“When government requires firms to offer benefits, employers will generally prefer to hire part-time workers, who will not be subject to the penalty. Even though the Affordable Care Act counts part-time workers by aggregating their hours to determine the size of a firm, part-time workers are not subject to the $2,000 penalty. Hence, there will be fewer opportunities open for full-time work. Many workers who prefer to work full-time will have an even harder time finding jobs.
In January 2012 over 8 million people were working part-time because they could not find full-time jobs. The new health care law would exacerbate this problem.”
