REUTERS/Rebecca Cook/File Photo Acquire Licensing RightsWASHINGTON, Sept 12 (Reuters) - Talks between the Detroit Three automakers and United Auto Workers union are nearing a Thursday night deadline to reach a deal on a new contract before a potential walkout by 146,000 U.S. autoworkers. Coordinated strikes would mark the first-ever simultaneous labor stoppage at all three Detroit automakers and one of the largest U.S. industrial labor actions in recent years. LAST DAYS BEFORE DEADLINEThe UAW on Friday had rejected revised offers from Stellantis, General Motors (GM.N) and Ford Motor (F.N). GM said Tuesday CEO Mary Barra decided not to attend Business Roundtable meetings in Washington on Wednesday and Thursday because of the labor talks. "She changed her plans in order to stay close to the labor negotiations process," GM spokesperson Jeannine Ginivan said.
