ADP data shows private companies cut an average of 13,500 jobs per week in the four weeks ending November 8, signaling faster layoffs.
The latest ADP Pulse contrasts with October, when private firms added 42,000 jobs.
U.S. companies eliminated more than 150,000 jobs in October, the highest October total since 2003.
Economists are relying more on ADP reports because federal labor data has been delayed by the recent 43 day government shutdown.
The Bureau of Labor Statistics will fold some missing October data into the November report and will not release an October unemployment rate.
