The number of part-time workers in jobs for economic reasons shot up by 468,000, apart from the 458,000 that left the workforce altogether.  Slack work or business conditions accounted for 181,000 of these jobs, while another 77,000 could only find part-time work.

Analysts at Goldman Sachs have noticed this trend for some time, and put the blame on Obamacare.

“The evidence suggests that the [Affordable Care Act] has at least modestly elevated involuntary part-time employment,” Goldman Sachs economist Alec Philips wrote in a research note published on Wednesday. Obamacare had the greatest impact on industries that traditionally do not offer strong health insurance coverage, such as retail stores and the hospitality industry. Phillips noted that these have the highest levels of involuntary part-time workers, and believes that the ACA has forced “a few hundred thousand” to take cuts in hours or accept part-time work as a result.
