Yes, there are two exceptions allowed by the policy: Business purpose and Academic purpose. Complete details of who is eligible and how to request each type are in the policy.
The Business purpose exception is intended for requests which are pre-planned and will be ongoing over the course of a semester. However, there may be unplanned, emergency circumstances or work of a very short duration (maximum of two pay periods) for which an exception may also need to be requested. In these situations, rather than following the procedure outlined in the policy, requesting departments may instead submit an Exception Request for Student Employee Work Hours form.
