If you are receiving a 12-month graduate assistantship, you are expected to be involved in advancing your Ph.D. program on a full-time basis. In addition to University holidays announced for faculty and staff, you are allowed up to two weeks (10 working days) of vacation leave per year. You must obtain the approval of your faculty supervisor or the Director of Graduate Studies if you intend to take any leave of more than a few days. If you wish to have a longer leave (e.g., for the purpose of going overseas), you may accumulate your vacation leaves from previous years.
