Unionized workers at Canadian Pacific Railway have delivered a 72-hour strike notice.
The company issued a news release Saturday saying that negotiations are continuing with the Teamsters Canada Rail Conference, who represent 5,000 Canadian Pacific employees.
The news release says the workers, who include conductors, trainmen, yardmen, locomotive engineers and rail traffic controllers, can walk off the job at 12:01 a.m. May 23.
The workers have been negotiating with CP since October to try to reach a new contract — the last one expired in January.
The union says CP is demanding major concessions on pensions, work rules and wages.
The company says if there is a work stoppage, it will "proceed with a safe and structured shut down of its train operations in Canada."
“The offer on pension aligns with the industry and allows the railway to remain competitive as we invest in strategic infrastructure upgrades along our network,” CP chief operations officer Mike Franczak said in a statement.
