Teamsters Dispute with UPS - Yahoo United Parcel Service Inc. (UPS), the world's largest package delivery company, stated that the National Mediation Board (NMB) has dismissed a bid of Teamsters Local 2727 union to go on a strike against the company in the next 30 days. Teamsters Local 2727 represents approximately 1,400 airline mechanics, who work for United Parcel Service. Teamsters asked NMB to declare the ongoing negotiations for the new contract to be stalemate, failing which the strike will not be called off. However, if NMB declares the proposed deadlock, the company and Teamsters will commence a new round of negotiations. The union started bargaining with United Parcel Service for more than three years, but did not reach any settlement since 2006.
