Required length of work term. 1  Work terms must consist of full-time employment (35-40 hours per week) for 16 weeks (matching the length of a four-month academic term). Work terms generally start and end on the dates published in Quest, under Important Dates.
As defined by the United States government, the standard workweek consists of five eight-hour days for a total of 40 hours per week. The average workday also includes a 30-minute lunch; a full-time employeeâs pay for this period is up to the discretion of his or her employer. If the employeeâs schedule consists of a 4-day work week, the shifts will typically last ten hours. The work hours attached to full-time jobs are not absolute; a full-time employee may work more or less than the common 40-hour week.
