(1) Further employment at any college of an individual who has been employed at that college on a part-time basis for four consecutive semesters in a position designated as being in the Professional Services Negotiating Unit shall be on the basis of a term appointment. In computing consecutive semesters of part-time service for the purposes of appointment or reappointment under this subdivision, periods of leave of absence at partial salary or without salary shall not be included, but shall not be deemed an interruption of otherwise consecutive service. An individual who has been granted term appointment but for whom classroom enrollment is inadequate shall have no entitlement to salary, benefits, or any other rights or privileges.

(2) In the event the service of such an individual is interrupted for a period of four consecutive semesters or more, the chief administrative officer of the college may grant the employee any type of appointment as in the chief administrative officer's judgment is appropriate.
