US ports longshoremen’s strike (East and Gulf coasts)

There used to be a labor movement in the US - but it’s been virtually nonexistent for decades.
One of the reasons, amongst many others, is that the overall U.S. economy has become far-less reliant on heavy industry, steel, manufacturing, automobile industry to.a certain extent, rubber and packaging plants like we were from mid-19th century until late 60's/1970's with digitalization, automation and Internet and now AI-based tech companies have taken far greater precadent.

Plus, unlike 60-65 years ago, U.S. is more of a consumer-based economy where production of goods, not heavy industrialized companies are what makes up 85-90% of our overall gross GDP. Thats why former thriving industrial towns like Cleveland, Pittsburgh, especially Detroit with its auto industry, Buffalo, Erie, Pennsylvania, mining towns in the Southwest have struggled or had to reinvent themselves over the past 50 years. Also, a lot of these former industries had strong labor representation, but when the supply and demand "calculus" changed or economic priorities altered dramatically post-WWII and after OPEC oil shocks of the mid/late 70's, many labor unions not just in U.S, but also U.K. with its TUC, and older, aging British infrastructure, industrial grid, had a hard time keeping up because those sectors weren't as vital or important anymore like they were, lets say a century ago. As a result, many labor unions struggled to keep up.
