Businesses are preparing for a strike by dockworkers on the East and Gulf Coasts, which could begin Oct. 1 if negotiations don’t yield a new contract.

Even a short strike at East and Gulf Coast ports could disrupt U.S. supply chains until 2025, according to one expert.

The clock is ticking down to a potential port strike on the East Coast and Gulf of Mexico, where consumers could face product shortages and price spikes just ahead of the holiday season.

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 said Monday it has raised its offer to the International Association of Machinists union in an effort to end the strike by 33,000 union members that has now entered its 11th day.

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.
