Canadian National is at risk of losing its signal and communication people if neither side can agree to avert a strike.
If there is not a settlement by Saturday workers will walk off the job. A strike happened back in March, and a work stoppage lasted more than 72 hours.
Canadian National said it has worked with the union of the signal and communication workers in good faith and will continue to do so. Wages and benefits continue to be the sticking point, and CN said it has offered to work out the differences through binding arbitration. The Class 1 said it was ready to execute its operational contingency plan if a strike does happen Saturday morning, and that plan would be active for as long as it was required.
