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 deal would increase pay by 35% over four years, up from 30% that was offered last month. It also boosts the ratification bonus to $7,000 per worker instead of $6,000. The new offer would not restore a traditional pension plan — a key demand of the 33,000 striking workers — but it would increase the amount of contributions to 401(k) retirement plans that Boeing would match and retain performance bonuses that Boeing wanted to eliminate, the union said.
