The House of Representatives on Thursday will vote on a bill that would tweak ObamaCare by redefining the full-time workweek from 30 to 40 hours.
The law's employer mandate requires businesses with at least 50 full-time workers to provide health insurance or pay a penalty. Republicans argue that the lower threshold will lead businesses to cut workers' hours in an attempt to skirt the law, though most Democrats believe the proposed tweak is a backdoor attempt to undermine the law's effectiveness.
Called the Save American Workers Act, the bill likely has enough support to clear the House, though it faces an uncertain fate in the Senate.
