Obama's fourth veto: Protecting workers

As threatened, President Obama vetoed a congressional attempt to block the National Labor Relations Board's new rules to streamline and modernize union representation election rules.

It's the second veto of the year for Obama, and the fourth of his presidency. More vetoes are sure to come: the White House has issued 17 specific veto threats on bills working their way through Congress, and several others still being drafted in committee.

With Congress out of session for its Easter recess, Obama issued a "pocket veto" of the resolution. But as he's done twice before, he also sent the Senate a veto notice "to leave no doubt that the resolution is being vetoed."

The new NLRB rules make it harder for bosses to stall elections by withholding information and filing frivolous lawsuits, tactics bosses often use to buy time to intimidate workers away from the union.
