If layoffs occur within an operational area and the academic staff members involved do the same or similar work, fixed-term appointees shall be laid off before probationary appointees and probationary appointees shall be laid off before indefinite appointees. Seniority shall determine the order of layoff within each type of appointment. Exceptions to the order of layoff as defined in this section shall be recommended to the Chancellor by the dean or division head only to maintain specific expertise or to maintain established objectives within the operational area defined in UWM 104.05. The Chancellor shall solicit advice of the Academic Staff Committee prior to the decision on exceptions. Such advice shall be given within 20 working days of receipt of the Chancellor’s request.
