Spherion Corp.'s (NYSE: SFN) employee confidence index edged down in October -- falling one point to a reading of 48.4.

According to the index's survey, the percentage of U.S. workers who believe the economy is getting stronger fell to 23% in October, down four percentage points from September. However, the number of workers reporting confidence in the future of their current employers rose by one percentage point to 64% in October.
