Under the Affordable Care Act, 30 hours is considered a full-time workweek, at least when you’re determining if a worker is eligible for employer-sponsored health care.

But that might be up for debate. Last week, the U.S. House voted to raise the standard to 40 hours per week. Legislators said the change is needed because businesses were cutting workers’ hours to get under the 30-hour limit.

“Serving our guests is a 24/7 operation, and as such flexibility on scheduling is a critical component,” said Katherine Lugar, president and CEO of the American Hotel & Lodging Association.

“The current 30-hour definition not only undermines that flexibility, but provides an arbitrary threshold that would inevitably lead many small businesses to reduce the number of hours below 30 per week. As a result, the law would inject uncertainty into their team members’ work schedules and in many instances necessitate working extra jobs to make up the income shortfall.”

President Obama has said he’ll veto the bill. It’s not clear how well it will do in the Democrat-controlled Senate. When the House voted on the measure, 18 Democrats crossed party lines to support the 40-hour standard.
