Businesses are holding on to their workers with a far tighter grip than economists expected.

The number of Americans who filed for jobless benefits last week rose by 2,000 to 207,000, a very low level by historical standards.

Economists had forecast claims would rise from the original estimate of 204,000 in the prior week to 210,000.

Jobless benefits are considered a proxy for layoffs and the recent low levels of claims indicate that very few workers are being let go by their employers.

The four-week moving average of claims, which smooths out week-to-week volatility, dropped to 208,750 from 211,250 in the prior week.

The estimate for the number of people who file for benefits after their initial week gets reported with a one week delay. This fell by 1,000 to 1,664,000 in seven day period that ended on September 24. The four-week average of continuing claims fell by to 1,667,500. This level is low enough to suggest that those who have lost their jobs have quickly been finding new positions.
