Teamsters union serves CN Rail with 72-hour strike notice

The notice says that the union does not believe any of the ongoing issues between the railway and the Teamsters to be "insurmountable"

The Teamsters union has served Canadian National Railway (CN) with a 72-hour strike notice, hours after saying it was taking down picket lines and workers were returning to the job.

"Please find this letter as official notice to the company of our intention to withdraw the services of our combined membership of approximately 6,500 members," reads the notice sent to CN on Friday morning by the Teamsters Canada Rail Conference.

The notice says that the union does not believe any of the ongoing issues between the railway and the Teamsters to be "insurmountable" and that it remains open to negotiating with the company in order to prevent any "further work stoppage."
