The titles GSI, Reader, Tutor, and Acting Instructor-Graduate Student are covered by a collective bargaining agreement between the University and the United Automobile Workers (UAW). Under the language of the contract, students hired in these titles are referred to as Academic Student Employees (ASEs). See the current UAW Academic Student Unit contract here. GSRs are not covered by the agreement, although university appointment eligibility rules apply to both ASEs and GSRs.
