SEOUL, May 21 (Reuters) - Samsung Electronics' shares rose as much as 6.5% in morning trade on Thursday after the tech giant and its South Korean union reached a tentative pay deal, potentially averting a strike that had threatened to hit the economy and undermine global chip supply chains.
The union said the planned 18-day strike by nearly 48,000 members would be suspended while the tentative 11th-hour deal is put to a vote between May 22 and 27.
