Teaching assistants at both Concordia University and Queen’s University are hitting the picket lines this week. Concordia’s Research and Education Workers Union—which represents more than 2,000 teaching and research assistants—launched an indefinite strike last week after reaching an impasse in negotiations with the university. Key issues on the table include wages and job security. At Concordia, the Public Service Alliance of Canada Local 901 are beginning their strike today. The union—which represents approximately 2,000 teaching assistants, teaching fellows, and research assistants—is citing pay, mental health, and child-care as core concerns. Queen’s issued a statement assuring its community that the campus will remain open and that academic activities will continue.
