<prompt> Human: Im a student at a university, and last semester I was teaching part time at the same university. I taught one course, and had a contract for the semester, to be paid a certain prorated over the semester. This contract ended January first of 2018, and I did not return to the position for this semester. Despite this, Im still receiving payment from the University. When I checked the pay stub, it seemed that I was being for the same position as last semester, despite not doing the work. Do I need to bring this up with payroll? I dont plan to spend this money, since I dont want to get into trouble, but Im curious as to what I should do in this situation. Any help is appreciated, thank you!  <response>: Yes. Tell payroll asap. Not doing so will cause a whole lot of extra trouble even if it their fault.
