Despite deepening concerns with the economy, most U.S workers feel their jobs are safe for now, a new survey shows.

Of 2,960 employees recently polled by Spherion, a Fort Lauderdale-based staffing firm, only four percent said they believed the economy was getting better, a seven-point drop from September. At the same time, only seven percent said more jobs had been available last month.

Overall, Spherion's monthly employee confidence index dropped to new lows in October.

Despite a sharp increase in U.S unemployment to 6.5 percent last month, nearly three-fourths of the employees surveyed said they weren't worried about losing their jobs in the coming year. Fewer said they expected to be looking for a new job anytime soon, or were confident in their prospects for finding one.

Slightly more workers in October said they felt good about the future of their current employers, the survey found.

Roy Krause, president of Spherion Corporation, blamed the declines in employee confidence on the recent financial turmoil.

"The good news is that the effects of the economic slowdown will not be experienced uniformly, as opportunities still exist for displaced job seekers in certain pockets of the country and in certain industries," Krause said in a statement.

He listed education, accounting, healthcare, government and legal services as recession-proof career options.
