Today, we’ll continue our discussion of the school life at Harvard. Each year, Harvard students have to pay for the high tuition fees. Fortunately, the University provides students with many employment opportunities. Even before the students come to campus,[23]the Student Employment Office at Harvard will send freshmen some information regarding working at Harvard, given that many students choose to work as soon as they start their new life at Harvard.
    There are both term-time and summer employment opportunities for students. The jobs are available at the Student Employment Jobs Database, from which students can find a variety of jobs, both on-campus and off-campus. In addition to searching for jobs through the jobs database, there are many other ways to find jobs. Some employers will also post their employment information on the website of Student Employment Office.
    Some students work consistently over the course of the year, averaging between eight and twelve hours a week. Other students work periodically and have secured jobs that allow them great flexibility in their work schedules. Students work on and off campus, on the Federal Work Study Program or on Regular payroll. Students may work at a given job as long as they are students at Harvard, and may work more than one job at a time. Students must be paid for hours worked on a weekly basis.
    Undergraduates may not work more than 20 hours per week while enrolled and 40 hours per week when classes are not in session. Graduate students may work up to twenty hours a week. Students are required to report hours worked two ways: electronically or by submitting a paper time card. Students are paid weekly by check or direct deposit. All earnings are subject to federal, state, and local taxes.
    If you are more interested in academic research, you can join in the Faculty Aide Program. The program encourages professors to hire undergraduate research assistants. It provides opportunities for undergraduates to become closely involved in the ongoing research of a Harvard faculty member. Faculty Aide Awards are granted to the faculty member directly. Approved applicants are awarded one $1,500 grant for the academic year or summer term to be used by one student or divided among several.
