Facing withering pressure to stick with the president and block any GOP effort to change Obamacare, 18 Democrats crossed the aisle to join Republicans Thursday in replacing the 30-hour work week with the traditional 40 hours, a major boost to small businesses.

Voting 248-179, the House passed Indiana Republican Rep. Todd Young’s “Save American Workers Act,” which repealed Obamacare’s 30-hour definition of full-time employment.
