This page gives details about workloads and Time Use Guidelines (TUGs) for Teaching Assistants (TAs), Tutor Markers (TMs), Sessional Instructors (SIs), and English Language and Culture (ELC) / Interpretation and Translation Program (ITP) Instructors.

We recommend all members log your hours and have built tools to help you do that

Workload and Base Units for TAs/TMs


For each appointment you should receive a contract which outlines your start and end date, rate of pay, and the type of appointment. This contract is a very important part of your employment relationship and you should ensure that you receive one from your department.

Time Use Guidelines (TUGs)

A Time Use Guideline (TUG) is a form that outlines the expected breakdown of hours for a TA/TM appointment. The amount of hours on the TUG must not exceed the amount of hours available for the appointment.

Workload Reviews

Every TA/TM must receive a workload review during the course of their appointment as a way of checking in. It is the responsibility of the Employer to ensure that workload reviews are completed. If you have not received a workload review, please contact us.

Work after the semester

A TA/TM contract has a specified start and end date. After the end of the contract, any work a TA/TM is asked to perform must be compensated at an hourly rate. Contracts typically end after the last day of classes, but this can vary depending on the department and the semester. If you have been asked to work after the end of your contract, please contact us.

Contact Hours for Sessional Instructors

Since Sessional Instructors do not have hours of work in their contracts, pay is calculated based on the amount of time spent in lectures, tutorials, and seminars (known as “contact hours”). See Article XIV.D.2 of our Collective Agreement for more information.

If a course is marked “conditional upon enrollment” it may be cancelled after being assigned to a Sessional Instructor. If this happens, the Sessional is eligible for .75 contact hours worth of pay, or 1 contact hour if the course is cancelled in the first week of classes. See Article XVII for more information.

Work after the semester

Sessional Instructors who work outside the term of their appointment are eligible for additional pay as per article XIV.D.3 (Sessional instructors / Compensation). The rate of pay for such work is at the GTA 2 rate, calculated hourly.

Contact Hours for ELC/ITP Instructors

The Collective Agreement outlines two types of hours for ELC/ITP Instructors: Contact Hours, or “instructional hours scheduled by the University,” and non-Contact hours, or “[w]ork hours not scheduled by the University, that constitute the balance of the standard full-time work week” (L Article V.A.1&2, p.105).

The number of hours scheduled by the University determines the contact hour workload, and another unscheduled 1 hour  and 20 minutes per contact hour makes up the balance of the standard work week. For the full-time maximum of fifteen (15) hours, this results in a maximum total of thirty-five (35) hours per week (it’s pro-rated for those scheduled for fewer than the maximum).

The Collective Agreement defines overtime as “time worked in excess of seventeen (17) contact hours in any given week,” “paid at one and a half (1.5) times the instructor’s regular contact hour rate for hours worked” (L ArticleV.7.b&c, p. 106).

Special Assignments

Other “[s]pecial assignments,” “shall be part of the scheduled workload in lieu of contact hours” (L Article V.8, p.106).
