§25.1 Members of the academic staff designated as department chairpersons may be paid a stipend for duties and responsibilities of that function subject to the following limitations:

a. The stipend may not exceed 10 percent of basic annual salary when paid for duties as department chairperson during the term of professional obligation. Payment of such stipend precludes extra service during the term of professional obligation.

b. A further stipend, not to exceed 10 percent of basic annual salary, may be paid to faculty having academic year professional obligations for duties as department chairperson which are performed solely during the summer after completion of the academic year professional obligation. Payment of such stipend precludes other summer employment within the University.

c. A combination of stipends under paragraphs (a) and (b) shall not exceed 20 percent of basic annual salary.

d. The stipend shall not be added to basic annual salary. The stipend shall be removed upon termination of the employee's designation as department chairperson, whose salary thereafter shall be at the rate due as a regular member of the academic staff.

§25.2 Members of the academic staff designated as department chairperson who do not receive a stipend for duties and responsibilities of that function may perform extra service and may be employed during the summer under the usual rules and procedures applicable to such employment.

§25.3 The provisions of Section 25.1 pertaining to stipends shall not apply to employees in the medical and dental schools of University medical centers or health sciences centers whose budget certificate titles are "Professor and Department Chairman"; provided, however, the provisions of such Section pertaining to extra service and summer employment shall apply.
