Boeing has reached a tentative agreement with its union workers, potentially ending a five-week strike that halted aircraft production and threatened layoffs. The deal includes a 35% wage increase over four years, higher 401k contributions, and a $7,000 ratification bonus. It still needs approval from the union members, with a vote scheduled for Wednesday. The strike has cost Boeing an estimated $1 billion a month, and the company recently announced plans to lay off 10% of its workforce.
