Employees of Boeing's defense department are expected to go on strike starting on Monday.

Due to the rejection of the latest contract proposal by the mechanics of the defense department located in the St. Louis area, Boeing executives faced another strike protest on Monday. The branch of the union representing about 3,200 workers from Missouri and Illinois rejected the aerospace giant's latest four-year contract proposal on Sunday and planned to begin a strike at midnight on Monday, threatening the company's fragile recovery efforts. Over the past week, these mechanics have been working without a contract, during which the company and union representatives have been negotiating on issues such as work schedules and benefits.
