About Us

Members. Workers. Activists.

Who We Are

First founded in 1973, CUPE 3902 is the largest university-based academic union in Canada. Our local represents workers in a variety of job categories at the University of Toronto, University of St. Michael’s College, and Victoria University.

Who Unit 1 Serves

CUPE 3902 Unit 1 represents over 8,000 members who work tirelessly as Teaching Assistants, Course Instructors, Tutors, Markers, Exam Invigilators, and Chief Presiding Officers. We’re students and academics, who are committed to our communities and students.

OUR TEAMS

The Bargaining Committee brings your Bargaining Platform to the negotiating table with your Employer and works to secure a new Collective Agreement that advances work conditions for all Unit 1 workers.

Lily Ziyue Zhang – Committee Chair
CUPE 3902 First Vice-President

Amidst steep inflation and the rising costs of living, UofT’s proposed cuts to our health benefits send a resounding message: university profits take precedence over our well-being. I organized a petition with our team of Stewards and fellow Members at UTM against these proposed cuts, successfully preventing vision elimination, dental reduction by 12%, and a 35% Health Care Spending Account cut.

I believe that only together can we strive for improved working conditions, wages, and benefits, research excellence, and better education for all! Despite the Employer’s indifference, collective action is our resistance!

Diana M. Barrero (she/her) – Co-Lead Negotiator
Doctor of Philosophy (Ph.D.) program at Department of Curriculum, Teaching, and Learning, specializing in Women and Gender Studies

“I am privileged to be Lúa’s mom. I am also an advocate for public education and am completing my Ph.D. in the Department of Curriculum, Teaching, and Learning, and specializing in Women and Gender Studies.

As a Unit 1 member, I have worked across the three UofT campuses. I have worked as a teaching assistant in the Women and Gender Studies (UTM) and International Development Studies (UTSC) programs, as well as an academic advisor at the OISE Student Success Centre.

I am excited to be part of the bargaining team to defend our past wins and improve our overall working conditions as academic workers.

Previously, I served as the recording secretary and treasurer for CUPE local 3907 (now 3902’s unit 7), as well as 3902’s Chief Returning Officer, and a member of CUPE ON’s Racial Justice Committee.

Tiffany Balducci – Co-Lead Negotiator

I’m excited about working together with the strong membership of CUPE 3902 to create a more transparent and equitable workplace for members of Unit 1. U of T should take care of it’s workers as much as the workers take care of the institution. Together, we will win!

“I am an undergraduate TA in the UTM MCS (Math, Statistics, Computer Science) departmentI TA various computer science courses. I have also been stewarding for my department since last Spring.

I am passionate about bringing an undergraduate perspective to the bargaining table. I am also interested in the way that unions such as CUPE can shape our future with emergent technologies such as AI (artificial intelligence).

I am happy to be on the bargaining team and looking forward to negotiating a better collective agreement for all of us!”

“I’ve worked at UofT for 7 years in the History Department as a TA and Course Instructor. It’s my third round of bargaining working here, but it’s my first time on the bargaining team.
