Thousands of dockworkers at ports along the East and Gulf Coasts went on strike in search of higher pay and better job security in the face of automation.

The strike was expected to involve 25,000 workers, according to USMX, and close 14 ports: Baltimore; Boston; Charleston, South Carolina; Jacksonville, Florida; Miami; Houston; Mobile, Alabama; New Orleans; New York/New Jersey; Norfolk, Virginia; Philadelphia; Savannah, Georgia; Tampa, Florida; and Wilmington, Delaware.

“USMX brought on this strike when they decided to hold firm to foreign owned Ocean Carriers earning billion-dollar profits at United States ports, but not compensate the American ILA longshore workers who perform the labor that brings them their wealth,” ILA President Harold Daggett said in a statement posted on social media. “We are prepared to fight as long as necessary, to stay out on strike for whatever period of time it takes, to get the wages and protections against automation our ILA members deserve.”
