Auto parts maker Autoliv is laying off about 7% of its Utah work force -- or 250 workers -- because of the downturn in the automotive market. A spokeswoman says the company has been forced to make cuts to its production, development and technical staff. Autoliv, which makes air bags and seat belts, employs about 37,500 people around the world. Since last July, it has laid off 5,900 workers. The company employs about 3,300 employees in Utah.
