More of America's largest companies will shrink their staffs than will hire in the next six months, according to a quarterly survey from the Business Roundtable, a group of large-company CEOs released Tuesday.

Nineteen percent of the CEOs expect to expand their work forces, while 31 percent predict a decrease in the next six months, the survey found.

That will mean fierce competition for job openings that do exist. Nearly 6.3 unemployed workers, on average, are vying for each opening, government figures released Tuesday show. When the recession began, only 1.7 jobless workers were competing for each opening.

Initial claims for jobless benefits rose by 17,000 to 474,000 in the week ended Dec. 5. The previous week's level was unrevised at 457,000.

Economists surveyed by Dow Jones Newswires expected an increase of 8,000 initial claims.
