Boeing’s gambit doesn’t seem to have panned out. That means it is back to the negotiating table with the union.

Amid a union strike over a pay dispute, Boeing has made what it describes as its "best and final offer" to roughly 33,000 striking union machinists, intensifying efforts to end the strike, which has entered its second week.

Boeing on Monday made a new offer to its striking machinists union in hopes of ending a walkout that is costing the cash-strapped jet maker hundreds of millions of dollars a week. The proposal comes 11 days after Boeing’s biggest union rejected a tentative contract and overwhelmingly voted to go on strike.
