The union and Obama are also at odds on the matter of whether Obamacare will cause businesses to cut their employees’ weekly hours below 30 to avoid the law’s mandates.

“I would say broadly that if you look at the economic data, the suggestion that the ACA is reducing full-time employment is belied by the facts,” White House press secretary Jay Carney told reporters last year.

The union disagrees. “Close to 400 employers announced plans to cut workers’ hours back to less than 30 to stay below the 50-worker full-time threshold, more than a year in advance of the employer mandate,” the report says. The law creates that “perverse incentive” because a Health and Human Services regulation defines “full-time” status as 30 hours of work weekly.

The report even complains about the exemption for congressional staffers that Sen. David Vitter, R-La., has tried to eliminate.
