Obamacare is forcing hundreds of thousands of people into part-time work, according to a new analysis from the bank Goldman Sachs.

In a research note sent out Wednesday, bank economist Alec Phillips concluded that “the evidence suggests that the [Affordable Care Act] has at least modestly elevated involuntary part-time employment.” He wrote that a “few hundred thousand” workers may have had their hours cut or been forced to take part-time jobs because of the law.
