Boeing ( BA) said a federal mediator has asked for negotiations to resume to end a 45-day machinists' union strike. The talks between the aerospace company and the International Association of Machinists and Aerospace Workers are scheduled to resume Thursday. The union represents about 27,000 workers. "We've remained in frequent contact with the federal mediator, and we look forward to resuming discussions with the IAM," Boeing said. "We want to resolve the strike in a way that rewards our employees while we retain our ability to compete in a dynamic and challenging market." Talks to end the strike broke down last week. The strike, which began on Sept. 6, has centered largely on job security. "We hope this marks a major step forward to resolve this strike," the union said in a statement. "The union will continue to do everything possible to bargain a contract that addresses the concerns our members have identified." Boeing's commercial aircraft assembly plants have been shut down throughout the strike, costing the company about $100 million or more a day in deferred revenue, according to the Associated Press.
