A special pay request may be submitted by institutions of higher education and related boards:

(1) When a unique configuration of work requires skills, duties, or working conditions beyond those typically required of comparable positions;

(2) To alleviate employment problems such as recruitment and/or retention;

(3) When failure to grant special pay could result in recruitment and/or retention problems which would seriously jeopardize the effective operation of the institution; or

(4) To prevent salary inversion or compression problems with other classes in the same or related series which have been granted special pay.
