WASHINGTON, DC - JANUARY 07: Sen. Joe Donnelly (D-IN) (L) and Sen. Susan Collins (R-ME) hold a news conference to announce their reintroduction of the "The Forty Hours is Full Time Act," in the U.S. Capitol Visitors Center January 7, 2015 in Washington, DC. President Barack Obama threatened to veto the House version of the 40-hour legislation, which would allow employers to avoid providing health coverage to workers who put in less than 40 hours a week -- up from the law's current 30-hour threshold.
