Employees are allowed a rest period of ten minutes on university time for each four hours of working time. Rest periods should be scheduled as near as possible to the midpoint of the work period with consideration for the work involved. No employee will be required to work more than three hours without a rest period. However, where the nature of the work allows employees to take intermittent rest periods equivalent to ten minutes for each four hours worked, scheduled rest periods are not required. Rest periods are not cumulative and may not be used to shorten workdays. Voluntary attendance at Chapel may be substituted for the morning rest period.
