Sexual harassment is a serious problem in universities, and it is receiving increased attention.
Obviously, TAs should be very circumspect in their dealings with students. Many universities sponsor workshops for instructors on avoiding actions that may be interpreted as sexual harassment. In addition to avoiding such actions, TAs must also be very careful when dealing with students who are attracted to them. Although most universities do not have a formal rule prohibiting TAs from dating students, such behavior is clearly not a good idea. Also, TAs who date students will find themselves facing a conflict of interest when assigning grades.
