OTTAWA—  Canada Post is ramping up operations across the country – welcoming back employees and restarting machines and vehicles. While postal services resume this week, uncertainty and instability in the postal service will continue with the union’s decision to conduct rotating strikes. Shutting down and restarting parts of the integrated national network with rotating strikes will challenge their ability to provide reliable service to customers. As a result, all service guarantees have been suspended. Canada Post says it will take time to clear the trapped volume and manage operational resources, so customers should expect delays in processing and delivery. The Canadian Union of Postal Workers (CUPW) is holding rotating strikes in the following location(s) today: Dawson Creek (B.C.), Fort St John (B.C.), St. Anthony (N.L.), Rotating strikes have ended in:Timmins (Ont.)
