The Teamsters said Wednesday they will resume contract negotiations with UPS next week, marking an end to a stalemate that began two weeks ago when both sides walked away from talks while blaming each other. The union credited the picketing and rallies it’s been holding across the country for getting the delivery company back to the negotiating table before the current contract expires on July 31. It said UPS reached out to resume negotiations. And that both sides will set dates soon as to when negations will happen next week. In a prepared statement, the company confirmed negations will resume next week and said it was pleased to go back and “resolve the few remaining open issues.”
