New Website! — cupe3903.org

After a lot of hard work and effort, our new website is available at cupe3903.org! We are soft launching it and intend to gradually migrate over material from 3903.cupe.ca to the newly updated website. There will be a transitional period where both websites are updated to some extent, after which, 3903.cupe.ca will be archived.

For all the latest CUPE 3903 news, meetings and events, information about who we are, what we fight for, and more, your new source is cupe3903.org! Special thanks to our Staff, Maija Duncan, for all of her efforts. We hope you love the new site!

For any questions about the new website, email the Communications Officer, Mackenzie Edwards, at cupe3903comms@gmail.com
