The Globe and Mail reports in its Wednesday edition that a proposal by Canada Post to create a new class of employees who would work flexible, part-time hours is provoking the ire of the Canadian Union of Postal Workers and is adding to difficulties over negotiations for a collective agreement. The Globe's Vanmala Subramaniam writes that more than 55,000 Canada Post workers have been on strike since Friday. Canada Post wants to make its parcel delivery services more competitive, after years of losing billions of dollars from dwindling letter mail. The Crown corporation wants to add new part-time jobs to accommodate seven-days-a-week delivery. Canada Post is proposing the creation of two new employee classifications called "part-time flex" and "weekend part-time flex," which would effectively be permanent part-time positions working different shifts to deliver parcels. The union has long been unhappy over the growing number of temporary and part-time employees within the postal service, calling it "gigification." Canada Post's Jon Hamilton said that the corporation needed an employment model that leaned more heavily on part-time work rather than full-time jobs to compete with delivery giants such as Amazon.
