50,000 members of the Canadian Union of Postal Workers (CUPW) have been on rotating strike since 22 October. The Trudeau Liberal government has tabled so-called “back-to-work” legislation, that will make this work stoppage illegal. Increasingly, the right to strike in Canada is not worth the paper it is written on. As soon as a strike becomes effective, it is declared illegal. However, the postal workers are angry and there is a real opportunity that they will defy the legislation. Solidarity is urgently needed to let the CUPW workers know they are not alone, and that workers in Canada and internationally support their fight.
