Working on the late shift

Once the academic year begins we work one day a week from 1 PM to 8 PM. The librarian on the late shift must be at the reference desk from 5 PM - 8 PM. The first hour is usually busy since the day students are still here while the evening students are arriving and often visit the library before class. From 6 PM - 8 PM there are few transactions at the desk since students are in class until 9 PM. The main advantage of working late is avoiding the rush hour crowds on the trains. The disadvantage is getting home late and waking up early the next morning.
