How should 3-level signoffs be handled with appraisal disputes?
Disputes should be handled first, before the Appraisee (and Appraisor for that matter) signs off. Disputes will generally come up DURING the appraisal interview, even before the Appraisor signs off. In other words, an Appraisee will/should NOT see the area of disagreement the first time when logging on AFTER the Appraisor has signed off.
