As a part-time faculty member (teaching 6 hours or less per week), you are technically not unionized, and therefore, do not have the protections of our collective agreement. Similarly, you do not have the protections under the CCBA, and therefore, are not obliged to follow Work to Rule.
While we appreciate your solidarity, risking your job is not what we want. There will be other ways that you can continue to support your colleagues, but for now, ensure you fulfill your job duties are per usual.
