Position Management wants to work very closely with supervisors and managers. But remember, their work is with the classifications of positions and not people. Upgrades are a way to reward good performance. Merit raises are used for this purpose. Position Management reviews the position not the person.
All positions deserve upgrades.
If the basic job function has not changed but only the tools used to accomplish the function, an upgrade is not necessarily merited. The skill of the library manager in writing a position description determines whether or not the position is upgraded. Position Management is looking at changes in the position not for magic phrases. Look at the entire organization in order to be equitable in reviewing positions. Look at the tasks needed to accomplish the goals of the unit and organization.
