On picket lines in the Pacific Northwest, strikers said the company’s latest offer wasn't good enough.

Boeing said on Tuesday it has offered additional time and support to the union representing thousands of its striking workers in the U.S. West Coast to vote on its new labor offer, after an earlier Friday deadline was rejected.

Boeing made what it calls a 'best and final offer' to striking union machinists, but the union says it won't vote by Boeing's deadline.
