The Wall Street Journal reported Monday that Pillar Hotels & Resorts, which includes 5,500 part-time workers on its payroll, is among those hiring more part-time workers.
"The tendency is to say, 'Let me fill this position with a 40-hour-a-week employee.' I think we have to think different," said Chief Executive Officer Chris Russell.
CKE Restaurants is owned by Apollo Management, an equity firm. In turn, CKE runs Carl's Jr. and Hardee's restaurant chains. In late summer, the firm began hiring part time workers to replace full time workers who retired, the Journal reported.
Erin Shields Britt, a spokeswoman for the Department of Health and Human Services said studies have shown that the profile of the U.S. labor market would not change significantly due to the healthcare law.

"This law will decrease costs, strengthen our businesses and make it easier for employers to provide coverage to their workers," she said in a statement.
