year, GM decided to push back the start of the shift.

"It was pretty clear at that point it was the sales," plant worker Michael Osborn said.

That's why the announcement is not a suprise for the 28-year GM veteran. But it is a disappointment.

"We all wanted to see it do a little better," Osborn said.

While there is not enough demand to support three shifts, the market is calling for more cars than two regular shifts can produce, GM spokeswoman Heidi Magyar said.

The decision could end work for 480 temporary employees. They were added to get the new plant up the speed and union leaders say the temporary workers knew the work could dry up at any time.

But some regular workers could feel the impact too. The plant already has a third shift on the paint and body lines. Those jobs could be eliminated as the plant moves toward a two-shift system.

Rademacher says there's no word on when that could happen.

"At this time, everyone is going to stay employed and we're going to continue on until a date is announced," he said.

Even if a date is announced and those third shift paint and body jobs disappear, Rademacher says he sees signs of hope. He thinks the lack of demand is more about the economy than the vehicles Delta makes.

"We will continue to produce these world-class vehicles," Rademacher said. "Hopefully, the market will turn, people will want them, the demand goes up, they'll need our workers."

But for now it appears, they don't.
