As a result of Obamacare, 22 percent of small businesses reported they are hiring fewer workers or reducing workers' salaries, according to a report from the Mercatus Center.
In addition, 24 percent of large businesses, those with 50 to 199 employees, reported that they were reducing salaries and the number of hires.
Even though roughly half of small businesses said Obamacare did not change their employment practices, 31 percent said they were reducing hours or hiring more part-time workers instead of full-time workers.
Only 11 percent of small businesses said they were increasing salaries and only 10 percent said they were hiring more workers as a result of the Affordable Care Act.
Professor Casey Mulligan of the University of Chicago, author of the study, says the Affordable Care Act has cost businesses roughly 250,000 jobs because of a penalty employers face if they don't provide mandated insurance.
"Thanks to the ACA, hiring the 50th full-time employee effectively costs another $70,000 a year on top of the normal salary and benefits," Mulligan said. "Nationwide, we estimate the ACA-inspired practice of keeping payrolls below 50 has cost roughly 250,000 jobs."
