Any post-contract work (that is, work requested by your supervisor and done after your final grades have been submitted) is separate from your contract and payable at a rate of $67.37/hour. This would include reviewing grades that are being challenged, marking exam that have been deferred, and dealing with cases of plagiarism. This is not an exhaustive list, and more information, including the appropriate form you’ll need to fill out and submit to get paid, is available here. If you are asked to perform this work and are collecting EI or CERB, please let us know.
Once your marks have been submitted (the main list, this does not need to include any deferred exams or extensions based on accommodations), your contract is over and this triggers the beginning of the post-contract period.
