Will strikes spell trouble for Biden in a summer of discontent?

It became known as the winter of discontent. After the Labour government tried to freeze wages to stem inflation, Britain was convulsed by labour strikes and disruptions in public services, leading to a fierce political backlash that swept Margaret Thatcher's Conservatives into power.

Forty-five years later, a summer of strikes is disrupting industries from coast to coast in America. Unions have launched or are threatening stoppages that could affect everything from airline travel and parcel deliveries to car manufacturing and film and TV production. They could also disrupt the economic growth that Joe Biden wants to campaign on in 2024.

"It takes him off message because strikes are visual, strikes are hot video, and they're a focal point for media," said John Zogby, an author and pollster. "It becomes lame trying to explain, 'But the numbers are good, but the numbers are good, but the numbers are getting better, when the video just doesn't appear to show it."

The coronavirus pandemic had many aftershocks and labour turmoil may be among them. Hollywood production is shut down as the Writers Guild and the Screen Actors Guild are striking, partially over concerns about streaming revenues as well as artificial intelligence taking away jobs from creative workers. The action has put films and TV shows in limbo and could cost the US economy an estimated $3bn.
