By default, only the manager and more senior people can see the feedback given for an individual. You cannot, for instance, see the feedback that has been written about you.

If you've told nominees that their feedback is confidential, it's important that you keep it that way.

If you click the blue button, the Feedback tab will be removed. This will help to ensure you don't show the appraisee anything they shouldn't see if they're looking at your screen during the meeting.
