With no deal on the table, thousands of dockworkers began day one of a strike on Tuesday.

Union workers from International Longshoremen’s Association Local 1814 in New York City are some of the 45,000 workers unhappy with negotiations between them and the U.S. Maritime Alliance.

Strikes are happening at ports along the East and Gulf coasts.

Workers want a 77% pay increase over six years, and restrictions and contracts on machines coming in that could replace workers.

“You cannot tell working class people that they should deliver for the city, but then you don’t want to deliver for them,” Mayor Eric Adams said.

Adams joined dockworkers at the Red Hook Container Terminal on Tuesday. This as some suppliers have concerns about the long-term impacts of the strike.

“It’s just not compatible with my view of the world that there could be a port strike for two months as the holidays approach, but I guess until we see that deal come through that option remains out there,” said Josh Kaye, senior vice president of operations and technology of Frederick Wildman and Sons.

Kaye said they have thousands of cases of wine stuck out in the Atlantic until the ports reopen. They’re weighing the possibility of shipping items west through the Panama Canal.

“If in eight weeks there’s still a strike, then it will look genius that you routed it through the west, but if you start routing containers and paying thousands of dollars per container to reroute them, then the strike gets resolved, then you look bad on that side,” Kaye said.

U.S. Maritime Alliance offered a 50% increase over six years.

In a statement a representative said, in part, “We look forward to hearing from the Union about how we can return to the table and actually bargain, which is the only way to reach a resolution.”

The strike could lead to shortages, though experts say consumers won’t notice a difference for a few weeks.
