Service Periods and Pay Periods

As defined in Article IX, Section 4(c) of the University of Illinois Statutes, minimum salaries for various faculty ranks shall be determined by the Board of Trustees.  The minimum for eleven months’ service shall be approximately two-ninths greater than the minimum for the academic year (nine months service).  Additionally, the General Rules, Article IV, Section 1 (h), require all employees rendering service on a twelve-month basis (eleven months service with one month vacation) shall be compensated in twelve equal monthly installments except when an appointment effective date or termination date results in a partial month service as defined by the Monthly Pay Date below.  General Rules also require employees, with the exception of assistants, rendering services during the academic year (nine months) to be compensated in twelve equal monthly installments or on a pro rata basis for shorter periods.  Standard Service Definitions are as follows:
