The threat of port strikes across North America continues to send jitters across already stressed supply chains.

Canada’s Industrial Relations Board (CIRB) over the weekend ruled that a planned 72-hour strike against DP World in Canada went against the country’s labour code, narrowly averting a three-day shutdown this week.

The ILWU Ship & Dock Foremen Local 514 had given formal notice to its employer on Friday for action to start on Monday leading to a frantic weekend of negotiations and discussions to avoid a strike.

ILWU 514, which represents close to 600 workers, has been negotiating since November 2022 and is asking for wage increases and retirement benefits, among other demands.
