Samsung Electronics Co.'s unionized workers voted to approve a wage agreement that includes a substantial bonus package for chip workers, the union said Wednesday, easing concerns over potential disruptions to the global supply chain. In the six-day vote, 73.7 percent of the 62,616 members of the tech giant's two largest unions approved the tentative deal. The agreement was finalized after a majority of eligible voters took part in the vote and a majority voted in favor of the proposal. Later
