WASHINGTON (AP) — Nearly half the 70 employees at a Ford dealership in Clarksville, Ind., have been out sick at some point in the past month. It didn't have to be that way, the boss says.

"If people had stayed home in the first place, a lot of times that spread wouldn't have happened," says Marty Book, a vice president at Carriage Ford. "But people really want to get out and do their jobs, and sometimes that's a detriment."

The flu season that has struck early and hard across the U.S. is putting businesses and employees alike in a bind. In this shaky economy, many Americans are reluctant to call in sick, something that can backfire for their employers.
