The International Brotherhood of Electrical Workers (IBEW), which represents about 750 Canadian National Railway Co. employees, says signal and communications workers have quit their jobs across the country.
Steve Martin of IBEW confirmed in a text that workers were legally on strike from 11 a.m. local time on Saturday.
The IBEW issued a 72-hour strike notice Wednesday morning.
CN did not confirm that the workers had gone on strike, but spokesman Jonathan Abecassis said the company had implemented an “operational contingency plan”, noting that operations were continuing “safely and at normal levels”.
The Montreal-based company says it continues to encourage the union to resolve wage and profit issues through binding arbitration.
CN went on an eight-day strike of more than 3,000 workers represented by Teamsters Canada in November 2019 that halted shipments and disrupted industries across the country.
CN transports more than 300 million tons of goods and consumer goods across the continent each year.
