When I configure the system so that only a person's manager can see his 360 degree feedback, what about the CEO, who doesn't have a manager? Who can see feedback about him?
Anyone who does not report to anyone else (e.g. the CEO) will be able to see their own feedback automatically, if you've selected for only managers to see feedback. Note that they still have to wait until the feedback release date has passed.
If you'd like to hide their feedback but keep the same settings, we'd recommend creating a separate cycle just for the CEO. Read more, here.
