At the conclusion of a two-day meeting of the union’s wage committee on Thursday, union members voiced unanimous support for a strike on Oct. 1 if a new contract meeting its demands doesn’t materialize. Harold Daggett, president of the ILA and the union’s chief negotiator, has said he wants a good economic deal for his members, which includes union opposition to port automation and exclusive port contracts.

In a video featuring Daggett played before the energized crowd, he said bargaining in good faith is the only way to get an agreement and threatened a worker slowdown if the Biden administration forces the union workers back to the docks using the Taft-Hartley Act.

A strike by the International Longshoremen’s Association, which moves the trade at the ports along the East Coast, Gulf Coast and Puerto Rico, would impact 43% of all U.S. imports and billions of dollars in trade monthly.
