US ports strike has started

Tens of thousands of dockworkers have gone on strike indefinitely at ports across much of the US, threatening significant trade and economic disruption ahead of the presidential election and the busy holiday shopping season.

Members of the International Longshoremen’s Association (ILA) walked out on Tuesday at 14 major ports along the east and gulf coasts, halting container traffic from Maine to Texas.

The action marks the first such shutdown in almost 50 years.

President Joe Biden has the power to suspend the strike for 80 days for further negotiations, but the White House has said he is not planning to act.

More than a third of exports and imports could be affected by the strike, hitting US economic growth to the tune of at least $4.5bn each week of the strike, according to Grace Zemmer, an associate US economist at Oxford Economics, though others have estimated the economic hit could be higher.
