US temporary worker demand is set to fall by 13.7% in 2009, according to the Palmer Forecast.

The industry consulting firm’s findings indicated a 22.2% decline in temporary help for Q3 2009, which actually came in at a 24.5 % decline more than predicted due to higher than expected unemployment figures.

According to the Bureau of Labor Statistics, seasonally adjusted temp jobs fell 23.3% year-over-year in September, up from the 24.5% year-over-year decline in August. Temp jobs, seasonally adjusted, fell slightly, 0.1% sequentially from August.

Palmer says this is an encouraging early sign of rebound and provided a 3.1% boost on a non-seasonally adjusted basis. The 2,000 temp job losses were the lowest rate of loss since October 2007.

The unemployment rate increased to 9.8% in September from 9.7% in August, the highest jobless rate since June 1983.
