Post offices in Belleville and Kingston have been hit by rotating strikes. Napanee is still in the clear for now. CUPW, which represents 50,000 postal employees, is demanding improvements in health and safety, gender equality, and service expansions including postal banking. Members have been striking on a rotating basis since Oct. 22, in an effort to put pressure on Canada Post as the two parties try to negotiate new collective agreements for unionized urban and rural workers. Canada Post says the rotating strikes have impacted operations in more than 70 communities across the country, causing backlogs that could delay mail delivery to its customers for several days.
