As the newly formed Harvard graduate student union prepares to bargain for the first time, they are tasked with determining who will be part of the bargaining unit. This is particularly challenging because the bargaining unit is complex due to the unpredictable nature of student employment. The union members will be undergraduate employees, graduate students, and research assistants. However, when these students begin and end their teaching varies by program and department need. Job descriptions and titles vary by department as well so it is difficult to determine who should be considered part of the bargaining unit.
