Because a 30-hour work week counts as full-time under Obamacare, Fatburger fast-food restaurants had started cutting worker hours below that threshold, CEO Andy Wiederhorn said.

Some Fatburger owners even began “job sharing” with other businesses, teaming up to share a higher number of employees all working fewer hours. Someone could work 25 hours at one Fatburger, 25 at another one with a different franchise owner, and still not be a full-time worker under Obamacare rules.

Many companies at the International Franchise Expo in New York City last month acknowledged they’ve been adopting that slash-and-share method, cutting hours and splitting workers.
