The strike by workers in Washington state, Oregon, and California has halted production of Boeing 737s including the 737 Max, and 767s and 777s. Boeing and the union representing striking machinists have negotiated a new contract proposal that would provide bigger pay raises and bonuses in a bid to end a costly walkout that has crippled production of airplanes for more than a month.The International Association of Machinists and Aerospace Workers said early Saturday that it plans to hold a ratification vote on Wednesday.The union said the Boeing offer would increase pay by 35% over four years, up from 30% that the company offered last month.
