Things are even worse than you might think for part time workers

You might know how many people are getting part-time jobs because of Obamacare.  But part-time workers have tried to make things up by getting multiple part-time jobs.  The problem is that with so many part-time workers for firms their work schedules have gotten very erratic.  Those erratic schedules  make it very difficult for them to hold down those multiple part-time jobs.  From NPR:

. . . The ranks of people working part time because they can't find full-time jobs have roughly doubled since the summer of 2007, from about 4.3 million to 8.2 million. . . .
employers also are worried about the financial impact of the Affordable Care Act, she says. That federal law soon will require employers with 50 or more full-time workers to offer affordable insurance to employees working 30 or more hours per week. 

Not hiring full-time workers right now reflects "strategic thinking on the part of businesses that fear they are going to face higher costs," Mathur says. 

Such concerns were reflected in survey results released Tuesday by Sageworks, a company that analyzes the financial results of private companies. The poll of 300 accountants who work with private companies found that 2 out of 3 say concern about the new law isdampening hiring plans.
