On June 25th, you should have received all retroactive pay increases you are owed from the Fall term of 2020 to the Winter term of 2024, provided that you were an active employee in the Winter term of 2024 when the new collective agreement was ratified.
If you were not on contract in the Winter term, you should have recently received an email from someone from Payroll & Records at York asking you to send them your banking information. You must submit that information by September 30th in order to receive the back pay you are owed from 2020-2023. You should receive that back pay by October 25th, 2024, which is the next regular pay date after the deadline.
Important note: This long wait is intended to give the union time to reach out to all former employees to make sure they submit their banking information to receive the pay they are owed. Please help spread the word to your colleagues in this situation who may not be checking their York email!
