Rob Ashton, president of the ILWU Canada, said in a statement that it did not believe the recommendations had the ability to protect union jobs. His group estimated that the first strike would cause an average 6-8 weeks of supply chain disruption before conditions would return to normal. The National Association of Chemical Distributors told CNBC some chemical companies are expected supply chain congestion until October as a result of the strike. Critical chemicals that go into food, cleaning, water purification, and personal care, among many others, flow through the West Coast ports of Canada and down to the United States.
