Negotiators for General Motors Co and the United Auto Workers are scheduled to restart bargaining Monday to resolve a strike that shut down the automaker’s highly profitable U.S. operations. The UAW on Sunday launched the first company-wide strike at GM in 12 years, saying negotiations toward a new national agreement covering about 48,000 hourly workers had hit an impasse. Workers took to picket lines outside GM factories, waving signs declaring “UAW On Strike.” During the walkout, UAW members will get $250 a week from the union’s strike fund.
