Passage of the Taft–Hartley Act and Override of the Veto

The passage of the Taft-Hartley Labor-Relations Act and the override of Harry S. Truman’s veto became a sharp test of his labor policy and his authority in the face of a Republican-controlled Congress. Truman rejected the bill as an attack on working people, but his veto could not hold: within days, Congress enacted the measure over his opposition, with more House Democrats voting against him than for him.

Causes and Legislative Stakes

In June 1947, Congress passed the Taft-Hartley Labor-Relations Act by large majorities. Its provisions curtailed union power in several ways: it outlawed the closed shop, made unions liable for breach of contract, prohibited union political contributions, required financial reports, and required union leaders to take a non-Communist oath. The legislation thus touched both labor’s organization and its political activity, placing Truman’s response at the intersection of his policy judgment and the Democratic Party’s relationship with labor.

Truman’s Veto

After two weeks of deliberation, Truman vetoed the bill on Friday, June 20, calling it an attack on the workingman. His decision ran against the advice of nearly his entire United States Cabinet: all but Lewis Schwellenbach and Bob Hannegan urged him to sign, including John Snyder, his closest friend in the Cabinet. The disagreement made the veto more than a straightforward clash with Congress; Truman rejected counsel from within his own administration as well.

The pressure inside the administration was not all in one direction. Clark Clifford urged Truman to move left on most issues and saw the bill as an opportunity to take a stand. Thousands of letters arriving at the White House also favored a veto. Truman believed the measure was bad legislation, while the political consequences mattered too: a veto, he knew, could help bring labor back into Democratic politics. As Margaret Truman Daniel later observed, her father’s response to his presidential conscience did not mean he had stopped being a politician; the two impulses could coexist.

Override and Immediate Consequences

Congress voted to override the veto only days later. The result was an unmistakable legislative defeat: in the House, more Democrats voted against Truman than supported him. The episode therefore exposed a limit of presidential opposition. Truman could state his judgment publicly and use the veto, but those acts could not substitute for the votes needed to sustain it.

Political Significance

The veto joined policy conviction to party calculation without making either the whole explanation. Truman genuinely opposed the bill, and he also understood that opposing it could help restore labor’s place in the Democratic coalition. The override, meanwhile, showed that even a decisive presidential stand could fail when congressional majorities were prepared to act against him. The conflict captures a recurring difficulty of his presidency: he did not simply abandon a position when Congress resisted, but persistence did not guarantee that Congress would yield.
