Contract negotiations between Boeing and its striking union broke down Tuesday, with the company pulling back its latest contract proposal.

“Further negotiations do not make sense at this point,” Boeing Commercial Airlines Chief Stephanie Pope said in a statement to employees. “Unfortunately, the union did not seriously consider our proposals.”

The company said it revoked its “best and final” offer from September on Tuesday. That offer included a 30% pay raise and a performance bonus. According to the union, that proposal was nonnegotiated and membership overwhelmingly rejected the proposal late last month.

The IAM rejected Boeing’s accusations, arguing that the company wouldn’t consider meeting the union’s demands.

“They refused to propose any wage increases, vacation/sick leave accrual, progression, ratification bonus or the [401(k) match],” the union said in a statement. “They would also not reinstate the defined benefit pension.”
