An undergraduate going to school on a university scholarship isn't doing work (such as laboratory research or being a TA or teaching intro classes); these graduate students are. When the undergrads at my alma mater were TAs or research assistants or whatever, they were absolutely considered part-time employees of the university, in addition to their student status. If they were doing full time work, forty hours of work a week, they would have been considered full time employees. Why should those employees not be subject to the same employment protections afforded to the non-student employees?
