SEOUL, March 18 (Reuters) - Samsung Electronics' 005930.KS unionised workers in South Korea voted on Wednesday to authorise a strike, deepening a labour dispute over bonuses and raising the risk of production disruptions at the world's biggest memory chipmaker.
A total of 93% of its 66,019 workers who cast ballots approved the strike plan, the union said.
If the workers fail to agree a deal, they plan to strike for 18 days from May 21, the union has said.
