Graduate teaching assistants work for universities. Generally, they are given a cubicle in an office, which they can use for their studies and their assistantship work. Teaching assistants will also work in classrooms. Graduate teaching assistants spend a lot of time interacting with students, professors, and other assistants. Most graduate teaching assistants work part-time, in addition to completing full-time graduate studies. Many universities do not allow graduate teaching assistants to obtain additional employment outside of their assistantship. Graduate assistant offices are often some of the least funded places in a university. However, they do promote a sense of community between graduate students because of their openness and proximity to each other.
