The first Part-Time Faculty Contract was adopted in 2016. We are currently in our second round of contract negotiations and will keep you informed of our progress via email from the PTFA President.
After you agreed to teach your class, your supervisor expanded it by more than 25% of the original capacity (e.g. from 25 students it expanded to 35). You just became eligible for Proportional Pay. Read the Appendix C of the full-time faculty contract (our contract-Article 8-directs us there). Email me if you have any questions.
