Unionised workers at South Korea's Daewoo Motor and GM Daewoo Automotive & Technology Co voted on Thursday to launch a strike over wages and other benefits, Reuters reported. "Over 78% of 7,957 union members at Daewoo and GM Daewoo voted for a strike," a spokesman at GM Daewoo told the news agency which noted that unlisted GM Daewoo is South Korea's third-largest car maker and was created after General Motors and partners took a majority stake in some of the assets of Daewoo Motor last year.
