In September, the US economy added 142,000 jobs while the unemployment rate held firm at 5.1%.

August's job gains were also revised lower — to 136,000 from 173,000 initially — and data on wage growth disappointed with wages coming in flat for September while they rose less than expected against the same month last year.

Rosenberg noted, however, that when you take into account the decline in weekly hours worked, the job gains turn into outright losses.

And they are ugly.

Here's Rosenberg (with our emphasis):

Adding insult to injury and revealing an even softer underbelly to this report was the contraction in the workweek to 34.5 hours from 34.6 hours in August, which is effectively equivalent to an added 348,000 job losses.

So take the headline number, tack on the downward revisions and the loss of labour input from the decline in the workweek, and the "real" payroll number was -265,000. You read that right.

Additionally, Rosenberg notes that the August-September payroll gains of 136,000 and 142,000 back-t0-back now make the softest two-month stretch since December 2013 and January 2014, when the "polar vortex" dragged down the economy.
