Obamacare stipulates that large employers don't have to provide health insurance to those working fewer than 30 hours a week.
As a result, critics say, employers have increasingly cut worker hours to stay within the limit.
Fox Business' Stuart Varney noted Monday the latest jobs report showed 278,000 people were pushed involuntarily into part-time work when they wanted full-time work.
"In large part, that's because Obamacare's coming down the pike," Varney said.
The squeeze isn't happening only in the United States.
In Japan, employers have been limiting workers' hours to avoid paying health insurance for them for decades, Money Morning Chief Investment Strategist Keith Fitz-Gerald said on Fox Business' "Varney & Co."
